SCOPE OP WORK

This volume is one of a series of 20 reports presenting records of stage, discharge, 

and content, of streams, lakes, and reservoirs In the United States during the 1959 water 

year. Since 1888, when the United States Geological Survey first studied streatnflow In 

relation to problems of Irrigation, similar records have been obtained at more than 15,200 

gaging stations in the 50 States. On September 30, 1959, the Geological Survey and cooperating organizations were maintaining 7,110 gaging stations. Partial-record stations for 

low flow or for flood flow have been operated at many other points. In addition discharge 

measurements are made at miscellaneous sites. The records for the 1959 water year at 

gaging stations, partial-record stations, and miscellaneous sites in the North Atlantic 

slope basins, Maine to Connecticut, are given in this report.

COOPERATION

Many State, municipal, and private organizations have cooperated with the Geological 

Survey in this work by either furnishing or helping to collect data. Organizations that 

supplied data are acknowledged in station descriptions', and organizations that assisted in 

the collection of data through cooperative agreements with the Survey are:

Information of a more detailed nature than that published for most of the gaging stations given in this report is on file in the district offices listed above. Some gaglngstation records for Massachusetts and Vermont have been analyzed by electronic computer to 

give: (1) 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. Provisional records of discharge, information on the availability of 

electronic computer results, and other unpublished data concerning the gaging-station records may generally be obtained from the district office.

DEFINITION OF TERMS AND ABBREVIATIONS

The terms of streamflow and other hydrologic data, as used in this report, are defined 

as follows:

Gaging station is a particular site on a stream, canal, lake, or reservoir where systematic observations of gage height or discharge are obtained. When used in connection with 

a discharge record, the term is applied herein only to those gaging stations where a continuous record of discharge is obtained.

Partial-record station is a particular site where limited streamflow data are collected 

systematically over a period of years for use in hydrologic analyses.

Cubic foot per second (cfs) is the rate of discharge of a stream whose channel is 

1 square foot in cross-sectional area and whose average velocity is 1 foot per second.

DOWNSTREAM ORDER AND STATION NUMBERS 3

Cubic feet per second per square mile (cfsm) 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.

Runoff in Inches (in.) shows the depth to which the drainage area would be covered if

all the runoff for a given time period were uniformly distributed on it.

Acre-foot (ac-ft) is the quantity of water required to cover an acre to the depth of 

1 foot and is equivalent to 43,560 cubic feet.

Cfs-day is the volume of water represented by a flow of 1 cubic foot per second for 

24 hours. It is equivalent to 86,400 cubic feet, 1.983471 acre-feet, or 646,317 gallons, 

and represents a runoff of 0.0372 inch from 1 square mile.

Stage-discharge relation is the relation between gage height and the amount of water 

flowing in a channel, expressed as volume per unit of time.

Control designates a feature downstream from the gage that determines the stage-discharge relation at the gage. This feature may be a natural constriction of the channel, a 

long reach of the channel, or an artificial structure.

Contents is the volume of water in a reservoir. Unless otherwise indicated, volume is 

computed on the basis of a level pool and does not include bank storage.

The drainage area of a stream at a specified location is that area, measured in a horizontal plane, which is so enclosed by a topographic divide that direct surface runoff from 

precipitation normally would drain by gravity into the river above the specified point. 

Figures of drainage area given herein include all closed basins, or noncontributing areas, 

within the area unless otherwise noted.

WSP is used as an abbreviation for "Water-Supply Paper" in references to previously 

published reports.

DOWNSTREAM ORDER AND STATION NUMBERS

Beginning with the series of reports for the water year ending September 30, 1951, the 

order of listing gaging-station records was changed. In this report, in a downstream 

direction along the main stem, all stations on a tributary entering above a main-stem station are listed before that station. If a tributary enters between two main-stem stations, 

it is listed between them. A similar order is followed in listing stations on first rank, 

second rank, and other ranks of tributaries. To indicate the rank of any tributary on 

which a gaging station is situated and the stream to which it is immediately tributary, 

each indention in the listing of gaging stations in the table of contents of this report 

represents one rank. This downstream order and system of indention show which gaging stations are on tributaries between any two stations on a main stem and the rank of the tributary on which each gaging station is situated.

