Rivers and Lakes Commission, S26 First National Bank Building, Chicago, III. Sirs : There is transmitted, herewith, a report covering the results of co-operative work between the Water’Resources Branch of the United States Geological Survey and the Internal Improvement, and Rivers and Lakes commissions of Illinois. Co-operative work with the Internal Improvement Commission of Illinois was first started in January, 1908. This report covers the period from January, 1908, to December 31, 1911. The investigations have been made in accordance with the regula¬ tions of the United States Geological Survey, under the general super¬ vision of M. 0. Leighton, Chief Hydrographer. Since March, 1909, the work has been carried on under my direct supervision, assisted by R. J. Taylor, W. M. O’Neill, EL J. Jackson, C. T. Bailey, and P. S. Monk, junior engineers. No two of these assist¬ ants have been engaged upon the Illinois work at the same time, except for short periods. Acknowledgements are due to these assistants for their interest and energy in connection with the execution of the work assigned to them. Especial acknowledgements are due Mr. Monk, who compiled practically all the data herein presented. I also wish to thank the members of the commission for their co-operation and interest in the work, and especially to acknowledge the assistance and unfailing courtesy of your secretary, Robert Isham Randolph. Yours verv truly, A. H. Horton, District Engineer 2 REPORT OF THE WATER RESOURCES INVESTIGATION IN ILLINOIS (By A. H. Horton. District Engineer, U. S. Geological Survey) SCOPE OF INVESTIGATIONS The co-operative work that has been done by the Water Resources Branch of the United States Geological Survey with the Internal Improvement and the Rivers and Lakes commissions consists of the measurement of stream flow entirely. Co-operative work was first started in January, 1908, and has been continued to date. Funds have not permitted of field work during this entire period, but the gaging stations have been maintained continuously', so that most of the stations have an unbroken record of gage readings for about four vears. In order to present these data to the public in their most useful form it was decided to publish a report containing all the stream flow data that have been collected in co-operation with the State of Illinois and all other published runoff data that could be obtained. In order to make this report of the greatest benefit it was decided to include other data directly or indirectly relating to stream flow. A brief outline of the contents of the report as prepared by the Water Resources Branch of the United States Geological Survey is given below. o 1/ o OUTLINE OF DATA IN REPORT STREAM PLOW DATA The runoff data from date of establishment to December 31, 1911, of the twenty-one stations being maintained under the co-operative arrangement are presented together with all other published runoff data available for Illinois streams. The data for some of the stations will be found to differ from that already published in the United States Geo¬ logical Survey Water Supply Papers and in the report of the Internal Improvement Commission of Illinois on Surface Water, 1908-1910, on account of revising the rating curves and obtaining a better value for the drainage areas of certain stations. Following the general description of the Mississippi and Ohio drain¬ age basins are tabular lists of all the stations along the Mississippi, Illinois, Desplaines, and Ohio rivers. These tables show for each sta¬ tion. so far as possible, its location, period of record, elevation of the zero of the gage, maximum and minimum reading, and bv whom maintained or published. 3 PRECIPITATION RECORDS All United States Weather Bureau rainfall records of 12 months or more in length at stations in Illinois are given. Plate I is a rainfall contour map of Illinois based on the mean annual rainfall from 1881 to 1910. EVAPORATION RECORDS Tables of evaporation from water surfaces, compiled from observa¬ tions in states subject to about the same climatological conditions as Illinois and from observations made in various parts of the United States are given, from which the evaporation from water surfaces in the State of Illinois mav be closelv estimated. RIVER PROFILES Tables of distances and elevations of the Mississippi and Ohio. rivers for the portions along the State of Illinois are presented, also the distances and elevations of a number of streams within the State. UNDEVELOPED WATER POWER The amount of undeveloped water power within the State is esti¬ mated. STORAGE The possibility of building large storage reservoirs is discussed. GAZETTEER A gazetteer of nearly five hundred streams in the State is presented. The location of the source and mouth and the direction of the flow are given. Also the drainage area above the mouth. DRAINAGE AREAS Following the gazetteer is a table giving the drainage area of Illinois streams of any size. The streams are arranged under the three primary drainage basins of the State so as to show to what stream each one is tributary. RECOMMENDATIONS FOR FUTURE WORK 1. (a) At present there are about twenty-one gaging stations being maintained in Illinois under the co-operative arrangement. These stations are on streams located in the central and southern part of the State. The data are primarily of use in studying drainage and flood control problems. These stations should be continued for a number of years longer, for the value of records of runoff increases directly as their length. Other stations should be established on streams where drainage and flood control are needed. (b) Gaging stations should be established on those streams in the northern part of the State on which there are water power possibilities. 4 (c) One or two stations should be established on the Desplaines and Illinois rivers so as to have records of the flow of these two streams. 2. There are no available records of evaporation at any place in the State. Observations of evaporation should be made in the northern, central, and southern sections of the State. 3. Profile surveys of those streams where drainage work is in progress or being contemplated should be made. ACKNOWLEDGMENTS In addition to the stream flow data obtained co-operatively, use has been made of stream flow records compiled by the United States Geological Survey in previous } r ears. Special acknowledgements are due the United States Weather Bureau for rainfall data; the United States Army Engineers for river profiles, data with reference to gages, and other information; the Office of Experiment Stations, United States Department of Agriculture, and the Topographic Branch of the United States Geological Survey for river profiles; J. A. Harman for data about the Kaskaskia River, and the East Side Levee and Sanitary District for runoff data of Cahokia Creek. PLATE II Small price current meters : 5 PART I, STREAM FLOW DATA STREAM FLOW DATA The work of compiling data relative to the available water supply has been carried on in accordance with the methods of the United States Geological Survey which have become standardized during the period of twenty years or more that the work has been carried on in various parts of the United States. In the performance of this work the endeavor is to approach as nearly as possible the highest degree of precision which a rational expenditure of time and a judicious expenditure of a small amount of money will allow. In all engineering work there is a point of refine¬ ment beyond which it is needless and wasteful to proceed, and this principle applies with especial force to stream-flow measurements. It is believed that the stream-flow data presented in this report are suffi¬ ciently accurate for all practical purposes. The data most liable to be in error for various causes are the estimates of runoff for low-water periods and the data for these periods should be used with care and caution. i METHODS OF MEASURING STREAM FLOW There are three distinct methods of determining the flow in rivers: (1) By measurements of slope and cross section and the use of Chezy’s and Kutter’s formula; (2) by means of a weir or dam; (3) by measure¬ ments of the velocity of the current and the area of the cross section. The first method is the least satisfactory and is rarely used by the Geological Survey. The second method is not suited to the majority of dams owing to leakage through the dam, intermittent use of dash¬ boards, uncertainty regarding co-efficient, uneven crest, and other reasons, and accordingly is not much utilized. The third method, that of measuring the velocity of the current and the area of the cross section of a stream, is the one that is generally used. In the selection of the gaging stations, care has been taken to locate them, so far as possible, at points where the relation between gage height and discharge remains constant for a given stage. A gaging station consists essentially of a gage for determining the daily fluctuations of stage of the river, and some structure or apparatus from which discharge measurements are made, usually a bridge or cable. The measurements of discharge are made by means of an electric current meter (Plate II). (For details of making the measurements the reader is referred to the annual stream-gaging reports of the United States Geological Survey.) A number of discharge measurements are 6 made at different stages of the river, so chosen that they will cover the range between high and low water as far as possible. These measure¬ ments are plotted on cross-section paper with the gage heights as ordi¬ nates and the discharge as abscissas. Through the points thus plotted it is possible to draw a smooth curve which is called the rating curve (Plate III). From this curve there is made a rating table showing the discharge for each gage height. The daily discharge is then obtained by applying the rating table to the mean daily gage heights furnished bv the observer. ACCURACY AND RELIABILITY OF RECORDS Practically all discharge measurements made under fair conditions are well within 5 per cent of the true discharge at the time of observa¬ tion. Inasmuch as the errors of meter measurements are largely com¬ pensating, the mean rating curve, when well developed, is more accurate than the individual measurements. The work is, of course, dependent upon the reliability of the observers, and in the case of controlled flow, upon the time of observa¬ tions. With relatively few exceptions the observers perform their work honestly. Care is taken, however, to watch them closely and to inquire into any discrepancies. In general in Illinois, observations are taken once a day, the single reading being considered the mean for that* day. In order to give engineers and others information regarding the probable accuracy of the computed results, footnotes are added to the tabulated data, and an accuracy column is inserted in the monthly discharge table. The accuracy column does not apply to the maximum or minimum or to any individual day, but to the monthly mean. It is based on the accuracy of the rating, the probable reliability of the observer, and knowledge of local conditions. In this column, A indicates that the mean monthly flow is probably accurate within 5 per cent; B, within 10 per cent; C, within 15 per cent; D, within 25 per cent. Special conditions are covered by footnotes. ARRANGEMENT OF DATA The rivers of the State are divided into three drainage basins; (1) Mississippi Biver basin, which is by far the largest as it comprises nearly 80-per cent of the entire State; (2) Ohio Biver basin; (3) Lake Michigan drainage basin. Practically all of the Lake Michigan drain¬ age basin in Illinois will be delivered to the Mississippi Biver basin upon completion of work in process of construction by the Chicago Sanitary District. The order of treatment of stations in any basin is down stream. After all stations from the source to the mouth of the main stem of the river have been given, the tributaries are taken up in regular order from source to mouth. For each drainage basin there is given a brief description of general conditions, covering such features as area, source, tributaries, topography, geology, etc. For each gaging station there are given the G/I6E HE/6HT //V FEE F PLATE III Discharge, area, and mean velocity curves 7 I following data, so far as possible: Description of station, list of dis¬ charge measurements, table of daily gage heights, rating table, table of daily discharge, and table of monthly discharge for each year that the station has been maintained. 8 UPPER MISSISSIPPI RIVER DRAINAGE BASIN GENERAL FEATURES Mississippi Eiver drains the greater part of the territory of the United States lying between the Allegheny and the Eocky Mountains. Its basin, irregular in shape, occupies the central part of the United States, and is best described as an oblong, with the major axis, 1,700 miles in length, running southeastward from the northwestern part of Montana, through North Dakota, Nebraska, Missouri, and Tennessee, into the northwestern corner of Alabama. On each side of this line the basin spreads out from 300 to 500 miles, and on the east is a large proturberance from the general outline extending to the Alleghenies. The basin comprises about 1,240,000 square miles, and includes wholly or in part 30 states, besides a small area in the Dominion of Canada. Of the total area, about 527,000 square miles drain to the Missouri, about 171,500 square miles to the upper Mississippi above the mouth of the Missouri, and about 204,000 square miles to the Ohio, leaving a balance of 337,500 square miles for the area between the mouths of the Missouri and Ohio and the area below T the Ohio. The mean annual flow of the Missouri is about 100,000 second-feet; of the upper Mississippi, about 125,000 second-feet; of the Ohio, about 300,000 second-feet. Immediately beneath the covering of drift at the sources of the Mississippi lie the oldest rocks known to the geologist. Its mouth is surrounded by the soft deposits of its own delta now forming. Between these two extremes rocks of all geologic ages are represented. All varieties of topography are likewise exhibited in the drainage basin, mountain and prairie, arid plain, and alluvial bottom covered ■with vegetation, being fully represented; but the greater part of its broad extent is very uniform in contour. For convenience in publication the basin of Mississippi Eiver has been divided into the upper Mississippi, Missouri Eiver, lower Missis¬ sippi, and Ohio drainage basins. The upper Mississippi basin, as con¬ sidered in this discussion, is that portion lying above the mouth of the Missouri, and that portion in Illinois between the mouth of the Missouri and the mouth of the Ohio. The upper Mississippi basin therefore occupies the north-central part of the United States, including Minne¬ sota, Wisconsin, Iowa, Illinois, Indiana, Missouri, and a few square miles in South Dakota and the northern peninsula of Michigan. The sources of this branch of the great river are almost exactly in the center of the continent on an east and west line. The Mississippi rises, not in Lake Itasca, long considered the source, but in a smaller lake called Hernando de Soto, which is situated 9 in the northeastern part of Becker County, Minnesota, and which drains into Lake Itasca through Nicollet Creek. From these lakes to the mouth of Crow Wing River it flows almost in a circle; at this point it is only 75 miles from its sources, while the distance following the river is 350 miles. Leaving the lakes its course is northward, but below the junction with the Crow Wing it turns to the south and con¬ tinues in this direction until it finally reaches the Gulf of Mexico. The total length of the river is about 2,555 miles; from the source to the mouth of the Ohio is about 1,500 miles. The important tributaries of the upper Mississippi, beginning at the source and following down the west bank, are Leech Lake, Willow, Pine, Crow Wing, Sauk, Crow, Minnesota, Cannon, Zumbro, Root, Turkey, Wapsipinicon, Iowa, Des Moines, and Missouri rivers; on the east bank are Prairie, Elk, Rum, St. Croix, Chippewa, Black, LaCrosse, Wisconsin, Rock, Illinois, Kaskaskia, Big Muddy, and Ohio rivers. From Lake Hernando de Soto to the Falls of St. Anthony the river flows almost exclusively through a drift-covered region. At the Falls of St. Anthony the river pitches down a vertical fall and rapids amounting to 80 feet in half a mile, and in so doing leaves the prairie and clay banks for a channel that lies between rocky bluffs of limestone and sandstone, which continue for many miles down the river, gradually increasing to a height of 500 feet as the bed sinks below the general prairie level. Minnesota River enters the Mississippi about 16 miles below St. Anthony Falls, and below its mouth the width of the main stream averages 1,000 feet. From this point to the mouth of the Ohio it is a broad, placid stream, containing innumerable islands, the entire width of the valley averaging 1 mile. In many places, especially where tribu¬ taries enter, fertile flats lie between the river and the bluffs. Fifty-five miles below the mouth of the Minnesota is Lake Pepin, an expansion of the river apparently caused by the immense quantities of sand brought down by the Chippewa. At two places exceptions occur to the otherwise placid character of the river. At Rock Island, Ill., 511 miles above Cairo, there are rapids by which the river falls about 20 feet in 12 miles; and at Keokuk, Iowa, 383 miles above Cairo, is the foot of the Des Moines Rapids, where in a distance of 11 miles the river falls about 22 feet. For a table of elevations along the State of Illinois see tables of profiles. The headwaters of the main stream and its tributaries which lie in Wisconsin and in Minnesota north of a line drawn diagonally through Douglas, Stevens, Meeker, McLeod, Sibley, Lesueur, Rice, and Dakota counties are in a region that was originally forested. Most of this area has been cut over extensively, and a comparatively small proportion has been cleared except in the southern part of the area where agriculture is making rapid strides. The remainder of the drainage area is prairie land. The soil of practically th^ entire basin of the upper Mississippi has been formed by the melting of the glaciers that once covered the northern part of the United States. The glacial deposit is of varying 10 thickness, being thinnest at the southern part of the basin and increas¬ ing in thickness towards the northern parts of the area. The winters in Wisconsin, Minnesota, and Iowa are severe; snow¬ fall is heavy throughout the greater part of this area, the snow lasts for ccmsiderable periods; ice forms to thickness of one to two feet, and lasts for three to four months. In the northern part of Illinois the winters are rather severe; the snowfall averages about 30 inches and the mean annual temperature is about 49°, the lowest winter tempera¬ ture being 32° below zero. In the southern part the winters are much milder; average snowfall is about 16 inches and the mean annual temperature is 56°, with the lowest winter temperature 16° in the extreme southern end of the State. The rainfall varies from 34 inches in the northern part to 40 inches in the southern part. According to some authorities the basin of the upper Mississippi contains from 5,000 to 6,000 lakes, nearly all of which are near the sources of the main river and its northern tributaries. In addition there are vast swamp areas in this region, so that there is great natural storage for steadying the flow of the river. This swamp land is begin¬ ning to be drained at the present time. By building comparatively low dams it is possible to create reservoirs on many of the lakes. The river is navigable as far up as St. Anthony Falls, and above that there are navigable stretches. The Army Engineer Corps has built five reservoirs on the Missis¬ sippi headwaters for the purpose of aiding navigation during the low water open season. These reservoirs have the following storage capacity: Feet head Cubic feet Wiimibigoshish. 14 44,000, 000, 000 33, 000, 000, 000 Leech Lake. 5. 7 Pokegama Lake. 7. 5 5 , 300^ 000; 000 3, 200, 000, 000 7, 700, 000, 000 Sandv Lake. 9.4 Pine River dam. 15.2 Although the reservoirs are operated primarily in the interest of navigation, water power and flood control are also benefited. The operation during the winter, or nonnavigation season, is based on the necessity for having 39,000,000,000 cubic feet empty storage capacity on April 1 to take care of the spring high water. Thus if the pre¬ ceding year has been very dry and the storage has been nearly exhausted, the reservoirs allow only the normal minimum winter flow (as deter¬ mined previous to building the reservoirs) to pass down the river. If the preceding navigation season has not drawn heavily on the reservoirs, the winter flow is increased by a sufficient amount to make possible the required empty storage capacity April 1. The length of the Mississippi along the western boundary of Illinois is 615 miles. In this stretch of the river water power is developed at two places; at Bock Island, Ill., 511 miles above Cairo, where about 10,000 horse-power is developed, but only about 4,000 horse¬ power are used: and at Keokuk, Iowa, 383 miles above Cairo, where there is in course of construction a concrete dam across the river, 4,700 11 feet long and 37 feet high. The ultimate power that will be developed is said to be 200 ; 000 horse-power. This plant is to be completed early in 191T The drainage area of the Mississippi Biver within the State of Illinois is 44,050 square miles. The following list includes the gaging stations on that portion of the river which forms the western boundarv of the State, and stations on the Illinois and Desplaines rivers, maintained by the Mississippi Biver Commission, United States Army Engineers, and by the United States Weather Bureau. Information with reference to these stations may be obtained upon application to the different bureaus named. Following the above list is a list of the gaging stations, data for which are published in this report.

