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, 1954. 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 13,050 gaging stations in the 48 States and at many others in 

the Territories of Alaska and Hawaii. On September 30, 1954, 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 

1954 water year, most of which are published at the end of each 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, H. P. Koppleman, chairman, 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, 

succeeded by Russell Willoughby, and G. W. Wood, chief engineer. 

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

Massachusetts: State Department of Public Health, S. B. Kirkwood, commissioner, 

and C. I. Sterling, Jr., chief sanitary engineer; State Department of Public Works,

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records of discharge prior to publication, and other unpublished data concerning the 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 UF 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 (cfsra) 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.
EXPLANATION OF DATA 3

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 OF 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 ia 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 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. Typical structures in use at gaging stations are shown in figure 1.
4 SURFACE WATER SUPPLY, 1954, PART 1-A

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 

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

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 1954 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 daturns 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 

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

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. 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"). 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 dally 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, 1954, 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, figures 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. 

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 

publications of the Geological Survey. The following table contains a list of these reports for the area covered by this report.

HYDROLOGIC CONDITIONS

Strearaflow during the 1954 water year averaged slightly above median to excessive over 

most of the area covered by this report. Runoff was deficient over most of the area 

during most of October; heavy precipitation late in October brought runoff for the month 

up to near median. Runoff was also deficient in southern New Hampshire and southwestern 

Maine during January and in southeastern Massachusetts during March. Medium-high stages 

were experienced over most of the area August 31 and September 1 due to hurricane Carol. 

Moderate floods and record or near record-high monthly runoff for September occurred over 

most of the area as a result of the passage of hurricane Edna and accompanying rainfall 

on Sept. 11. For two key gaging stations in the area covered by this report, a comparison of the monthly and yearly mean discharge during the 1954 water year with the median 

discharge for the 35-year period 1921-45 is shown in figure 3 on the following page .

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 1954.

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

Average discharge. 13 years, 305 cfs.

Extremes.--Maximum discharge during year, 6,440 cfs Sept. 12 (gage height, 14.83 ft); minimum not determined (occurred during period of no gage-height record).

1941-54: Maximum discharge, that of Sept. 12, 1954; minimum, 1.0 cfs Sept. 30, 

Oct. 1, 1948 (gage height, 1.09 ft).

Remarks. Records good except those for periods of ice effect or 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. On Apr. 22, 1954, 205 cfs was measured flowing through the cut.

Lake Winnipesaukee at The Weirs, N. H.

Location . Lat 43°36'20", long 71°27'25", 800 ft north of highway bridge at The Weirs, 

Belknap County.

Drainage area. 363 sq mi at outlet at Lakeport.

Records available. November 1937 to September 1954 (month-end contents only for some 

periods , determined from gage at Lakeport, published in WSP 1301).

~"Gage. Water-stage recorder. Datum of gage is 600.02 ft above mean sea level, datum of 

Extremes . Maximum daily gage height during year, 5.86 ft May 22, 23; minimum daily, 2.04

1937-54: Maximum daily gage height, that of May 22, 23, 1954; minimum daily, 0.63 ft 

Dec. 11, 1941.

Remarks. Lake used for recreation and conservation for development of water power. Total 

usable capacity, 18,240,000,000 cu ft between elevations 494.55 ft (bottom of flume at 

Lakeport) and 504.22 ft (top of flashboards at outlet in Lakeport). Draft limited by 

law to an average of 250 cfs during the seven days in any week between June 1 and 

Oct. 15 of any year when gage reading is at or below 502.4 ft above mean sea level. 

Stage regulated at outlet and by Wentworth, Merrymeeting (see p. 112), and other lakes. 

Contents given herein are computed from gage height at 12 p.m. on last day of month, 

eliminating the effect of seiche and wind action.

Correction. --Daily gage heights were erroneously published in WSP 1271 as being midnight 

readings Instead of mean daily gage heights.

MERRIMACK RIVER BASIN 85

Lake Winnipesaukee Outlet at Lakeport, N. H.

Location. Lat 43°32'55", long 71°27'55", 100 ft upstream from highway bridge across 

Faugus 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 1954.

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, 1936, to 

May 23, 1944, discharge computed from flow over spillway and through gates and wheels 

at site 150 ft downstream.

Average discharge. 21 years, 535 cfs (adjusted for storage).

Extremes. Maximum daily discharge during year, 2,520 cfs June 2, 8; minimum daily, 150 

 c'fs Oct. 21.