The order of listing used before the publication of the 1951 report listed first all 

stations on the main stem from headwaters toward mouth, then all stations on the uppermost 

tributary to the main stem from the tributary's source to mouth, and then all stations 

from source to mouth of the uppermost tributary to the tributary.

As an added means of identification, each gaging station and partial-record station has 

been assigned a station number. The numbers have been assigned in the same downstream 

order used in this report. In assigning station numbers, no distinction is made between 

partial-record stations and regular gaging stations, so that the station number for a 

partial-record station indicates downstream-order position in a list made up of both types
4 SURFACE WATER SUPPLY, 1959, PART 1-A

of stations. Gaps are left in the numbers to allow for new stations that may be estab1'ished; hence the numbers are not consecutive. The complete number for each station includes the part number, but the station number as shown in this report, just to the left 

of the station name, consists of only the essential digits of the complete number. For example, for a station with the complete number 1A-0345.00 the station number shown in this 

report is 345. The notation to the left of the hyphen is the part number; it is 1A for all 

stations in this report and is therefore omitted.

EXPLANATION OF DATA

The base data collected at gaging stations consist of records of stage and measurements 

of discharge. In addition, observations of factors affecting the stage-discharge relation, 

weather records, and other information are used to supplement base data in determining the 

daily flow. The records of stage are obtained either from direct readings on a nonrecording gage or from a water-stage recorder that gives a continuous record of fluctuations. 

Measurements of discharge are made with a current meter by the general methods adopted by 

the Geological Survey on the basis of experience in stream gaging since 1888. These 

methods are described in Water-Supply Paper 888 and are also outlined in standard textbooks on the measurement of stream discharge.

Rating tables giving the discharge for any stage are prepared from stage-discharge relation curves defined by discharge measurements. If extensions to the rating curves are 

necessary to define the extremes of discharge. they are made on the basis of indirect 

measurements of peak discharge (such as slope-area or contracted-opening measurements, 

computation of flow over dams or weirs, and by other methods), velocity-area studies, and 

logarithmic plotting. The application of the daily mean gage height to those rating 

tables gives the daily mean discharge, from which the monthly and the yearly mean discharge are computed. If the stage-discharge relation is subject to change because of frequent or continual change in the physical features that form the control, the daily mean 

discharge is determined by the shifting-control method, in which correction factors based 

on individual discharge measurements and notes by engineers and observers are used in applying the gage heights to the rating tables. If the stage-discharge relation for a station is temporarily changed by the presence of aquatic growth or debris on the control, 

the daily mean discharge is computed by what is essentially the shifting-control method.

At some gaging stations the stage-discharge relation is affected by backwater from reservoirs, tributary streams, or other sources. This necessitates the use of the slope 

method in which the slope or fall in a reach of the stream is a factor in determining discharge. Information requisite for determining the slope or fall is obtained by means of 

an auxiliary gage set at some distance from the base gage. At some stations the stagedischarge relation is affected by changing stage. If so, the rate of change in stage is 

used as a factor in the determination of discharge.

At most gaging stations in the northern part of the United States and at some in the 

mountainous regions of other parts the stage-discharge relation is affected by ice during 

the winter, and it becomes impossible to compute the discharge in the usual manner. Discharge for periods of ice effect is computed on the basis of the gage-height record and 

occasional winter discharge measurements, consideration being given to the available information on temperature and precipitation, notes by gage observers and engineers, and 

comparable records of discharge for other stations in the same or nearby basins. If the 

stage-discharge relation is affected by ice, this information is given in a note to the
EXPLANATION OP DATA 5

table. No mention is made of occasional days of ice effect if the degree of accuracy of 

daily records is not changed.