BOCK EIYEE DBAINAGE BASIN GENERAL FEATURES The drainage basin of Bock Eiver lies in the southeastern part of Wisconsin and in the northwestern part of Illinois. The river rises in the southeastern part of Pond du Lac County in Wisconsin, flows in a slight southwesterly direction across the Illinois State line, and at Bockford, Ill., turns more to the southwest and joins Mississippi Eiver about 6 miles below the city of Bock Island, Ill. The total length of the river is about 286 miles. The total drainage area is about 10,820 square miles, of which 5,510 square miles are in Wisconsin and about 5,310 square miles in Illinois. The more important tributaries, beginning at the source of Bock Eiver, are East Branch of Eock Eiver, Oconomowoc, Bark, Turtle Creek, Kiskaukee, Kyte, and Green rivers on the left or east bank; and West Branch of Eock Eiver, Crawfish, Catfish, and Pecatonica rivers, and Eock Creek on the right or west bank. The drainage basin is irregular in shape, being about 175 miles in length, and about 85 miles in greatest width. In the upper part of 15 its course the river flows rather toward the eastern side of the basin, at the Illinois State line it approaches the center, and in its lower course it flows decidedly near the western boundary. The rocks under¬ lying this basin are limestones and shales, which have been in large part covered by the drift and morainic debris of glacial times, and the soils vary with the geologic formations on which they rest. The topography in the Illinois portion of the drainage area is an undulating, semiprairie region; in Wisconsin the surface is moderately hilly, elevations ranging from 750 feet where the river enters the State of Illinois to 1,100 feet on the crests of the Kettle Range. The rise from the interior of the valley is gradual, and few of the hill tops are more than 100 feet above the intervening valleys. The low, uneven topography has led to the formation of an intricate tributary system with numerous spring-fed lakes. These lakes occur chiefly in an eastern and western group, the eastern comprising about 20 lakes with an aggregate area of 11 square miles, and the western including 5 lakes with a total area of 13 square miles. The elevation of the source of the river is approximately 1,000 feet above sea level; at Horicon the eleva¬ tion is 858 feet; at the State line it is 731 feet, and at the mouth of the river 540 feet. The average slope is a little over 1 foot per mile. The forested area, according to L. S. Smith, of Madison, Wis., is about 30 per cent in that part of the drainage area in Wisconsin. The forested area in Illinois is probably less than in Wisconsin, as the State has been longer settled. The mean annual rainfall is about 35 inches. The winters in the northern part of this drainage area are comparatively severe, snowfall is heavy, and ice forms a foot or more in thickness on the streams. In the lotver part of the drainage basin the winters are somewdrat milder. The basin affords good opportunities for storage, but the value of the land that would be flooded by reservoirs prohibits their construction. Lake Ivoshkoning, an expansion of Rock River, 23 square miles in extent, is the only body of water now controlled in the interests of manufacturing. Although the average slope of Rock River is small, sites for wmter powder are numerous, as in general good foundations for dams may be found. A great many of the powder sites are fully or partly developed, but there are still undeveloped pow r er sites on the main stream and its tributaries. The power sites on the tributaries, with few exceptions, have small fall, and many developed sites have been abandoned because of the greater value of the submerged land for farms. 9 ° ^ ROCK RIVER ABOVE MOUTH OF PECATONICA RIVER AT ROCKTON, ILLINOIS Location .—At the highway bridge about three-fourths mile above O J o the mouth of Pecatonica River, about one mile from Rockton, Ill., and about one-half mile below T the dam at Rockton. Records available .—May 13, 1903, to August 18, 1903. Drainage area .—Three thousand six hundred and eighty square miles. Gage .—Standard chain gage attached to downstream side of left span of bridge. Datum has remained unchanged since establishment. 16 Channel .—Bed is of gravel; bridge is at an angle to thread of current. Discharge measurements .—Made from bridge. Floods .—No record of floods is available. Regulation .—A canal for power purposes diverts a large amount of flow around the station. Accuracy .—Considerable backwater effect from Pecatonica Eiver was experienced, and this, together with the large diversion, caused the situation to be discontinued.

ROCK RIVER BELOW MOUTH OF PECATONICA RIVER AT ROCKTON, ILLINOIS Location .—At highway bridge one mile below the dam and three- fourths mile below the mouth of Pecatonica Eiver. Records available .—May 13, 1903 ,to July 20, 1906; October 1, 1906, to March 31, 1909. Drainage area .—Six thousand two hundred and ninety square miles. « 17 Gage .—Standard chain gage attached to the downstream side of the first span from the left end of bridge. Datum .—The datum was changed October 1, 1906, so that the gage readings since that date read 1.0 foot less than they would bv the former datum. Channel. —Permanent; bed composed of gravel and small rocks; broken by four piers. Discharge measurements .—Made from upstream side of 5-span bridge. Floods .—The highest recorded stage during the period when the gage was in operation was 13.23 feet by the old datum. Xo other records of floods are available. Winter flow .—The winters in this vicinity are comparatively severe; « ice forms on the river but open places generally exist at the section. Ice jams are frequent below the station and cause backwater at the gage. Regulation .—The dam and power plant above the station may modify the flow during periods of low water. ‘ Accuracy .—Since the amount of the change in datum on October 1, 1906, is only approximately known, the estimates since that date are liable to some error. It is believed, however, that errors from this cause are small. There is a small amount of water diverted around this station for one or two small power plants.

ROCK RIVER AT STERLING, ILLINOIS Location .—At highway bridge in Sterling, Ill., about one-half mile below the dam of the Sterling Manufacturing Company, and five miles above the mouth of Elkhorn Creek. Records available .—January 5, 1905, to March 3, 1906. 28 Drainage area .—Eight thousand seven hundred and forty square miles. Channel .—There are two channels at all stages, separated by an island which is partly submerged at high stages. The highway embank¬ ment, however, does not overflow. Both channels are composed of gravel, free from vegetation, and are permanent. Gage .—A standard chain gage is attached to each bridge. The datum of the gage at the left channel is 0.48 foot below that on the right channel. Both datums have remained unchanged. The gages at this station were destroyed when the bridges were carried away by an ice gorge in February, 1906. Discharge measurements .—Made from upstream side of 5-span bridge over right channel, and 3-span bridge over left channel. Winter flow .—Ice conditions at intervals during December, January, February, and March, may affect the relation between gage height and discharge. Ice gorges occur below the station and cause backwater at the gages. Regulation .—The dam and power plant above the station may affect the flow at low stages.

ILLINOIS RIVER DRAINAGE BASIN GENERAL FEATURES Illinois River, the most extensive of all the tributaries of the tipper Mississippi, is formed by the union of the Desplaines and Kankakee rivers in Grundy County, Illinois, flows southwesterly across the State and enters the Mississippi at Grafton, about 24 miles above the mouth of the Missouri. Its drainage area of 28,210 square miles is distributed among three states, Illinois, Indiana, and Wisconsin; 24,040 square 33 miles are in Illinois, extending in a broad band 250 miles long, and averaging 100 miles in width, directly across the center of the State in a northeast-southwest direction; 1,020 square miles are in Wisconsin, extending north from the Illinois area; and 3,140 square miles are in Indiana, projecting east from the same area. The length, from the junction of the Kankakee and Desplaines to the mouth, is 267 miles. The most important tributaries are Fox, Vermilion, Mackinaw, Spoon, and Sangamon rivers, and Crooked and Macoupin creeks. The basin is level or undulating, the soil composed of glacial drift. In the broad strip across Illinois the soil is a rich black loam and com¬ prises some of the best farming land in the United States. The portion of the basin in Indiana is swampy. The Illinois River is important as an inland water route. In 1848 the Illinois and Michigan Canal was completed, starting from Lake Michigan at Chicago, entering the Desplaines Valley at Summit, cross¬ ing the Desplaines River at Joliet, and continuing along the right bank of the Desplaines and Illinois to Peru, where it enters the Illinois. From Peru to the mouth there is navigation, partly natural and partly by slack water from dams. This canal has now become nearly obsolete. The Chicago Drainage Canal, constructed as part of a deep waterway from the Lakes to the Gulf and for a sewage outlet for the city of Chicago, was opened in 1900. This canal consists of the dredging and enlarging of the South Branch of the Chicago River from its mouth to Robey Street, Chicago, the construction of a channel from that point to Loc-kport, a distance of 28 miles, and the deepening, enlarging, and leveling of the Desplaines River from Lockport to Joliet, so as to take care of the flow from the Drainage Canal in addition to the natural flow of the river. The flow in the Chicago Drainage Canal is limited by law to 10,000 second-feet. The flow up to the present time has been considerably .less than this amount. Upon completion of the construc¬ tion work in progress the flow will be in the neighborhood of the amount allowed by law. There are practically no forested areas in the basin. The mean annual rainfall varies from 36 to 40 inches; the mean temperature varies from 48° to 52°. The winters are somewhat severe; ice forms on the streams from one-half to one foot thick at times. The average annual snowfall is about 32 inches in the northern section and about 24 inches in the southern section. There are sites on the Fox and Kankakee valleys for storage reser¬ voirs, but the cost of land which would be flooded prohibits their con¬ struction. There is considerable water power available in the basin, much of which is used. Various sites on the Illinois and Michigan Canal have been developed by allowing the water to flow from the canal into the Desplaines and Illinois rivers. The large flow from the Chicago Drainage Canal and the heavy fall between Lockport and Joliet and below Joliet furnish opportunities for large power developments. The greater part of the power at these sites has been developed by the Chicago Sanitary District. 3 R L 34 ILLINOIS RIVER NEAR MINOOKA, ILLINOIS Location .—At the Elgin, Joliet and Eastern Eailroad bridge, a short distance below the Kankakee cut-off, six miles south of Minooka, Ill., two and one-half miles below the mouth of Kankakee Eiver. Records available .—January 1, 1903, to December 13, 1904. Drainage area .—Six thousand six hundred and sixty square miles. Gage .—Vertical staff gage attached to center pier of bridge. Graduations are in feet and tenths below the Chicago datum. Zero of Chicago datum is approximately 580.2 feet above sea level. Channel.. —Gravel, shifting on north side. Discharge measurements .—Made from the bridge and from a boat and cable about 25 feet above the bridge. Winter flow .—The river freezes over for considerable periods in December, January, February, and March, and affects the relation between -gage height and discharge. Regulation .—The flow at this station includes the flow from the Chicago Drainage Canal.

