SCOPE OP WORK

This volume is one of a series of 18 reports presenting measurements of stage, discharge, and content of streams, lakes, and reservoirs in the United States during the 

water year ending September 30, 1953. Since 1888, when the United States Geological 

Survey first studied streamflow in relation to problems of irrigation, similar measurements have been made at more than 12,800 gaging stations in the 48 States and at many 

others in the Territories of Alaska and Hawaii. On September 30, 1953, the Geological 

Survey and cooperating organizations were maintaining 6,750 gaging stations, including 

those in Alaska and Hawaii. Discharge measurements only were made at many other points 

in the 1953 water year, most of which are published at the end of 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:

Connecticut: State Water Commission, E. I. NcDonough, chairman, succeeded 

by H. P. Koppleraan and W. S. Wise, director; city of Hartford, Department of 

Public Works, C. W. Cooke director; city of New Britain, Board of Water 

Commissioners, J. J. Kiniry, chairman.

Maine: Maine Public Utilities Commission, S. T. Pike, chairman. 

Massachusetts: State Department of Public Health, Vlado Getting, commissioner, 

succeeded by S. B. Kirkwood, and C. I. Sterling, Jr., chief sanitary engineer; 

State Department of Public Works, W. P. Callahan, commissioner, succeeded by 

J. A. Volpe; Metropolitan District Commission, E. P. Copell, commissioner, 

succeeded by C. W. Greenough, and H. J. Toole, director and chief engineer of 

Water Division.

New Hampshire: Water Resources Board, W. G. White, chairman. 

Rhode Island: State Department of Public Works, Henry Ise', chief of Division 

of Harbors and Rivers.

Vermont: Water Conservation Board, Philip Shutler, commissioner. 

Assistance In the form of funds or services was given by the Corps of Engineers, 

Department of the Army, in collecting records published herein for 35 gaging stations, of 

which 11 were in Massachusetts, 14 in New Hampshire, 1 in Rhode Island, and 9 in Vermont. 

Pull cooperation exists between the Geological Survey of the United States Department 

of the Interior and the Water Resources Division, Department of North Affairs and 

National Resources, Canada. On waters adjacent to the international boundary, certain 

stations are maintained Jointly by the United States and Canada under the terms of the
2 SURFACE WATER-SUPPLY, 1953, PART 1-A

Boundary Waters Treaty of 1909, and others are maintained under a subsequent agreement 

between the two Governments. The records from all these stations are obtained in such a 

manner as to be equally acceptable and available in both countries. These stations are 

herein designated as international gaging stations.

The following organizations aided in collecting records:

Connecticut: Metropolitan Water Bureau of Hartford, borough of Qroton, city of 

Waterbury, Bridgeport Hydraulic Co., Collins Co., Connecticut Light & Power Co., 

Connecticut Power Co., Parmington River Power Co., Quilford-Chester Water Co., and 

Rockville Water & Aqueduct Co.

Maine: Bangor Hydro-Electric Co., St. Croix Paper Co., and Union Water Power Co. 

Massachusetts: New England Power Association, Western Massachusetts Electric 

Co., and Worcester Electric Light Co.

New Hampshire: New England Power Association. 

Vermont: New England Power Association.

DIVISION OF WORK

The stream-gaging work was done by the Water Resources Division of the Geological 

Survey under the direction of personnel shown in the preface. The data for stations in 

the several States were collected and prepared for publication in the district offices 

listed below.

records of discharge prior to publication, and other unpublished data concerning the 

gaging station records may usually 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:

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.

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 is the depth to which an area would be covered if all the water draining from it in a given period were uniformly distributed on its surface. The term is 

used for comparing runoff with rainfall, which is also usually expressed in Inches.

Acre-foot is the quantity of water required to cover an acre to the depth of 1 foot

and is"equivalent to 43,560 cubic feet. The term is commonly used in relation to storage 

for irrigation.

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 noneontributing 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 OP LISTING GAGING STATIONS

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.

