SCOPE OF 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, 1952. 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 12,600 gaging stations In the 48 States and at many others in the Territories of Alaska and Hawaii. On September 30, 1952, the Geological Survey and cooperating 

organizations were maintaining 6,700 gaging stations, including those in Alaska and Hawaii. 

Miscellaneous discharge measurements were made at many other points In the 1952 water year.

COOPERATION

New Hampshire: New England Power Association.

Vermont: New England Power Association.

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

of the Interior and the Water Resources Division, Department of Resources and Development, 

Canada. On waters adjacent to the international boundary, certain stations are maintained 

jointly by the United States and Canada under the terms of the 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.

DIVISION OF WORK

The stream gaging was done by the Water Resources Division of the Geological Survey, 

Carl G. Paulsen, chief hydraulic engineer, under the direction of Joseph V. B. Wells, 

chief of the Surface Water Branch. The data for stations in the several States were collected and prepared for publication under the supervision of the district engineers at the 

offices listed below. The records were reviewed and the manuscript prepared for publication under the direction of B. J. Peterson, chief, Annual Reports Section.

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. Provisional 

records of discharge prior to publication, and other unpublished data concerning the 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 terms 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
EXPLANATION OP DATA 3

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 noncontributlng areas, 

within the area unless otherwise noted.

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, 1952, 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 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 of 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, arl 

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.

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 "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 of gages, locations, and daturas of previous gages for which discharge 

records are generally equivalent to those at the present site. Under "Average discharge" 

is given the average discharce 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 report 

number, "W" means water-supply paper. 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 

ares 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.

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 

dally 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
ACCURACY OF FIELD DATA AND COMPUTED RESULTS 7

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 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 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 

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.

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 Interpretattion of records.
8 SURFACE WATER SUPPLY, 1952, PART 1-A

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 

various parts are indicated by the following list and the map in figure 2.

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

Miscellaneous 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
PUBLICATIONS

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.

Each of the reports on the surface-water supply for the year 1939 (Water-SUpply Paper 

871 for the North Atlantic slope basins, Maine to Connecticut) contains, for the area included in that report, a summary of yearly discharge at gaging stations at which 10 or 

more complete years of record had been collected. These summaries were reprinted separately.

Reports also have been published that are compilations of records for various areas, 

usually a single State or drainage basin. These reports contain records previously published (some of which may have been revised), as well as some records not contained in the 

annual series of water-supply papers. The following table lists reports of this type for 

the North Atlantic slope basins, Maine to Connecticut.

Remarks. An artificial cut has been made through a low divide between Souadabscook Strean 

and Black Stream which enters Kenduskeag Stream 7.3 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. 

At odd times amount of diversion has been measured. When flow at gaging station is above; 

900 cfs, current meter measurements have shown that Souadabscook Stream has accounted fo1- 

7.5 percent of this.

Revisions. Revised figures of discharge, in cubic feet per second, for water years 1S09-15, 

1917-18, superseding figures published in previous water-supply papers, are given herein. 

Complete table of daily discharge is given for water year 1914, but only revised discharges are given for other water years.

Presumpscot River at outlet of Sebago Lake, Maine

Location. Lat 43"49"05", long. 70°27'00", at dam of hydroelectric plant at Eel Weir 

 Palls, 1 mile downstream from lake outlet, Cumberland County.

Drainage area.--436 sq mi.

Records available. January 1887 to September 1952.

.--Float gages in forebay and tailrace of hydroelectric plant at Eel Weir Falls and 

Ftaff gage at dam on outlet of Sebago Lake.

Average discharge. 65 years, 657 cfs.

Remarks. Discharge computed from Alien meter records for each of 3 pairs of water wheels 

and from records of openings of 2 regulating gages 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. Flow completely regulated by Crystal, Highland 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 (revised).

Cooperation. Records furnished by S. D. Warren Co.

Revisions (water years). W 261: Drainage area. W 1301: 1920-50 (adjusted monthly runorr in inches).

Discharge, in cubic feet per second, water year October 1951 to September 1952

Merrimack River at Franklin Junction, N. H.

Location. Lat 43°25'25", long. 71°39'10", on right bank at Franklin Junction, Merrimack 

County, 1 mile downstream from confluence of Pemigewasset and Winnipesaukee Rivers.

Drainage area. 1,507 sq mi.

Records available. July 1903 to September 1952.

Gage. Water-stage recorder. Datum of gage is 250.4 ft above mean sea level, unadjusted. 

Prior to Sept. 13, 1923, chain gage at bridge 350 ft downstream at same datum.