Records available .—March 10, 1903, to July 21, 1906. (See “Remarks.”) Drainage area .—Twelve thousand six hundred and eighty square miles. Gage .—Vertical staff gage fastened to the central pier of the bridge. Datum has remained unchanged. Elevation of zero of gage is approxi¬ mately 426.4 feet above sea level and 153.8 feet below Chicago datum. Channel .—Bed is gravel and silt; probably permanent; broken by six bridge piers. 44 Floods. —From a comparison with Weather Bureau records it is estimated that the flood of the spring of 1844 reached a height of 23 feet on the United States Geological Survey gage. (See “Bemarks.”) Discharge measurements. —Made from bridge. Winter flow .—The river usually freezes over for considerable periods during December, January, February, and March, and the relation be¬ tween gage height and discharge is thereby aflected. Regulation .—The natural flow has been increased by the Chicago Drainage Canal. Remarks. —The United States Weather Bureau has maintained a gage since 1884 on the highway bridge about one and one-half mile above the United States Geological Survey gage, and daily gage readings have been taken which are published in the Weather Bureau reports. A relationship between the United States Geological Survey and Weather Bureau gages could probably be established by comparison of the gage heights for the period when both gages were in operation, and the Weather Bureau gage heights changed so that the United States Geo¬ logical Survey discharge table could be applied to them to obtain the discharge for the period covered by the Weather Bureau gage heights. The estimates would be liable to error, due to changed conditions of flow at the sections before and after the period during which the United States Geological Survey gage was maintained.

The total length is about 135 miles, of which 50 miles are in Illinois. The drainage basin comprises 5,280 .square miles, of which . 2,140 square miles are in Illinois, and 3,140 square miles in Indiana. The most important tributaries are Yellow and Iroquois rivers. The basin is generally level, but near the State line a ledge of lime¬ stone runs across the valle} r and has so prevented the wearing down of the bed that a very large part of the drainage area in Indiana is a vast swamp, with ridges rising here and there. The entire marsh portion is devoid of rocks, except a few moraines containing scattered gravel and boulders. Below Momence, Ill., the basin is entirely different. The country is flat and there are no swamps. The river has not cut deep below the surface and the bed is largely of rock. The banks are generally high enough to prevent extensive overflow. There are no forested areas in Illinois, but the ridges in Indiana have a growth of scrub oak. The mean annual rainfall is about 34 inches and the average temperature is about 50.°. The winters are com¬ paratively severe, ice forming on the rivers from one-half to one foot thick during portions of the winter. The snowfall averages about 30 inches. There are but few, if any, suitable sites for storage reservoirs, and the cost of land that would be submerged prohibits their construction. The fall of the river about Momence is about one-half foot per mile, and this makes it of no value for water power. Below Momence, how¬ ever, the descent is about two and one-half feet per mile, and owing to the rock bed and suitable banks many dam sites are available. A number of water powers have been developed. The swamps act as a regulator by tending to keep up the low water flow. The swamps in Indiana are being drained and the channel of the Kankakee is being straightened so that the swamp area will be much reduced in a few years. It will be of interest to note the effect on the flow of the stream as the swamp areas are reclaimed. KANKAKEE RIVER AT MOMENCE, ILLINOIS Location .—At the highway bridge in. Momence, Ill., about one-half mile below the Chicago and Eastern Illinois Railroad bridge. Records available .—February 24 to December 16, 1905; February 21 to July 20, 1906. Drainage area .—Two thousand three hundred and forty square miles. Gage .—Standard chain gage attached to downstream side of second span from left bank. Datum remained unchanged during period of operation. Elevation of zero of gage is 5.38 feet above Momence city datum, which is 607.06 feet above sea level. Channel .—Solid limestone rock; permanent; river is divided by an island which begins one mile above and terminates about 500 51 feet below. There are two channels at all stages, most of the water flowing in the left channel. Discharge measurements .— Made from bridge. Winter flow .—No record of ice periods was taken. Accuracy .—The right channel is wide, with a rough bed, which may affect the accuracy of measurements at stages above the ordinary.

'520 360 425 0.182 0.14 DESPLAINES RIVER DRAINAGE BASIN GENERAL FEATURES Desplaines River rises in Racine County, Wisconsin, flows south, nearly parallel with Lake Michigan, to a point ten miles southwest of Chicago, Ill.; thence it turns southwest and flows about forty miles to its junction with the Kankakee to form the Illinois River. The basin is narrow in the upper part, gradually widening toward the lower por¬ tion; it comprises 1,316 square miles, of which 126 square miles are in Wisconsin, and 1,250 square miles in Illinois. The total length is about 110 miles, of which twenty miles are in Wisconsin. There are no im- portant tributaries. In Illinois the valley averages about one mile wide and consists of a rather shallow trough cut through limestone; this has only a thin covering of glacial drift, and the banks of the river are consequently very low. There are no forested areas in the basin. The mean annual rainfall is about 33 inches and the mean‘tem¬ perature about 48°. The winters are somewhat severe; ice forms from one-half to one foot thick on the streams during portions of the winter; the snowfall averages about 36 inches. The possibilities for storage in the basin are limited owing to the value of the land which would be flooded by reservoirs. The Illinois and Michigan Canal, which was completed in 1848, started from the Chicago River at Chicago, entered the Desplaines Valley at Summit, crossed to the right bank of the river at Joliet, and entered the Illinois River at Peru. This canal at present is used chiefly to furnish water for power plants situated along its banks. In 1900 the Chicago Drainage Canal was opened. This canal follows the route of the Illinois and Michigan Canal to Lockport, where it enters the Desplaines River. The river was deepened and widened from Lockport to Joliet so as to take care of the flow from the canal in addition to the natural flow of the river. Between Lockport and Joliet, a distance of eight miles, there is a fall of 52 feet in the Desplaines River. This fall, combined with the large flow from the drainage canal, makes available a large amount of water power; in addition, there is another oppor¬ tunity for power development in the southern part of Joliet. All of this power will be developed. At present the greater part of the power available has been developed and is being utilized at Chicago. « 55 DESPLAIXES RIVER AT RIVERSIDE, ILLINOIS This station was maintained from May 13, 1886, to December 31, 1899, by the Chicago Sanitary District and the Chicago Drainage and Water Supply Commission. Daily gage readings have been taken and occasional discharge measurements were made during that time, from which estimates of the daily flow have been made. The detailed data from 1886 to 1896 may be found in the Journal of the Western Society of Engineers, Yol. I, June, 1896. The highest authentic water mark indicates a maximum flow of 13,500 second-feet. The following data were taken from the 20th and 21st Annual Reports of the United States Geological Survey except that quantities have been expressed to three significant figures.

Its basin is about 130 miles long and averages 20 miles wide. The total length of the river, by map measurement, is 172 miles; the total drainage area is 2,590 square miles, of wdiich 900 square miles are in Wisconsin and 1,690 square miles in Illinois. The principal tributaries are White River in Wisconsin; Rock, Nippersink, Somonauk, and Big Indian creeks in Illinois; these are necessarily small from the shape of the basin. There are several lakes in the upper portion of the basin, the chief of which are Fox Lake and Geneva Lake. These lakes tend to regulate the flow to some extent. The basin is chiefly undulating prairie. The valley is a quarter of a mile to a mile wide, with sloping bluffs; toward the sources the valley is less deep than below. The entire basin is covered with glacial drift containing much limestone. Elevations above sea level along the stream are as follows: Pewaukee Lake, 848 feet; Waukesha, Wis., 794 feet; mouth, 460 feet. According to L. S. Smith, of Madison, Wis., about 30 per cent of the basin in Wisconsin is forested. There are practically no forested areas in Illinois. The mean annual rainfall varies from 30 inches in the northern part to 34 inches in the southern part. The mean tem¬ perature is about 47°. The winters in Wisconsin are severe, snowfall is heavy, and ice forms a foot or more in thickness on the streams. In Illinois, the winters are somewhat milder. There are a number of suitable reservoir sites in the basin at which storage might be developed, but the value of the land which would be flooded would probably prohibit their construction. The river has an average fall per mile of 1.4 feet in Wisconsin, and about 3 feet in Illinois. In the 6 miles above the mouth at Ottawa the fall is 5 feet per mile. There is therefore a considerable amount of water power available, much of which is used. FOX RIVER AT SHERIDAN, ILLINOIS t Location. —At Glen Park Highway bridge at Sheridan, Ill., about one mile below the mouth of Somonauk Creek. Records available. —September 20, 1905, to July 20, 1906.

SANGAMON RIVER DRAINAGE BASIN GENERAL FEATURES The drainage basin of Sangamon River lies wholly within the State of Illinois, very nearly in the center of the State. The river rises in the southwestern part of Ford County, flows southwestward to Decatur, in Macon County, thence westward to a point near Springfield, north¬ westward to its junction with Salt Creek at the northern boundary line of Menard County, and westward to its junction with Illinois River at the northern boundary of Cass County. Springfield is about twenty miles southwest of the center of the basin, which is roughly a right triangle in shape, with the mouth of the river opposite the vertical. The river is about 180 miles long, not including bends. The total drainage area is 5,410 square miles. The principal tributaries are Salt Creek and South Fork. I 70 The eastern third of the drainage basin is somewhat undulating and elevated, the rest of the basin is a level prairie. The soil is a very fertile, rich, black loam, especially adapted for raising corn. There are coal mines in the vicinity of Springfield. The bed and banks of the river are soft and insecure. The slope of the river is small. The elevation of its source is about 700 feet above sea level, and that of its mouth is about 430 feet. The only timber in this drainage basin is in small groves or along the river banks. The annual rainfall is about 37 inches. The winters are mild. Ice forms to some extent, and during severe winters attains considerable thickness. The basin contains many swamp areas and is so level and low that little ground storage is available. High water follows every heavy rain, floods are of frequent occurrence and considerable duration, and as the banks of the river are low large areas are flooded. The drainage of the swamps and the opening up of channels so that flood waters may have an opportunity of returning quickly to the main stream makes the study of flood control and drainage of considerable impor¬ tance. In some places short sections of the main stream are being straightened in an effort to provide a better channel so that floods will quickly drain off the adjacent land. Such work is of doubtful value, for in a few years at the most the river will return to its former channel or make new channels in order to keep in equilibrium. Any improve¬ ment of this kind should take into account the stream as a whole and should be begun at the lower end. On account of the low slope, floods, low water, and lack of suitable foundations for dams, opportunities for development of water power are lacking. SANGAMON RIVER AT MONTICELLO, ILLINOIS Location .—At Illinois Central Railroad bridge about one-half mile w T est of Monticello, Ill. Records available .—February 4, 1908, to December 31, 1911. Drainage area .—Five hundred and fifty square miles. Gage .—Standard chain gage attached to bridge; datum has re¬ mained unchanged since date of establishment. Channel .—Section is at a pool; measurements to date indicate that control is permanent. Discharge measurements .—Made from downstream side of bridge and wooden trestle approach. Floods .—The flood of May, 1908, reached a height of 15.2 feet on the gage. Winter flow .—Ice affects the relation between gage height and dis¬ charge during December, January, and February. 71 Discharge Measurements of Sangamon River at Monticello, Illinois, in 1908-11 Date Hydrographer Width Area of section Gage height Discharge 1908 Feet Square feet Feet Second-feet April 9 R.

