SURFACE WATER SUPPLY OF NORTH ATLANTIC SLOPE BASINS, 1941

SCOPE OF WORK

This volume is one of a series of 14 reports presenting results of measurements of 

stage and flow made on streams, lakes, and reservoirs in the United States during the 

water year ending September 30, 1941. The work was begun In 1888 In connection with 

special studies relating to Irrigation. Measurements of the flow of streams and of the 

stage and contents of lakes and reservoirs have been made at about 9,120 gaging stations 

In the United States and also at many gaging stations In Alaska and Hawaii. In July 1941, 

4,850 gaging stations were being maintained by the Geological Survey and cooperating organizations. Miscellaneous discharge measurements were made at many other points.

In the execution of the work many State and private organizations have cooperated, 

either by furnishing data or by assisting in collecting data. Cooperation of the first 

kind Is acknowledged In connection with the description of each station affected; cooperation or the second kind Is acknowledged on page 10.

DEFINITION OF TERMS

The units In which stream-flow data are presented In this report and other terms used 

herein are defined as follows:

"Second-feet" la an abbreviation for "cubic feet per second." A second-foot 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.

"Second-feet per square mile" is the average number of cubic 'feet of water flowing per 

second from each square mile of area drained, on the assumption that the runoff Is distributed uniformly both as regards 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. It Is used 

for comparing runoff with rainfall, which Is usually expressed In Inches.

An "acre-foot" Is the quantity of water required to cover an acre to the depth of 1 

foot and is equivalent to 43,560 CUDIC reet. The term Is commonly used In connection-with 

storage for Irrigation.

"Second-foot-day" Is the volume of water represented by a flow of 1 second-foot 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 an abbreviation for the term "relation between gage 

height and discharge."

"Control" Is a term used to designate a feature downstream from the gage that determines 

the stage-discharge relation at the gage. This feature may be a natural section, a reach 

of the channel, or an artificial structure.

EXPLANATION OF DATA

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

discharge, and general information used to supplement the records of stage and discharge

1
- 2 EXPLAMTION OF DATA

measurements 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 Rives a continuous record of the fluctuations. Measurements of discharge are made with a current 

meter by the general methods outlined in standard textbooks on the measurement of river 

discharge. Typical structures In use at gaging stations are shown on plate 1.

Rating tables giving the discharge for any stage are prepared from the discharge measurements. The application oi the daily mean gage height to these 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 tnat form the control, the dally mean discharge is 

determined by the "shifting-control method," in which correction factors based on Indivldu 

al discharge measurements are used in applying the gage heights to the rating tables.

At some gaging stations the stage-discharge relation is affected by backwater from 

reservoirs, tributary streams, or other sources, which necessitates the use of the "slope 

method" in which the slope or fall In a reach of the stream is a factor In the determination of discharge. Information requisite for determining the slope or fall is obtalnsd 

by means of an auxiliary gage set at some distance from the base gage. At some stations 

the stage-discharge relation is affected by changing stage, and for them 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, which makes It 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 stations in the same or nearby basins. The days 

included in the periods of Ice effect and the days during the winter period on which discharge measurements were made are indicated in the table by symbols referring to footnotes.

For most of the gaging stations on streams in the area covered by this report the data 

presented comprise a deecriptlon of the station, a table showing the dally discharge of 

the 3tream, and a table of monthly and yearly discharge and runoff. Skeleton rating 

tables are published for all stations except those at which the dally discharge for the 

greater part of the year was determined by the shifting-control method, the slope method, 

or other special methods.

The description of the station gives the type of gage, Its latitude and longitude 

determined from the best available maps, and Information In regard to diversions that 

decrease the flow at the gage, artificial regulation from ponaage or storage, and the 

accuracy of the records.- Under "Average discharge" Is given the average discharge for the 

number of years indicated. It Is given only for stations for which there are 10 or more 

complete years of record. Under "Extremes" are given the maximum discharge and gage 

height; the minimum discharge if there is little or no regulation; the minimum dally 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 or a nonrecordlng gage read at the time of the crest. Likewise the minimum discharge represents the lowest stage, unless otherwise qualified. Selected peak discharges 

with the times of their occurrence are given below the table of monthly discharge for some 

stations. This supplementary information Is generally omitted for stations having drainage areas of less than 10 square miles or more than 10,000 square miles or if the peak 

discharges usually exceed the corresponding mean discharges for the day by less than 10 

percent.