The data herein presented generally comprise a description of the station, a skeleton 

rating table, and a table showing the daily discharge and monthly and yearly discharge of 

the stream. Records are published for the water year which begins on October 1 and ends on 

September 30. A calendar for the 1959 water year is shown on page IV for the purpose of 

finding the day of the week for any date.

The description of the station gives the location, drainage area, records available, 

type and history of gages, average discharge, extremes of discharge, general remarks, and 

notations of revisions of the previously published record. The location of the gaging 

station and the drainage area are obtained from the most accurate maps available. River 

mileage, given under "Location" for some stations, is that determined and used by the 

Corps of Engineers unless otherwise noted. Under "Records available" are given the 

periods for which there are published records generally equivalent to those at present 

site-. Under "Gage" are given the type of gage currently in use and the datum of the present gage above mean sea level, and a condensed history of the types, locations, and datums 

of previous gages used during the period of records available. Under "Average discharge" 

is given the average discharge for the number of years indicated. It is not given for 

stations having fewer than five complete years of record or for stations where changes in 

water development during the period of record cause the figure to have little significance. 

Under "Extremes" are given the maximum discharge and gage height; the minimum discharge if 

there is little or no regulation; the minimum daily discharge if there is extensive regulation (also the minimum discharge if useful); and the minimum gage height (unless it is 

of no importance). In the first paragraph, the data given are for the complete current 

water year unless otherwise specified. In the second paragraph, the data given are for 

the periods of record within the calendar year dates in the heading (not necessarily those 

for the complete years indicated by the heading dates). Reliable information concerning 

major floods that have occurred outside the period of record are given in the third or 

last paragraph under "Extremes." Unless otherwise qualified, the maximum discharge corresponds to the crest stage obtained by use of a water-stage recorder, a crest-stage indicator, or a nonrecording gage read at the time of the crest. If the maximum gage height did 

not occur at the same time as the maximum discharge, it is given separately. Information 

pertaining to the accuracy of the records and conditions which affect the natural flow at 

the gaging station is given under "Remarks."

Previously published records of some stations have been found to be in error on the 

basis of data or information later obtained. Revisions of such records are usually published along with the current records in one of the annual reports. In order to make it 

easier to find such revised records, a paragraph headed "Revisions (water years)" has been 

added to the description of all stations for which revised records have been published. 

Listed therein are all the reports in which revisions have been published, each followed 

by the water years for which figures are revised in that report. In .listing the water 

years only one number is given; for instance, 1933 stands for the water year October 1, 

1932, to September 30, 1933. If no daily, monthly, or annual figures of discharge are 

concerned in the revision, that fact is brought out by notations after the year dates as, 

follows: "(M)" means that only the instantaneous maximum discharge was revised; "(m)" 

that only the instantaneous minimum was revised; and "(P)" that only peak discharges were 

revised. If the drainage area has been revised, the report in which the revised figure
6 SURFACE WATER SUPPLY, 1959, PART 1-A

was first published is given. It should be noted that for all stations for which cubic 

feet per second per square mile and runoff in inches are published, a revision of the 

drainage area necessitates corresponding revision of all figures based on the drainage 

area. Revised figures of cubic feet per second per square mile and runoff in inches resulting from a revision of the drainage area only are usually not published in the annual 

series of reports.

Skeleton rating tables are published for all stations except tho'se at which the daily 

discharge for the greater part of the open-water period was determined by the shiftingcontrol method, the slope method, or other special methods involving an equivalent adjustment to the gage height of more than one-tenth foot. Skeleton rating tables are generally 

not published for stations on canals.

For stations equipped with water-stage recorders, except those on streams subject to 

sudden or rapid fluctuation, the daily table gives the discharge corresponding to the 

daily mean gage height. For stations subject to such fluctuation the daily mean gage 

height may not indicate the true daily mean discharge, which must be obtained by averaging 

the discharge for parts of the day or by using the discharge integrator, an instrument for 

obtaining the daily mean discharge from a continuous gage-height graph and containing, as 

an essential element, a curve representing the stage-discharge relation at the station. 