EXPLANATION OP 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
4 SURFACE WATER SUPPLY, 1953, PART 1-A

methods are described in Water-Supply Paper 888 and are also outlined in standard textbooks on the measurement of stream discharge. Typical structures in use at gaging stations are shown in figure 1.

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

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 

and runoff of the stream. Records are published for the water year which begins on 

October 1 and ends- on September 30. . A calendar for the water year 1953 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 the 

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). 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 

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 those 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
EXPLANATION OF DATA 7

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

height may not Indicate the true dally 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 dally 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 nonrecordlng gages, the table of dally 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 dally 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 dally discharge, the values for the maximum day and the minimum day for 

each month are underlined. If the value 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 values; 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. Runoff 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"). Values 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 values of maximum are the maximum 

daily discharges, not the momentary discharges when the water was at crest stage. Likewise, the mlnlmums 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 

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 usually given in the first report in which data for the reservoir are published, 

but it is omitted from succeeding reports.
8 SURFACE WATER SUPPLY, 1953, PART 1-A

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.

Runoff 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, values of 

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

storage or diversion records are included to indicate the extent of the regulation or diversion, or unless satisfactory adjustments can be made 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 

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 of 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

To facilitate publication of the annual series of reports, the area of the United 

States is divided into 14 parts whose boundaries coincide with certain natural drainage 

lines. Formerly, the results of streamflow measurements were published in 14 volumes, one 

for each of the 14 parts. Beginning with the reports for 1951, the records are published 

in 18 volumes, there being 2 volumes each for Parts 1, 2, 3, and 6. The boundaries of the

The records at nost of the stations discussed in these reports extend over many years. 

Discharge measurements at many points other than regular gaging stations have been made 

each year and are published under "Miscellaneous discharge measurements" at the end of 

each report. The streams and points of measurement are listed in the same order as the 

streams and gaging stations in the body of the report. An index of the records obtained 

before 1904 has "been published in Water-Supply Paper 119.

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

has been published as WSP 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 reexamined and revised where 

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

Records of discharge have been published also in State reports. Most of these records 

are also compiled in Water-Supply Paper 1301, however, some of them are not contained in

HYDROLOGIC CONDITIONS

Streamflow during the 1953 water year averaged above normal over most of the North 

Atlantic slope basins, Maine to Connecticut due to excessive rainfall during the months 

of December to March. In March, the floods in Maine were generally about as large as the 

record-breaking floods of 1936. Deficient runoff occurred over most of the area covered 

by this report during the months of October, November, June to September with many streams 

dropping to new lows for the month of September. For two key gaging stations in the area 

covered by this report, a comparison of monthly and yearly mean discharges during the 

1953 water year with the median discharge for the 25-year period 1921-45 is shown in

40 PENOBSCOT RIVER BASIN

Kenduskeag Stream near Kenduskeag, Maine

Location. Lat 44°53'50", long. 68°53'00", on right bank 300 ft upstream from highway 

bridge, 1.8 miles downstream from Black Stream, and 2.9 miles south of Kenduskeag, 

Penobscot County.

Drainage area.--178 sq mi.

Records available.--October 1941 to September 1953.

Gage.--Water-stage recorder. Altitude of gage is 97 ft (from topographic map).

Average discharge. 12 years, 288 cfs.

Extremes. Maximum discharge during year, 4,440 cfs Mar. 28 (gage height, 12.14 ft); minimum, 3.8 cfs Oct. 2 (gage height, 1.22 ft).

1941-53: Maximum discharge, that of Mar. 28, 1953; maximum gage height, 12.56 ft 

Mar. 11, 1942 (ice jam); minimum discharge, 1.0 cfs Sept. 30, Oct. 1, 1948 (gage height, 

1.09 ft).

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

which are fair. An artificial cut has been made through a low divide between Souadabscook Stream and Black Stream, which enters Kenduskeag Stream 1.8 miles above station. 

During high stages of Souadabscook Stream, part of its flow passes through the cut into 

Kenduskeag Stream; at low stages of Souadabscook Stream, all flow continues down its 

own channel.

