HYDROLOGIC DATA OF THE DEERFIELD RIVER BASIN, MASSACHUSETTS By Bruce P. Hansen, Frederick B. Gay, and L. G. Toler INTRODUCTION The Deerfield River, a tributary to the Connecticut River, is located in northwestern Massachusetts and south-central Vermont. It has a drain¬ age basin area of 664 square miles, of which 348 square miles lies within Massachusetts. This report covers only that part within Massachusetts and includes all, or parts of, the towns of Ashfield, Bernards ton, Buckland, Charlemont, Colrain, Conway, Deerfield, Florida, Greenfield, Hawley, ffeath, Leyden, Monroe, Plainfield, Rowe, Savoy, and Shelburne. Hydrologic data collected during an investigation of the water resources of the Deerfield River basin are presented in tabular form. This investigation was conducted by the U.S. Geological Survey in cooper¬ ation with the Massachusetts Water Resources Commission. The data are released in order to make available to the public basic hydrologic and related information that will facilitate the planning of water-resources development and will complement an interpretative report of the area to be published at a later date. Data presented in this report include selected information on wells and test borings, seismic surveys, streamflow records, chemical analyses of surface and ground water and of rainfall, and suspended-sediment con¬ centrations of surface water (see Plate 1 for locations of all hydrologic- data collection sites). The authors wish to acknowledge the public officials, consulting firms, industrial concerns, well drillers, and individual homeowners who have given their time and information to this study. - 1 - DEFINITION OF TERMS Definition of terms related to streamflow, water quality, and other hydrologic data, as used in this report, are defined as follows: Color is expressed in units of the platinum-cohalt scale proposed by Hazen (1892, p. 427-428). A unit of color is produced by one milligram per liter of platinum in the form of the chloroplatinate ion. The extent to which water is colored by material in solution is reported as part of the water analysis because a significant color in water may indicate the presence of organic material that may have some bearing on the dissolved-solids content. Cubic feet per second per square mile is the average number of cubic feet of water flowing per second from each square mile of area drained, assuming that the runoff is distributed uniformly in time and area. Cubic foot per second (cfs) is the rate of discharge representing a volume of 1 cubic foot passing a given point during 1 second and is equivalent to 7*48 gallons per second, 448.8 gallons per minute, or 646,317 gallons per day. Discharge is the volume of water (ormore broadly, total fluids) that passes a given point within a given period of time. Mean discharge is the arithmetic average of individual daily mean discharges during a specific period. Instantaneous discharge is the discharge at a particular instant of time. If this discharge is reported instead of the daily mean, the heading of the discharge column in the tables is "Discharge (cfs)." Drainage area of a stream at a specified location is that area, measured in a horizontal plane, enclosed by a topographic divide from which direct surface runoff from precipitation normally drains by gravity into the stream above the specified point. Figures of drainage area given herein include all c losed basins , or noncontributing areas, within the area unless otherwise noted. Gage height is the water-surface elevation referred to some arbitrary gage datum. Gaging station is a particular site on a stream where systematic observations of gage height or discharge are obtained. When used in con¬ nection with a discharge record, the term is applied only to those gaging stations where a continuous record of discharge is obtained. Hardness of water is a physical-chemical characteristic attributable to the presence of alkaline earths (principally calcium and magnesium) and is expressed as equivalent calcium carbonate (CaC 03 ). - 2 - Micrograms per liter (yg/l, UG/l) is a more precise unit for expres¬ sing the concentration of chemical constituents in solution. One thousand micrograms per liter is equivalent to one milligram per liter. See below. Milligrams per liter (mg/l, MG/l) is a unit for expressing the con¬ centration of chemical constituents in solution. Milligrams per liter represents the weight of solute per unit volume of water. Milligrams or micrograms per liter may be converted to milliequivalents (one thousandth of a gram-equivalent weight of a constituent) per liter by multiplying by the factors in the table below. Concentration of suspended sediment expressed in milligrams per liter is based on the weight of sediment in a liter of water-sediment mixture. Ion Multiply Ion Multiply iy Aluminum (Al +3 )*. 0.11119 Lead (Fb + 2 )*.