For stations equipped with nonrecording gages, the table of daily discharge gives the 

discharge corresponding to once-daily readings of the gage, or to the mean of twice-daily 

readings, or to the mean gage height determined from gage-height graphs based on gage 

readings. For periods of rapidly changing stage, the daily mean discharge is determined 

from gage-height graphs based on gage readings, the frequency of which is stated in the 

station description.

In the table of daily discharge, the figures for the maximum day and the minimum day 

for each month are underlined. If the figure is repeated, it is underlined only on the 

first day of its occurrence.

In the monthly summary below the daily table, the line headed "Total" gives the sum of 

the daily figures; it is the total cfs-days for the month. The line headed "Mean" gives 

the average flow in cubic feet per second during the month. Discharge for the month may 

be expressed in cubic feet per second per square mile (line headed "Cfsm"), or in inches 

(line headed "In."), or in acre-feet (line headed "Ac-ft"). Figures for cubic feet per 

second per square mile and runoff in inches are omitted if the drainage area includes 

large noncontributing areas, or if the average annual rainfall over the drainage basin is 

usually less than 20 inches.

In the yearly summary below the monthly summary, the figures of maximum are the maximum 

daily discharges, not the momentary discharges when the water was at crest stage. Likewise, the minimums in this summary are the minimum daily discharges.

Peak discharges and the times of their occurrence and corresponding gage heights of 

most stations are listed below the table of daily and monthly discharge. All independent 

peaks above the selected base are given. The base discharge, which is given in parentheses, is selected so that an average of about three peaks a year will be presented. 

Peak discharges are not published for canals, ditches, drains, or for any stream for which 

the peaks are subject to substantial control by man.

Footnotes to the table of daily discharge indicate periods when discharge was computed 

or estimated by unusual or special methods during periods of no gage-height record and ice 

effect, or by other effects that reduce the degree of accuracy of the records. Days on
ACCURACY OF FIELD DATA AND COMPUTED RESULTS 7

which discharge measurements were made are indicated by asterisk and footnote unless they 

were made at frequent regular intervals, in which instance the general frequency of 

discharge measurements is given under "Remarks" in the station description.

For most gaging stations on lakes and reservoirs the data presented comprise a description of the station and a monthly summary table of stage and contents. For some reservoirs a table showing daily contents or stage is given. A skeleton table of capacity at 

given stages is published each year for all reservoirs for which records are published on 

a daily basis, but is not published for reservoirs for which only monthly data are given.

At many gaging stations water samples are collected from the streams for the purpose of 

making chemical analyses, computing dissolved solids, suspended sediment loads, and 

particle-size distribution, or measuring water temperatures. For most of these samples 

the results are published in an annual series of water-supply papers entitled "Quality of 

Surface Waters of the United States" which is issued in four volumes. In this report 

under "Remarks" a reference is made to quality-of-water records collected at gaging stations on a regular basis and published in the quality-of-water reports. At many other 

gaging stations quality-of-water data are obtained at irregular intervals and published 

as "miscellaneous analyses" in quality-of-water reports; such records are not referred to 

in "Remarks" paragraph in this report. At many gaging stations water temperature is 

obtained also at the time a discharge measurement is made; such temperature readings are 

not reported in the quality-of-water annual reports.

Data collected at partial-record stations and at miscellaneous sites are given at the 

end of each report. Partial-record stations are presented in two tables. The first is a 

table of discharge measurements at low-flow partial-record stations, and the second is a 

table of annual maximum stage and discharge at crest-stage stations. Discharge measurements at miscellaneous sites are given in a third table. Occasionally, a series of discharge measurements are made within a short time period to investigate the seepage gains 

or losses along a reach of a stream or to determine the low-flow characteristics of an 

area. Such measurements are given in special tables after the list of measurements at 

miscellaneous sites.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of streamflow data depends primarily on (1) the stability of the stagedischarge relation or, if the control is unstable, the frequency of discharge measurements, 

and (2) the accuracy of observations of stage, measurements of discharge, and interpretation of records.