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

the discharge in second-feet corresponding to once-daily readings of the gage or the mean 

of twice-daily readings. For flashy floods the dally mean discharge is determined from 

gage-height graphs based on gage readings made once or twice daily or oftener, as stated 

in the station description. For stations equipped with water-stage recorders, except those 

on streams subject to sudden or rapid fluctuation, the table gives the discharge corresponding to the daily mean gage height. For stations subject to such fluctuation the 

dally 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 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.

In the table of monthly discharge the column headed "Second-foot-days" gives the sum 

for each month of the figures given in the table of dally discharge. The column headed 

"Maximum" gives the maximum daily discharge and not the momentary discharge when the 

water surface ,was at crest stage. Likewise, in the column headed "Minimum" the quantity 

given Is the minimum dally discharge. The column headed "Mean" gives the average flow 

In cubic feet per second during the month.

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 a few of the 

more Important lakes and reservoirs a table showing daily contents is given. A skeleton 

table of capacity at given stages is usually given In the first report in which data for 

a station are published but is omitted from succeeding reports.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS ,

The accuracy of stream-flow data depends primarily on (1) the permanency of the stagedischarge relation and (2) the accuracy of observations of stage, measurements of flow, and 

interpretation of records.

The station description gives a statement in regard to the general accuracy of the 

records. "Excellent" Indicates that, in general, the daily records are accurate within 

5 percent; "good," within 10 percent; "fair," within 15 percent; and "poor," within 20 or 

a higher percent.

Yield at some stations as indicated by monthly means may vary widely from natural yield, 

owing to diversion, consumption, regulation by storage, increase or decrease in evaporation due to artificial causes, or other factors. For such stations figures of "secondfeet per square mile" and "runoff in inches" are not published unless storage or diversion 

records are included Indicating the extent of the regulation or diversion or unless
4 ACCURACY OF FIELD DATA AND COMPUTED RESULTS

satisfactory adjustments can be made for changes In contents of reservoirs or for other 

changes incident to use and control. Figures of second-feet per square mile and runoff 

in inches are also omitted if the drainage area Includes large noncontributing areas or 

if the average annual rainfall over the drainage area Is less than 20 Inches.

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 show the water supply available for further development, as prior appropriations 

below the station must first be satisfied.

The table of monthly discharge presents in summary the distribution of the flow past 

the station. The table of dally discharge affords opportunity for more detailed studies 

of the variation in flow. As further observations In each succeeding year may be expected 

to throw new light on data previously published, it should be borne in mind that such data 

are subject to revision in succeeding water-supply papers.

in the area covered by part 3 are published In Water-Supply papers 283, 303, 323, 353, 

403, 433, 463, 473, 503, which contain records for the Ohio River Basin for those years.

The records at most of the stations discussed In these reports extend over a series of 

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 listed appearing in the same 

relative order as the streams and gaging stations In the body of the report. An Index of 

the records obtained prior to 1904 has been published In Water-Supply Paper 119.

Each of the reports on surface water supply for the year 1939, issued as Water-Supply 

Papers 871 to 884 (see table on p. 6), contains a summary of yearly discharge at gaging 

stations In the area covered by that report. Gaging stations at which 10 or more complete years of record have been collected are represented. These summaries are available 

also as separate reprints.

From tine to time reports have been published that are compilations of records for 

various areas, usually a single State or drainage basin. These reports contain records 

previously publisned (some of which nave been revised), as well as some recoras not contained in the annual series of water-supply papers. The following table gives the numbers and titles of these reports, arranged In alphabetical order by States and drainage 

basins.

g Computed from graph based on reference gage reading.

Mote.- No gage-height record Jan. 18 to Feb. 11, July 12-17, 24-30, Aug. 5, 6; discharge interpolated or computed on basis of recorded range of stage, weather records, and records for Mother 

Brook at Dedham. Probably some backwater from ice during period of no gage-height record in February.
100 CHARLES RIVER BASIN

Charles River at Waltham, Mass.

Location.- Water-stage recorder, lat. 42°22'20M , long. 71°14'05", 600 feet downstream

from Clematis Brook. Datum of gage is 20.02 feet above mean sea level, datum of 1929.

