Department of the Interior, Canada, Reclamation Service, Ottawa, May 19, 1919. International Joint Commission, Washington, D. C, and Ottawa, Canada. Gentlemen : In accordance with the authorization of the Inter- national Joint Commission contained in its Order No. 157, made at New York City February 4, 1918, there are transmitted herewith records of flow of streams and canals in the St. Mary and Milk River basins, collected by the United States Geological Survey in cooper- ation with the United States Reclamation Service and by the Reclamation Service of Canada. Respectfully submitted. John C. Hoyt, Chief, division of surface waters, United States Geological Survey, E. F. Drake, Director, Reclamation Sei^vice of Canada. 7 WATER SUPPLY OF ST. MARY AND MILK RIVERS, 1898-1917. By B. E. Jones and R. J. Burley. AUTHORIZATION OF WORK. On January 12, 1918, the Secretary of the Interior suggested to the International Joint Commission that the commission should arrange for the compilation and publication of all stream-flow data collected at both the international and national stations in the Milk and St. Mary River basins, the data to be agreed upon by the United States Geological Survey, represented by John C. Hoyt, hydrauhc engineer, and the Irrigation Branch [now the Reclamation Service] of the Department of the Interior, Canada, represented by E. F. Drake, superintendent of irrigation, and to be published in the regular reports of the commission. The commission's favorable action on this suggestion was com- municated to the Secretary of the Interior under date of February 18, 1918, by Mr. Whitehead Kluttz, the secretary of the commission, who stated that a similar suggestion had been made by the Canadian superintendent of irrigation. Under the authority thus conferred on Messrs. Hoyt and Drake, Mr. B. E. Jones, hydrauhc engineer of the United States Geological Survey, was directed to compile the records collected in the United States, and Mr. R. J. Burley, chief engineer, drainage division, of the Canadian Reclamation Service, was directed to compile the Canadian records. SCOPE OF REPORT. Hydrometric work in the area drained by St. Mary and Milk rivers was begun in 1897, when the United States Geological Survey established a station on Milk River at Chinook, Mont. In 1898 this station was moved to Havre, Mont., about 20 miles upstream. In Canada records were first collected at a station established by the Alberta Railway & Irrigation Co. in 1905 on St. Mary River at Kimball, Alta. Additional stations have been established from time to time in both countries, and at the end of December, 1917, recol'ds had been obtained at 79 gaging stations on the main streams and their tributaries and at 4 1 stations on canals. 9 10 WATER SUPPLY OF ST. MARY AND MILK RIVERS, 1898-1917. Most of the records here assem])ied appeal^ as originally published in the reports of the Reclamation Service of Canada ^ and the United States Geological Survey, but some have been revised to free them from errors indicated by later data. The most notable need for such revisions was m the older estimates of winter flow, many of which, for stations on Milk E-iver, were based on inadequate data and have therefore been omitted from the compilation. Tables of daily discharge not heretofore published have been taken from the original records. DEFINITION OF TERMS. The volume of water flowing in a stream — the '^run-off" or '^dis- charge" — is expressed in various terms, each of which has become associated with a certain class of work. These terms may be divided into two groups — (1) those that represent the rate of flow, as second- feet, gallons per minute, miner's inches, and discharge in second-feet per square mile, and (2) those that represent the actual quantity of water, as run-off in depth of inches, acre-feet, and millions of cubic feet. The principal terms used in this report are second-feet, second- feet per square mile, run-off in inches, and acre-feet. They may be defined as foUows: '^ Second-feet" is an abbreviation for ''cubic feet per second." A second-foot is the rate of discharge of water flowing in a channel of rectangular cross section 1 foot wide and 1 foot deep at an average velocity of 1 foot per second. It is generally used as a fundamental unit from which others are computed by the use of the factors given in the tables of convenient equivalents. '"Second-feet per square mile" is the average number of cubic feet of water flowing per second from each square mile of area drained, on the assumption that the run-off is distributed uniformly both as regards time and area. "Eun-off (depth in inches)" is the depth to which an area would be covered if all the water flowing from it in a given period were uniformly distributed on the surface. It is used for comparing run-off with rainfall, which is. usually expressed in depth in inches. An "acre-foot," equivalent to 43,560 cubic feet, is the quantity required to cover an acre to the depth of 1 foot. The term is com- monly used in connection with storage for irrigation. The following terms not in common use are here defined : "Stage-discharge relation," an abbreviation for the term "relation of gage height to discharge." "Control," "controUing section," and "point of control," terms used to designate the section or sections of the stream below the gage which determine the stage-discharge relation at the gage. It should 1 Formerly Irrigation Branch, Department of the Interior, Canada. WATER SUPPLY OF ST. MARY AND MILK RIVERS; 1898-1917. 11 be noted that the control may not be the same section or sections at all stages. , The '^ point of zero flow" for a given gaging station is that point on the gage — the gage height — to which the surface of the river would fall if there were no flow. EXPLANATION OF DATA. The base data collected at gaging stations consist of records of stage, measurements of discharge, and general information used to supplement the gage heights and discharge measurements in deter- mining the daily flow. The records of stage are obtained either from direct readings on a staff gage or from a water-stage recorder that, gives a continuous record of the fluctuations. Measurements of dis- charge are made with a current meter by the general methods out- lined in standard textbooks on the measurement of river discharge. From the discharge measurements rating tables are prepared that give the discharge for any stage, and these rating tables, when ap- plied to the gage heights, give the discharge from which the daily, montlily, and jearlj mean discharge is determined. The data presented for each gaging station in the area covered by this report comprise a description of the station, a table giving results of discharge measurements, a table shov/ing the daily discharge of the stream, and a table of monthly and yearly discharge and run-off. If the base data are insufficient to determine the dail}" discharge, tables giving daily gage heights and results of discharge measure- ments are published. The description of the station gives, in addition to statements re- garding location and equipment, information in regard to any con- ditions that may affect the constancy of the stage-discharge relation, covering such subjects as the occurrence of ice, the use of the or tr earn for log driving, shifting of channel, and the cause and effect of back- water; it gives also information as to diversions that decrease the flow at the gage, artificial regulation, maximum and minimum recorded stages, and the accuracy of the records. The table of daily discharge in general gives the discharge in second-feet corresponding to the mean of the gage heights read each day. At stations on streams subject to sudden or rapid diurnal iTuc- tuation the discharge obtained from the rating table and the mean daily gage height may not be the true mean discharge for the day. If such stations are equipped with water-stage recorders tlio mean daily discharge may be obtained by weigliting discharge for parts of the day. In the table of monthly discharge the coUimii hejicied "Maximum" gives the mean flow for tlie day when th(^ menu gage heiglit was highest. Ab the gage height is the mean for the day it does not 12 WATEK SUPPLY OF ST. MARY AND MILK ER^ES, 1898-1917. indicate correctly the stage when the water surface was at crest height and the corresponding discharge was consequently larger than given in the maximum column. Likewise, in the column headed ^'Mini- mum" the quantity given is the mean flow for the day when the mean gage height was lowest. The column headed '^Mean" is the average, flow in cubic feet for each second during the month. On this average flow computations recorded in the remaining columns, which are defined on page 10, are based. ACCURACY OF STREAM-FLOW DATA.^ By N. C. Grover and J. G. Hoyt. DEGHEE OF ACCURACY REQUIRED. The laws relating to many natural phenomena have been reduced, to an exact science; those for many more are largely empirical and are based on experiments and assumptions that only approximate the truth. In the empirical class are included the laws of the science of hydrology and especially of that branch of hydrology which relates to the flow of water in open channels. It is possible, nevertheless^ by carefully considering the various factors, to reduce the incidental errors so that resulting records will be sufficiently accurate for tha purposes for which stream-flow data are required. In most problems two degrees of accuracy must be considered- first, that which is practicable or possible to obtain, and, second, that which is desirable or necessary. The obtainable accuracy of stream- flow data depends largely on the amount of money available for their collection. The desirable accuracy depends on the proposed use of the data. Stream-flow records have three principal uses — first, in predicting flow, generally in connection with the design of hydraulic works; second, in the immediate operation of hydraulic works; and, third, in studying conditions of past flow, usually in connection Vvdth the adjustment of water rights. For the second and third uses data as accurate as can be collected may be needed. In considering the first use, however, it should be remembered that both the total flow of a stream and its regimen change from year to year, and that the conditions existing at any particular time may never recur. For this use, therefore, reasonably accurate records that extend over a considerable period are much more valuable than extremely accurate data covering a short period. Studies of the accuracy of stream -flow data serve to determine the methods to be followed in their collection so that the records may meet the requirements of the proposed uses. Notes on accuracy that accompany stream-flow records should give, first, information by J Republished from Contributions to the hydrology of the United States, 1916: U. S. Geol. Survey Water-Supply Paper 400, pp. 53-59, 1916. •WATEE SUPPLY OF ST. MAEY AND MILK EIVERS, 1898-1917. 13 which the technical man may study the records and judge their ac- curacy, and, second, information by which both the general and the technical user may judge the reliability of the records without mak- ing a study. These two uses should be kept in mind in preparing the data as well as the notes. Consideration of the accuracy of records to be collected at any station should begin with the reconnaisance for the site and continue through the selection, establishment, mainte- nance, and operation of the station, the computation and interpreta- tion of the data, and the preparation of the records for publication. In other words, records should be collected with the desired degree of accuracy in view instead of leaving it to be determined after the field data are collected and estimates have been made. In this discussion of accuracy it has been assumed that personal or instrumental errors, both in field and office, are reduced to a negli- gible amount. In order that this assumption may be true, however, all operations connected with the work must be carefully conducted and instruments must be kept in proper working order. The conditions affecting accuracy may introduce errors that may be consistently compensating, consistently cumulative, or alternately compensating and cumulative. Therefore care must be taken to de- termine the way in which the incidental errors affect the results. CONDITIONS AFFECTING ACCURACY OF BECORDS OF DAILY DISCHARGE. The obtainable accuracy of records of daily discharge of a stream depends on the following factors, information in regard to which will determine the methods of operation and give a basis for evaluat- ing the records after they are collected: 1. Permanence of the stage-discharge relation. 2. Precision with which the discharge rating curve is defined. 3. Refinement of gage readings. 4. Frequency of gage readings. 5. Methods of applying the daily gage heights to the rating table to obtain the daily discharge. Permanence of the stage-discharge relation. — The permanence of the relation of discharge to stage as determined by the control is a fundamental factor in the collection of records of daily discharge of a stream. It may be disturbed either by a cliange in the control itself or by conditions that counteract the effect of the control, such as backwater from log or ice jams or floods in tributary streams below the station. The general character of the control and the con- ditions that may affect it are determined by inspection. The effec- tiveness of the control, however, can be finally determined only by plotting the results of discharge measurements. If sucli })lotting does not define a smooth curve the inconsistenc}'^ is duo to poor 14 WATEE SUPPLY OF ST. MARY AI?fD MILK RIMERS, 1898-1917. current-meter measurements of discharge, to instability of the con- trol, or to disturbing influences. If the control is unstable the ac- curacy of the record will depend on the number of the discharge measurements and their distribution as to time and stage. Errors due to lack of permanence of the stage-discharge relation may be either compensating or cumulative, according to the physical conditions affecting the nature and stability of the control.