The station description states the degree of accuracy of the records. "Excellent" indicates that, in general, the error in the daily records is believed to be less than 5 percent; "good," less than 10 percent; "fair," less than 15 percent; and "poor," probably 

more than 15 percent. The records of monthly and yearly mean discharge and runoff are, in 

general, more nearly accurate than the daily records.

Discharge at some stations, as indicated by the monthly mean, may vary widely from natural runoff, owing to diversion, consumption, regulation by storage, increase or decrease 

in evaporation due to artificial causes, or to other factors. For such stations, figures 

of cubic feet per second per square mile and of runoff in inches are not published unless 

satisfactory adjustments can be made for diversions, for changes in contents of reservoirs, or for other changes incident to use and control. Evaporation from a reservoir is 

not included in the adjustments for changes in reservoir contents, unless it is so stated. 

Even at those stations where adjustments are made, large errors in computed runoff may
SURFACE WATER SUPPLY, 1959, PART 1-A

occur when relatively large negative adjustments are made or when evaporation Is large In 

comparison with the observed discharge.

Many gaging stations on streams In the Irrigated areas of the United States are situated 

above most or the diversions from those streams, and therefore the discharge recorded does 

not actually show the water supply available at the stations for further development, because water must first be supplied to existing Irrigation systems.

PUBLICATIONS

Basic data for gaging stations are published In an annual series of reports consisting 

of 20 volumes, Including one each for the States of Alaska and Hawaii. The area of the 

other 48 States Is divided Into 14 parts whose boundaries coincide with certain natural 

drainage lines. Formerly, the annual series of reports on surface water supply consisted 

of 14 volumes, one for each of the 14 parts. Beginning with the reports for 1951, the records for the 48 States were published In 18 volumes, there being 2 volumes each for Parts 1,

A compilation of records for the area covered by this report through September 1950 

has been published as Water-Supply Paper 1301. That report contains a summary of monthly 

and annual discharges for all previously published records as well as some records not 

contained In the annual series of water-supply papers. All records were reexamlned and 

revised where warranted. Estimates of discharge were made to fill short gaps whenever 

practical.

The reports listed In the foregoing tables contain the customary records of discharge 

collected during the systematic operation of gaging stations. Detailed Information on the 

stage and discharge of many streams during major floods has been Included In special reports on these floods published by the Geological Survey. The more recent of these 

special reports also contain other pertinent hydrologlc Information and analyses and compilations of data relating to earlier notable floods. The following list gives the numbers and titles of these reports:

staff gages at dam on outlet of Sebago Lake.

Average discharge. 72 years, 661 cfs (unadjusted).

Remarks. Discharge computed from Alien Meter records for each of three pairs of water 

wheels and from records of openings of two regulating gates at Eel Weir hydroelectric 

plant. Water wasted at rare intervals through gates in dam on outlet of Sebago Lake; 

flow computed from records of gate openings. Water diverted by Portland Water District 

and leakage through dam, totaling about 35 cfs, not included in figures of daily discharge. Plow completely regulated by Highland, Long, and Pleasant Lakes, Brandy, 

Thomas, and Panther Ponds, Sebago Lake (surface area, 45.6 sq mi), and by several 

smaller ponds, which have a combined usable capacity of 13,535,000,000 cu ft.

papers for 1930-58, may be subject to error because of uncertainty concerning proper 

adjustments.

Gage. Water-stage recorder and concrete control. Datum of gage is 20.63 ft above mean 

sea level, datum of 1929.

Average discharge. 29 years, 200 cfs (adjusted for diversions).

146 THAMES RIVER BASIN

1220. Natchaug River at Willimantlc, Conn.

Location. Lat 41°43'14", long 72"11'52", on right bank 200 ft downstream from New York, 

New Haven and Hartford Railroad bridge, 500 ft upstream from bridge on U. S. Highway 6, 

1 mile northeast of Willimantlc, Windham County, 1.7 miles upstream from mouth, and 

4 miles downstream from Mount Hope River.

Drainage area. 169 sq mi.

Records available.--October 1930 to September 1959.