SANGAMON RIVER AT RIVERTON, ILLINOIS Location .—At Wabash Railroad bridge about one-quarter mile west of depot at Riverton, Ill., about two and one-half miles below the mouth of South Fork. Records available .—February 13, 1908, to December 31, 1911. Drainage area .—Two thousand five hundred and sixty square miles. Gage .—Standard chain gage attached to bridge. Datum has re¬ mained unchanged since establishment. 78 Channel .—Slightly shifting; section is at' a pool and measurements to date indicate that the point of control is not changing; broken by two bridge piers. Discharge measurements .—Made from downstream side of 3-span bridge Floods .—The high water of 1883 reached a height of approximately 32 feet on the present gage. The high water of 1875 is said to have been y 2 foot lower than this. The high water of October, 1911, reached a height of 27.1 feet. ]Vinter flow .—Ice may affect the relation between gage height and discharge during December, January, and February; this will only occur during short periods of extremely cold weather as warm water from factories seems to prevent the formation of ice.

SANGAMON RIVER NEAR OAKFORD, ILLINOIS Location .—At highway bridge three miles northeast of Oakford, Ill., near the northwest corner of T. 19 N., R. 7 W., two and one-half miles above the Chicago, Peoria and St. Lonis Railroad bridge, and one and one-fourth miles above the mouth of Crane Creek. Records available .—October 26, 1909, to June 30, 1911, and December 10 to 31, 1911. Drainage area .—Five thousand square miles. Gage .—Standard chain gage attached to bridge; datum unchanged. Channel. —Shifting; the river for some distance above and below the station has been dredged and straightened, thus increasing the slope considerably and thereby disturbing the regimen of the river. Con¬ ditions along the improved section are probably reverting to their former natural state. Measurements to date, however, indicate little or no change in the relation between gage height and discharge. Discharge measurements .—Made from downstream side of bridge and wooden trestle approaches. Floods .—The floods of February and March, 1907, May, 1908, and October, 1911, reached a height of about 21 feet on the present gage. Winter flow .—Ice may affect the relation between gage height and discharge during portions of December, January and February. Regulation. —None. Accuracy .—There may be backwater effect at times, due to ice jams or drift lodging at the railroad trestle a few miles below the gaging station.

Drainage area ,—Four hundred and twenty-seven square miles. Gage .—Standard chain gage attached to bridge. On September 2, 1909, the gage datum was lowered 2 feet. The gage heights to August 10, 1909, refer to the old datum; those from August 11 to September 1, 1909, are of no value because of backwater from a construction dam built and used during that period. From September 2, 1909, to date, the gage heights refer to the new datum. Channel .—In August, 1909, a drainage ditch was dug along the river in this vicinity, straightening the course of the stream, but coin¬ ciding with the original channel at the gaging station. The cross- section of the channel was not changed at the measuring section, but the relation between gage height and discharge was considerably changed by the change in slope. The channel shifts to some extent but measure¬ ments to date indicate that the point of control is probably permanent. Discharge measurements .—Made from the downstream side of the bridge. Floods .—Maximum gage height since establishment of gage, 15.9 feet, occurred in September, 1911. No authentic record of floods prior to the establishment of the station is available. 92 Winter flow .—Ice may affect the relation between gage height and discharge during portions of December, January, and February.

Daily discharge January 6-18, and December 7-31,1909; January 1-27, February 17-28, and December 21-27, and 30 and 31,1910; and January 4-13,1911, estimated, because of ice conditions, from climatological records, discharge of adjacent drainage areas, and observer's notes. Mean discharge January 4-13,1911, estimated about 62 second-feet, varying from about 45-100 second- feet.

The creek rises in the southern part of and about on line between Montgomery and Macoupin counties, flows in a southwesterly direction diagonally across the southeast corner of Macoupin County and the northwest portion of Madison County, past Edwardsville, through East St. Louis, Ill., and empties into Mississippi River. 105 The creek is very crooked and its length is approximately 55 miles. Its basin is about 45 miles long, has an average width of about 8 miles and a maximum width of about 12 miles, and comprises 360 square miles. Its principal tributary is Indian Creek, which enters from the right bank about three-fourths of a mile north of the Wabash Railroad bridge near Poag, 111. The area drained is low, level, or undulating, and is crossed by a chain of bluffs just north of Poag, 111. The sources of the creek are about 680 feet, and the mouth is about 385 feet above sea level. The basin contains no forested areas. The mean annual rainfall is about 40 inches. In general the winters are mild. The opportunities for storage and water-power development have not been investigated but are undoubtedly not worthy of consideration. Flood control, especially in its relation to the proposed flood protection works of the East Side Levee and Sanitary District of East St. Louis, Ill., is the most important problem under consideration at present in connection with this drainage basin. c CAHOKIA CREEK NEAR POAG, ILLINOIS Local ion .—At the Wabash Railroad bridge about three-fourths mile northeast of the Wabash Railroad Station at Poag, Ill. Records available .—December 13, 1909, to December 31, 1911. Drainage area >—Two hundred and fifty-nine square miles. Gage .—Standard chain gage fastened to bridge; datum unchanged. Channel .—Probably permanent. Discharge measurements .—Made from downstream side of bridge. Floods .—Maximum gage height since establishment of gage 19.0 feet (discharge estimated about 3,600 second-feet), occurred in October, 1911. See footnotes to tables of daily gage height and daily discharge. No record of floods prior to the establishment of the gage is available. Winter flow .—Ice may affect the relation between gage height and discharge during short periods in December, January, and February. Remarks .—The data collected are being used by the East Side I* vee and Sanitarv District of East St. Louis, Ill., in its study for flood control and prevention at that place. Cahokia Creek will soon he diverted west into the Mississippi River north of East St. Louis instead of flowing into the river south of East St. Louis.

KASKAStvTA RIVER DRAINAGE BASIN GENERAL FEATURES Kaskaskia River, also called the Okaw, Illinois. The river rises in the center of lies wholly in the State of Champaign County, flows 110 southwestward. and empties into the Mississippi Biver in Bandolph County near the city of Chester, Ill. It is about 190 miles in length, not following the bends, but as it is very crooked, its length by course is not far from 400 miles. The total drainage area is about 5,710 square miles. It has few tributaries worthy of mention, the most important being Shoal and Silver creeks, which enter from the north at the lower part of the river. The drainage basin is long and comparatively narrow, the average width being about 30 miles, the maximum width about 60 miles. The ground is low, level, or undulating, and in consequence the slope of the river is small. The sources of the river are about 740 feet and its mouth is about 350 feet above sea level. The soil is mostly black loam. In the lower portion of the drainage area the soil gradually changes to a yellowish brown clay. The only rock exposure of any extent along this stream is found about 20 miles above Shelbyville. In this 15 or 20 mile section the banks and bed are largely of limestone or sandstone; elsewdiere they are mostly soft soil with some gravel. The basin contains no forested areas. The annual rainfall is about 40 inches. As a rule the winters are mild. Possibilities for storage have not been investigated to any extent. Opportunities for important w-ater-power development are entirely lacking. Because of the lowness of its drainage area, the basin affords little ground storage. During w r et weather the ground-w’ater plane rises to the surface, and the rains run off into the streams very quickly, pro¬ ducing very sudden rises and floods; in dry w r eather, as there is little or no ground-water stored, the flow of the stream becomes very small and in some places dries up entirely. The banks of the river are low, and in times of floods large areas are covered with water, delaying the planting of crops and at times destroying growing crops. Storage possibilities, land drainage, and flood control are subjects of considerable importance in this basin. KASKASKIA RIVER NEAR ARCOLA, ILLINOIS Location. —At highway bridge known as the “Bagdad Bridge” about four miles west of Areola, Ill., in the northeast part of T. 14 N., B. 7 E. Records available. —April 11, 1908, to December 31, 1911. Drainage area. —Three hundred and ninety square miles. Gage .—Standard chain gage attached to bridge. Datum has re¬ mained unchanged since date of establishment. Channel. —Probably permanent. Discharge measurements to date indicate that the point of control is permanent. Discharge measurements. —Made from dowmstream side of bridge. Floods. —The flood of May, 1908, reached a height of 17.3 feet on the gage. Winter flow— Ice affects the relation between gage height and dis¬ charge during portions of December, January, and February.

KASKASKIA RIVER AT CARLYLE, ILLINOIS Location. —At the Baltimore and Ohio Southwestern Bailroad bridge about one-fourth mile east of the railroad station at Carlyle, Ill. Records available. —March 2, 1908, to December 31, 1911. Drainage area. —Two thousand six hundred and eighty square miles. Gage .—Standard chain gage attached to bridge; datum unchanged. Channel. —Probably shifting. Measurements to date indicate that the point of control is probably permanent. Main channel is broken by three bridge piers and flood channel by four additional ones. Discharge measurements .—Made from downstream side of bridge. Floods .—The flood of 1882, which is the highest known, is said to have reached a height of 1 % feet higher than the flood of 1908, or 32.5 feet on the present gage. Winter flow. —Ice may affect the relation between gage height and discharge during portions of December, January, and February. Regulation. —A dam 3!/2 feet high and about 700 feet above the section is used for water supply purposes for the city of Carlyle. The average amount pumped is 3,500,000 gallons every 30 days, and during June, July, and August, 4,500,000 gallons every 30 days. The outfalls of one section of the city sewage system and some private sewers are above the section, so that the diversion is negligible.

Geological Survey Water Supply Papers Nos. 245, 265, and 2S5, and in the report of the Internal Improve¬ ment Commission of Illinois on Surface Water 1908-10, because of revising rating curve on account of discharge measurements made in 1911. 129 Monthly Discharge of Kaskaskia River at Carlyle, Illinois, for 1908-11 [Drainage area, 2,680 square miles] Month Discharge in second-feet Runoff— depth in inches on drainage area Accur- racy Maximum Minimum Mean Per square mile 1908 March (2-31). 9 150 1 630 5 940 2.22 2. 48 April. 6,870 l! 630 3,940 1.47 1.64 May. 19,900 4 770 9 540 3.56 4.10 June. 3,850 '590 l’ 220 . 455 .51 July. ’ 865 418 ' 568 . 212 . 24 August. 394 86 195 .072 .08 September. . 116 47 64.9 . 024 .03 October. 47 47 47.0 .018 .02 November. 47 47 47. 0 .018 .02 December. 86 47 59.6 . 022 .02 1909 January. 240 47 84 2 .031 .04 February. 6 , 420 280 2 500 .933 1.01 March. 7,940 1 070 3 280 1 . 22 1. 41 April. 11,700 7 815 6 880 2. 57 2. 87 May. 6,870 1 070 3,400 1. 27 1. 46 June. 4, 270 '865 2 640 .985 1 . 10 July. 6 ' 570 540 3 250 1 . 21 1. 40 Aujmst. 1,500 66 337 . 126 .14 September. 1 100 59 215 . 080 .09 October. 916 23 247 . 092 . 11 November. 3 850 175 1 620 605 . 68 December. 4,390 600 1,680 . 627 .72 The year. 11,700 23 2 170 . 810 11.03 1910 January. 6,720 916 3,790 1.41 1.63 February. 5,050 865 1,550 .578 .60 March. 10,800 615 3, 450 1. 29 1. 49 April. 1,390 394 ' 705 .263 .29 May. 6 , 420 690 2,920 1.09 1 . 26 June. 6 , 270 370 1,780 .664 .74 July. 4,270 540 1,640 .612 .71 August. 1,630 220 698 .260 .30 September. 2, 700 220 1,040 .388 .43 October. 6, no 280 1,620 .604 .70 November. 1,330 116 241 .090 .10 December. 2, 270 260 717 .267 .31 The year. 10,800 116 1,690 .631 8 . 56 1911 January. 3,800 994 2,140 .799 .92 A.

Records available .—February 26, 1908, to December 31, 1911. —9 R L 130 Drainage area .—One thousand nine hundred and eighty square miles. Gage .—Standard chain gage attached to bridge; datum has re¬ mained unchanged since establishment. Channel. —Somewhat shifting; section is at a pool and the point of control is apparently permanent. Discharge measurements .—Made from downstream side of bridge. Floods. —The flood of May, 1908, reached a height of 21.2 feet on the gage. Point of zero flow. —Not determined. Winter flow. —Ice may affect the relation between gage heights and discharge during portions of December, January, and February. Remarks. —The river is leveed along the left bank for some miles above and below the station. It is claimed that the levees, b} r confining the floods, cause unusual floods along the right bank, and law suits to recover damages have resulted. During extreme floods the levees some¬ time give way and so reduce the flood flow; this occurred during the floods of May, 1908, and October, 1911, flood water for several days passing around the gaging station. Former statements that all the flood water eventually passed the gaging station are in error.

The levee along the left bank broke during the flood of May, 1908, and on the morn¬ ing of October 3, 1911, letting considerable water flow around the section; consequently, gage heights for the May, 1908 flood, and from October 3, to about October 10, 1911, do not represent the true flow. The maximum stage of the October, 1911, flood was found to be 23.0 feet by leveling on the high water mark, and occured on the morning of October 3. The maximum stage for the May, 1908, flood was not deter¬ mined.