Lake Winnipesaukee Outlet at Lakeport, N. H.

Location.--Lat 43"32'55", long. 71°27'55", 100 ft upstream from highway bridge across Paugus Bay at Lakeport, Belknap County.

Drainage area 363 sq mi.

Records available. January 1860 to December 1911 (monthly gage heights only), June 1933 

to September 19s3.

Gage.--Water-stage recorder, Keeler deflection meter, and measuring flume. Datum of gage 

is 500.55 ft above mean sea level, datum of 1929. Prior to January 1912, staff gage at 

site 150 ft downstream at same datum. June 1, 1933, to Sept. 30, 1936, staff gage and 

continuous recording current meter at same site and datum. Oct. 1, 1336, to May 22, 

1944, discharge computed from flow over soillway and through gates and wheels at site 

150 ft downstream.

Average discharge.--20 years, 525 ofs (adjusted for storage).

Remarks.--Records good. Flow completely regulated by Winnipesaukee (see preceding page), 

Wentwoith, Merrymeeting (see p. 113), and other lakes. Daily discharge comruted from 

relation belween discharge, stage, and deflection of vane in measuring flume.

1934 to September 1935.

Gage. Water-stage recorder. Altitude of gage is 430 ft (from topographic map). Prior 

To Oct. 1, 1934, chain gage at site 5 miles downstream at different datum.

Average discharge.--23 years (1918-20, 1927-53), 214 cfs (adjusted to present site).

Extremes.--Maximum discharge during year, 8,320 cfs Apr. 4, 5 (gage height, 7.10 ft); minimum, 18 cfs Nov. 5-9, 11-15, Aug. 3, 4; minimum daily, 18 cfs Nov. 5-9, 11-15, Aug. 3, 4.

1918-20, 1927-53: Maximum discharge, 11,000 cfs Mar. 19, 1936 (gage height, 11.78 

ft, from floodmarks), from rating curve extended above 6,700 cfs on basis of slope-area 

and critical-depth determinations of peak flow; minimum, 3 cfs Sept. 17, 1941 (gage 

height, 1.20 ft); minimum daily, 10 cfs Aug. 14, 1950.

Remarks. Records excellent except those below 50 cfs and those for periods of ice effect, 

which are good. High flow regulated by Blackwater Reservoir since 1941 (see p. 113). 

Some regulation at low flow by mill above station.

MERRIMACK RIVER BASIN 

Merriraack River near Goffs Falls, below Manchester, N. H.

101

Location. Lat 42°56'55", long. 71°27'45", on right bank 0.8 mile downstream from Bowman 

Brook, 1.3 miles north of Goffs Falls, Hillsboro County, and 2.3 miles downstream from 

Piscataquog River,

Drainage area. 3,092 sq mi.

Records available. November 1936 to September 1953.

Gage. Water-stage recorder. Altitude of gage is 105 ft (from topographic map).

Average discharge. 17 years, 5,327 ofs.

Extremes. Maximum discharge during year, 46,900 cfs Mar. 28 (gage height, 13.90 ft); minimum daily, 312 cfs Aug. 16.

1936-53: Maximum discharge, 102,500 cfs Sept. 23, 1938 (gage height, 25.87 ft), 

from rating curve extended above 48,000 cfs on basis of computations of flow over dam 

at gage heights 25.87 and 35.19 ft; minimum daily, 154 cfs Sept. 5, 1949.

Maximum discharge known, 150,000 cfs Mar. 20, 1936 (gage height, 35.19 ft, from 

floodmarks), from rating curve extended above 48,000 cfs by method explained above.

Remarks. Records excellent except those for periods of ice effect, which are good. Flow 

regulated by powerplants, by Franklin Falls Reservoir since 1942, and by Squam, Newfound, Winnipesaukee, Winnlsquam, and other lakes and reservoirs above station. See 

pages 85, 113 for description and monthly change in contents of many of these 

reservoirs.