Gage. Water-stage recorder. Datum of gage is 150.31 ft above mean sea level, datum of 

1929 (levels by Corps of Engineers).

Average discharge. 29 years, 302 cfs (adjusted for storage).

Extremes. Maximum discharge during year not determined; maximum daily, 2,300 cfs Apr. 7; 

minimum, 3.5 cfs Sept. 30 (gage height, 2.03 ft); minimum daily, 3.5 cfs Sept. 30.

1930-59: Maximum discharge, 32,000 cfs Sept.21, 1938 (gage height, 16.39 ft, from 

floodmarks), by computation of peak flow over dam 2 miles upstream; minimum, about 

0.3 cfs Aug. 6, 1937; minimum dally, 2.3 cfs Sept. 11, 12, 1943.

Remarks. Records good except those for periods of ice effect or no gage-height record, 

which are fair. City of Wlllimantic diverts an average of about 1,000,000 gal of water 

a day for municipal supply from reservoir 2 miles upstream. Operation of water wheels 

at this location causes diurnal fluctuation at low flow. Flow regulated since March 

1952 by Mansfield Hollow Reservoir (see p. 158).

THAMES RIVER BASIN 153

1255. Quinebaug River at Putnam, Conn.

Location. Lat 4I°54'34", long 71°54'48", on right bank at Putnam, Windham County,

0.15 mile downstream from Little River, 0.3 mile upstream from New York, New Haven and 

Hartford Railroad bridge, 2.8 miles downstream from French River, and at mile 35.7.

Drainage area. 331 sq mi.

Records available. December 1929 to September 1959. October and November 1929 monthly 

discharge only, published in WSP 1301.

Gage. Water-stage recorder. Datum of gage is 216.76 ft above mean sea level, datum of

1929. Prior to Aug. 1, 1958, at same site on left bank at same datum.

Average discharge. 30 years, 571 cfs.

Extremes. Maximum discharge during year, 5,510 cfs Apr. 3 (gage height, 10.06 ft); minimum, 32 cfs Sept. 21 (gage height, 1.87 ft); minimum daily, 40 cfs Aug. 22.

1929-59: Maximum discharge, 48,000 cfs Aug. 19, 1955 (gage height, 26.5 ft, from 

floodmarks), from rating curve extended above 2,500 cfs on basis of computation of flow 

over dam at gage heights 17.28 and 19.45 ft and slope-area measurement of peak flow; 

minimum, 8.0 cfs Aug. 9, 1953 (gage height, 1.54 ft); minimum daily, 11 cfs Oct. 5, 12,

1930.

Remarks. Records excellent except those for Dec. 10-30, which are good, and those for 

AugT 3-26, which are fair. City of Putnam diverts an average of less than 1 mgd from 

Little River for municipal supply. Large diurnal fluctuations, particularly during low 

flow, caused by many dams and reservoirs upstream, largest of which is Lake Chaubunagungamaug with an estimated usable capacity of 207,000,000 cu ft.

Extremes. Maximum discharge during year, 36,900 cfs Apr. 3 (gage height, 16.66 ft, from 

graph based on twice-daily wire-weight-gage readings); maximum gage height, 23.08 ft 

Jan. 22 (ice Jam); minimum daily discharge, 110 cfs Aug. 2.

1911-59: Maximum discharge, 136,000 cfs Nov. 4, 1927 (gage height, 35.0 ft, present 

site), from rating curve extended above 70,000 cfs by logarithmic plotting; minimum 

daily, that of Aug. 2, 1959.

Remarks. Records good except those below 1,000 cfs, which are fair. Flow regulated by 

powerplants and by First Connecticut and Second Connecticut Lakes, Lake Francis, Moore 

Reservoir and Comerford Station Fond, Union Village Reservoir (see p. 242), and other 

reservoirs (combined usable capacity, about 1?£ billion cubic feet).

Location. Lat 41°40'23", long 72°54'04", on left bank 700 ft upstream from station of

 New York, New Haven and Hartford Railroad at Forestville, Hartford County, a quarter 

of a mile downstream from Copper Mine Brook, and 65 miles upstream from mouth.