Average discharge . 47 years (1905-52), 2,775 cfs.

Extremes. 1912-13: Maximum discharge during water year, 29,600 cfs Mar. 28 (gage height, 

18.3 ft, from graph based on gage readings); minimum daily, 850 cfs July 5.

1951-52: Maximum discharge during year, 21,300 cfs June 3 (gage height, 15.40 ft); 

minimum daily, 368 cfs Aug. 23.

1903-52: Maximum discharge, 83,000 cfs Mar. 19, 1936 (gage height, 36.4 ft, from 

floodmarks), from rating curve extended above 30,000 cfs on basis of velocity-area 

studies, slope-area determination, and computation of flow over dam; minimum daily, 

225 cfs Oct. 23, 1948.

Revisions. The figures of maximum discharge for the water years 1904-9, 1911-13, 

1915-17, 1919, 1922, some of which have been revised, superseding those published in 

the water-supply papers indicated, are contained in the following table.

cfs May 16 (gage height, 11.52 ft), superseding figure published in Water-Supply Paper 

821.

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

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

pages 137, 173 for description and monthly change in contents of many of these reservoirs .

Revisions. Revised figures of discharge for the water year 1937, superseding those published in Water-Supply Paper 821, are given herewith.

Extremes. Maximum discharge during year, 4.040 cfs Dec. 21 (gage height, 8.67 ft); minimum, 14 cfs Oct. 7 (gage height, 1.65 ft); minimum dally, 20 cfs July 19.

1929-52: Maximum discharge, 20,900 cfs Sept,. 21, 1938 (gage height, 19.45 ft, from 

f loodmarks ) , by computation of peak flow over dasi 1 mile upstream and over dam on Little 

River 2 miles upstream from its mouth; minimum, 8.5 cfs Oct. 26, 1935; minimum dally, 

11 cfs Oct. 5, 12, 1930.

Remarks . Records excellent. City of Putnam diverts an average of less than 1 mgd from 

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

flow, caused by many dams and reservoirs above station, largest of which is Lake 

Chaubunagungamaug with an estimated usable capacity of 207,000,000 cu ft.

Location. Lat 43°38i50", long. 72°18'45", on right bank SO ft downstream from railroad

 bridge at White River Junction, Windsor County, and 500 ft downstream from White

River.

Drainage area. 4,092 sq mi.

Records available. October 1911 to September 1952. 

Gage.--Water-stage recorder. Datum of gage is 321.52 ft above mean sea level, datum of

 1929. Prior to June 16, 1918, painted staff gage on downstream side of pier of railroad bridge 50 ft upstream at same datum. June 16, 1918, to Nov. 2, 1930, chain gage 

at various locations on upstream and downstream sides of railroad bridge at same 

datum.

Average discharge.--41 years, 7,203 cfs (adjusted for storage).

Extremes.--Maximum discharge during year, 56,500 cfs June 2 (gage height, 21.15 ft, from 

graph based on gage readings); minimum daily, 155 cfs Aug. 31.

1911-52: 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. 31, 1952.

Remarks. Records good except those below 3,000 cfs, which are fair. Flow regulated by

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

Comerford Station Pond, Union Village Reservoir (see p. 302), and other reservoirs 

(combined usable capacity, about 12f billion cu ft).

Cooperation. Wire-weight-gage readings furnished by U. S. Weather Bureau.

read once daily. Datum of gage is 508.9 ft above mean sea level, datum of 1929. Prior 

to April 1910, staff gage at site 1,200 ft downstream at different datum. April to 

August 1910, staff gage and sharp-crested weir at site 300 ft downstream at different 

datum.

Average discharge. 36 years (1916-52), 21.1 cfs.

Extremes. Maximum discharge during year, 336 cfs Apr. 6 (gage height, 3.90 ft, from 

graph based on gage readings); minimum discharge, 1.0 cfs Aug. 30.

1916-52: Maximum discharge, 1,540 cfs Mar. 19, 1936 (gage height, 6.30 ft, from 

floodmarks), from rating curve extended above 280 cfs on basis of slope-area determinations at gage heights 5.62 and 6.30 ft; minimum, 0.2 cfs Sept. 4,5, 1929.

Sage. Water-stage recorder. Datum of gage is 388.60 ft above mean sea level, datum of ~n:929.

Average discharge. 17 years, 186 cfs.

Extremes.--Maximum discharge during year, 5,420 cfs June 1 (gage height, 7.85 ft), from 

rating curve extended above 2,700 cfs on basis of computation of flow over dam at gage 

heights 11.93 and 12.95 ft; minimum, 11 cfs Aug. 30, 31.