Revisions (water years). WSP 1231: 1937. The maximum and minimum discharge for water 

year 1937 have been corrected to: maximum discharge, 33,700 cfs May 16, 1937 (gage 

height, 11.52 ft); minimum daily, 450 cfs Sept. 16, 1937. Those published in WSP 1231 

were for the wrong year.

Location.--Lat 42°51'25", long. 71 0 30'30", on left bank at head of Atherton Falls, at 

Merrimack, Hillsboro County, If miles upstream from mouth.

Drainage area. 171 sq mi.

Records available. July 1909 to September 1953.

. Water-stage recorder. Datum of gage is 160.58 ft above mean sea level, unadjusted 

levels by Corps of Engineers). Prior to Apr. 12, 1911, staff gage at site 300 ft

downstream at datum 0.38 ft lower. Apr. 12, 1911, to Oct. 14, 1913, chain gage at

present site and datum.

Average discharge.--44 years, 283 cfs.

Extremes. Maximum discharge during year, about 4,650 cfs Mar. 16 (gage height not determined); minimum, 21 cfs Sept. 5.

1909-53: Maximum discharge, 16,900 cfs Mar. 19, 1936 (gage height, 16.2 ft), i'rom 

rating curve extended above 7,300 cfs on basis of velocity-area studies and computation 

of flow over dam at gage height 12.78 ft; minimum, 13 cfs Sept. 9, 1926.

Remarks. Records excellent except those for periods of ice effect, which are good, and 

those for period of no gage-height record, which are fair. Some diurnal fluctuation 

caused by mill above station.

Records available. June 1916 to September 1953.

Gage.--Water-stage recorder and concrete control. Datum of gage is 613.71 ft above mean 

sea level, datum of 1929 (Corps of Engineers benchmark). Prior to Oct. 26, 1948, 

staff gage at site 0.2 mile upstream at datum 14.40 ft higher.

Average discharge. 37 years, 84.3 cfs (adjusted for storage).

Extremes. Maximum discharge during year, 547 cfs Apr. 8 (gage height, 4.78 ft); minimum, 

0.2 cfs Mar. 29, 30; minimum daily, 0.2 cfs Mar. 29.

1916-53: Maximum discharge, 5,140 cfs Sept. 21, 1938 (gage height, 8.60 ft, from 

floodmarks, site and datum then in use), from rating curve extended above 1,500 cfs 

on basis of determination of peak flow by computation of flow over dam and contractedopening determination; minimum, 0.03 cfs Jan. 4, Mar. 3, 1949; minimum daily, that of 

Mar. 29, 1953.

Remarks. Records excellent except those above 400 cfs and those for periods of shifting 

control or no gage-height record, which are good. Flow regulated by Tully Reservoir 

since November 1948 (see pp. 233,234).

CONNECTICUT RIVER BASIN 

Connecticut River at Turners Palls, Mass.

Location.--Lat 42°36'40", long. 72°33'20", at dam of Western Massachusetts Electric Co 

at Turners Palls, Franklin County, 0.2 mile upstream from Palls River.

Drainage area.--7.163 sq mi.

Records available. January 1915 to September 1953.

Average discharge.--38 years, 11,860 cfs (adjusted for storage).

Remarks. Discharge computed by adding flow over and through dam, flow for factories 

through canal that diverts around dam, and flow through power stations 1 and 2 of 

Western Massachusetts Electric Co. Plow regulated by powerplants and by First Connecticut and Second Connecticut Lakes, Lake Francis since 1940, Comerford Station 

Pond since 1930 (see p. 233), and other reservoirs (combined usable capacity, about 

19? billion cubic feet).

Cooperation.--Records furnished by Western Massachusetts Electric Co.

Records available. December 1939 to September 1953.

Gage. Water-stage recorder. Datum of gage is 458.36 ft above mean sta level, datum of 

~1929.

Average discharge. 14 years, 180 cfs.