Channel open part of February and March; determinations good. For January the record is fair. Discharge Apr. 1-8, 1902, estimated. Staj^'e-discharpe relation affected by ice and discharge estimated for following periods: Jan. 1 to Mar. 31 and Dec. 1-31, 1902; Dec. 11-31, 1903; Jan. 1-10 and Jan. 20 to Apr. 2, 1904; Jan. 1 to Mar. 1 and Nov. 26 to Dec. 31, 1905; Jan. 1 to Feb. 19 and Mar. 11-25, 1906; Jan. 1 to Mar. 31, 1907; Jan. 1 to Mar. 31 and Nov. 2i; WATER SUPPLY OF ST. MARY AND MILK RIVERS, 1898-191*7. 31 to Dec. 31, 1908; Jan. 1 to Mar. 12 and Dec. 25-31, 1910; Jan. 10 to Feb. 7 and Feb. 19 to Mar. 3, 1911; Jar. 1-5, 1912; Feb. 6-20, Dec. 1-19, 1913; Dec. 5, 1916, to Jan. 5, 1917; Jan. 21, 29-31; Feb. 1, 16-28; Mar. 1-11, 1917. See table of monthly discharge for estimates of mean flow for full months. Estimates of discharge for periods of less than one month, not shown on table of daily discharge, were as follows: Mar. 1-12, 1910, 120 second-feet; Jan. 10 to Feb. 7, 1911, 100 second-feet; Feb. 19 to Mar. 3, 1911, 80 second-feet; Feb. 6-20, 1913, 75 second-feet; Dec. 1-19^ 1913, 140 second-feet. Daily and monthly discharge recomputed Apr. 1, 1904 to May 31, 1905. The origmal estimate of mean discharge for March, 1907, was revised by means of discharge measurements Mar. 20 and 30 of that year. From Jan. 1 to some time in April, 1909, and Nov. 23 to Dec. 31 of the same year, stage-discharge relation affected by ice, but no estimates were made except Nov. 23-30, when the open-channel rating curve was used. Rough estimates of monthly means were based on weekly gage heights and open-channel rating curve. These means are given in the table of mean monthly discharge but were not considered sufficiently accurate to be included with the computed records for the year. The records for 1909 are, in general, un- satisfactory, as they do not check the results obtained on Swiftcurrent Creek near Babb, nor those on St. Mary River at Cook's ranch. In the previously published records for 1911 the daily discharge for Feb. 14 was given as 4 second-feet, with a note stating that this low stage was probably due to the water being held baok by the ice at the outlet of St. Mary Lake at the time the gage-height observation was taken and that the discharge for the day was probably considerably greater. The discharge for Feb. 14, 1911, therefore, has been estimated at 46 second-feet, which is the same as the discharge on Feb. 13 and 15. Jan. 1 to Mar. 25, 1912, ice present in stream, but open-channel rating was assumed applicable except Jan. 1-5, which was estimated. Oct. 1, 1915, Swiftcurrent Creek was turned into St. Mary Lake above the gage. Discharge Nov. 1-10, 1915, estimated at 70 per cent of flow at Kimball. Dec. 20-31, 1915, estimated mean 145 second-feet, or approximately CO per cent of flow at Kimball. Jan. 1-18, 1916, mean flow estimated 90 second-feet from flow at Kimball.

Note.— Oct. 1, 1915, Swiftcurrent Creek was diverted into St. Mary Lake above this station, and the dis- charge thereafter is not included in the above table because not comparable with the discharge previous to that date. The median flow given was obtained by arranging the monthly means in their order of magni- tude and taking the middle mean, or, if their number was even, the average of the two middle means. By using daily discharge a somewhat lower median discharge would be obtained. ST. MARY RIVER BELOW SWIFTCURRENT CREEK, AT BABB. MONT. Location. — In sec. 15, T. 36 N., R. 14 W., about a mile below mouth of Swiftcurrent Creek, at Babb, on Blackfeet Reservation, in Teton County. Drainage area.— 298 square miles. Records available.— July 14, 1901, to October 18, 1902; May 13, 1910, to September 30, 1915, when station was discontinued. Gage. — Stevens water-stage recorder on right bank opposite Babb post office. From July 14, 1901, to October 18, 1902, a staff gage on the left pier of a highway bridge about 100 feet above the location of the water-stage recorder, and at a different datum, was used; this gage was destroyed by the flood of June 5, 1908. From May 13, 1910, to July 18, 1911, a staff gage was maintained on the left bank about 75 feet below the original gage and at a different datum ; a temporary chain gage was used for low-water readings. From July 19, 1911, to April 21, 1915, an over- hanging chain gage was maintained on the right bank at the same datum and location as the water-stage recorder and at the same datum as the staff gage on left bank, but on account of conditions in the channel the gages on opposite banks did not read the same. Beginning January 1, 1913, separate gaging stations were maintained on St. Mary River and Swiftcurrent Creek overflow, and the results at the t^^'o stations were added to give the total flow of the river at Babb ; previous to that date only the gage on St. Mary River was read, the discharge of the overflow being included in discharge measurements. As the discharge of the overflow was a small part of the total flow and varied with the flow of Swiftcurrent Creek, ceasing entirely at low stages, only a small error resulted from this proi^odiiro. DiscHAR(rE measure.ments. — Made from the cable 50 feet above gage or by wading. Small overflow channel from Swiftcurrent Creek measured from a 'footbridge. Channel and control. — Bed of stream composed-of gravel and cobblostoiu^s; shifts slightly. A small overflow channel from S\\iftcurrent Creek enters about 100 feet below gage on left bank. ExTRHMEH oi' DiwHAHOK. — Maximum stago recorded, 6.5 feet July 4, 1902 (discharge, f),C)90 second-feet); minimum stage recorded, 3.48 feet March 15-25, 1912 (dis- charge, M second-feet). 36 WATER SUPPLY OF ST.

MARY AND MILK RIVERS; 1898-1917. 41 the discharge for February appears to be about 50 second-feet too large. Determinations of discharge Sept. 22 to Oct. 18, 1902, have been revised as original computations were based on incorrect gage readings. 1910, Dec. 24-31: Ice present at gage but open- water rating curve assumed applicable. 1911: Stage-discharge relation affected by ice Jan. 1 to Mar. 3 and Dec. 26-31; mean discharge Mar. 1-3 estimated at 95 second-feet and Dec. 26-31 at 65 second-feet. See table of monthly discharge for estimates for January and February. 1912: Stage-discharge relation affected by ice Jan. 1 to Feb. 5; discharge estimated as follows — Jan. 1-12, 80 second-feet; Jan. 13 to Feb. 6, 110 second-feet. 1913: Stage-discharge relation affected by ice Feb. 6-24; discharge estimated at 150 second-feet. 1914: Stage-discharge relation affected by ice Jan. 1 to Feb. 28; discharge estimated. Daily discharge also estimated for following periods, on account of unreliable gage readings due to disturbance of gage by high water: May 2-7, June 8-16, June 22 to July 20, Aug. 1-16, Aug. 21 to Sept. 17, Oct. 8-15, 21-31, Nov. 1-6, 23-30, Dec. 1-9 and 24-26. 1915: Stage-discharge relation affected by ice Feb. 10-18; discharge estimated. Oct. 25, previously pub- lished discharge believed to be high and has been revised by comparison with stations near Babb and near Kimball.

Note.— 1901-1902 and 1910 to Sept. 30, 1915, discharge obtained from records of St. Mary River below Swiltcurrent Creek at Babb. On Oct. 1, 1915, Swiftcurrent Creek was diverted into St. Mary Lake, and from that date on the records on St. Mary River near Babb were used. The run-off at the two points is nearly identical, Duck Creek being the only tributary between. In computing means for the period of record the means for the three partial months were considered the means for full months. The median flow given was obtained by arranging the monthly means in their order of magnitude and taking tho middle mean, or, if their number was even, the average of the two middle means. By using daily dis- charge a somewhat lower median discharge would be obtained. ST. MARY RIVER AT COOK'S RANCH, ALT A., NEAR INTERNATIONAL BOUNDARY. LocATiox. — In SE. ^ sec. 6. T. 1 N., R. 25 W. fourth meridian, at Cook's ranch, half a mile north of the international boundary, about a mile below the mouth of Boundary Creek, and 17 miles southeast of Cardston, Alta., Canada. Drainage area. — 452 square miles. Records available. — September 4, 1902, to December 31, 1912. The station was then moved to a point near Kimball, about 8 miles downstream, and a joint intei'iiational station was established. The discharge at the two points is prac- tically the same. Gage. — An overhanging chain gage fastened to a tree on the left bank, a quarter of a mile below Cook's house. From September 4, 1902, to June, 1908, an over- hanging gage about one-fourth mile upstream was read; this gage was washed out by the flood in June, 1908, and replaced July 27, 1908, at the new site. Discharge measurements. — Made from a cable one-fourth mile above gage. Channel and control. — Bed of stream is composed of gravel of medium size. Rapids just below gage; current swift at practically all stages. The banks not subject to overflow except during extreme floods, but the left bank is gently sloping, so that the stream is probably 200 to 300 feet wider at high than at low stages. Extremes of discharge. — Maximum stage recorded, 12.75 feet June 5, 1908 (dis- charge, estimated by comparison with record for station near Babb, 18.000 second - feet); minimum stage recorded November 19, 1904 (discharge by current-myter measurement 96 second-feet). Lower stages probably occurred during the winter months for which records of daily discharge are uot available. (See hydrograph, PI. III.) Ice. — Stage-discharge relation seriously affected by ice during winter montha. Diverson. — None during the period of this record. Regulation. — None. 44 WATER SUPPLY OF ST. MARY AND MILK RIVERS, 1898-1917. Accuracy. — Stage-discharge relation not permanent; affected by shifting control and ice. Records for 1909 do not agree with records obtained by Canada at Kimball, being from 10 to 37 per cent lower. They also appear low when compared with combined flow of St. Mary River above Swiftcurrent Creek and Swiftcurrent Creek; but current-meter measurements by W. A. Lamb made at Kimball, Alta., are much lower than the results obtained by Canada. Records at all four stations for 1909 should be used with caution. Records for October, November, and December, 1903, and June to November, 1904, appear low when compared .with the combined flow of St. Mary River above Swiftcurrent Creek and Swiftcurrent Creek. It is impossible to determine where the error lies, but as it is not very great it was thought best to base computations of the run-off at each station on the data obtained at that station. Considered as a whole the record is fair. Discharge measurements of St. Mary River at CooFs ranch, Alta., near international boundary, 1902-1912. Date. 1902. Oct. 11 23 1903.