ILLINOIS Location .—At the Illinois Central Railroad bridge about 600 feet north of the railroad station at New Athens, Ill., about 1 mile below the mouth of Silver Creek and 3 miles above the mouth of Lively Creek. Records available .—January 23, 1907, to December 31, 1911. A record of river heights from January 23, 1907, to October 28, 1909, was kept by Mr. C. J. Yon Roth Roffy, the present observer, for the New Athens Journal. The river height was taken on Wednesday and Thurs¬ day mornings of each week, the river height for Wednesday being pub¬ lished Friday with the change in twenty-four hours as obtained from the river height of Wednesday. This record was kept for the informa¬ tion of farmers living on the west side of the river who were cut off from reaching town when the river reached a height of 30 feet. The record is authentic. The gage heights have been reduced to the present datum, the maximum error probably not being over 0.4 foot, decreasing as the stage increases. Drainage area. —Five thousand two hundred and twenty square miles. Gage .—Standard chain gage attached to the bridge; datum has remained unchanged since establishment. Channel. —Permanent; broken by one bridge pier at ordinary stages and three at high stages. Measurements to date indicate that point of control is permanent. Discharge measurements. —Made from downstream lower chord of bridge and from wooden trestle approaches. Floods .—The flood of the fall of 1898 reached a height of 34.5 feet by the present datum. 137 Winter flow .—The relation between gage height and discharge may be slightly affected by ice during portions of December, January, and February.

The vear. 6, S20 51 529 .696 9. 44 ---- SILVER CREEK NEAR LEBANON, ILLINOIS Location .—At highway bridge at Wright’s Crossing about 2 miles west of Lebanon, Ill., between the Baltimore and Ohio Southwestern and the East St. Louis and Suburban Railroad bridges across Silver Creek. Records available .—March 3, 1908, to December 31, 1911. Drainage area .—Three hundred and thirty-five square miles. Gage .—Standard chain gage attached to bridge, datum unchanged. From March 3, 1908, to May 10, 1909, the gage was so situated that 2 feet was the lowest obtainable reading, and the gage reader noted that the stream was dry whenever the water surface was below 2 feet. Upon inquiry he stated that the stream was dry for only one week during 1908; therefore, where the gage heights have been marked “Dry” during this period this note inserted “Dry under gage, cannot obtain gage height of water surface.” The position of the gage was changed on May 10, 1909, so as to obviate this difficulty. Channel .—Probably permanent. Discharge measurements .—Made from downstream side of bridge and small approach spans, and also, at high stages, from downstream side of three steel viaducts on road west of bridge. 150 Floods .—The maximum gage height since establishment of gage is 15.9 which occurred in May, 1908. No records of floods prior to the establishment of the station are available. Winter flow .—Ice may affect the relation of gage height to dis¬ charge during portions of December, January, and February.

The river rises in the northwestern part of Jefferson County, flows southward to the town of Zeigler, in Franklin County, thence west¬ ward to Murphysboro, in Jackson County, and then southward to its junction with the Mississippi about 40 miles above Cairo, Ill. Below 156 Zeigler the river is extremely crooked. The total drainage area is about 2,230 square miles. The principal tributaries are Beaucoup Creek, Little Muddy River, Caseys Creek, and Middle Fork Creek— all small streams of little importance. The drainage basin is elliptical in shape, with a major axis about 70 miles long and a minor axis about 50 miles long. The country is level or undulating. The soil is known as “mulatto soil”—a yellowish-brown clay. Winter wheat is the staple crop. The southeastern part is under¬ lain with valuable coal veins and coal mining is carried on quite extensively. The slope of the river is small. Its sources are about 710 feet, and its mouth is about 310 feet, above sea level. The banks and bed of the stream are soft and insecure. The area is timberless except for occasional groves and the growth along the banks of the streams. The mean annual rainfall is about 42 inches. The winters are mild. Ice does not form very thick, and, as a rule, the snowfall is light and does not last long. Storage possibilities have not been investigated, but owing to the growing demand for water in this section they should receive careful O O J attention. The basin offers no opportunities for power development. Like the other rivers in central and southern Illinois, this stream is subject to high Hoods and very low water. In some localities the high water overflows the land on each bank for 2 or 3 miles; some sections resemble a lake during floods. Backwater from the Mississippi fre¬ quently extends to Murphysboro, said to be 60 miles distant following the river, and floods reach the height of 30 feet above low water. It is possible that a canal will be constructed from the Mississippi to the coal fields that lie along the Big Muddy. It is thought that only one lock would be necessarv. Canal construction would probably be very t X v v simple, as the country is low and the material excavated very soft. BIG MUDDY RIVER XEAR CAMBOX, ILLIXOIS Location .—At the Chicago, Burlington and Quincy Railroad bridge about 1 mile north of Cambon Station and about 1% miles east of Plumfield, Ill., in Sec. 17, T. 7 S., R. 2 E., about ^4 mile below the mouth of the Middle Fork. Records available .—June 16, 1908, to-December 31, 1911. Drainage area '.—Seven hundred and thirty-five square miles. Gage .—Standard chain gage attached to bridge; datum has re¬ mained unchanged since establishment. c Channel .—Probably permanent. Discharge measurements .—Made from downstream side of bridge and wooden approach trestles. Floods .—Maximum gage height since establishment of The gage is 25.3 feet, which occurred in May, 1911. Xo records of floods prior to establishment of station are available. 157 Point of zero flow .—A determination by leveling Octobeer 25, 1911, indicates that there would be no flow past the station if the stream were to fall to about 1.4 feet by the gage datum. Winter flow .—Ice may affect the relation between gage height and discharge during portions of December, January, and February.

Records available. —June 17, 1908, to December 31, 1911. During 1908, the gage was read only when the observer happened to be in the vicinity. Except for a few days, however, fairly accurate results will be obtained if the discharge is interpolated on days when gage was not read. Drainage area. —Two hundred and twenty-seven square miles. Gage .—Standard chain gage attached to bridge; datum unchanged. Channel. —Probably permanent; poor for low water measurements because of low velocity and old piles in channel. Discharge measurements. —Made from downstream side of wooden trestle. Low water measurements made at wading section about 250 yards upstream. Floods .—The flood of 1902 reached a height of about 27.5 feet on the present gage. Winter -flow. —Ice affects the relation between gage height and dis¬ charge during portions of December, January, and February. Remarks .—The creek goes dry at times, the water then standing in pools near the gage.

GENERAL DESCRIPTION OF OHIO RIVER DRAINAGE BASIN The drainage basin of Ohio River lies in the central part of the eastern half of the United States. The river is formed by the union of Allegheny and Monongahela rivers at Pittsburg, Pa., and flows in a general southwesterly direction to its junction with the Mississippi at Cairo, Ill. The principal tributaries below Pittsburg from the north and west are Beaver, Muskingum, Scioto, Miami, and Wabash rivers; those from the south and east are Monongahela, Little Kana¬ wha, Kanawha, Guyandotte, Big Sandy, Licking, Kentucky, Green, Cumberland, and Tennessee rivers. The total length of the river is 967 miles; the total drainage area is about 203,000 square miles. The drainage basin of Ohio River comprises greater or less areas in the states of New York, Pennsylvania, Maryland, West Virginia, Virginia, North Carolina, Georgia, Alabama, Mississippi, Tennessee, Kentucky, Ohio, Indiana, and Illinois. Its northern boundaries are about 40 miles south of Buffalo, N. Y., its southern boundaries are within 300 miles of the Gulf of Mexico, and its eastern boundaries are about 225 miles from the Atlantic Ocean. The sources of the tributaries from the north lie in the glaciated area; those of the southern tribu¬ taries are located on the steep and rocky slopes of the western side of the Appalachian Mountains. The topography of the basin varies from flat and rolling in the western and northern portions to rough and mountainous in the southern and eastern sections. In general the rock floor of the valley is 30 to 50 feet below the level of the stream at low water. It is thought o 170 that in the whole length of the valley no rock barrier crosses its entire width at a level as high as the bed of the present stream. In several places rock shelves extend out part way across the river bed, leaving a channel deep enough for the passage of boats along the opposite bank. Notwithstanding the great number of riffles and shoals, the Ohio is generally navigable throughout the entire season for boats drawing less than 3 feet of water. It is navigable for vessels drawing 6 feet of water during a few months of the early part of the season, but there is usually little traffic with such boats after July. The canal at Louis¬ ville affords opportunity for passing around the rapids during low water. During high water stages the boats are able to pass over the rapids. The narrowness of the valley of Ohio Kiver has been a subject of remark from the early days of settlement. At very few places between Pittsburg and Louisville does its width exceed 2 miles, and usually it is scarcelv more than 1 mile wide. In the vicinity of Louisville its width is perhaps 4 miles, but below the mouth of Salt Eiver it narrows abruptly to about 1 mile, and remains narrow for nearly 100 miles. Beyond this narrow stretch it broadens out to a width of 6 or 8 miles, which it maintains for much of its course to Cairo, the only exception as it passes the elevated ridge below Shawrieetown, where its width is reduced to about 2 1 /? miles. The depth of the valley ranges from about 600 feet down to scarcely 100 feet, being greatest on the border of the “panhandle” of West Virginia and least in the lower portion of its course. Its depth seldom falls below 300 feet in the portion above Louisville and probably aver¬ ages 450 feet. The narrow portion below Louisville is about 300 feet deep. The broad portions at Louisville and in the lower parts of its course are but 100 to 150 feet deep. The average width between banks does not increase materially from Pittsburg to Cincinnati. In the long pool above the falls of the Ohio at Louisville the average width is much greater than that above Cincinnati, while just below the falls there is a considerable narrowing. Below this, the average width continues to increase toward the mouth of the river. The maximum width between banks is found about 20 miles above the mouth, where it is considerably more than a mile. There are many islands in the river—more than fifty above Louisville and about thirty below—ranging in size from a few acres to 5,000 acres. Many of them are cultivated and all are practically permanent in position. The elevation of normal low water at Davis Island Dam at Pitts¬ burg is 692 feet, and low water elevation at Cairo is 273 feet, a total fall of 419 feet, or an average fall of about 0.43 foot to the mile. The average fall of the portion of the river along the southern boundary of the State of Illinois is 0.32 foot to the mile. For list of elevations see tables of profiles. The northern and western portions of the drainage basin is defor¬ ested; the southern and eastern portions may be called partly forested, as large areas in the Appalachian Mountains at the sources of some of the southern tributaries are still covered with a heavy growth of 171 trees; as the tributaries are descended the cleared areas increase until the forested area is small. The mean annual rainfall in the basin is about 45 inches, ranging from 35 inches along its northern boundary to 70 inches in the south¬ eastern part at the sources of Tennessee River. The winters in general are mild; ice does not form very thick—on some tributaries hardly at all; the snowfall is light and does not last long. In the region about the headwaters of Allegheny River, however, the winters are severe. In quantity of discharge Ohio River is the main tributary of the Mississippi. Its mean annual discharge is about 300,000 cubic feet per second, which is much more than the discharge of St. Lawrence River at Ogdensburg, N. Y., although the drainage area of the St. Lawrence is nearly twice that of the Ohio. The maximum flow of the */ Ohio is approximately 1,500,000 cubic feet per second—about thirty times the low water flow. A comparison of records of flow of Ohio River with those of the upper Mississippi and Missouri shows that although its drainage area is one-third that of the combined Mississippi and Missouri its mean and low water flow is 1.3 times as great as their combined flow, and its maximum flow is 1.5 times as great. This fact is accounted for by the greater rainfall in the Ohio basin and bv the xJ O xj character of the basin. From the mouth of the Wabash River to the Mississippi River, a distance of 128 miles, the Ohio River forms the southern boundary of the State of Illinois. The drainage area of the Ohio River within the State of Illinois is 11,500 square miles. The following list includes the gaging stations on the portion of the Ohio River which forms the southern boundary of the State, and on the portion of the Wabash River along the eastern boundary of the State maintained by the Army Engineers and the Ignited States Weather Bureau. Information with reference to these stations may be obtained upon application to the Chief of Engineers, Lnited States Army, Washington, D. C., or to the Lnited States Weather Bureau, Wash¬ ington, D. C.