1933-54: Maximum daily discharge, 2,890 cfs Mar. 31, 1936; minimum daily, 20 cfs 

Dec. 6-19, 1941, Dec. 22, 1941, to Jan. 19, 1942.

Remarks. Records good except those for periods of no deflection record, which are fair. 

Flow completely regulated by Winnipesaukee (see preceding page), Wentworth, Merrymeeting (see p. 112), and other lakes. Daily discharge computed from relation between 

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

Discharge, In cubic feet per second, water year October 1953 to September 1954

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 34 mi.

Records available. July 1903 to September 1954.

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

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

Average discharge. 49 years (1905-54), 2,801 cfs.

Extremes. Maximum discharge during year, 20,000 cfs May 11 (gage height, 15.18 ft); minimum daily, 258 cfs Oct. 24.

1903-54: 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 slope-area determination and computation of flow over dam at gage height 29.5 ft, and velocity-area 

study; minimum daily, 225 cfs Oct. 23, 1948.

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, Little 

Squam, Newfound, Winnipesaukee, Winnisquam, Wentworth, Merrymeeting, and other lakes. 

See pages 84,112 for description and monthly change in contents of many of these 

reservoirs.

Blackwater River near Webster, N. H.

Location. Lat 43°17'50", long 71°41'40", on left bank 0.2 mile west of Dingit Corner, 2f 

miles southeast of Webster, Merrimack County, and 6^ miles upstream from mouth.

Drainage area. 129 sq mi.

Records available.--May 1918 to September 1920, February 1927 to September 1954. Published as ''near Contoocook" 1918-20, 1927-35. Records published for both sites October 

1934 to September 1935.

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

Eb Oct. 1, 1934, chain gage at site 5 miles downstream at different datum. Both gages 

in operation Oct. 1, 1934, to Sept. 30, 1935.

Average discharge. 29 years (1918-20, 1927-54), 216 cfs (adjusted to present site).

Extremes. Maximum discharge during year, 2,100 cfs May 14 (gage height, 6.85 ft); minimum, 22 cfs Oct. 5, 6, 23-25, Apr. 8; minimum daily, 22 cfs Oct. 24.

1918-20, 1927-54: 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 slopearea 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 

or no gage-height record, which are good. High flow regulated by Blackwater Reservoir 

since 1941 (see p. 112). Some regulation at low flow by mill above station.

Revisions (water years).--WSP 696: Drainage area. WSP 821: 1936(M). WSP 851: 1936.

Natohaug River at Willimantio, Conn.

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

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

1 mile northeast of Willimantio, 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 1954.

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. 24 years, 299 cfs (adjusted for storage).

Extremes. Maximum discharge during year, 2,150 cfs Sept. 15 (gage height, 6.7 ft, from 

floodmarks); minimum, 5.9 cfs Aug. 25, 27, 28, 30 (gage height, 2.03 ft); minimum 

daily, 5.9 cfs Aug. 25, 28.

1930-54: Maximum discharge, 32,000 cfs Sept. 21, 1938 (gage height, 16.39 ft, from 

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

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

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

poor. City of Willimantic 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 cause diurnal fluctuation at low flow. Since March 1952, flow regulated 

by Mansfield Hollow Reservoir (see preceding page).

Average discharge. 25 years, 558 cf s .

Extremes . Maximum discharge during year, 8,990 cfs Sept. 12 (gage height, 12.77 ft); minimum, 10 cfs Oct. 24 (gage height, 1.59 ft); minimum daily 30 cfs Oct. 11.

1929-54: Maximum discharge, 20,900 cfs Sept. 21, 1938 (gage height, 19.45 ft, from 

floodmarks) , by computation of peak flow over dam 1 mile upstream and over dam on Little 

River 2 miles upstream from its mouth; minimum, 8.0 cfs Aug. 9, 1953 (gage height, 1.54 

ft); minimum daily, 11 cfs. Oct. 5, 12, 1930.

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

LTtTEle 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.

downstream from Deerfield River.

Drainage area. 7,865 sq mi.

Records available.--March 1904 to September 1954. Prior to October 1929, published as 

"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 

1929. Prior to Oct. 1, 1917, chain gage, Oct. I, 1917, to Oct. 8, 1921, water-stage 

recorder used for low stages, chain gage otherwise, and Oct. 9, 1921, to Oct. 29, 

1929, 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. 50 years, 13,770 cfs (adjusted for storage since October 1923).

Extremes.--Maximum discharge during year, 75,600 cfs Apr. 18 (gage height. 27 11 ft)- 

minimum daily, 385 cfs Oct. 4.

CONNECTICUT RIVER BASIN

Chicopee River at Indian Orchard, Mass.