1935-52: Maximum discharge, 21,800 cfs Sept. 21, 1938 (gage height, 15.5 ft, from 

floodmarks), mean of slope-area determination and computation of flow over dam; minimum, 4.2 cfs Aug. 28, 29, 1949.

Remarks. Records good except those for periods of ice effect or shifting control, which 

are fair. Some diurnal fluctuation at low flow caused by mill above station.

304 MENUNKETESUCK RIVER BASIN

Menunketesuck River near Clinton, Conn.

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

from Cobb' a 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 1952.

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

T929.

Average discharge.--11 years, 20.9 cfs (adjusted).

Extremes (unacQtmed for storage or diversion). Maximum discharge during year, 370 cfs 

Dec. 21 and Mar. 11; maximum gage height, 4.52 ft Dec. 21; minimum discharge, 0.10 cfs 

Oct. 1 (gage height, 0.64 ft).

1941-52: 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 backwater from rocks and debris 

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 periods of low flow Oct. 1-12, 15-25, June 26 to Aug. 10, Sept. 13-15, 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 staffgage 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. 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.

Shepaug River at Woodville, Conn.

Location. Lat 41 "43'24", long. 73"17'37", at 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 1952.

Gage. Nonrecording gage read usually once daily.

Average discharge.--17 years, 84.0 cfs (adjusted for storage and diversion).

Extremes. Maximum discharge during year from graph based on gage readings, 2,400 cfs 

June 1; minimum observed, 2.4 cfs at times.

1935-52: Maximum discharge observed, 6,000 cfs Sept. 21, 1938; no flow at times 

(result of regulation).

Revisions. The figures of maximum discharge for some water years have been revised 

as shown in "the following table. They supersede those published in water-supply papers 

indicated.

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. Water diverted 

from Shepaug River for municipal supply of Waterbury. Plow regulated since September 

1933 by Shepaug Reservoir (see p. 322).

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

Revisions (water years). W 971: 1936-42. Revised figures of discharge, in cubic feet per

Records available. October 1930 to September 1952.

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

1929 (levels by Corps of Engineers).

Average discharge. 22 years, 241 cfs (adjusted for storage and diversion).

Extremes. Maximum discharge during year, 5,080 cfs June 1 (gage height, 8.91 ft); minimum discharge, 2 cfs Oct. 6 (gage height, 1.25 ft).

1930-52: 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, that of Oct. 6, 1952.

Remarks. Records good. Water diverted from Shepaug Reservoir for municipal supply of 

cTffy of Waterbury. Flow regulated by Shepaug Reservoir (see p. 322). Diurnal fluctuations from an unknown cause during low flow.

Location.--Lat 41°28'50", long. 73°13'30", on right bank 2QQ ft upstream from highway 

bridge, 800 ft downstream from Bullet Hill Brook, 0.6 mile west of Southbury, New 

Haven County, and 5.8 miles upstream from mouth.

Drainage area.--75.3 sq mi.

Records available.--June 1938 to September 1952.

Gage. Water-stage recorder. Datum of gage is 165.60 ft above mean sea level (levels 

by Corps of Engineers).

Average discharge.--20 years, 126 cfs.

Extremes.--Maximum discharge during year, 2,500 cfs Mar. 11 (gage height, 8.88 ft), from 

rating curve extended above 1,200 cfs as explained below; minimum, 8.6 ofs Oct. 6, 7 

(gage height, 2.50 ft).

1932-52: Maximum discharge, 7,420 cfs Sept. 21, 1938 (gage height, 16.0 ft from 

floodmarks), from rating curve extended above 1,200 cfs on basis of computation of 

peak flow over dam 2 miles downstream; minimum, 3.3 cfs Aug. 27, 1949 (gage height, 

2.32 ft).

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

318 HOUSATONIC RIVER BASIN

Housatonlc 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, Fairfleld County,

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

Drainage area. 1,545 sq ml.

Records available. August 1928 to September 1952. 

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.--24 years, 2,560 cfs (adjusted for storage and diversion since 1936). 

Extremes. Maximum discharge during year, 22,700 cfs Apr. 6 (gage height, 13.85 ft);

minimum, 55 cfs July 26 (gage height, 0.64 ft); minimum dally, 67 cfs July 26.

1928-52: 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 period 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. 322), and by small diversion from the

basin at Shepaug Reservoir. 

Revisions (water years). W 711: 1929(M). W 781: Drainage area. Corrected figures of

monthly and annual discharges for the water year 1951, superseding those published in

Water-Supply Paper 1201, are given herewith.