WABASH RIVER DRAINAGE BASIN DESCRIPTION The drainage area of Wabash River lies in Ohio, Illinois, and Indiana, slightly more than two-thirds of the area being in the last- named state. The Wabash rises in the southwestern part of Mercer County, Ohio, flows northwestward across the Indiana state line to Huntington in Huntington County, and thence slightly southwestward to Logansport in Cass County. At Logansport the river turns more to the southwest until it reaches Covington in Fountain County, where it finally turns south, continuing in this direction to Terre Haute, below which its course is slightly southwestward to its junction with Ohio River about 30 miles below Mount Vernon, Ind. From a point about 15 miles below Terre Haute to the mouth it forms the boundarv line between Indiana and Illinois. The important tributaries, beginning at the sources and following down the left bank, are Salamonie and Mississinewa rivers, Wild Cat, Sugar, and Raccoon creeks, and White and Patoka rivers; on the right bank are Little, Eel, Tippecanoe, Vermilion, Embarrass, Little Wabash, and Saline rivers. White River is much the largest tributary. The 173 length of the Wabash is about 410 miles (map measurement), and its drainage area comprises approximately 33,000 square miles; the area in Illinois is 8,770 square miles. The basin is regular in shape. Only a small part of the entire drainage area lies outside the glaciated region. The Wabash and the West Branch of the White lie within that area for their entire length. The East Branch of the White leaves the glaciated area in the lower part of its course, and enters it again about 20 miles above its mouth. All the rock formations are more or less covered with glacial drift in the form of sand and gravel ridges and till plains. In general the surface of the country is flat, with a general slope toward the south¬ west. In the unglaciated section in southern Indiana the country is more uneven. Bock outcrops at many places in the bed of the main stream and its tributaries. Along Little Wabash Biver, which enters the Wabash about 15 miles above its mouth, drainage and flood control are subjects of con¬ siderable interest. The Department of Agriculture is making a study of conditions with a view to developing a plan for reclaiming and pro¬ tecting areas that are overflowed during floods. Portions of the river have already been mapped for use in this study. The elevation of the sources of Wabash Biver is about 1,000 feet; at Huntingdon the elevation is 699 feet; at Logansport it is 583 feet; at Terre Haute, 478 feet; at the mouth of White Biver, 376 feet; at the mouth, 311 feet. The basin is thickly settled and highly cultivated, and the timber standing comprises only groves and woodlots, generally of small extent. The mean annual rainfall is about 40 inches. The winters in the northern part of the basin are comparatively severe. The snowfall is not heavy, but ice forms on the streams about 1 foot in thickness; in the lower part of the basin the winters are mild and ice does not form very thick. The high value of farm land in this section would undoubtedly prohibit the construction of reservoirs for storage. The main stream and its tributaries afford good opportunities for water power, especially the East and West branches of the White, where the fall is much more than on the Wabash. In general, the water power is not being developed. At the headwaters of Wabash Biver, in Mercer County, Ohio, is a large reservoir, called Grand Beservoir, that is used to store water which is supplied to the Miami and Erie Canal. This reservoir receives the drainage from about 200 square miles, and its capacity is about 4,000,000,000 cubic feet. The water that is thus fed to the canal is diverted from the basin of the Wabash Biver. The Wabash is navigable for part of its length. WABASI-I RIVER AT MT.

EMBARRASS RIVER DRAINAGE BASIN DESCRIPTION The drainage area of Embarrass River lies in the southeastern portion of the State of Illinois. The river rises in the central part of Champaign Count}-, near Urbana, flows in a southerly direction through Douglas, Coles, and Cumberland counties to the center of Jasper County, whence it takes an extremely tortuous but in general southeasterly course across Jasper Countv, the southwestern corner of Crawford Countv, and Lawrence County to its junction with Wabash River, about midway between Vin¬ cennes, Ind., and St. Francisville, Ill. Exclusive of the bends, its length is about 125 miles, and its drainage area comprises 2,410 square miles. Its most important tributary is Hickory Creek, or North Fork Creek, which enters from the left bank about 2y 2 miles below St. Marie, Ill. The sources of the river are about 730 feet and the mouth about 400 feet above sea level. The basin is long and narrow, with a length of about 100 miles and a fairly uniform width ranging from 15 to 30 miles. The surrounding country, which is level or gently rolling, is diversified by some small hills along the river. In the lower part of the basin, in the vicinity of St. Marie, the soil is sandy along the river; farther north and west it is the familiar black loam. To the east the soil is a light colored clay, which was formerly covered with a heavy growth of “water oak.” Near Oakland, in the upper part of the area, a sandy red soil occurs near the river and black loam away from the river. A mile back from the river on either side is prairie country. In the southwestern part of the basin, west of Lawrenceville, there are extensive oil fields. The chief crop in the valley of the Embarrass is corn. Some wheat is also grown. Forested areas are lacking in this basin. 177 The mean annual rainfall is about 40 inches. The winters are, as a rule, mild, the snowfall extending over a period of about two months and lasting onlv a few da vs at a time. For about a month ice in the river is 3 or 4 inches thick. During periods of extreme drought there is little flow in the river, for there are po springs in the basin and the ground-w^ater storage is insufficient to maintain the low-water flow. In wet seasons the ground becomes saturated, and heavy rains reach the river too rapidly for the streams to care for them. Large areas of bot¬ tom land throughout the entire length of the river are inundated by the floods, which cause a great amount of damage. Land drainage and flood control are therefore subjects of much importance and are now under investigation. Little drainage work has been done in the uplands, but the bottoms have been drained to some extent. Xo water power sites are available in this basin. The question of storage has not been studied. EMBARRASS RIVER NEAR OAKLAND, ILLINOIS Location .—At highway bridge about 2 miles northwest of Oakland, Ill., on the county line road to Hindsboro and Areola, in the northeast jiart of T. 14 X., R. 10 E., about 5 miles below the mouth of Brush Creek. Records available .—October 23, 1909, to December 31, 1911. . Drainage area .—Five hundred and thirty-five square miles. Gage .—Standard chain gage attached to bridge; datum unchanged since date of establishment. Channel .—The section is at a pool; measurements to date indicate that the control has not changed. Discharge measurements .—Made from downstream side of bridge. Floods .—The flood of 1897 reached a height of about 24 feet by the present gage datum. Point of zero flow .-*-Has not been determined. There was no flow past the bridge during a portion of the summer of 1908. Winter flow .—Ice may affect the relation of gage height to dis¬ charge during portions of December, January, and February. .

River frozen Jan. uary 1-12,1910, and January 4-13, 1911. Gage read to top of ice December 10 and 11, 22-23, and 30, 1909; January 8, 13-16, and December 25 and 26, 1910: January 4-11, 1911. July 15-September 6, 1911, observer reported a sand bar underneath gage. From July 15 to about August 19, 1911, the bar was probably covered by water and the discharge is fairly well represented by the gage heights. From about August 19-September 16, the observer reported “ Sand bar reading beneat h gage. ’ ’ During this period there was probably no water over the sand bar and the reported gage heigh ts do not give the elevation of the water surface. Minimum stage was aproximately 1.55 feet.

The river rises in the southwestern corner of Coles Countv, flows slightly southeastward, and discharges into Wabash Liver about 15 miles above its mouth, at the boundary line between White and Gallatin counties. Skillet Fork, its only important tributary, joins it not far above its mouth. The Little Wabash is about 150 miles long and its drainage area comprises 3,200 square miles. The elevation of the sources of the river is about 720 feet; at its mouth it is about 340 feet above sea level. The basin is shaped somewhat like a parallelogram with the long sides north and south. The country is level or undulating. • The soil, a rich black loam in the northern part, gradually changes into a yellow clay or “mulatto soil” in the southern part. There are no forested areas in this basin. The annual rainfall is about 42 inches. The winters are mild ; ice does not form very thick, and snowfall is light and does not last long. No water-power sites exist anywhere in this basin. The question of storage has not been investigated, though it is recognized as important in connection with the growing demand for water supplies and the general subjects of drainage and flood control. The United States Department of Agriculture is making a study of surface conditions with a view to formulating a plan for reclaiming and protecting areas that are overflowed during floods. Portions of the river have already been mapped for use in this study. LITTLE WABASH RIVER NEAR CLAY CITY, ILLINOIS Location. — At the Baltimore & Ohio Southwestern Lailroad bridge about 2 miles east of Clay City, Ill., and about 5 miles above the mouth of Big Muddy Creek. Records available .—October 3, 1908, to December 31, 1911. Drainage area .—Eight hundred and eight square miles. Gage .—Standard chain gage attached to bridge; datum unchanged. Channel .—Probably permanent. Location of point of control not known. Discharge measurements .—Made from downstream side of bridge. Floods .—The flood of February 8, 1909, reached a height of 23.7 feet on the gage. Winter flow .—Ice may affect the relation between gage height and discharge during portions of December, January, and February. Remarks .—The station is at the toe of a horseshoe bend in the river and the ground inside the bend along the railroad is very low. During high water the Little Wabash overflows into Little Muddy Creek and in extreme high water into Big Muddy Creek, forming at such times a sheet of water 4 miles wide along the railroad; the high water discharge at this station cannot, therefore, be determined. Eight measurements of discharge were made at this station during 1909-1911, but estimates are withheld because of impossibility of determining the high water discharge. 188 Discharge Measurements of Little Wabash River near Clay City, Illinois, in 1909-11 Date Hydrographer Width Area of section Gage height Dis¬ charge 1909 May 7 H.

MEASUREMENT OF RAINFALL The amount of rainfall is expressed in inches of depth upon a horizontal surface, snowfall being reduced to its equivalent amount of rainfall. The ordinary rain-gauge used by the United States Weather Bureau is illustrated in Fig. 1. /. OrJ/nary/fo/n-fua?*. Fig. 1 .—The diameter of the receiver A is 8 inches, the entire height of the instrument is 2 feet. The rim is beveled to a sharp edge and is accurately circular. The water which falls into the receiver runs down and through the funnel shaped bottom into the tube C, of one- tenth of the cross-section of the receiver; the amount of water collected is measured by inserting a properly graduated stick into the tube and reading the top of the wetted portion upon withdrawal. Large rain¬ falls overflow into the outer cylinder, which is used also for a collector of snow, the receiver A being removed during seasons of snowfall. While the actual measurement of the amount of rainfall is com¬ paratively simple it has been found that the position of the rain-gauge relatively to buildings, trees, or other objects, and its elevation above the surface of the ground, exerts a large influence upon the amount of water collected. Variations as large as 50 per cent have been observed, due to difference in location of the rain-guage. The greater the eleva- 206 tion the less the amount of water collected, due to the greater wind velocity at the greater elevation. For obtaining records of rates of rainfall, an automatic rain-gauge is used which gives practically a continuous record of the rainfall. RAINFALL RECORDS IN ILLINOIS The United States Weather Bureau has collected records at a large number of stations in the State of Illinois. In Table No. 3 will be found all the rainfall records of twelve months or more in length collected by the United States Weather Bureau in the State. There are included a few stations in the states adjoining Illinois. In all, there are 203 records included in this list; of this number, 191 are in Illinois, and the other twelve are in Wisconsin, Kentucky, Iowa, and Missouri. The five longest records and the mean annual rainfall for each period are given below: Station Length of record Mean Period Years annual St. Louis, Mo. 1837-1911. 75 39. 83 Muscatine, Iowa. 1846-1911. 66 37.58 Dubuque, Iowa. 1851-1911. 61 33.61 Peoria", Ill. 1856-1911. 56 34.78 Fort Madison, Iowa. 1856-1911. 56 37. 29 Table No. 2 contains an alphabetical list of all the rainfall records published in this report and the period covered by each record. In gen¬ eral, stations with 1911 as the limiting date are being maintained at present. ' Table No. 3 contains a list of the same rainfall records arranged according to drainage basins. Only the more important basins are used in the subdivision. It should be noted that the mean annual rainfall as given for each station in Table No. 4 is the average of the yearly rainfalls and is not the sum of the twelve monthlv means. The United States Weather Bureau, in computing the mean annual rainfall of a series of years, takes the sum of the monthly means as the mean annual rainfall, irrespective of whether or not the monthlv means are the means of the same number of monthlv values of the rainfall. RAINFALL MAP OF ILLINOIS On Plate No. 1 there is a map of Illinois on a scale of 12 miles to 1 inch, on which are shown lines of equal rainfall; location of all rainfall stations listed in Table No. 2; the location of all stream gaging sta¬ tions for which data are published in this report; the boundaries of the major drainage basins in the State, and of the more important minor basins. The rainfall contours are based on the thirty-year mean for 1881 to 1910; those records which are not thirty years in length were extended to the period 1881-1910 for comparative purposes, as, very evidently, it would be incorrect to compare records of unequal lengths, as for example, a fifteen-year mean rainfall with a thirtj^-year mean rainfall. All rainfall stations in Illinois and those stations near Illinois in adjoining states with records eighteen years or more in length sub¬ sequent to 1880 were taken as reference stations. There are thirty-nine 207 of these stations in all, twenty-one of which have records from 1881 to 1910. The average length of the records of the other eighteen stations is twenty-three years. The mean annual rainfall for each of these eighteen stations was extended to that for the thirty-year period, 1881- 1910, by Fournie’s method, which is based on the simple assumption that the ratio between the rainfalls of two stations, subject to about the same climatological conditions, is constant. Kainfall records of dif¬ ferent lengths may all be reduced to the length of any selected record by this method. For instance, if A and B are two rainfall records for the periods 1881 to 1910 and 1890 to 1910, respectively, and it is desired to obtain the mean annual rainfall at B for the period 1881 to 1910: Find the ratio of the mean for A from 1890 to 1910 to that at B for the same period; then, by applying this ratio to the mean at A for the period 1881 to 1910, the mean annual rainfall for B for the period 1881 to 1910 is obtained. The nearer the stations are together, and the nearer the length of the ratio determining period is to the length of the adopted period, the better will be the computed value of the rainfall, other con¬ ditions remaining the same. All rainfall records of ten years or more in length in the period 1881 to 1910 were used in drawing the rainfall contours. Each rain¬ fall station was located on the map, the reference stations being dis¬ tinguished from the others. It was found that the reference stations were well distributed over the State. All the rainfall records less than thirty years in length were extended to the period 1881 to 1910 by Fournie’s method, using the ratio as determined by a comparison of simultaneous records at the reference stations nearest to the stations in question; in some cases two or three values were obtained for one station by using the ratios from tw T o or three reference stations, the mean being taken as the correct value. After all the means were extended to the period 1881 to 1910, the values were entered upon the map and the contours drawn in the usual manner. Table No. 1 contains a list of all the rainfall records used in mak¬ ing the rainfall map. It shows the reference stations; the station from which each reference station was extended to the thirty-year mean where the reference station’s record was less than thirty years in length; and the stations whose records were extended to the thirty-year period grouped under the reference stations from which the comparative ratios were determined. The table also gives the mean annual rainfall for the record used or available; the length of the period in years; the period; the ratio of the mean of the available record of each station to the mean of the reference station for the same period; and, finally, the computed or derived mean for the period 1881 to 1910 for those stations whose records are less than thirty years in length, a comparison of the second and last columns will show the change made in converting mean annua] rainfalls for periods less than thirty years to a thirty-year mean. The maximum change shown is about 13 per cent. The mean annual rainfall at 142 stations in all were used in locat¬ ing the rainfall contours on the map. Of this number 39 are reference stations whose average length of records is 27 years, and 103 are stations whose average length of record is 17 years, whose mean annual rainfall for the period available was extended to the 30-year mean by Fournie’s method. I 208 The mean annual rainfall for the entire State for the period 1881- 1910 as determined from the rainfall map on Plate I is 37.4 inches. Table No. 1. All rainfall stations given in the following table were used in mak¬ ing the rainfall map. Stations for which comparative ratios are given are grouped under the respective reference stations from which such ratios were derived: Station Mean annual rainfall Length of record Ratio of mean in given period to the mean for same period of reference station Mean annual for 1881-1910 Years Period Inches Aurora. 35.9 30 1881-1910. 35.9 St. Charles. 36.6 15 1896-1910. 1.03 37.0 Beloit, Wis. 32.8 30 1881-1910. 32.8 Brodhead, Wis. 33.1 12 1898-1904; 1906-10 . 1.03 33.8 Delavan, Wis. 30.3 12 1887-8; 1892-8; 1908-10... .93 30.6 Blandville, Ky.