MARY RIVER NEAR KIMBALL, ALT A., NEAR INTERNATIONAL BOUNDARY. Location. — In the SW. ^sec. 25, T. 1, R. 25 W. fourth meridian, about 1 mile south- west of Kimball post office, 1 mile southwest of the head gates and dam of the Alberta Railway & Irrigation Co.'s canal, and 14 miles southeast of Cardston, Alta. (See PL II, B.) Drainage area. — 472 square miles. Records available. — April 13, 1908, to December 31, 1917. History. — Station was originally established in 1905, by the Alberta Railway & Irri- gation Co., in the SW. i sec. 25, T. 1, R. 25 W. of the fourth meridian, about half a mile above the company's head gates. It was taken over by the Irrigation Branch, Department of the Interior, Canada, in April, 1908." Owing to lack of sufficient measurements and to the great changes in the channel and control caused by the flood of June, 1908, it has been found impossible to determine the discharge of the stream previous to June 21, 1908, although the gage heights are available for the intervening period. The United States Geological Survey maintained a station on the St. Mary a short distance north of the international boundary, for which records of flow are available from 1902 to 1912 and are included in this report under the heading "St. Mary River at Cook's ranch, near international boundary." In 1912 it was decided to combine these stations, provide the best possible equipment, and maintain and operate them jointly. A site was selected and a concrete gage house, equipped with a Stevens continuous water-stage recorder, was installed. This new station was used until the fall of 1916, when the forma- tion of gravel bars made it necessary to remove the equipment to a new site about half a mile farther up stream. A new cable station was erected above the new gage house and measurements have been made from it during the season of 1917. Gage. — Stevens water-stage recorder in frame shelter over concrete well, with vertical staff gages inside and outside well; winter readings obtained from a chain gage attached to a traffic bridge in SW. I sec, 1, T. 2, R. 25 W. fourth meridian. From 1908 to 1912 gage used was a staff in the NE. i sec. 25, T. 1, R. 25 W. fourth meridian ; from 1913 to 1916 the water stage recorder was in the NW. i sec. 25, T. 1, R. 25 W. fourth meridian. Observer for all gages, J. M. Dunn. Discharge measurements. — Open- water measurements made from cable 1,500 feet above gage ; winter measurements made from traffic bridge to which chain gage is attached. Channel and control. — Banks high and rocky; not subject to overflow. Bed com- posed of gravel and rock. Control formed by a ledge of rock immediately below gage shelter; at high stages a gravel bar forms part of the control. Stage dis- charge relation permanent at low stages; likely to shift somewhat at flood stages. Extremes of discharge. — 1908-1917: Maximum stage recorded, 11+ feet June 5, 1908 (discharge not determined); stage of 7.80 feet recorded June 22, 1916 (dis- charge, 8,620 second-feet); minimum stage, 5.42 feet February 5, 1914 (discharge, 70 second-feet). (See hydrograph, PI. IV.) Ice. — Stage-discharge relation affected by ice during winter. Diversions. — Water is diverted by the United States Reclamation Ser\'ice at a point near Babb, Mont., from St. Mary River to the North Branch of Milk River for the irrigation of lands in the lower Milk River valley and by the Alberta Railway- & Irrigation Co. at Kimball, 1^ miles below the station. Regulation. — The United States Reclamation Service has under construction a largo reservoir on the headwaters of Smftcurrent Creek, but as no water has yet been stored the stream-flow records have not been affected. Accuracy. — Stream bed and control shifted slowly butsleadil\- at site used from 1908 to 1912 and also at site of automatic gago and cable installed in 1913 for use of tlio M WATER SUPPLY OF ST. MARY AND MILK RIVERS, 1898-1917. United States and Canada. Stage-discharge relation at new site selected for gage and cables in 1916 permanent at low stages in 1917 but slightly shifting at higher stages. Rating curves well defined between 220 and 4,840 second-feet. Open- water discharge determined by applying mean daily gage height to rating tables; winter discharge determined from hydrograph prepared from discharge measure- ments and by comparison of maximum and minimum temperatures and gage- height graphs. Records good. IHscharge measurements of St. Mary River near Kimball, Alia., near international boundary, 1906-1917. Date. 1906. Sept. 22 1907, Aug. 3 1908. June 29 Sept. 1 10 1909.

Note.— Table summarizes stream-flow data for St. Mary River where it crosses international boundary prepared from records obtained by the United States at gaging station formerly maintained near the boundary, from records obtained by the Canadian Government at gaging station formerly maintained near Kimball, Alta. , and from recent records obtained at the station jointly maintained near Kimball by repre- sentatives of the two Governments. During the year 1917 water was diverted from St. Mary River at a point about half a mile below the outlet of Lower St. Mary Lake by the United States Reclamation Service St. Mary canal. This water, less the quantity lost by seepage, was delivered to the North Fork of Milk River. A large proportion of the seepage waters returned to St. Mary River, either above the station near the international boundary or by way of Rolph (Willow) Creek at a point between that station and the one near Lethbridge. The' fol- lowing table shows the water diverted from the St. Mary River drainage by the United States Reclama- tion Service St. Mary canal, exclusive of seepage losses from the canal: Month.

MARY RIVER NEAR LETHBRIDGE, ALTA.i Location, — In the NE. | sec. 26, T. 7, R. 22 W. fourth meridian, 8 miles southwest of the city of Lethbridge and 4 miles above confluence with Oldman River. Drainage area. — 1,394 square miles. Records available. — October 13, 1911, to December 31, 1917. Gage. — Stevens continuous water-stage recorder installed June 8, 1916; prior to that date a vertical staff graduated to hundredths of a foot; winter readings still obtained from the vertical staff. Staff gage read by W. D. Whitney. Discharge measurements. — Made from cable 1,680 feet downstream from gage. Channel and control. — Bed composed of coarse gravel. Right bank low and sub- ject to overflow at flood stages; left bank high and not subject to overflow. Control is a large gravel bar and is likely to shift during floods. Extremes of discharge. — 1911-1917: Maximum stage recorded, 3.91 feet June 22, 1916 (discharge, 8,964 second-feet); minimum stage recorded, 0.15 foot, October _ 5, 1913 (discharge, 46 second-feet). (See hydrograph, PI. V.) Ice. — Stage-discharge relation affected by ice during winter season. Diversions. — The United States Reclamation Service and the Alberta Railway & Irrigation Co. divert water from the river for irrigation above this station. Accuracy.^ — Stage-discharge relation permanent during open-water periods 1916 and 1917; fairly permanent 1911 to 1914; control shifted in 1915. Staff gage read daily to hundredths 1911 to June 7, 1916, and during winter periods. Operation of water-stage recorder not completely satisfactory throughout op en- water season of 1917, as shown by breaks in record. Daily discharge for open- water periods obtained by appljdng mean daily gage height to rating table; discharge for periods in which record was broken obtained by comparison with records obtained from stations on St. Mary River near international boundary; winter discharge ascer- tained from hydrograph based on daily gage heights, discharge measurements, and records of temperature.

Location. — In sec. 12, T. 35 N., R. 16 W., at outlet of McDermott Lake, at Many Glacier, in Glacier National Park, about 14 miles southwest of Babb, in Teton County. (See PL VI, A.) Drainage area. — 31.4 square miles (measured on Glacier National Park topo- graphic map). Records available. — ^June 6, 1912, to December 31, 1917. Gage. — Vertical staff on shore of lake about 75 feet from right end of outlet; prior to May 22, 1916, a staff gage on lake shore near left end of outlet. Discharge measurements. — Made by wading at outlet of lake or below the falls; high- water measurements made from highway bridge above power house ; section at bridge is very poor. From 1912 to 1914 high-water measurements were made from a cable at outlet of lake. Channel and control. — Limestone outcrop at outlet of lake; just below the control is a cataract. (See PI. VI, A.) Movement of a few small boulders scattered over the control is the only cause of change in rating curve. Extremes of discharge. — Maximum stage recorded, 4.75 feet June 17, 1916 (dis- charge, 1,530 second-feet); minimum discharge recorded, 8.7 second-feet April 1, 1913, by current meter measurement. The gage read 1.30 feet, but the stage- discharge relation was affected by ice. IcE. — Stage-discharge relation very little affected by ice. Diversions. — None. Regulation. — None. Accuracy. — Stage-discharge relation permanent except during an occasional period of high water when gravel and small boulders may lodge on control. Daily discharge ascertained by applying mean daily gage height to rating table. Records considered good. Discharge measurements of Swiftcurrent Creek at Many Glacier, Mont., 1912-1917. Date. 1912.