Drainage area. 45.2 sq mi.

Records available. July 1941 to September 1959.

Gage.--Water-stage recorder. Datum of gage is 197.72 ft above mean sea level, datum of 

TT929 (levels by Connecticut State Water Commission).

Average discharge.--18 years, 87.1 cfs (adjusted for storage and diversion).

Extremes. Maximum discharge during year, 2,110 cfs Mar. 6 (gage height, 5.27 ft); minimum, 20 cfs Sept. 28 (gage height, 0.93 ft).

1941-59: Maximum discharge, 11,700 cfs Aug. 19, 1955 (gage height, 13.22 ft, from 

high-water mark in gage house), from rating curve extended above 2,100 cfs on basis of 

slope-area measurements at gage heights 7.3 and 13.22 ft; minimum, 6.5 cfs Sept. 21, 

22, 1941 (gage height, 0.64 ft).

Flood in September 1938 reached a stage of about 7.3 ft, from floodmarlcs (discharge, 

3,800 cfs, on basis of slope-area measurement of peak flow and computation of peak 

flow over dam).

Remarks. Records good except those for period of no gage-height record, which are fair. 

Flow regulated by Whigville Reservoir (see p. 243) and mills upstream. Diversion for 

municipal water supply of city of New Britain from Copper Mine Brook.

MENUNKETESUCK RIVER BASIN 245

1950. Menunketesuck River near Clinton, Conn.

Location. Lat 41°18'10", long 72°31'00", on right bank at Fairy Dell, 100 ft downstream

 FronTCobb's Bridge, 1.7 miles north of Clinton, Middlesex County, 2.4 miles downstream

from Kelseytown Reservoir, and 4.9 miles upstream from mouth. 

Drainage area. 11.6 sq mi.

Records available.--June 1941 to September 1959. 

Gage.--Water-stage recorder. Datum of gage is 23.64 ft above mean sea level, datum 01

1929.

Average discharge .--18 years, 22.3 cfs (adjusted). 

Extremes (unadjusted for storage or diversion).--Maximum discharge during year, 395 cfs

 Apr 3 (gage height, 4.59 ft); minimum, 0.06 cfs Aug. 4, 5 (gage height, 0.77 ft).

1941-59: Maximum discharge, 1,500 cfs Sept. 11, 1954 (gage height, 8.51 ft), from 

rating curve extended above 270 cfs on basis of computation of peak flow over Kelseytown 

dam- no flow at times during August and September 1944, July and August 1957.

Remarks. Records excellent except those for periods of ice effect or backwater from

"leaves or aquatic vegetation, which are good, and those below 4.0 cfs, which are poor. 

The daily discharge record for all periods except those of low flow is a summation of 

daily flow at gaging station and daily diversion from Kelseytown Reservoir as measured 

by venturi meter. During periods of low flow, diversions from Kelseytown Reservoir are 

compensated for by release of water from Killingworth Reservoir which is located about 

2.5 miles upstream from Kelseytown Reservoir on a small tributary of Menunketesuck 

River. The drainage area of Killingworth Reservoir is so small that its yield is considered negligible during periods of low flow when it becomes necessary to draw upon it. 

Therefore, the daily discharge record for periods of low flow July 1-11, July 27 to 

Aug. 9, Aug. 14 to Sept. 2, and Sept. 14-30 is a summation of daily flow at gaging station and daily diversion from Kelseytown Reservoir, minus daily draft on Killingworth 

Reservoir adjusted for daily change in contents in Kelseytown Reservoir. Change in contents in Kelseytown Reservoir and draft on Killingworth Reservoir are determined from a 

continuous chart record of Kelseytown Reservoir water surface. No account is taken of 

evaporation from the reservoir surfaces. Flow at recording gage station regulated by 

Killingworth and Kelseytown Reservoirs and by diversion for domestic water supply from 

Kelseytown Reservoir.