Part passes off immediately as surface flow into the streams and forms what may be called flood flow; a part is evaporated from the general surface of the ground; and a portion percolates into the ground. Of the last portion, a part is caught by the roots of vegeta¬ tion, passed upwards, and evaporated or transpired from the leaves, and a part passes on, downwards and laterally, finding its way to the surface again in the form of springs, which constitute the source of the dry- weather flow of streams, or it goes to maintain some artesian supply. The total flow of a stream is therefore, in general, equal to the rainfall less the evaporation; the flood flow is equal to the rainfall less evaporation and percolation; and, finally, the dry-weather flow may be considered as equal to the deeper or more permanent percolation. To enable stream flow data to be used in an intelligent way, it is therefore desirable to have a knowledge of the amount of evaporation and perco¬ lation. In general, the amount of percolation may be approximately determined by subtracting the flood flows of a stream from its total flow, providing the storage afforded by swamps, ponds, and lakes, is iu significant. The subject of evaporation naturally divides itself into two parts: evaporation from land-surfaces and evaporation from water-surfaces. The former is difficult to determine since the conditions affecting it are so varied and indeterminate. The subject is beyond the scope of this publication and has not been considered. For information on this sub¬ ject the reader is referred to articles by Greaves, FitzGerald, Harrison, Yermeule, and others. Evaporation from water-surfaces may be comparatively easily obtained by direct experiment. Considerable reliable data have already been published. Some of the data in the following tables have never been published before. By a judicious use of the data in these tables, it is believed that the evaporation from any water surface in the State of Illinois may be determined within 20 per cent of the true value, which is sufficiently close for most purposes. The United States Weather Bureau started a detailed study of the subject of evaporation in 1907. The methods and results of its works as far as published may be consulted in the following Monthly Weather Reviews: July, 1907, February, 1908, Annual Summary, 1908, Feb¬ ruary, April, and May, 1909, and February, 1910. There is also published in the Monthly Weather Reviews from June, 1908, to June, 1909, a very complete and interesting Annotated 307 Bibliography of Evaporation, by Grace J. Livingston, for the years 1670 to 1909. This bibliography includes not only titles but gives a sum¬ mary of each reference, which makes it of especial value. EVAPORATION RECORDS Records of evaporation from water-surfaces in Illinois are not avail¬ able. Tables Nos. 1 to 5 give the evaporation as observed in states adjoining Illinois or subject to about the same climatological conditions. Tables Nos. 6 and 7 contain data that mav be found useful in making comparative studies. The monthly percentages in Table No. 7 are of use in obtaining an approximation of the yearly evaporation from incom¬ plete yearly records. The following brief description of the different tables gives the general conditions under which the data were obtained. Table No. 1 .—At Iowa City, Iowa, the apparatus consists of two evaporation pans, 3 feet square and 18 inches deep, which are the standard dimensions. One of these pans is floated in the Iowa River near the shore by means of timbers. The other pan is set in the ground on top of the river bank a short distance from the river. A rain gage is located near the pan set in the ground. It is assumed in working up the evaporation from the floating pan that the rainfall is the same at both pans. The observations at the pan in the ground were not continued after 1909. The observations were made by Professor Arthur G. Smith. Table No. 2 .—At Columbus, Ohio, the apparatus consists of a standard evaporation pan floated by means of cylindrical floats at the center of a triangular shaped raft anchored in the reservoir of the city waterworks. The raft serves to protect the pan from waves, and as a support for the rain gage and for the observer while making the observa¬ tions. The observations are made by one of the city employees. Table No. 3 .—At Madison, Wis., the apparatus consists of a stand¬ ard evaporation pan floating in a marsh on the south shore of Lake Mendota. The reeds and grass were cut in the vicinity of the pan so as to allow the wind to have free sweep. The rain gage is located at the pan. The observations are made under the supervision of Professor L. S. Smith. Table No. J +.—At Grand River Lock, Wisconsin, on the upper Fox River, a standard evaporation pan is floated in a bayou near the locks. The rain gage is located 700 feet northeast of the evaporation pan. The observations are made by the lockmaster under the supervision of L. M. Mann, United States Assistant Engineer, Oskosh, Wis. Table No. 5 .—At Menasha, Wis., the apparatus consists of a standard evaporation pan floating in Little Lake Buttes des Morts, near the dredged channel. The rain gage is about 120 feet from the evapora¬ tion pan. The observations are made by the lockmaster under the supervision of L. M. Mann, United States Assistant Engineer, Oskosh, Wis. Table No. 6 .—At University, North Dakota, a standard evapora¬ tion pan is floated by means of a raft in a small pond on the campus of 308 the University of North Dakota. The rain gage is located about 160 feet from the evaporation pan. The observations are made under the supervision of Professor E. F. Chandler. Table No. 7 .—The data in this table, with the exception of Chest¬ nut Hill Reservoir, Boston, Mass., and Mount Hope Reservoir, Rochester, N. Y., were obtained from publications of the United States Weather Bureau, and are the results of a j-ears observations made during 1909- 1910. The records for Chestnut Hill Reservoir were obtained by Fitz¬ Gerald. For the summer months they are the means of ten years of observations, while for the winter months they are deduced from special experiments on the evaporation from snow and ice. The data at Mount Hope Reservoir were obtained by Kuichling since 1891, and are the means of two to eight years 7 observations. The values for these two stations as here published are taken from Turneaure and Russelks “Public Water Supplies. 77 The monthly percentages for the evaporation at Boston and Rochester being derived from the mean of several years 7 records are of value; while those for the other stations in Table No. 7, being derived from records of only a year or less in length, are not so valuable since the yearly evaporation varies considerably.

METHOD OF DETERMINATION" The undeveloped water power in 1 llinois is practically all located on the following streams: Rock River, Fox, Kankakee, Illinois, Desplaines below the entrance of the Chicago Drainage Canal, the Chicago Drainage Canal, and a few tributaries of the above streams. The streams in the central and southern parts of the State and the other tributaries of the Illinois River have no water power possibilities worthy of consideration. The fall on the above named streams was taken from the accom¬ panying profiles or from the best source at hand where profiles were not available. The stream flow, in second-feet per square mile, was determined from the accompanying records as far as available. Where the runoff data permitted, the flow used was obtained by taking the mean of the lowest two consecutive seven-day periods in each year. The natural flow of the Desplaines and Illinois rivers was determined and increased by 10,000 cubic feet per second, the amount of the flow in the Chicago Drainage Canal as allowed by law. The natural flow in the Illinois was taken from Water Supply Paper 194, p. 159, the “low” value being used. The rivers were divided into sections and the area above the upper and lower limits of each section determined and the mean taken as the area for the section. This area multiplied by the flow per square mile gives the discharge, which, with the fall, gives the theoretical horsepower. The figures in the table are based on an efficiency of 80 per cent for the water wheels. The amount of developed power in the summary is that determined by the investigations of the Rivers and Lakes Commission during 1911 and 1912. See the table of developed water power on page 370. SUMMARY OF UNDEVELOPED WATER POWER The following tabulation shows the theoretical horsepower, developed horsepower, and undeveloped horsepower for the streams on which are located practically all the water powers of the State. 324 WATERPOWER OF PRINCIPAL WATERPOWER STREAMS OF ILLINOIS Stream Theoretical horsepower^ Developed horsepower Undeveloped horsepower Rock River and major tributaries. 25,860 144,200 11,390 47,600 6,240 290 16 14,470 96,600 Illinois River, major tributaries and Chicago Dr. Canal.

The high value of land for farming purposes would prohibit the construc¬ tion of storage reservoirs even where natural conditions are favorable for their construction. A large amount of construction work is being done throughout the State to prevent the streams from overflowing into the natural basins along the streams and to drain the swamps which act as natural reservoirs in reducing the height of floods. It may therefore be stated that there are no opportunities for build¬ ing storage reservoirs in the State of Illinois for the purpose of con¬ trolling floods or regulating the flow of streams. STORAGE meant storage for the purpose of controlling floods flow of streams for water power purposes. The topo- is not adapted to the building of storage reservoirs 326 PART VII GAZETTEER. AND DRAINAGE AREAS OF ILLINOIS STREAMS GAZETTEER There are nearly five hundred streams included in this gazetteer, the location of which was taken from the following maps: Base Map of Illinois, 1909.-1910, scale 1" equals 7.9 miles; Provisional Geologic Map of Illinois, 1906, scale 1" equals 12 miles; Post Route Map, scale 1" equals 7.5 miles; Land Office Map, scale 1" equals 14 miles, and the United States Geological Survey Topographic Sheets, scale 1" equals 1 mile, very nearly. The length of each stream as given in the gazetteer was obtained by measurement on the maps and is only given for com¬ parative purposes, as the map measurement may be 50 to 100 per cent, depending upon the scale of the map, shorter than the true length. The drainage area of each stream above its mouth is given. The various forks or branches of different streams are described under the main stream and cross-referenced under the name of the fork or branch. For instance, South Fork of Sangamon River is described under Sangamon River (South Fork of), cross-referenced thus, “South Fork, see Sangamon River.” DRAINAGE AREAS Following the gazetteer there is a table giving the drainage areas of nearly all those streams included in the gazetteer; the drainage areas of some of the very small streams listed in the gazetteer were not measured. The total area of the State of Illinois, exclusive of Lake Michigan, is 56,272 square miles; of this area, 44,050 square miles is tributary to the Mississippi, 11,500 to the Ohio River, and 722 square miles to Lake Michigan, or, in percentage, 78.3, 20.4, and 1.3, respectively. These values do not take into account changing the flow of the Chi¬ cago River from Lake Michigan to Mississippi River drainage, but represent the drainage areas as they existed prior to the opening of the Chicago Drainage Canal. With the completion of works under construction by the Sanitary District of Chicago practically all of the Lake Michigan drainage in Illinois will be diverted into the Mississippi River drainage basin. The names of the streams are arranged from the sources down. For example, Sinsinnewa River is the most northern tributary of the Mississippi River in Illinois, Galena is the next one below, and so on. Following the area of a stream at the mouth and at other points, its tributaries are listed beginning at the sources; each tributary of a 327 tributary is treated in the same way. Tributaries being indented as shown in the table. For example, Otter Creek is a tributary of Sugar River which is a tributary of Pecatonica River which is tributary to Rock River which is tributary to Mississippi River. While the table of drainage areas is a duplication to some extent of the data given in the gazetteer, it is thought that the arrangement of the tributaries presents a more or less graphical representation of the different drainage systems, which will be found of considerable use in any study of Illinois streams. The drainage areas were measured on the following maps, the designating symbol as used in the table is given after each map: Base Map of Illinois, B.; Post Route Map, P.R.; Provisional Geologic Map of Illinois, 1906, G.; and the United States Geological Survey Topo¬ graphic Sheets, T.S.

W T here it was impossible to obtain the desired information by mail from any plant, it was visited by one of the engineers connected with this office. The information collected has been compiled in the table which follows. Table No. 1 gives the principal facts relative to the different plants arranged by rivers in the following order: The Mississippi River heads the list, and the plants on it are listed in descending order, beginning with those nearest PLATE V Dam at Rockford, Hock River PLATE VI Fox River at Algonquin - . PLATE VII Dam on Fox River at St. Charles 369 the source. Those streams discharging directly into the Mississippi are then arranged in the same sequence. The plants on these streams are also arranged in descending order. The same arrangement is observed in streams emptying into the tributaries of the Mississippi. In preparing this table, no measurements were taken, and other than a check with the published rating tables of the various turbine manufac¬ turers, the statements of operators for average actual horsepower developed were accepted. It was requested that these statements be based on years of normal flow. It was not found practicable to distinguish in the table between horse¬ power developed for a part of a day or for twenty-four continuous hours. —24 R L Table No. 370 r3 O pedofQA -ap d H 9§BJ3AY pBaq 3nt5fJOA\ 9§BJ8Ay s o a 8 -3 a id > 73 73 ►—t 73 73 , 73 73 73 73 S a > 71 2 5 73 PJ Ed 73 73 73 33 Pd • * • • 5 • , a ; > . • . 2 1 • • W is 1 • fc : : NH u ; a ■ ■ P ’ c£ • © • a : 'Otj a c — 2 < * 55 • K ! a ; a rc i- « • : : ^ ' 'rt * c ^ y , C3 h ; ; c . .