Note. — Average not computed if the monthly mean was not available for five years of more. Means for periods of 16 days or over assumed mean for the month. Means for less than 16 days not included when computing average and median values. The totals in acre-feet were not averaged' because the records covered different periods in different years. The medians given were obtained by arranging the monthly means in their order of magnitude arid taking the middle mean, or, if the number was even, the average Of the two middle means. By using daily discharge a somewhat lower median discharge would be obtained. WATER SUPPLY OF ST. MARY AND MILK RIVERS;, 1898-1917. 77 SWIFTCURRENT CREEK BELOW SHERBURNE LAKE DAM, MONT., Location. — In sec. 35, T. 36 N., R. 15 W., near outlet of Lower Sherburne Lake, in Teton County. (See PL VI, B.) Drainage area. — 64 square miles (measured on topographic map of Glacier National Park.) . • Records available. — July 1, 1912, to December 31, 1917. Gage. — Staff gage on left bank about 300 feet below the spillway of Sherburne Lake dam; read by employees of the United States Reclamation Service. From July 1 1912, to November 9, 1914, a vertical staff gage was maintained on the left bank near the outlet of the lake, and at a datum different from that of the present gage. Discharge measurements. — Made by wading or from cable 50 feet below gage. Channel and control. — An outcropping limestone ledge, somewhat broken and irregular, forms the control, and is subject to small changes. A landslide caused by the building of the dam has forced out the left bank a foot or so into the river channel. Extremes op discharge. — Maximum stage recorded, 7.85 feet June 17, 1916 (dis- charge, 2,280 second-feet); minimum stage, no flow December 22-28, 1917, owing to storage in reservoir above. Ice. — Stage-discharge relation not seriously affected by ice. Diversions. — None. Regulation. — The natural flow of the stream was affected from 1915-1917, by placing and removing flashboards on the temporary dam built at the outlet of the lake in connection with the construction of the Sherburne Lake storage dam. Accuracy. — Stage-discharge relation not permanent, owing to small movements of the gravel at the control during high water. A landslide, first noticed in 1917, has changed the control. Discharge measurements indicate the time and amount of the effect on the rating curve. Flow partly regulated by operation of gates. Records good.

Location. — In sec. 34, T. 37 N., R. 14 W., 50 feet above the road from Babb, Mont.; to Cardston, Alta., Canada, and about 2 miles north of Babb. Drainage area.— 50 square miles (measured on topographic maps). Records available. — Some discharge measurements in 1903-1912, and monthly estimates based on discharge measurements and scattered gage readings for June, July, August, and September, 1905. Discharge measurements. — Made from cable. Channel and control. — Bed composed of boulders; would shift only during floods. Diversions. — None. Regulation. — None. Accuracy. — Estimates of mean discharge for June, July, August, and September, 1905, given in a footnote to the table of daily gage heights, are based on a few scattered gage-height observations and several discharge measurements. As this stream is fed by melting snow its flow is fairly constant and the estimates are fair. Discharge measurements of Kennedy Creek near Babh, Mont., 1903-1907, 1911-12. Oct. Date. 1903.

Gage. — A vertical staff, graduated to tenths and nailed to upstream side of left pier of bridge; read once a day by ditch rider employed by United States Reclamation Service. Discharge measurements. — Made from upstream side of bridge at the gage. Channel and control. — Channel is uniform in cross-section but slope varies with the stage. Control is a V-shaped concrete drop a mile below gage. Extremes op discharge. — Maximum discharge recorded during the year, 254 second-feet. Regulation. — Flow is regulated at head gates, 26 miles above. A small reservoir at Spider Lake serves to equalize sudden changes at the head gates. Accuracy. — Stage-discharge relation practically permanent. Discharge computed by using a rating curve based on discharge measurements in 1918 and measure- ments of North Fork of Milk River at Peter's ranch, below outlet of the canal. Records fair.

Channel and control. — Bed and control composed of loose gravel, which is likely to shirt. High gravel banks, lined with concrete for few feet at section. 126 WATER SUPPLY OF ST. MARY Al^lJ MILK RI^^RS, 1898-1917. Extremes of discharge. — 1910-1917: Maximum stage recorded, 53 inches at flume No. 1 June 20, 1910 (discharge, 858 second-feet); minimum stage recorded, 0.55 foot October 17, 1911 (discharge, 18 second-feet). Regulation. — Discharge controlled by head gates 500 feet above station. Accuracy. — Stage-discharge relation practically permanent at the concrete measuring section at present in use or at the former station at the flume. Slight change in control at present station probably due to shift of gravel below measuring station. Gage readings apparently too few for close determination of mean daily discharge. Records fair.

Records previous to 1915 were taken at old flume just north of present stmcture. Gage. — Vertical staff bolted to left wall of flume; zero of gage level with bottom of flume. Gage read by J. M. Dunn. Discharge measurements. — Made ffom foot bridge spanning flume about midway from the ends and built for the purpose. Channel and control. — Rectangular flume 27 feet wide with 6ifoot walls. Accuracy. — Owing to the discharge being in an artificial channel the discharge meas- urements are considered accurate and the records good. This station was abandoned in favor of a more convenient site near the head gates at an artificial gaging section. (See description, pages 125-128.)

MAPvY AND MILK KIVERS, 18&8-1917. ALBERTA RAILWAY & IRRIGATION. CO.'S CANAL AT SPRING COITLEE, ALTA. Location. — In the NW. i sec. 28, T. 4, R. 23 W., fourth meridian, at Spring Coulee, about half a mile east of the railway station. (See PI. IX.) Records available. — Irrigation seasons May 1, 1914, to October 19, 1917. Gage. — ^Vertical staff set in bed of canal near left bank; read by F. H. Kelley. Discharge measurements. — Made from a cable 150 feet above gage. Channel and control. — Bed composed of sand, clay, and small stones. High clay banks; not subject to overflow, but likely to cave in and change control during and after high stages. Extremes of discharge. — 1914r-1917: Maximum stage recorded, 4.75 feet, July 1, 1914 (discharge, 638 second-feet); minimum stage recorded, 2.09 feet, July 4, 6, and 7, 1916 (discharge, 36 second-feet). Regulation. — Flow controlled by head gates at Kimball and by waste gates, by which water can be emptied into Pinepound creek, about a mile above gage at Spring Coulee. Accuracy. — Stage-discharge relation not permanent; affected by shifting of bed and caving banks. Gage read to hundredths daily. A few inaccuracies in observa- tions appear to have occurred during 1917. Daily discharge determined by apply- ing daily gage heights to rating table, and by shifting-control method. Records fair.

Note. — Means for periods less than a full month but exceeding 15 days were considered means for the month in finding average and median flow. Averages were not computed for January and February, as the period of record was considered too short. The totals in acre-feet were not averaged because the rec- ords covered different periods in different 5^ears. Figures showing maximum and minimum are for full months. The median flow was obtained by ar- ranging the monthly means in then* order of magnitude and taking the middle mean, or, if their number was even, the average of the two middle means. By using daily discharge a somewhat lower median discharge would be obtained. AVATER SUPPLY OF ST. MARY AND MILK RIVERS, 1898-1917. 155 SOUTH FORK OF MILK RIVER AT MACKIE'S RANCH, ALTA.

Right bank high, clean, and subject to overflow at extremely high water only: left bank low. Two channels at very low water. Control not permanent. Extremes of discharge. — 1909-1917: Maximum stage recorded, 8.50 feet Feb- ruary 17, 1916 (discharge, 3,467 second-feet); minimum stage, 1.75 feet February 9, 1914 (discharge, 1.0 second-foot). (See hydrograph, PL XI.) Ice. — Stage-discharge relation affected by ice during winter season. Regulation. — Flow at this station was affected in 1917 by diversion of water from St, Mary River to Milk River by the United States Reclamation Service. Accuracy. — Stage-discharge relation not permanent. Gage read to hundredths daily. Daily discharge for open-water periods obtained by applying daily gage height to rating table; winter discharge ascertained from hydrograph based on daily gage heights, discharge measurements, and records of temperature.

MILK RIVER AT EASTERN CROSSING OF INTERNATIONAL BOUNDARY, MONTANA. Location. — In NE. I sec .6, T. 37 N., R. 9 E. Montana principal meridian, at inter- national boundary, 30 miles north of Rudyard, Hill County, Mont., and 37 milea south of Manyberries, AJta., the nearest railway stations. (See PL X, B.) Drainage area. — 2,514 square miles (measured by engineers, Reclamation Service, Department of the Interior, Canada). Records available. — April 1, 1913, to December 31, 1917. From August 7, 1909, to April 1, 1913, station was maintained 1,000 feet upstream by Reclamation Service, Department of the Interior, Canada. Gage. — Gurley printing gage installed September 18, 1917, on right (south) bank, and referred to two staff gages, one inside in well, and one outside in trench. The station maintained by Canada from August 7, 1909, to April, 1913, was equipped with a staff gage and cable and was 1,000 feet upstream. Kennedy Coulee, a small dry coulee, is tributary between the two locations. This was made a joint inter- national station on April 1, 1913, when a staff gage was installed on the left (north) bank 200 feet below the present gage. This gage was used until August 13, 1913. Gages previously used as follows: April 1 to August 13, 1913, staff gage on left (north) bank, 200 feet below present gage; August 13, 1913, to March 22, 1917, Gurley print- ing gage referred to staff gage in river 10 feet below gage house; April 9 to June 13, 1917, several temporary gages were used, but all readings have been referred to the staff gage at the site of the one used August 13, 1913, to March 22, 1917; June 14 to September 18, 1917, readings on a staff gage at present site. Zero of gage on north bank was 2,696.58 feet sea level; that of present gage on south bank is 2,698.92 feet sea level. Staff gages read and automatic gages attended to by Frank Galloway. Discharge measurements. — Made from cable or by wading 100 feet below cable. Channel and control. — A bar composed of heavy boulders, gravel, and sand makes a decided riffle at medium and low stages, and shifts frequently. Extremes of discharge. — Maximum stage recorded, 9.60 feet April 9, 1917 (dis- charge, 4,860 second-feet); channel reported dry August 3-17, 22, 23, 1914. (See hydrograph, PI. XII.) Ice. — Stage-discharge relation seriously affected by ice during winter months. Short periods of open channel conditions may occur during floods. Diversions. — A few small diversions on the headwaters and tributaries. Regulation. — T^ow-water flow materially increased by water from ITuited States Reclamation Service St. Mary canal during July, August, and Septomhor, 1917.

MARY AITD MILK RIVERS, 1898-1917. 193 MILK RIVER AT HAVRE, MONT. Location.— In SW. i SW. i sec. 4, T. 32 N., R. 16 E., at highway bridge over Milk River at Ha\Te, in Hill County. Drainage area. — Not measured. Records available. — May 15, 1898, to December 31, 1917. Gage. — Chain gage fastened to doAvnstream rail of bridge. Owing to the foiTaation of sand bars in the river, it has often been necessary to move gage from one end of the bridge to the other, but the datum has not been changed. Discharge measurements. — Made from highway bridge or by wading. Channel and control. — Bed of stream composed of fine gravel and sand, shifting frequently. Both banks are overflowed at high stages. Extremes of discharge. — Maximum stage recorded, 17.2 feet March 12, 1916 (dis- charge not known); minimum stage recorded, channel reported dry July 16-18, 1898; August 16-20, 1904; July 25, August 18-26, 1905; November 16 to December 31, 1906; July 28 to September 14, 1910; July 29 to August 22, 1914. (See hydro- graphs, Pis. XIII-XIV.) Ice. — During the winter months the stream is completely frozen and the discharge is too small to determine except by discharge measurements. Periods of warm weather may cause sudden floods due to melting snow. At such times the open channel rating curve is applicable, except when an ice gorge forms below the gage. Diversions. — ^A few small diversions on the headwaters and tributaries. Regulation. — During 1917 the St. Mary canal was in operation, and a total of 33,600 acre-feet was added to Mlk River flow. Accuracy. — The United States Weather Bureau also maintained a station at this point and the gage is read by their observer or one of his sons. Frequent changes in the sand bars forming the control render a large number of discharge measure- ments necessary each year to insure good results. If one or two measurements are made each month the records are good; if fewer measurements are made the records are fair to poor. 123678°— 20 13 194 WATER SUPPLY OF ST.