Drainage area.- 227 square miles (not including i>3.6 square miles drained by Stony Brook, 

run-orr from which is diverted for municipal supply of Cambridge).

Records available.- October 1903 to October 1909 (figures of average weekly discharge, 

equivalent to figures of unadjusted discharge at present site), August 1931 to 

September 1941.

Average discharge.- 10 years, 383 second-feet (adjusted for wastage and diversion).

Extremes.- Maximum discharge during year, 555 second-feet Feb. 15; maximum gage height, 

2.42 Teet (regulated) Nov. 22: minimum discharge, 2.5 second-feet (regulated) Oct. 

26-29 (gage height, 0.40 foot).

1931-41: Maximum discharge, 2,540 second-feet Mar. 19, 1936 (gage height, 4.79 

feet); minimum, 0.9 second-foot (regulated) Aug. 24-26, 1936 (gage height, 0.39 foot).

Remarks.- Records good except those for periods of Ice effect or backwater from debris, 

which are fair. Flow affected by wastage from Stony Brook Reservoir and pressure 

aqueduct of Metropolitan District Water Supply Commission, diversions to Mother Brook, 

and diversions for municipal supplies of Wellesley, Needham, Dedham, Brookline, Newton, 

and Waltham, all above station. Low flow completely regulated by the Boston Edison 

Co.power riant above station.

* Winter discharge measurement made on this day.

b Stage-discharge relation affected by Ice.

Note«- Backwater from rocks on control July 21 to Sept. 30; discharge computed on basis of four 

discharge measurements, engineers' notes and records for Wllllmantlc River near South Coventry, 

Sbetucket River near Wllllmantlc, and Natcuaug River at Wllllmantlc.
THAMES RIVER BASIN 123

Natchaug River at Willimantic, Conn.

Location.- Water-stage recorder, lat. 41°43'14", long. 72°11'53", 200 feet downstream from 

Hew York, New Haven & Hartford Railroad bridge, 1 mile northeast of Willlmantlc. Wlndham 

County, and It miles upstream from mouth. Datum of gage Is 150.31 feet above mean sea 

level, datum of 1929.

Drainage area.- 169 square miles.

Records available.- October 1930 to September 1941.

Average aischarge?- 11 years, 316 second-feet.

Extremes.- naxlmul discharge during year, 4,790 second-feet Feb. 8 (gage height. 10.25 

feet); minimum, 3.2 second-feet (regulated) sept. 17 (gage height, 1.47 feet); minimum 

dally, 3.3 second-feet (regulated) Sept. 17, IS.

1930-41: Maximum discharge, 32,000 second-feet Sept. 21, 1938 (gage height, 16.39 

feet, from floodmarks), by computation of flow over dam 2 miles above station; minimum, 

about 0.3 second-foot (regulated) Aug. 6, 1937; minimum dally, 2.9 second-feet (regulated) Aug. 6, 1937.

Remarks.- Records excellent except those for periods of Ice effect, which are fair. City 

or willlmantlc diverts an average of about a million gallons of water a day for municipal 

supply from reservoir 2 miles above station. Operation of water wheels causes diurnal 

fluctuation during low flow.

Note.- Backwater from aquatic growth Oct. 1 to Nov. 1, May 8 to Sept. 30; discharge computed on 

basis of seven discharge measurements and records for stations at Putnara and Jewett City.
THAMES RIVER BASIN 

Qulnebaug River at Putnam, Conn.

127

Location.- Water-stage recorder, lat. 41°54'30", long. 71°54'30n , at Putnam, Windham 

County, 600 feet downstream from Muddy Brook (Little River) and 3 miles downstream 

from French River.

Drainage area.- 331 square miles.

Records available.- December 1929 to September 1941.

Average discharge.- 12 years, 574 second-feet.

Extremes^- Maximum discharge during year, 2,790 second-feet Feb. 8 (gage height, 7.49 

reet/y minimum, 18 second-feet (regulated) Sept. 28 (gage height, 1.66 fe£t); minimum dally, 30 second-feet (regulated) Sept; 29.