A concrete dam provides an average head of 13 jet, which is decreased at times by back water from the Mississippi. The mechanical installation consists of 6, 69" water turbines, each driving a 2400 T . 300 K.W. A.C. umbrella type generator at 72 R.P.M., and one 57" turbine, riving a 150 K.W. exciter unit. The water is led to the wheels through a head race of such dimensions as to provide a current of less than two feet per second. The power plant provides capacity for duplication of the present installation. The average output for a 13' head is about 2300 H.P. used in the operation of electric cars. ROCK RIVER AT ROCKFORD The method of development and the use of power at Rockford, Ill., is the same as that employed at Elgin, Aurora, Marseilles and some other manufacturing towns. A dam is built across the river by a corporation receiving the right from the proper authorities. The water is diverted from above the dam into raceways extending along the river bank on either side. The total flow is usually divided into a certain number of parts or shares. The different manufacturers interested in the power are located along the raceway, drawing from it their proportion of the flow through gates whose openings are regulated by a watchman employed by the different water use rs. Generally speaking, this method of developing power is wasteful. The large number of turbines employed and the number which are of antiquated design and poorly installed serve to decrease the power obtained from that which would be furnished by a single plant, with a small number of wheels of modern design converting the water power into electricity and distribut¬ ing it among the various owners. CHICAGO SANITARY CANAL AT LOCKPORT This installation utilizes the artificial flow of the drainage canal. An average head of 34 feet is available. Seven hydraulic turbines, each with a rated capacity of 6000 horsepower at the average head, are used to drive an equal number of generators rated at 4000 K.W. each. The current is gen¬ erated at 6600 volts stepped up to 44,000 volts and transmitted and delivered to a transforming station at Western Avenue. Here it is stepped down to commercial voltage and transmitted to various surrounding municipalities and industrial plants. . . In addition to the plants tabulated above, other installations are being contemplated. Plans for the development of a 15' head on the Fox River at Millhurst and a 6' head on the same river at Algonquin are under considera¬ tion. ,. „ The Illinois River in the reach of maximum declivity, extending from Lockport to Utica, will present, with the augmented flow of the Drainage Canal, an opportunity for the development of 126,000 horsepower at the turbine shaft. This has been fully set forth in various reports issued b\ the Internal Improvement Commission and the Rivers and Lakes Commission of this State. A Excepting those dependent on the fall or flow created by artificial chan¬ nels, Illinois does not present great opportunities for the development of water power. With few exceptions the installations are of low head. A marked change in the status of water power in this State lies in the passing of the small mills formerly to be found on nearly all of our streams. The extremes of high and low water, resulting from the extensive drainage operations carried out in the State, have removed the certainty of power, while the cutting away of the timber and the general introduction of gasoline engines, enabling the farmer to grind his own grist, have destroyed the trade which made such plants profitable. 374 PART II PRESENT STATUS OF DRAINAGE IN ILLINOIS The State of Illinois owes much of her wonderful wealth to the wide application of the principles of drainage to the vast swamp areas which extended over the State up to recent years. Measured in geological periods, the topography of Illinois is of recent creation. The receding ice sheets of the last glacial period deposited a thick layer of detritus over the major portion of the State, obliterating the original river systems, filling valleys and leveling hills. New river systems were forced to develop, and they have not yet had time to reach back, tap and drain the innumerable ponds, lakes and marshes formed and left without a natural outlet by the great retiring sheet of ice. In addition, Illinois is of low elevation with a mean some 260 feet lower than the average of the immediately surrounding states. Seventy-five per cent of her boundary is formed by rivers draining an area extending from the Great Plains and the Rocky Mountains to the ranges of the Appalachian system. The maps of the early surveys in this States indicate the existence of large areas of swamps. An account of the expedition led by George Rogers Clark from Kaskaskia to Vincennes in 1779 indicates that the path lay waist deep through an almost continuous swamp. The course of Clark and his men lay across land which is today in the heart of our famed corn belt. Richly productive farms and prosperous homes now cover the area designated as swamps on our early maps. The removal of the stagnant waters of the land-locked glacial lakes and marsh; the change from the swamps of 1879 to the richly productive farms of today, improvements which have multiplied land values, two, four, and even twenty times, and brought added riches through increased public health; these benefits have ail obtained through the broad development of our upland drainage. The effect of all this work today is that our uplands have been well reclaimed. Some work is still to be done, but the major portion has been performed. Public attention is now being directed to our river bottoms where a different condition presents itself. The purpose of drainage is to hurry the waters of excessive rain or melting snow from the land in question. But this act produces an artificial effect of our streams. Through the years of their natural formation the slope and capacity of our rivers have been adjusted by nature to accommo¬ date the flow existing when our swamps were still undrained. These swamps acted as reservoirs, and stored the excessive waters for gradual distribution through the following months of little rain, thus maintaining a fairly uni¬ form flow the year around. Under the new conditions, these reservoirs have been removed, and great quantities of drainage water are poured into the streams in a short space of time. Overflowing of the banks and flooding of the bottom lands result. Extremes of high and low water and frequency of flood formerly unknown are thus brought about. A county in this State whose river bottoms were flooded nine times in a single recent year furnishes an example. To reclaim our bottom lands in the most successful and economical way, those of each stream should be considered as a unit, in order that work done PLATE XII Spring Lake Drainage and Levee District; before completion 111X [tKLVMa Raising corn in Spring Lake Drainage and Levee District; work completed PLATE XTV Spring Lake channel, Spring Lake district PLATE XV Engineers dwelling and pumping plant; Spring Lake district 375 at one section may not hinder or make improvement impossible at another. Co-operation of all the land holders along any stream should be possible, and all impediments which stand in the way of such co-operation should be removed. There are about three million acres of bottom lands, subject to overflow within the borders of the State of Illinois today. Reclamation will increase these lands in value upwards of one hundred and fifty millions of dollars, besides giving an increment of more than seventy-five millions to our annual crop values, figured on a basis of corn and oats. Under intensive agricul¬ ture, this amount would be more than doubled. The benefit to the State through their reclamation is apparent. In connection with a general report on the Water Resources of the State' the Rivers and Lakes Commission determined to collect statistics of the present status of land drainage in the State. A letter was first sent to each of the county and township clerks in the State, asking for the name of each district and the name and the address of one or more officers of each district which might exist within the county or township. To the names thus obtained a blank form asking for the following information was sent: 1. Location. Township. County. 2. Name of district. 3. Name of officers: Commissioners with addresses. Civil Engineer. Attorney. 4. Date of organization. 5. Under what law organized. 6. Under what jurisdiction. County Court or Circuit Court. 7. Is the project completed? If not, give probable date of completion. 8. Did the project accomplish its purpose? 9. Lands under cultivation. Acres. 10. Area of lands occupied by levees. Acres. 11. Area of lands occupied by ditches. Acres. 12. Area of lands occupied by roads. Acres. 13. Area of lands occupied by pump plant. Acres. 14. Area of useful lands in district. Acres. 15. Total area. 16. How many miles of levee? 17. How many miles of tile? Give diameter. 18. How many miles of ditches? 19. How many miles of roads? 20. Give width and depth of ditches. 21. Give fall of ditch. 22. How is drainage affected? Pumping or gravity? 23. If pump plant, give size of pump or pumps. If pump plant, give size of engine or engines. If pump plant, give size of boilers. 24.

If the project consisted of straightening or changing the course of any stream, give the following: a. Name of stream. b. Location of dredged channel. c. Length of completed channel. d. Length of stream between upper end of dredged channel and lower end of dredged channel. e. Cross section of dredged channel. 29. What has been the cost of the improvement work of the district? Give total assessments made to date for construction. 30. What is the bonded debt of the district? 376 31. What is the annual maintenance tax of the district? 32. Are there any towns, cities or villages in the district? 33. Does the district care for sewage as well as surplus water? 34. In w T hat direction does the drainage water flow? 35. Has it been alleged that any real estate has been damaged by over¬ flow by reason of the construction, maintenance or use of any channel or ditch or levee or other works of the district? 36. Has any suit been started to recover such damages? 37. Has any judgment been recovered? 38. Are there any obstructions to proper and economical drainage of the lands of the district or conditions beyond the control of the district that should be removed or remedied by the State or Federal authorities? 39. Remarks. Here make any statement that would be of interest for publication relating to drainage. 40. Name and postoffice address of party supplying above information. Difficulty was experienced in obtaining full information of the various drainage districts. In some cases the efforts were viewed with suspicion, not easily removed. In others the local officers declined to furnish the in¬ formation gratis. Many districts have kept no record of money spent or of the amount of work done. Still others organized in the past have served their purpose and dissolved, leaving no records behind them. The data collected has been compiled and is presented in two tables which follow. Table No. I consists of a gazetteer of all drainage districts located in the State, giving insofar as possible the acreage of each district, the name and address of one officer of each, and stating whether or not the construction work in the district was completed at the time of the investi¬ gations. Table No. II gives total number of districts, total area, miles of tile, miles of open ditch, miles of levee and assessments for each county. The number of districts noted in Table II is not the total number of districts located in the county, but represents these of which complete information was obtained. The figures given as miles of tile laid do not represent all of the tile laid in the State, but rather the amount laid under direction of the different districts. In many districts the tiling is left to the individual land owners. The figures are not exact. Some districts may be omitted entirely, but it is believed that the tables generally present a good record of drainage work done in the State up to the month of May, 1912.

PLATE XVI Drainage ditch; Coal Creek district uax hoatw Lateral and main ditch; Coal Creek district PLATE XVT1I Cast Peoria district; before completion PLATE XIX Construction work in a drainage district PLATE XX Pumping plant; Bay Island district 393 This is evident from the text of the many replies received to Question No. 39 listed above. The need of many different reforms was urged by drainage engineers, attorneys and commissioners. The following suggestions are selected from those most frequently submitted: The most frequent complaint was against the present system of classify¬ ing land for assessment by jury, with the charge that juries are often not sufficiently acquainted with the benefits to be derived to enable them to give a fair calssification. It is urged that classification be made by a board of disinterested experts to be appointed by a judge of a court. Others state that under existing legislation it is possible for the opponent of a district to throw it into court on some trivial cause, often delaying work for years and resulting in excessive legal charges. Cases were cited where the legal expenses of a finally completed district actually exceeded the ex¬ penses of construction. Under the Act in force July 1, 1889, it is provided that any drainage district may be dissolved by petition of four-fifths of the land owners, repre¬ senting three-fourths of the acreage in the district. The expressed opinion of many interested in drainage matters is that the requirement of four-fifths of the land owners is excessive, as it enables a small minority to oppose the wishes of those representing by far the greater portion of the district. An example was given where four land owners are successfully opposing the wish of fourteen others to dissolve the district. The declaration by the Supreme Court that Section 40 y 2 of the Act of 1885, permitting drainage commissioners to collect the cost of bridges and culverts from the Road and Bridge Tax Fund, or from railroads, is uncon¬ stitutional, leaves the commissioners powerless to recover the expenses of such items. Several complaints were received in this matter. A suggestion made by two different commissioners is that the require¬ ment, under the law providing for the organization of special drainage dis¬ tricts that the annual meeting be held on the third Tuesday of November is unwise. In country districts the roads at that time of year are often in such condition as to render long drives a hardship and thus prevent a full vote. A great many complaints were received against the existence of two district drainage laws, the Act of 1879 and the Act of 1885. It was charged that these are conflicting in many details and have led to great confusion. Many remedies have been suggested, ranging from the repealing and recast¬ ing of the entire laws to revision by a board of experts. The concensus of opinion, as expressed, is that it would be better to have the two now existing laws recast into one of simpler form, which would make it possible to organize and conduct a drainage district, where the need for such exists, and to carry it through without the excessive delay, litigation and legal expenses so often involved under our present laws. Some of the above suggestions are of minor importance, but all indicate that imperfections exist in the machinery of our present drainage laws which should, in the proper order of things, be remedied. The drainage laws of this State should be turned over to a body of experts on this subject for careful study, and they should be revised or extended wherever conflicting or lacking in nature. Legislation should be drafted which will permit the organization of drainage districts to include all of the lands subject to reclamation in any of our river bottoms and pro¬ vide the means for their proper conduct along lines to follow the policy well established in this State, that all improvements of local nature shall be made by assessment or tax used upon the benefits derived. These are the principal demands of drainage today and they have been voiced by resolutions at practically every recent conference of those inter¬ ested in drainage matters. Model laws have been drafted in efforts to assist and encourage the desired legislation. Among these may be mentioned those developed by committees representing the National Drainage Congress, the Illinois Society of Engineers and Surveyors, and the Association of Drainage and Levee Districts of Illinois. These are all steps directed along the proper line. They indicate the need and should assist in obtaining the remedy.