Extremes. Maximum discharge during year, 6,500 cfs Mar. 24 (gage height, 8.32 ft), from 

rating curve extended above 3,600 efs on basis of computation of flow over dam at gage 

height 9.62 ft; minimum, 5.3 cfs Sept. 5, 12; minimum daily, .0 cfs Sept. 2, 4.

1939-53: Maximum discharge, 10,000 cfs Dec. 31, 1948 (gage height, 9.62 ft), from 

rating curve extended above 3,600 cfs as described above; minimum daily, 5.1 cfs 

Oct. 3, 1948.

Remarks.--Records excellent except those for periods of fragmentary gage-height record, 

which are good, and those for periods of ice effect or no gage-height record, which 

are fair. Diurnal fluctuation at low flow caused by mill above station; prior to 

1950, greater regulation by mill.

"at Sunderland." Records published for both sites October 1929 to September 1932.

Gage.--Water-stage recorder. Datum of gage is 99.87 ft above mean sea level, datum of 

T929. Prior to Oct. 1, 1917, chain gage, Oct. 1, 1917, to Oct. 8, 1921, water-stage 

recorder used for low stages, chain gage otherwise, and Oct. 9, 1921, to Sept. 30, 

1932, water-stage recorder, at site 9 miles downstream at datum 1.00 ft lower. Gages 

at both sites in operation Oct. 1, 1929, to Sept. 30, 1932.

Average discharge . 49 years, 13,730 cfs (adjusted for storage since October 1923).

Extremes. Maximum discharge during year, 123,000 cfs Mar. 28 (gage height, 35.40 ft); 

minimum daily, 384 cfs Aug. 23, 30.

1904-53: Maximum discharge, 236,000 cfs Mar. 19, 1936 (gage height, 49.2 ft, from 

floodmarks), from rating curve extended above 160,000 cfs; minimum daily, 325 cfs 

July 4, 1949.

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

and those below 1,500 cfs, which are fair. Plow regulated by powerplants and by First 

Connecticut and Second Connecticut Lakes, Lake Francis since 1940, Comerford Station 

Pond since 1930 (see p. 233), and other reservoirs (combined usable capacity, about 

27? billion cubic feet).

dam; minimum daily, 16 cfs several times in 1929-31. 

Remarks. Records excellent except those for periods of backwater from aquatic vegetation,

 wKTch are good. Diversion since 1941 from 186 sq mi in Swift River basin and as needed 

during period Oct. 15 to June 14 of each year since 1931 from 97 sq ml in Ware River 

basin for Boston metropolitan district and, since 1950, for city of Chicopee. Diversion from Ludlow Reservoir for Springfield and, prior to 1952, for Chicopee. Flow 

regulated by ppwerplants above station, by Quabbin Reservoir on Swift River since 1939 

(see p. 233), and by smaller reservoirs.

t Affected by diversion from Ware River and diversion to Wachusett Reservoir and Chlcopee Valley 

aqueduct.
MENUNKETESUCK RIVER BASIN 

Menunketesuck River near Clinton, Conn.

235

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

from Cobb'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 1953.

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

T929.

Average discharge. 12 years, 21.6 cfs (adjusted).

Extremes (unadjusted for storage or diversion) . Maximum discharge during year, 820 cfs 

Mar. 13 (gage height, 6.2b ft); minimum, 0.015 cfs Sept. 28-30 (gage height. 0.65 ft).

1941-53: Maximum discharge, 870 cfs Nov. 12, 1947 (gage height, 6.72 ft), from 

rating curve extended above 270 cfs on basis of logarithmic plotting; no flow at times 

during August and September 1944; minimum gage height, 0.48 ft Sept. 9-12, 1944.

Remarks.--Records excellent except those for periods of no gage-height record OP backwater from rocks and those below 2.5 cfs, which are good. 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 period of low flow June 11 to Sept. 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. Draft on Killingworth Reservoir is determined at a staff-gage 

station Just below spillway. Change in contents in Kelseytown Reservoir is determined 

at a temporary recording station at dam. No account is taken of evaporation from the 

reservoir surfaces. Plow 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 

Shepaug River at Woodville, Conn.