1929-41: Maximum discharge, 20,900 second-feet Sept. 21, 1938 (gage height, 

19.45 feet, from floodmarks), by computation of flow over dam 1 mile upstream and 

over dam on Muddy Brook (Little River) 2 miles upstream from its mouth; minimum. 8.5 

second-feet (regulated) Oct. 26, 1935; minimum daily, 11 second-feet (regulated) 

Oct. 5, 12, 1930.

Remarks.- Records excellent. Large diurnal fluctuation, particularly during low water, 

is caused by operation of many dams and reservoirs; largest reservoir in the headwaters Is Lake Chaubunagungamaug with an estimated usable capacity of 207,000,000 

cubic feet.

Winter discharge measurement made on this day.

a No gage-height record; discharge computed on basis of one discharge measurement, weather records, 

and records for stations on nearby streams.

Note.- Stage-discharge relation affected by ice Nov. 26-29, Dec. 2-4, 9-30, Jan. 15 to Feb. 8, Feb. 

15 to Bar. 15, Mar. 18-23; probably affected by Ice during part of period of no gage-height record.
CONNECTICUT RIVER BASIN 

Ashuelot River near Gilsum, N. H.

169

Location.- Water-stage recorder, lat. 43°02'20", long. 720 16'15", at stone-arch bridge 

just off Keene-Newport road, 0.7 mile downstream from Gilsum, Cheshire County. Datum 

of gage is 773.86 feet above mean sea level (levels by Corps or Engineers, U. S. 

Army).

Drainage area.- 71.1 square miles.

Records available.- August 1922 to September 1941.

Average discharge.- 19 years, 125 second-feet.

Extremes.- Maximum gage height during year, 5.18 feet Feb. 9, affected by ice (discharge 

not determined); minimum discharge, 5.7 second-feet Sept. 27.

1922-41: Maximum discharge, 5,220 second-feet Sept. 21, 1938 (gage height, 11.24 

feet), from rating curve extended above 2,000 second-feet on b»sis of float measurements and slope-area computation at gage height 11.24 feet; minimum, about 1 secondfoot (regulated) Oct. 6, 1922, July 10, 1923.

Remarks.- Records good except those for periods of Ice effect, which are fair, and those 

for periods of no gage-height record, which are poor. Flow regulated by reservoir 

above gage. Slight diurnal fluctuation caused by power plant above gage.

Rating table water year 1940-41, except periods of ice effect (gage height, 

in feet, and discharge, in second-feet)

feet above mean sea level, datum of 1929.

Drainage area.- 497 square miles. * 

Itecords ^available.- June 1914 to September 1941.

Average discharge.- 27 years, 917 second-feet (adjusted for diversion since 1914 and for 

change^ in reservoir contents since Oct. 1, 1931).

Extremes.- Maximum discharge during year. 7,730 second-feet Feb. 8 (gage height, 10.85 

reetj; minimum, 77 second-feet (regulated) Oct. 27, 28; minimum dally, 81 second-feet 

Oct. 27, 28.

1914-41: Maximum discharge, 55,500 second-feet Sept. 21, 22, 1938 (gage height, 29.40 

feet, from floodmarks), from rating curve extended above 18,000 second-feet on basis of 

computation of flow over dams at gage heights 27.20 feet and 29.40 feet; minimum, 9 

second-feet (regulated) Oct. 2, 1921.

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

wnich are fair. Diurnal fluctuation at low stages caused by power plants above station. 

Flow regulated by diversion from Westfleld Little River for municipal supply of 

Springfield, and by Borden Brook and Cobble Mountain Reservoirs (see p.144 ).

of three discharge measurements, engineer's notes, and records for stations on North Branch of Park 

River and Park River at Hartford.
204 CONNECTICUT RIVER BASIN

Park River at Hartford, Conn.

Location.- Water-stage recorder above spillway of timber dam, lat. 41°45'36", long. , 

72-41 '42", at plate-girder footbridge on Riverside Street, In Hartford, Hartford 

County, 1,300 feet downstream from confluence of North and South Branches and 2.3 

miles upstream from mouth. Datum of gage Is 27.13 feet above mean sea level, datum 

of 1929.

Drainage area.- 74.0 square miles.

Records available.- October 1936 to September 1941.