Nov. 8-30, mean discharge estimated at 75 second-feet. 1913: Accuracy of gage-height observations for September and of the determinations of discharge based thereon are questionable. 1914: Channel dry July 29 to Aug. 22. 1915: Shifting-control method used to determine daily discharge from May to November 11. Discharge measurements were made frequently, but the results are 10 to 20 per cent lower than they should be to make them consistent with those obtained at stations above. Gage not read; discharge interpolated Nov 12-21. Discharge Nov. 23-30 estimated at 50 second-feet. 1916: Chinook winds and ice jams in February and March caused the river to rise rapidly, a stage of 15.9 feet being reached Feb. 21-22 and 17.2 feet Mar. 12, Flow not computed Nov. 11 to Dec. 31. Gage read alx)ut three times a week. Shifting-control method used to determine daily discharge Apr. 24 to May 3 and May 26 to July 3. 1917: Jan. 1 to Mar. 27, gage read about three times a week; flow not computed.

The minimum temperature in this locality in November was —14°, and in December it was —15°. This temperature would cause considerable ice to form in the river at the gage. 1899: Monthly means for May, June, July, August, and November, recomputed by interpolating between gage readings. Published records did not give weight to the time between readings.

Note. — Means for periods less than a full month but exceeding 15 days were considered means for the month in finding average and median flow. The median flow given was obtained by arranging the monthly means in their order of magnitude and taking the middle mean; or, if the number was even, the average of the two middle means. By using daily discharge a considerably lower median discharge would be obtained. The total yearly flow in acre-feet has been averaged because in general the period of record covers the open-water season and the flow during months for which records are missing was usually small. Mean flow for July. August, and September, 1917, obtained by subtracting the water diverted to Milk River by United States Reclamation SerAJ^ice St. Mary canal, A loss of 25 per cent was assumed between the outlet of the canal and Havre, and 8 days was assumed as the period of transit between the two points.

MILK RIVER AT MALTA, MONT. Location.— In NW. ^ sec. 17, T. 30 N, R. 30 E., at old highway bridge at Malta, in Phillips County. Drainage area. — Not measured. Records available. — July 31, 1902, to December 31, 1917. , Gage. — Chain fastened to guard rail on downstream side of bridge; read by employees of the United States Reclamation Service. The gage has been moved several times to different points on bridge, but datum was not changed. Discharge measurements. — Made from bridge or by wading, Channel and control. — Bed of stream composed of gravel; permanent except for slight shifts at low stages. Partial control at gage at low water, but the principal control is formed by a bar or ridge that produces a riffle half a mile below the gage. Extremes of discharge. — Maximum stage recorded, 19.75 feet April 10, 1917 (discharge, 11,200 second-feet); minimum stage recorded, channel reported dry August 13 to November 10, 1904; April 24 to May 8, and August 30 to end of year, 1905; April 10, 27-29, May 1, 4-23, 1906; July 16 to December 8, 1910. (See hydrographs. Pie. XVI-XVII.) Ice. — Stage-discharge relation is affected by ice during winter months. Generally the flow is low from December to the spring break-up, which comes in March or April. Warm periods during the winter may cause sudden rises. When this happens, the open channel rating curve can be applied except when there are ice jams below. Diversions. — Entire run-off from drainage basin above does not pass the station, for a large number of irrigation canals divert water from Milk River and its tribu- taries between Havre and Malta. The United States Reclamation Service has constructed a diversion dam (PI. XV) at Dodson, about 17 miles above the station. The Dodson South canal, heading at this point, has a capacity of 900 second-feet, and the Dodson North canal a capacity of 200 second-feet. PLATE XV. A.

MAEY AND MILK RIVERS^ 1898-1917. MILE RIVER AT HINSDALE, MONT. Location.— In the NE, i SW. i sec. 33, T. 31 N., R. 36 E., at highway bridge over Milk River about a mile from Hinsdale, a point 46 miles above junction of Milk River with the Missouri. Drainage area.. — Not.measured. Records available. — May 13, 1908, to November 13, 1914. On account of back- water the station was moved to Vandalia dam, about 8 miles downstream, in 1915, the flow at this point being practically the same as at Hinsdale. Gage. — Chain fastened to upstream side of highway bridge. Channel and control. — Bed of stream is gravel with a deposit of mud along the banks. Banks are high and are overflowed only during extreme floods. Water at the gage is deep and sluggish at low stages, due to a gravel bar 1 mile below, which forms the control. Discharge measurements. — Made from bridge or by wading. Extremes of discharge. — 1908-1914: Maximum stage recorded, April 6, 1912, discharge estimated at 24,200 second-feet; river reported dry August 9-13, 1910. (See hydrograph, PI. XVIII.) Ice. — Stream usually frozen entirely across and to a considerable depth from late iin November until the first of April, Diversions. — No water is diverted between station at Malta and that at Hinsdale. Above Malta numerous canals divert water from the main stream and nearly all the tributaries. I Regulation. — Some return water from irrigation increases the low-water flow during summer months. • Accuracy. — Stage-discharge relation permanent except during floods. Records good. \ Discharge measurements of Milk River at Hinsdale, Mont., 1908-1914- Date. 1908. May 14 27 June 9 25 July 8 Aug. 10 Sept. 28 1909.

Location. — In sec. 7, T. 30 N., R. 37 E., at Vandalia dam of United States Reclama- tion Service, 2 miles west of Vandalia in Valley County. (See PI. XIX.) Drainage area. — Not measured. Records available. — May 5, 1915, to December 31, 1917. Station maintained at Hinsdale, 8 miles upstream, from May 13, 1908, to November 13, 1914. Discharge nearly same at both points. Gage. — Sloping gage painted on concrete of right abutment downstream side of dam. Read twice daily to tenths by employees of United States Roclaniation SerN-icw it is diflicult to read gage closer than the nearest tenth as water conung through sluice gate and over dam (>auses waves at gage. 232 WATER SUPPLY OP ST. MARY AND MILK RIVERS, 1898-191*7. Discharge measurements, — ^Made from the bridge over crest of dam, from highway bridge at Vandalia about 2 miles downstream, or by wading. Channel and control. — ^Water surface at gage in large pool below dam is con- trolled by gravel bar at medium and low stages. This bar is drowned out at high stages. Both banks high; left is overflowed at high stages. Extremes of discharge. — Maximum stage recorded, 34.5 feet April 11, 1917 (dis- charge, 25,200 second-feet); channel reported dry August 9-13, 1910. (See hy- drograph, PI. XX.) Ice. — Stage-discharge relation affected by ice during winter season except for periods of high water. The flow during the winter is fairly constant and can be estimated from* the flow at Malta or from a few discharge measurements and daily gage heights. Diversions. — Numerous canals divert water for irrigation from main stream and nearly all tributaries. Regulation. — Flow partly regulated by the diversion dam at station and by storage in Nelson reservoir. Accuracy. — Stage-discharge relation not permanent; seriously affected by ice and by shifting control. Daily gage heights are mean of two readings daily to nearest tenth. Readings on the gage are difficult to make when gates are open and when flow over crest is large; this condition may introduce errors. An automatic crest on the dam keeps the water level above the dam fairly constant. It takes an appreciable change in water surface above the dam to overcome the inertia in these gates and so raise or lower them. As a result at low stages they tend to remain fixed and so give a fairly constant discharge below. Gage heights subject to error at medium and high stages when flow over crest of dam or through sluice gates causes wave action on gage.

Note. — Means for periods less than a full month but exceeding 15 days were considered means for the month in finding average and median flow. The median flow given was obtained by arranging the monthly means in their order of magnitude and taking the middle mean, or, if their nurhber was even, the average of the two middle means. By using daily discharge a considerably lower median discharge would bo obtained. The total yearly flow in acre-feet has been averagedj because in general the period of record covers the open-water season, and the flow during months for wluch records are missing was usually small. STATIONS ON TRIBUTARIES. NORTH FORK OF MILK RIVER NEAR BROWNING, MONT. Location. — In sec. 16, T. 37 N., R. 11 W., at Alexander Dubray's ranch, 35 miles north of Browning and about 2 miles south of the Canadian boundary line, on the Blackfeet Indian Reservation in Teton County. Records available. — May 8, 1911, to July 6, 1912. * Drainage area. — Not measured. Gage. — Staff gage nailed to a post on right bank. Channel and control. — Bed of steam composed of small gravel. Controlis a wide gravel bar, and is likely to sliift at medium and high stages. Banks low; subject to overflow during floods. DiscHARdE MKAsuuKMiONTrt. — JVIado by wading at convoiiicMt socliouH near the gage. Ice. — .Stream freezes over during the winter; winter gage heights have no value. 236 WATER SUPPLY OF ST. MARY AND MILK RIVERS, 1896-1917. • Accuracy. — Stage-discharge relation not permanent. Discharge measurements cover only a small range in stage . Hydrographic comparison with records obtained at the Canadian station at Peter's ranch for 1911 and 1912 indicates (1) that the observer at Dubray's ranch, reading to tenths only, does not record small changes in stage, (2) that the flow at Dubray's ranch is consistently lower than at Peter's ranch by a considerable amount, and (3) that the records for August and September, 1911, are of doubtful accuracy, owing to questionable gage readings.