Cooperation. Venturi-meter records and some other data furnished by the Guilford-Chester 

Water Co.

Revisions (water years).--WSP 1301: 1942-44(M).

HOUSATONIC RIVER BASIN 255

2025. Shepaug River at Woodville, Conn.

Location.--Lat 41°43'24", long V3 0 1V'3V", on left end of dam at outlet of Shepaug Reservoir, 1 mile north of Woodville, Litchfield County, and 3.5 miles upstream from 

Bantam River.

Drainage area. 38.0 sq mi.

Records available. October 1935 to September 1959.

Gage. Nonrecording gage at dam or at auxiliary artificial control below dam; read 

usually once daily.

Average discharge. 24 years, 85.9 cfs (adjusted for storage and diversion).

Extremes. Maximum discharge during year, 1,460 cfs Mar. 6; minimum, 2.4 cfs on many days 

(result of regulation).

1935-59: Maximum discharge observed, 13,800 cfs Aug. 19, 1955; no flow at times 

(result of regulation).

Remarks. Records good. Discharge computed on basis of flow over spillway, through floodgaTes, and through fountain at toe of dam. Rating curves for floodgates and fountain 

computed by means of a temporary sharp-crested weir below dam. Rating curve for 

spillway computed for discharges below 18.5 cfs by means of same weir, and for discharges above 18.5 cfs by a formula selected to fit the spillway-crest sections. 

At times of ice effect on spillway, flow computed from gage readings at permanent 

artificial control below the dam, which was calibrated with the sharp-crested weir. 

Water diverted from Shepaug River for municipal supply of Waterbury. Flow regulated 

since September 1933 by Shepaug Reservoir (see p. 266).

Cooperation. Records furnished by Bureau of Engineering, city of Waterbury.

Revisions (water years). WSP 971: 1936-42. WSP 1231: 1937(M) , 1940-41(M) , 1943-45(M) , 

1947, 1948(M) , 1950(M). WSP 1301: 1936.

1928-59: Maximum discharge, 75,800 cfs Oct. 16, 1955 (gage height, 24.50 ft), from 

rating curve extended above 35,000 cfs on basis of computations of flow at Stevenson 

and Derby Dams and slope-area measurements at gage heights 21.5 and 23.5 ft; practically no flow at times, result of regulation.

Remarks. Records excellent. Ordinary flow completely regulated by Stevenson hydroelectric plant. Plow regulated by Lake Candlewood, Lake Lillinonah, Lake Zoar, and Shepaug 

Reservoir, having a combined usable capacity of 6,840,000,000 cu ft (see p. 266), and 

by small diversion from basin at Shepaug Reservoir.

268 DISCHARGE AT PARTIAL-RECORD STATIONS AND MISCELLANEOUS SITES

As the number of streams on which streamflow Information is likely to be desired far exceeds the number of stream-gaging stations feasible to operate at one time , the Geological 

Survey collects limited streamflow data at sites other than stream-gaging stations. When 

limited streamflow data are collected on a systematic basis over a period of years for use 

in hydrologic analyses, the site at which the data are collected Is called a partial-record 

station. Data collected at these partial-record stations are usable in low-flow or floodflow analyses, depending on the type of data collected. In addition, discharge measurements are made at other sites not Included in the partial-record program. These measurements are generally made in times of drought or flood to give better areal coverage to 

those events. Those measurements and others collected for some special reason are called 

measurements at miscellaneous sites.

Records collected at partial-record stations are generally presented in two tables. 

However, no records at crest-stage partial-record stations are available for the 1959 water 

year. A table of discharge measurements at low-flow partial-record stations Is given 

first, followed by a table of measurements made at miscellaneous sites for both low flow 

and high flow.

Low- flow partial-record stations

Measurements of streamflow in the area covered by this report made at low-flow partialrecord stations are given In the following table. Most of these measurements were 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 con 

tinuous records are available , will give a picture of the low-flow potentiality of strea 

The column headed Period of record" shows the water years in which measurements were ma 

at the same, or practically the same, site. de