245

Location. Lat 41°43'24", long. 73°17'37", at left end of dam at outlet of Shepaug Reser- 

 voir, 1 mile north of Woodville, Lltchfleld County, and 3.5 miles upstream from Bantam 

River.

Drainage area. 38.0 sq ml.

Records available. October 1935 to September 1953.

Gage. Nonrecording gage read usually once dally.

Average discharge. 18 years, 85.4 cfs (adjusted for storage and diversion).

Extremes. Maximum discharge during year from graph based on gage readings, 1,890 cfs 

Jan. 24; no flow at times.

1935-53: Maximum discharge observed, 6,000 cfs Sept. 21, 1938; 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 dam, which was calibrated with sharp-crested weir. Water diverted from Shepaug 

River for municipal supply of Waterbury. Plow regulated since September 1933 by 

Shepaug Reservoir (see p. 252).

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

Location.--Lat 41°32'59", long. 73°19'49", on right bank at downstream side of Wellers 

highway bridge on Wellers Bridge road, half a mile south of Roxbury Station, l£ miles 

southwest of village of Roxbury, Litchfield County, and 2.4 miles upstream from Jacks 

Brook.

Drainage area. 133 sq mi.

Records available. October 1930 to September 1953.

Gage. water-stage recorder. Datum of gage is 281.98 ft above mean sea level, datum of 

T929 (levels by Corps of Engineers).

Average discharge. 23 years, 245 cfs (adjusted for storage and diversion).

Extremes. Maximum discharge during year, 4,530 cfs Jan. 24 (gage height, 8.35 ft); minimum, 5.1 cfs Sept. 7 (gage height, 1.36 ft).

1930-53: Maximum discharge, 10,500 cfs Sept. 21, 1938 (gage height, 12.8 ft, from 

floodmarks), from rating curve extended above 3,500 cfs by logarithmic plotting on 

basis of two computations of flow over dam; minimum, 2 cfs Oct. 6, 1951 (gage height, 

1.25 ft).

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

which are fair. Water diverted from Shepaug Reservoir for municipal supply of city of 

Waterbury. Plow regulated by Shepaug Reservoir (see p. 252). Diurnal fluctuations 

from an unknown cause during low flow.

Revisions; (water years). WSP 801: 1931-36. WSP 971: 1936, 1939-40, 1942. WSP 1301:

HOUSATONIC RIVER BASIN

Housatonic River at Stevenson, Conn.

Location. Lat 41°23'05", long. 73°09'55", on left bank in New Haven County, 0.2 mile 

downstream from dam of Connecticut Light & Power Co. at Stevenson, Fairfield County, 

0.2 mile upstream from Eightmile Brook, and at mile 19.2.

Drainage area. 1,545 sq mi.

Records available. August 1928 to September 1953.

Gage. Water-stage recorder. Datum of gage is 24.98 ft above mean sea level, datum of 

T929 (levels by Corps of Engineers).

Average discharge. 25 years, 2,592 cfs (adjusted for storage and diversion).

Extremes. Maximum discharge during year, 25,300 cfs Jan. 24 (gage height, 14.51 ft); 

minimum, 47 cfs July 16 (gage height, 0.54 ft); minimum daily, 64 cfs Oct. 26.

1928-53: Maximum discharge, 69,500 cfs Mar. 12, 1936 (gage height, 23.5 ft, from 

floodmarks), from rating curve extended above 35,000 cfs on basis of computation of 

peak flow at Stevenson and Derby dams and slope-area determination of peak flow; practically no flow at times, result of regulation.

Remarks. Records excellent except those for periods of no gage-height record, which are 

good. Ordinary flow completely regulated by Stevenson hydroelectric plant. Plow regulated by Lake Candlewood, Lake Zoar, and Shepaug Reservoir having a combined usable 

capacity of 6,600,000,000 cu ft (see p. 252), and by small diversion from basin at 

Shepaug Reservoir.