(See PI. XXI.) Drainage area. — 101 square miles (measured on topographic maps). Records available. — July 21, 1909, to December 31, 1917. From July 21, 1909, to December 31, 1912, the station was about 2 miles farther downstream, in the NE. \ sec. 13, T. 1, R. 23 W. fourth meridian, and was maintained by the Recla- mation Service, Department of the Interior, . Canada. Gage. — Stevens water-stage recorder on left bank, 1913-1917; vertical staff used 1909 to 1912 and for winter readings to 1916; chain gage installed in September, 1916, was used for winter readings and as a check on water-stage recorder. Observer, Charles Barnett. Discharge measurements. — Made by wading, from footbridge 700 feet below gage, or from cable 800 feet below gage. Channel and control. — Bed of stream at gage and principal control formed of clay and small boulders; slightly shifting. Banks low and subject to overflow at flood stages. Control likely to shift during high water. Extremes of discharge.— 1909-1917: Maximum stage recorded, 4.86 feet June 23, 1911 (discharge, 555 second-feet); a stage of 3.9 feet July 27, 28, 1909, gave a discharge of 591 second-feet; minimum stage recorded, 1.97 feet December 7, 1915; minimum discharge recorded, 5 second-feet February 12, 1916 (stage, 3.45 feet). Ice. — Stage-discharge relation affected by ice. Diversions. — None. Regulation. — During July, August, and September, 1917, the flow was verj'- largely regulated by the quantity of water turned into this stream from the United States Reclamation Service St. Mary canal. This condition mil continue, as it is expected that the canal will be permanently in use. Accuracy. — Stage-discharge relation fairly permanent up to 191G; during 1916 and 1917 changed during high stages and by water from the United States Reclamation Service St. Mary canal. Open-water discharge computed by applying mean daily gage height to rating table and applying corrections for periods of shifting control; winter discharge determined from hydrographs based on discharge meas- urements, records of maximum and minimum temperature, and gage-lieight graphs. Records fair. CooPEiiATiON. — Station maintained jointly by the United States Geological Survey and the Reclamation Ser\'ice, Department of the Interior, Canada. » station formerly called "North Fork of Milk Rivor r\mr Kimball, Alta.," in reports published by the United States Government and "North Branch of Milk River at Peters' ranch" in Canadian reports. 238 ^ATER SUPPLY OF ST.

Diversions. — There are several diversions for irrigation below this station. Accuracy. — Stage-discharge relation not permanent in 1915. Gage read once daily to hundredths. Two rating curves made because of shifting control, but 14 measurements were made and rating curves are well defined between gage heights 1.60 feet and 2 feet. Daily discharge determined directly from curves. Records for period good. Discharge measurements of Deer Creek at Dickinson' s ranch, Alta., 1911-1916. Date. 1911.

MARY AND MILK RIVERS, 18£>8-1917. LODGE CREEK NEAR CHINOOK, MONT. Location. — In sec. 26, T. 33 N., R. 19 E., at highway bridge half a mile east of Chinook, Mont., in Blaine County. July 1, 1907, to April 16, 1908, station was in sec. 15 or 16, T. 33 N., R. 19 E., at the Rainholt ranch, 2 miles upstream. (See PI. XXI.) Drainage area, — Not measured. Records available. — April 9, 1906, to June 30, 1908. Gage. — ^The original gage was an inclined staff 170 feet above the bridge. An exten- sion consisting of a vertical rod reading from 14 to 19 feet was installed April 25, 1906. On June 27, 1906, a chain gage was installed on the upstream side of the highway bridge. On July 1, 1907, a new gage was installed at the Rainholt ranch of the Empire Cattle Co., 2 miles upstream; this gage was used July 1, 1907^ to April 16, 1908, when readings were resumed at the highway bridge. Discharge measurements. — Made from highway bridge or by wading. Channel and control. — Bed composed of gravel and mud; likely to shift. Back- water from Milk River affected stage-discharge relation during floods on Milk River. Ice. — Stream freezes over during winter months but there is practically no flow. Diversions. — West Fork ditch diverts about 4 miles north of Chinook. The first diversion was made in 1898. There are also other small diversions both in Canada and the United States. Water from Fort Belknap canal is at times wasted into the creek below the Rainholt ranch but above the highway bridge. Regulation. — None. Accuracy. — Stage-discharge relation not permanent; affected by backwater at high stages in Milk River. Records fair. Discharge measurements of Lodge Creek, near Chinooh, Mont., 1906-1908.

Drainage area. — 589 square miles. Records available. — Open- water period; incomplete records for 1912; complete records for 1913-1917. For incomplete records for 1909-10 and complete records for 1911-12, see records for "Frenchman River at Enriglit and Strong's ranch" at Eastend, 10 miles below this station. No tributaries enter between these two stations. Gage. — Vertical staff; read by A. T. Phillips. On August 24, 1917, because of diversion of channel by Canadian Pacific Railway Co., a temporary staff was placed in the new diversion channel about 400 feet north of site of old gage. Discharge mkasurements. — Made from a cable 900 feet below gage during flood stages and at gage during low stages by wading. Channel and control. — Bed of channel clay and gravel; fairly permanent. Banks covered with brush, subject to overflow in flood stages. An artilicial ci>ntrol that was placed in the cliannel in October, 1914, was damaged during Iho spring floixl of 191 G and repaired in October of the same year, but was totally destroyed in spring flood of 1917. Extremes of stage. — 1912-1917: Maximum stage recorded, 8.74 feet April 22, 1917 (discharge, 4,041 second-feet); minimum stage recorded, 0.89 foot August 0, 1914 (discharge, 1.50 second-feet). 346 WATER SUPPLY OF ST. MARY AND MILK RIVERS, 18&8-1&17. Ice. — Observations discontinued during winter months, although there is a small flow under the ice. Stage-discharge relation affected by ice during spring break-up. Diversions. — Several small irrigation projects divert water from this stream and its tributaries above this station. Accuracy. — Stage-discharge relation fairly permanent from 1912 to 1914 when arti- ficial control was constructed which gave permanent stage-discharge relation until washed out in spring flood of 1917.

Extremes op discharge. — Maximum stage recorded during period, 10.35 feet April 4, 1915 (discharge measured 2,750 second-feet); minimum stage recorded, 1.03 feet (discharge, 0,1 second-foot) September 6 to 9, 1910. (Seehydrograph, PI. XXV.) Ice. — Station not maintained during winter. Diversions. — A number of authorized projects divert water for irrigation above this station. A small quantity of return flow finds its way to river channel above gage. Amount of water diverted by Enright & Strong's ditch, above the station, is added to the flow in the river to obtain daily discharge. Accuracy. — Stage-discharge relation practically permanent except during spring break-up, when it is affected by ice. Gage read daily to hundredths. Dis- charge for early spring estimated from discharge measurements; discharge for other periods obtained by applying daily gage heights to rating table. Gage- height observations in the years 1911, 1912, 1913, 1914, and 1916 unreliable; record of daily discharge for these years roughly approximate ; other records fair.

Drainage area. — 1,826 square miles. Records available.- — Two discharge measurements only in 1915; complete records from May 14 to October 31, 1916. Open-water flow at Buzzard's ranch (p. 363), March 27, 1914, to October 25, 1915. Gage. — Vertical staff on right bank just above trail crossing. Discharge measurements. — Made by wading at crossing below gage or from cable at Buzzard's ranch at high stages. Channel AND control. — Bed, gravel; clean. Banks high, wooded, and steep; right bank subject to overflow. One channel at all stages. Control shifts at high stages. Extremes of discharge. — During 1916 maximum discharge was 5^223 second-feet March 30, 1916; minimum stage, 1.00 foot on September 22 and October 15, 1915. (discharge, 26 second-feet). (See hydrograph PI. XXV^I.) Ice. — Station not maintained during winter. Diversions. — Numerous diversions for irrigation above station. Accuracy.— Stage-discharge relation practically permanent except during periods of spring break up and flood stages. Gage read to hundredths daily. Deter- minations of daily discharge during spring break up in 1916 based on discharge measurements and observations of flow taken at Buzzard's ranch (p. 363); daily discharge for other periods obtained by appl>T.ng daily gage height to rating tab le . Records fair . This station was established on September 22, 1915, to take the place of the station at Buzzard's ranch, where an observer could not be obtained. During the spring break up in 1916 the engineer made discharge measurements and observations at Buzzard's ranch because there is no cable at Martin's. The flow at this station was determined by adding the flow of Littlebreed Creek and an allowance for local run-off to the flow at Buzzard's ranch.

Records available. — Open-water flow June 12, 1909, to November 15, 1912, and discharge measurements April, May, and June, 1913, when station was abandoned on account of the difficulty of obtaining a reliable observer. Gage. — Vertical staff; read by G. C. Garrison. Discharge measurements. — Made by wading. Measurements can not be made at extreme flood stage, as wading is impossible. Channel and control. — Bed composed of sand and coarse gravel. Both banks fairly high but are overflowed at extreme flood stages. Extremes op discharge. — Maximum stage recorded, 6.06 feet April 6, 1912 (dis- charge, 270 second-feet, estimated); minimum stage recorded, 1.55 feet June 7 to 10, 1912 (discharge 0.10 second-foot). Accuracy. — Stage-discharge relation permanent during low and ordinary stages. Owing to lack of high water measurements, records poor.

J sec. 30, T. 28 N., II. 33 E., on highway bridge at Hales crosediig, at site of proposed reservoir of United States lleclamatiou Service, 28 miles southeast of Malta, iii Phillips County. Drainage area. — Not measured. Records available. — March 31 to December 31, 1917. Gage. — Chain gage on downstream handrail of highway bridge. Discharge measurements. — Made from highway bridge or by wading at old ford crossing, 500 feet above bridge. 442 WATER SUPPLY OF ST. MARY AND MILK RIVERS, 1898-1917. Channel and control. — Channel is straight for 150 feet above and 200 feet below gage. Banks are high and practically without A'egetation. Left bank is over- flowed at gage height 18.5 feet. The low- water control is gravel and cobblestone bar 400 feet below gage; probably shifting. At stages above gage height 12.5 feet the river cuts across the first oxbow loop below and has a decided increase of slope, materially increasing the discharge. Point of zero flow about 0.10 foot. Extremes of discharge. — 1917: Maximum stage recorded, 19.5 feet, April 6, 1917 (discharge, 4,990 second-feet); minimum stage, 0.0 foot, pool stage; no flow. Ice. — Creek practically freezes solid during winter and ice jams are frequent during the spring break-up. No records obtained for this period. Diversions. — No diversions from main stream; several on small tributaries above. Regulation. — None. Accuracy. — Stage- discharge relation was permanent during 1917; rating curve . developed by 7 measurements made in 1916, 1917, and 1918; well defined, between 10 and 3,000 second-feet.