Location. Lat 42°09'38", long 72°30'52", on left bank 1,000 ft downstream from West 

Street Bridge at Indian Orchard, Hampden County, and 1.1 miles upstream from Fuller 

Brook.

Drainage area. 688 sq mi.

Records available. August 1928 to September 1954. Published as "at Bircham Bend" prior 

to November 1938.

Gage. Water-stage recorder. Altitude of gage is 125 ft (from topographic map). Prior 

to Nov. 1, 1938, at site if miles downstream at different datum.

Average discharge.--26 years, 1,085 cfs (adjusted to present drainage area and for 

storage and diversions).

Extremes. Maximum discharge during year, 4,280 cfs Sept. 12 (gage height, 9.05 ft); minimum daily, 46 cfs Oct. 12.

1928-54: Maximum discharge, 45,200 cfs Sept. 21, 1938, by computation of flow over 

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

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

or backwater from aquatic vegetation, which are good. Diversion since 1941 from 186 

sq mi in Swift River basin and at times since 1931 from 97 sq mi 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 powerplants above station, by Quabbin Reservoir on Swift River since 1939 (see 

p. 233), and by smaller reservoirs.

Revisions (water years).--WSP 711: Drainage area. WSP 1231: 1934, 1939(M).

Gage. Water-stage recorder and concrete control. Datum of gage is 461.25 ft above mean 

sea level, datum of 1929 (levels by Corps of Engineers). Prior to Jan. 11, 1935, chain 

gage at site 0.5 mile upstream at different datum. Jan. 11, 1935, to May 20, 1940, 

water-stage recorder at site 700 ft upstream at datum 10.57 ft higher. May 21 to 

Dec. 19, 1940, staff gage at site 700 ft upstream at datum 18.75 ft higher.

Average discharge. 45 years, 322 cfs (adjusted for storage).

Extremes.--Maximum discharge during year, 3,330 cfs Apr. 20 (gage height, 5.97 ft); minimum, 8.0 cfs Mar. 4; minimum daily, 10 cfs Oct. 3, 4.

1909-54: Maximum discharge, 37,900 cfs Sept. 21, 1938 (gage height, 29.58 ft, from 

floodmarks, site and datum then in use), from rating curve extended above 3,800 cfs on 

basis of slope-area determinations at gage heights 24.07 and 29.58 ft; minimum, 0.6 cfs 

Aug. 11, 1941; minimum daily, 4 cfs Aug. 10, 1913.

Remarks. Records excellent except those for periods of no gage-height record or shifting 

control, which are good. Flow regulated by Knightville Reservoir since 1941 (see 

p. 233).

MENUNKETESUCK RIVER BASIN 

Menunk'etesuck River near Clinton, Conn.

235

Location.--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 1954.

3.--W 

T929. "19"" Gage. Water-stage recorder. Datum of gage is 23.64 ft above mean sea level, datum of 

Average discharge. 13 years, 21.7 cfs (adjusted).

Extremes (unadjusted for storage or diversion). Maximum discharge during year, 1,600 cfs 

Sept. 11 (gage height, 8.51 ft), from rating curve extended above 270 cfs on basis of 

computation of peak flow over Kelseytown Dam; minimum discharge, 0.004 cfs Oct. 6 

(gage height, 0.63 ft).

1941-54: Maximum discharge, that of Sept. 11, 1954; no flow at times during August 

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

Remarks. Records good except those for periods of backwater from rocks and those below 

2.0 cfs, which are fair. 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 milss 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. 1-27, June 6 to Aug. 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.

HOUSATONIC RIVER BASIN 345

Shepaug River at Woodville, Conn.

Location. Lat 41°43'24", long 73°17'37", at left end of dam at outlet of Shepaug Reservolr, 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 1954.

Gage. Nonrecording gage read usually once daily.

Average discharge. 19 years, 84.6 cfs (adjusted for storage and diversion).

Extremes. Maximum discharge during year from graph based on gage readings, 800 cfs 

Apr. 17; no flow at times.

1935-54: 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. Flow regulated since 

September 1933 by Shepaug Reservoir (see p. 253).

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

Revisions (water years).--WSP 971; 1936-42. WSP 1231: 1937(M), 1940(M), 1941(M),

MISCELLANEOUS DISCHARGE MEASUREMENTS 255

Measurements of streamflow in the North Atlantic slope basins, Maine to Connecticut, 

made at points other than regular gaging 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 continuous records are available will give a picture of 

the low-flow potentiality of stream. For many sites measurements have been made in other 

years.