Runoff in inches shows the depth to which the drainage area would be covered if all the runoff for a given time period were uniformly distrib¬ uted on it. Sediment is solid material that originates mostly from disintegrated rocks and is transported by, suspended in, or deposited from water; it includes chemical and biochemical precipitates and decomposed organic material such as humus. The quantity, characteristics, and cause of the occurrence of sediment in streams are influenced by environmental factors. Some major factors are degree of slope, length of slope, soil character¬ istics, land usage, and quantity and intensity of precipitation. Sediment discharge is the rate at which dry weight of sediment passes a section of a stream or is the quantity of sediment, as measured by dry weight, or by volume, that is discharged in a given time. Solute is any substance derived from the atmosphere, vegetation, soil, or rocks that is dissolved in water. - 3 - Specific conductance is a measure of the ability of a water to con¬ duct an electrical current and is expressed in micromhos per centimeter at 25°C. Because the specific conductance is related to the number and specific chemical types of ions in solution, it can be used for approxi¬ mating the dissolved-solids content in the water. Commonly, the amount of dissolved solids (in milligrams per liter) is about 65 percent of the specific conductance (in micromhos). This relation is not constant from stream to stream or from well to well, and it may even vary in the same source with changes in the composition of the water. Suspended sediment is the sediment that at any given time is main¬ tained in suspension by the upward components of turbulent currents or that exists in suspension as a colloid. Tons per day is the quantity of a substance in solution or suspension that passes a stream section during a 24-hour period. WSP is used as an abbreviation for "Water-Supply Paper" in references to previously published reports. NUMBERING AND LOCATION OF HYDROLOGIC-DATA COLLECTION SITES Surface-Water Stations Records are listed in a downstream direction along the main stream, and stations on tributaries are listed between stations on the main stream in the order in which those tributaries enter the main stream. Stations on tributaries entering above all mainstream stations are listed before the first mainstream station. Stations on tributaries to tributaries are listed in a similar manner. All stations are numbered consecutively in downstream order in this report. If a station has been assigned a number for the U.S. Geological Survey national surface-water data network, the network number is shown in parentheses. Ground-Water Sites The well-numbering system of the U.S. Geological Survey is based on the grid system of latitude and longitude. The number consists of 14 digits and 1 letter. The first 6 digits denote the degrees, minutes, and seconds of latitude followed by a letter denoting north or south. Seven digits following the letter denote degrees, minutes, and seconds of longitude. The last digit is a sequential number for wells within a one-second grid. The system provides the geographic location of the well and a unique number for each well. A local numbering system for wells and borings is also used in this report. The first two letters of the local well or boring number are town code letters, e.g. GR for Greenfield; the third letter indicates whether the hole is a well (w), auger boring (A), bridge boring (B), or roadway boring (R); and the number indicates the order in which the well or boring - 4 - was inventoried within the town. A separate series of numbers beginning with "1" is used within each town. In tables, the complete local number is used; however, on the map (Plate l), only the number appear.s beside well locations, or the number plus "A", "B" or "R" for borings within the designating town boundaries. COLLECTION AND EXAMINATION OF HYDROLOGIC DATA Streamflow The base data collected at continuous-record gaging stations consist of records of stage and measurements of discharge. Records of stage are obtained from a graphic water-stage recorder that gives a continuous rec¬ ord of the fluctuations or from a digital recorder that punches tape at 15 -, 30-, or 60-minute intervals. Measurements of discharge are made with a current meter, using the general methods adopted by the Geological Survey on the basis of experience in stream gaging since 1888. These methods are described in standard textbooks on the measurement of stream discharge. (See also SELECTED REFERENCES.) More detailed information than that published for the gaging stations, such as discharge measurements, gage-height record, and rating tables, is on file in the district office. The long-term gaging-station records (through 1987) have been analyzed to give several statistical summaries, including (l) the number of days in each year that the daily discharge was between selected limits (duration tables); (2) the lowest mean discharge for selected numbers of consecutive days in each year; and (3) the highest mean discharge for selected numbers of consecutive days in each year. Measurements of streamflow made at low-flow discharge stations are made during periods of base flow when streamflow is primarily from ground- water storage. These measurements, when correlated with the simultaneous discharge of a nearby stream where continuous records are available, will give a picture of the low-flow potentiality of the stream. Solutes The methods of collecting and analyzing the water samples for deter¬ mining the kinds and concentrations of solutes are described by Brown and others (l970). One sample can define adequately the water quality at given time if the mixture of solutes throughout the stream cross section is homogeneous. However, the concentration of solutes at different lo¬ cations in the cross section may vary widely with different rates of water discharge, depending on the source of material and the turbulence and mixing of the stream. Some streams must be sampled at several verticals across the channel to determine accurately the solute load. Ground-water quality does not change significantly during short per¬ iods of time; infrequent sampling and analysis of ground water adequately define ground-water quality at a given site. Water samples from wells are analyzed individually. - 5 - Solids are dissolved from the atmosphere by precipitation. The amount and type of solids may be affected by the source of airborne par¬ ticles, the -wind direction and velocity, and the rainfall intensity and duration. Samples of rainfall -were collected monthly during selected periods. Temperature Most large streams have a small diurnal temperature change, while small, shallow streams may have a daily range of several degrees and may follow closely the changes in air temperature. Some streams may be af¬ fected by waste-heat discharges. To convert temperature data shown in degrees Celsius (centigrade, °C) to degrees Fahrenheit (°F), see following table: degrees °F Temperature conversion table, Celsius (°c) to degrees Fahrenheit ( = 9/5 (°C) +32 or °C = 5/9 (°F -32) 'F) °c °F °c °F °c °F °c °F 0.0 32 10.0 50 20.0 68 30.0 86 • 5 33 10.5 51 20.5 69 30.5 87 1.0 34 11.0 52 21.0 70 31.0 88 1.5 35 H.5 53 21.5 71 31.5 89 2.0 36 12.0 54 22.0 72 32.0 90 3.0 37 13-0 55 23.0 73 33.o 91 3-5 38 13-5 56 23.5 74 33.5 92 4.0 39 i4.o 57 24.0 75 34.0 93 4.5 40 14.5 58 24.5 76 3^-5 94 5-0 4l 15.0 59 25.0 77 35.0 95 5-5 42 15.5 60 25.5 78 35-5 96 6.0 43 16.0 61 26.0 79 36.0 97 6.5 44 16.5 62 26.5 80 36.5 98 7-0 ^5 17.0 63 27.0 81 37.0 99 8.0 46 18.0 64 28.0 82 38.0 100 8.5 4? 18.5 65 28.5 83 38.5 101 9.0 48 19.0 66 29.0 84 39.0 102 9.5 49 19.5 67 29.5 85 39.5 103 Sediment Suspended-sediment samples were collected periodically, particularly during periods of storm runoff when most of the suspended - sediment load is transported. Although data collected periodically may represent con¬ ditions only at the time of observations, such data are useful in estab¬ lishing seasonal relations between quality and streamflow in predicting long-term sediment-discharge characteristics of the stream. - 6 - SELECTED REFERENCES Brown, Eugene, Skougstad, M.W., and Fishman, M.J., 1970, Methods for col¬ lection and analysis of water samples for dissolved minerals and gases: U.S. Geol.