Location. — In sec. 35, T. 31 N., R. 32 E., at Craig's ranch, 3 miles south of Ashfield, near Sacho, the 'nearest post office, and about 18 miles from Malta in Phillips County. Records available.— July 5, 1903, to November 13, 1912. Drainage area. — Not measured. Gage. — Overhanging chain. The gage was first est^/blished at bridge" No. 455 of the Great Northern Railway, half a mile west of Ashfield; it was moved to its j)resent location, 2 J miles farther upstream, December 31, 1903. Channel. — The stream has a narrow vdnding channel cut about 20 feet deep into the gently sloping prairie. At flood stages the water overflows the banks and spreads out for considerable distance on each side. The channel carries little water except at the times of the spring floods or heavy rains, and during the summer months it is obstructed by a dense growth of weeds and willows, which have to be cleared out occasionally. At medium and high stages a second channel, known as Beaver Creek overflov^, receives the stream above the station, fills a depression to the west of the main channel, and reenters at a point some distance below the gage. Discharge measurements. — Made from a cable or by wading. Ice. — Ice present during the winter months, but there is practically no flow. Diversions. — Water is diverted from Beaver Creek by small ditches and by pumping plants. Accuracy. — Stage-discharge relation not permanent. The primary control of sand and gravel changes, and shifts are also caused by the growth of grass, weeds, and wil- lows along the banks. Records are poor.

Channel. — Bed of stream is sand and gravel and in summer is covered with grass and weeds. Water flows in this channel only when Beaver Creek is high; during the remainder of the season the water stands in pools and fluctuations in water level are due wholly to local rains and to evaporation. Discharge measurements. — At flood stages made at a bridge half a mile below the gage; low- water measurements are made by wading near the gage. • Accuracy. — Stage-discharge relation not permanent, owing to growth of vegetation. Discharge is flood flow of Beaver Creek and so fluctuates rapidly. Records poor. Discharge measurements of Beaver Creek overflow near Bowdoin, Mont., 1903-1906 and 1909-1912.

June 8-10 and 30, 1906, the discharge was probably in excess of 2,000 second-feet. No estimates of discharge could be made for 1911 on account of lack of currant-meter measurements.

The mean monthly flow for March, 1910, was obtained mostly from estimates of flow Mar. 5-12, 1910, based on high-water marks and statements by the observer. The accuracy is doubtful, but the flow was undoubtedly small. No estimates were made for 1911.

ROCK CREEK NEAR HINSDALE, MONT. Location. — In sec. 10, T. 31 N., R. 36 E., at Ottenstror's ranch, about 2 miles below- head gates of Rock Creek canal, and 6 miles northeast of Hinsdale, in Valley County. Drainage area. — Not measured. Records available. — April 19, 1912, to December 31, 1917. From July 5, 1905, to December 31, 1907, data were obtained at a station 2 miles upstream, just below diversion dam of Rock Creek canal. Flow at these two points is practically the same. Gage. — Combined overhanging chain and staS gage on the left bank back of John Ottenstror's house. Chain gage reads to 16.0 feet and staff 16.0to 24 feet. Original chain gage washed out during spring flood of 1917, and new one installed 30 feet above old site is now in use. Discharge measurements. — ^^lade by wading one-fourth mile below the gage at low and medium stages, and from a bridge 2 miles below at high stages. Channel and control. — The -water at the gage is deep and sluggish at low stages. The control is a gravel bar one-fourth mile below. Under natural conditions it shifts a little during high water. The left bank is high and does not overflow at the gage. The right bank is fairly high, but overflows at flood stages. Extremes of discharge. — Maximum stage recorded, 18.40 feet June 9, 1906, deter- mined bj' leveling from flood marks (approximate discharge determined from extension of rating curve, 6,220 second-feet); minimum stage recorded, no flow April 14 to May 2, May 9-24, and after July 12, 1906; after September 28, 1907; April 23-25, 27, 28, 30, May 1, 2, 4, 1913; May, 3, 5, 8, 10, 13, 1915; after September 13,1917. Ice. — Stage-discharge relation seriously affected by ice. Observations discontinued during winter months. Diversions. — There is no storage, but the normal summer flow is diverted above the gage during the irrigation season. Regulation. — None, Accuracy. — Stage-discharge relation likely to change during floods but permanent at low stages. A beaver dam on the control affected the stage discharge relation from August 10, 1915, to the time of the spring flood in 1916. The gage readings at this station have been good. Records good. 456 WATER SUPPLY OF ST. MAEY AI^D MILK RIVEESyt 1898-1917. Discharge measurements of Rock Creeh near Hinsdale, Mont., 1906-7 and 1912-1917. Made by — Gage height. Dis-, charge.

I sec. 31, T. 28 N., R. 42 E., 500 feet above the ford, one-fourth mile above the highway bridge three-eighths of a mile north of Nashua in Valley County. Drainage area. — Not measured. Records available. — July 11, 1908, to December 31, 1917. Gage. — Vertical staff in three sections nailed to trees on the left bank, one-fourth mile above highway bridge. It is read to tenths twice a day during fluctuating stage and once at other times. Discharge measurements. — Made by wading near gage or from a bridge one-fourth mile below. Control. — Bed of the stream is of mud. A slight gravel bar forms the control at low stages but is soon drowned out as the creek rises, and the control is the whole channel below the gage. Extremes op discharge. — Maximum stage recorded, 18.0 feet, April 11, 1916, deter- mined by leveling from flood marks (discharge, determined from extension of rating curve, about 2,700 second-feet); minimum stage recorded dry August 18 to September 4, 1909; May 27 to June 7; July 12-29, 1910; June 21 to September 5, 1911; August 1-31, 1913; August 19, 1916; July 12 to September 30, 1917. Ice. — ^During winter months discharge very small and observations are discontinued. Stage-discharge relation seriously affected by ice. Diversions. — No diversions during the period covered by this report. A United States Reclamation Service canal is practically completed, which will divert the entire flow during the irrigation season. Regulation.— A United States Reclamation Service reservoir on the middle fork of the stream will partially regulate flood flow. No storage to December 31, 1917. Accuracy. — Stage-discharge relation not permanent. Control affected by growth of vegetation and by leaves in the fall. At high stages the control may shift. At low stages changes are slow and covered by discharge measurements. Gage- height readings are fair. Records are fair. WATER SUPPLY OF ST.

Note. — Means for periods less than a full month but exceeding 15 days were considered means for the month in finding average and median flow. The median flow given was obtained by arranging the monthly means in their order of magnitude and taking the middle mean, or, if their number was even, the average of the two middle means. By using daily discharge a somewhat lower median discharge would be obtained. STATIONS ON CANALS. FORT BELKFAP CANAL NEAR CHINOOK, MONT. Location. — In SE. | sec. 20, T. 33 N., E. 18 E., at the highway bridge half a mile below head gates of canal on Milk River, 8 miles west of Chinook, in Blaine County, Records available. — -June 21, 1903, to December 31, 1917. Gages. — -Vertical staff on downstream side of first bent of piles from left bank. Prom 1903 to 1910 gage located at highway bridge one-fourth mile below. Both gage and bridge washed out by high water of June, 1908, and new gage installed June 27, 1908, at different datum within a few feet of old site. Datum raised 0.62 foot May 3, 1917. Discharge measurements. — Made from bridge or by wading below gage. Channel and control.— A check weir half a mile below the gage causes backwater at gage. Aquatic plants that grow in canal reduce velocity considerably in last part of irrigation season. Extremes of discharge. — Maximum discharge recorded 237 second-feet on May 31, 1906. Regulation. — Flow controlled by head gates. Accuracy. — Stage-discharge relation not permanent. Numerous discharge measure- ments and records of changes in check weir necessary to define changes in rating. Records fair. 476 WATEK SUPPLY OF ST. MAPtY AND MILK EIVEES, 1898-1917.

Records available. — April 22, 1906, to June 20, 1908. Canal not used in 1907. Gage. — A vertical staff fastened to a post in the bed of the canal just downstream from a highway bridge crossing the canal. Discharge measurements.^ — Made by wading a short distance above the gage. Channel and control. — The canal bed below the gage forme the control. It is composed of mud, and changes in the control are caused by the deposition of silt and the growth of weeds. There are no checks in the canal for several milee below the gage. Regulation. — The flow of the canal is regulated by head gates. Accuracy. — Stage-discharge relation not permanent. The gage-height record for 1906 and 1908 good up to June 10, 1908.

Discharge measurements. — Made by wading. Channel and control, — Bed of canal is earth; silt is deposited during the irrigation season. Weeds grow in the bottom of the canal during the summer months. A large slough into which the canal flows a few hundred feet below the gage may affect results, the height of the water in slough possibly affecting the slope of the water surface at the gage. Extremes op discharge. — Maximum discharge recorded, 32 second-feet June 27, 1911. Accuracy. — Control affected by deposition of silt and growth of vegetal iiuiltor in the canal.

Original estimates of daily discharge for 1996 were lost, and those given were computed from the published gage heights and monthly discharge. 1910: The diversion dam was destroyed by the high water in the spring of 1910 and no water was diverted that year. 1911: Head gates opened Apr. 22 and closed Aug. 14. 1912: Gates opened July 2 and closed Aug. 22. No flow July 5-8, 1912, on account of damage to crest of diversion dam caused by high water. 1913: Apr. 6 to May 15 the head gates were closed, but a small amount of water leaked through, estimated for the period Apr. 6-20 at 0.1 second-foot. May 16-31, the water came from waste water of Cook canal. May 16-^18 and 22-31 this was estimated at 0.1 second-foot. The head gates were opened May 31 and closed Aug. 25. A small amount of water leaked through the head gates after this date. 1914: Canal was practically dry after July 11. 1915: Water turned into canal Apr. 26; mean discharge estimated at one-half the measured discharge for that date. 1916: No flow before Apr. 26 nor after July 31. 1917: "Water standing in pools June 5-15, 17-21, Sept. 22-25 and 29-30.

Location.— In SW. i sec. 33, T. 33 N., R. 21 E., about 500 feet below head gates on Milk River, and 1^ miles southeast of Zurich, in Blaine County. Records available. — June, 1903, to December 31, 1917. Gage. — Vertical staff on right bank, 500 feet below head gates. Discharge measurements. — Made by wading 10 feet above gage. Channel and control. — Bed of canal is earth; no definite control. Check weirs several miles below gage may cause some backwater at high stages. Aquatic plants growing in canal during the irrigating season and the large amount of silt deposited also cause backwater. Accuracy. — Stage-discharge relation not permanent. Sufficient discharge measure- menta are necessary each year to define changes in the rating due to growth of vegetation and deposition of silt. Daily gage heights are mean of two readings daily.

WATER SUPPLY OF ST. MARY AI^TD MILK RIVERS, 1898-1917. 501 AGENCY DITCH NEAR HARLEM, MONT. Location.— In NW. i SW. i sec. 33, T. 32 N., R. 23 E., at spillway about 1,000 feet below highway bridge, half a mile below head gate on Milk River, and 4 miles south of Harlem, in Blaine County. (See PI. XXIV, B.) Records available. — July 14, 1905, to December 31, 1917. Gage. — Vertical staff, enameled face, on right-hand downstream post of check weir at spillway. Discharge measurements. — Made from bridge. Channel and control. — Bed of canal is earth; backwater is caused by aquatic plants growing in canal during operating season, and also by a check gate 1 mile below station. The amount of backwater caused by the check varies with the quantity of water diverted. Extremes of discharge, — Maximum discharge recorded, 128 second-feet May 28, 1916. Accuracy. — Control shifting. Numerous discharge measurements are necessary each year to define the rating curves. The shifts are also partly determined from notes by the observer concerning changes in the check gates. Records fair. The .canal takes water from Milk River for the irrigation of lands on the Fort Bel- knap Indian Reservation. This canal has been given a jjrior right by a decree of the United States Supreme Court to 125 second-feet of the water of Milk River and tribu- taries above the point of diversion.

Some idea of the discharge can be obtained by comparing the gage-height records with the discharge measurements made in these years. 1910: Flow estimates from discharge measurements and the following statement supplied by the irrigation engineer in charge: "Canal was opened Ai)r. 8 and remained constant until May 10, when it was shut down for repairs. Water turned into ditch June 2 and was constant until Juno 9, when gates were jiartly closed. June 10-14, discharge estimated. Gates opened June 15; same discharge as before being closed. June 22, gates raised, also flashboards on waste gate. After June 30 discharge decreased on account ol river falling. Gates closed July 27." 1911: Head gates opened Mar. 26 and closed for the season Julv 19. Discharge July 20-31 was lenkaso through the head gates; estimated at 1 second-foot. Estimate of discharge Mar. 26 to Apr. 25, originally published, has been omitted from compilation because of inade(iuate base data, 1912: Water turned into canal May 25, but no gage-height observations wore made until July 1.

Location.— In SW. i sec. 36, T. 1, R. 12 W. fourth meridian. Records available. — Incomplete records April 1, 1912, to November 23, 1912; two measui'ements only during October in 1914; complete records, 1915. Gage. — Vertical staff; read by F. W. Webster. Discharge measurements. — Made by wading or with a weir. Channel and control. — Original bed of ditch clay, but now overwashed with sand from Deer Creek, causing continual change in cross section. The banks are not subject to overflow, the surplus water finding its way through the two spillways at dam. Shifting control. Accuracy. — Stage-discharge relation very changeable. Gage read once daily to hundredths. Rating curves are fairly well defined. Records considered fan. The Deer Creek Cattle Co. diverts all the water from Deer Creek through theii* two ditches except during flood stages. No records obtained during 1917, although it is understood water was diverted and used. Discharge measurements of Deer Creeh Cattle Co.'s east ditch near St. Kilda, Alta., 1912, 1914, and 1915. Date.

Records available. — April 9 to August 9, 1905. Gage. — Vertical staff nailed to a post driven into the bottom of the canal, about a mile below the head gates. Discharge 'measurements, — Made by wading. Channel and control. — The ditch is built in a mud soil. The control is the bed of the ditch for some distance below the gage and is affected by growth of grass and weeds. Extremes of discharge. — Maximum discharge recorded, 8 second-feet July 14, 1905. Regulation. — Flow of eanal is controlled by head gates. Accuracy. — Stage-discharge relation not permanent. Station visited by engineers five times in 1905, but only two discharge measurements obtained. Discharge estimated April 9 to June 15. Sufficient data not available to compute daily discharge. The results at this station are poor on account of the fragmentary character of the records. All available data are published, however, as they give some idea of the flow of this canal.

The gage was read by Mr. Reser, and statements by him were probably used in making- the origninal estimates. The estimates are liable to a large percentage of error, but give some idea of the water diverted by the ditch. The following gage heights were reported in 1906, m feet: Apr. 28, 2.08; May 27 to June 6, 3.00, 3.00, 3.25, 3.00, 3.00, 2.07, 2.05, 2.08, 2.07, 2.03, 3.00. The dam was washed out by the flood in June, 1906, and the ditch was closed for the remainder of the season. WEST FORK DITCH NEAR CHmOOK, MONT.

Gage. — Vertical staff nailed to post in bed of ditch 200 feet below head gates. Discharge measurements. — Made by wading. Channel and control. — Control consists of bed of canal below gage. Shifts in control are caused by the growth of vegetal matter on the bottom and sides of the canal. WATER SUPPLY OF ST.

A discharge measurement on May 29, 1906, at gage height 3.66 showed a flow of 20 second-feet. Regulation. — Flow of canal is controlled by head gates. Accuracy. — Stage-discharge relation not permanent. A few scattering gage heights only are available, and the daily discharge is estimated from these and the dis- charge measurements. Records, therefore, poor. All available data are pub- lished, however, as they give some idea of the flow of the canal. • Discharge measurements of West Fork ditch near Chinook ^ Mont., 1905-6. Date.

COOK CANAL NEAR CHINOOK, MONT. Location. — In N. ^ sec. 30, T. 33 N., R. 20 E., half a mile below head gate on Battle Creek and 3 miles east of Chinook, in Blaine County. Records Available. — April 10, 1905, to Decem^ber 31, 1917. Gage. — Vertical staff on left bank 1,000 feet above point at which canal turns west and runs parallel with the road. Discharge measurements. — Made by wading where canal passes under the Great Northern Railway, half mile below gage. Channel and control. — Channel of earth. No well-defined control. Weeds grow- ing along the bottom cause backwater. Canal infested with beavers, whose dams are likely to cause backwater. Extremes op discharge. — Maximum discharge recorded for irrigation, 71 second- feet April 17, 1914. Accuracy. — Stage- discharge relation not permanent; affected by vegetal growth to varying amounts each season. A number of discharge measurements are necessary each year to define the rating curves. Gage read to half-tenths daily. Records fair. Water is diverted from Battle Creek half a mile above gage, and is used to irrigate lands in Milk River valley on south side of river. Canal crosses Milk River in a flume. Water can be wasted into Milk River at this flume, which is about 2 milea below the gage. Little water is returned to the stream intentionally, but when too much water is turned in at the head gate the flume acts as throttle. 528 WATEE SUPPLY OF ST. MARY AND MILK RIVERS, 1898-1917.

Note. — In computing the average flow the canal was assumed dry when no discharge was recorded. Location. MATHESON CANAL NEAB CHINOOK, MONT. -In NW. i sec. 29, T. 33 N., R. 20 E., at the highway bridge over the head gate on Battle Creek, one-fourth mile north of the main road and 34 miles east of Chinook, in Blaine County. Records available. — April 10, 1905, to December 31, 1917. Gage. — Vertical staff nailed to a post on the right bank, about 10 feet below the head gate of the canal; read once a day. Discharge measurements. — Made by wading below gage. Channel and control. — The bed of the canal is mud; no definite point of control. Weeds grow in the bottom of the canal during the summer months. Extremes of discharge. — Maximum discharge recorded for irrigation use, 28 second-feet May 1, 1905. June 7-10, 1906, the canal was bank full, and the dis- charge was estimated at 28 second-feet. Regulation. — The flow is regulated by the head gate at the gage. It also depends on the state of repair of the diversion dam. Accuracy. — Stage-discharge relation not permanent, due to growth of vegetal matter in the canal. Numerous discharge measurements are necessary each season to define the rating curves. Records fair.

June 7-10, the canal was bank full, due to the flood in Battle Creek; discharge equal to the capacity of the canal was assumed. Apr. 1-5, daily discharge esti- mated. Apr. 8, no gage height reported and no discharge given in previous published report Discharge for this day estimated as hydrographer states in his report that there was a continuous flow from the be- ginning of "the season. 1907: Practically no flow at this station. (See footnote to discharge measurements.) 1908: Daily discharge obtained by direct comparison of discharge measurements and gage heights, and although the percentage of error may be high the results are probably fair. No discharge July 8-28, Aug. 7-15, and after Aug. 26. 1910: Head gates opened Apr. 18; daily discharge Apr. 18-30 estimated from known conditions of regu- lation. Canal dry beginning June 17. 1911: Apr. 1-22, total discharge estimated at 350 acre-feet by ditch rider. 1913: Head gates were opened Apr. 3, and the flow remained practically constant to Apr. 26, v/hen gage observations were begun; mean discharge Apr. 4-25 estimated at 8 second-feet. No water running in the canal after Aug. 7. 1914: Waterturnedintoditchabout Apr. 1, but did not have much head. Dischai'ge Apr. 1-11 estimated 4 second-feet. Canal dry beginning July 9. 1915: High water of Apr. 1-3 due to washing out of head gates; water not used for irrigation; discharge estimated from observer's notes. Canal dry Apr. 13 to May 1 and beginning Aug. 25. 1916: Dam washed out and partly replaced in April: washed out again in Jime and not replaced during balance of year. Canal dry Apr. 1 to May 31, June 7, 8, 17-19, July 10-26, and after Aug. 2. Water in canal represents overflow from Battle Creek through gates, as canal was not used for irrigation in 1916. 1917: Dam and head gates were badly damaged by floods during the spring, this damage accounting for the small quantity of water diverted in 1917.

FLOODS IN MILK RIVER BASIN. The two greatest floods during the period of record on Milk River occurred in 1906 and 1912. The following table gives the estimated maximum discharge at several points on the main stream and also for the larger tributaries: Maximum discharge, in second-feet, of streams in Milk River valley heloiv Havre, floods of June, 1906, and April, 1912.

If the high vrater on Rock Creek and Milk River occurred simultaneously both places v/ere affected by backwater and the result should be somewhat smaller. Discharge probably did not exceed amoiont given. / Includes overflow. g Estimate based on flood section and svu-face slope, using Kutter's formula; accuracy doubtful; results should be used only in connection with other data. Note. — The estimates of maximum discharge for the flood of June, 1906, outside of the stations on Milk River at Havre and Malta, are based largely on flood cross sections and surface slope and should not be used except in connection with other data. The published maximum discharge for Rock Creek during the flood of 1906 has been reduced from 18,000 second-feet to 6,220 second-feet, based on the application of the maximum gage height to an extension of the rating curve.