Extremes.- Maximum discharge during year, 2,960 second-feet Feb. 8 (gage height, 7.20 

reet); minimum, 11 second-fset Sept. 29; minimum dally, 12 second-feet Sept. 29; 

minimum gage height, 2.03 feet Apr. 18 (pool level lowered by opening In control). 

1936-41: Maximum discharge, 5,650 seccnd-feet Jan. 25, 1938 (gage height, 9.16 

feet); minimum, about 4 second-feet (regulated) Sept. 23, 1937; minimum dally, that 

of Sept. 29, 1941; minimum gage height, 1.83 feet June 11, 12, July 6, 1939 (pool level 

lowered by openings In control).

Flood of Mar. 12, 1936, reached a stage of 9.0 feet, as determined from floodmarks 

by city engineers of Hartford (discharge, 5,400 second-feet). A stage of 10.7 feet 

from floodmarks was caused Mar. 21, 1936, by backwater from Connecticut River.

Remarks.- Records good for medium and high stages and for low stages not affected by backwater from Ice or debris on control; other records fair. Slight dlumal fluctuation 

during low flow.

reet downstream from stone-arch bridge on Albany Avenue, Hartford, Hartford County, 

and 3 nlles upstream from confluence with South Branch. Datum of gage is 34.20 feet 

above mean sea level, datum of 1929.

Drainage area.- 25.3 square -".lies.

Records available.- October 1936 to September 1941.

Extrerr.es.- Maximum discharge during year, about 800 second-feet Feb. 8; maximum gage 

neignt, 8.98 reet, Feb. 8, Ice jam; minimum discharge, 0.06 second-foot Sept. 28 

(gage height, 0.76 foot); minimum daily, 0.08 second-foot Sept. 28.

1935-41: Maximum discharge, 1,640 second-feet Jan. 25, 1938 (gage height, 11.6 

feet), from rating curve extended above 300 second-feet by logarithmic plotting; 

minimum, that of Sept. 28; minimum daily, that of Sept. 28.

Flood of Mar. 12, 1936, reached a stage of 11.2 feet, as determined by city engineers of Hartford, from floodmarks (discharge, probably 1,520 second-feet, from current 

rating curve after adjusting observed gage height to equivalent gage height for present 

conditions).

Remarks.- Records good except those for periods of ice effect, backwater from rocks or 

trash on control, or doubtful gage-height record, which are fair. Infrequent low-water 

regulation by small mills above station.

206 CONNECTICUT RIVER BASIN

Hoekanum River near East Hartford, Conn.

Location.- Water-stage recorder, lat. 41°46'57", long. 72°35'20", a short distance downstream from dam at Case & Marshall paper mill, li miles downstream from South Branch, 

and 2f miles east of East Hartford, Hartford County. Datum of gage is 54.5 feet above 

mean sea level, datum of 1929 (levels by Department of Engineering, city of Hartford).

Drainage area.- 74.5 square miles.

Records available.- September 1919 to September 1921, July 1923 to September 1941.

Average discharge.- 15 years, 117 second-feet.

Extremes.- Maximum discharge during year, 1,690 second-feet Feb. 8 (gage height, 8.16 

feet); minimim, 3.2 second-feet (regulated) Sept. 1 (gage height, 0.85 foot); minimum 

daily, 3.7 second-feet (regulated) Sept. 1.

1S19-21, 1928-41: Maximum discharge, 5,160 second-feet Sept. 21, 1938 (gage height, 

IS.78 feet, from floodmark), by computation of flow over dam just above gage; practically no flow at times caused by regulation; minimum daily, 1.2 second-feet Sept. 2, 1920.

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

flow regulated by Shenipsit Lake (total capacity, 4,700,000,000 cubic feet) and other 

smaller reservoirs above station.

216 HOUSATONIC RIVER BASIN

Housatonic River at Stevenson, Conn.

Location.- Water-stage recorder, lat. 41 023'05", long. 73009 l 55n , in New Haven County, a 

quarter of a mile upstream from Eightmile Brook and a quarter of a mile downstream 

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

gage Is 24.98 feet above mean sea level, datum of 1929.

Drainage area.- 1,545 square mile's.

Records available.- August 1928 to September 1941.

Average dlscnargeT- 13 years, 2,490 second-feet (unadjusted prior to 1936).

Extremes.- Maximum discharge during year, 30.500 second-feet Feb. 8 (gage height, 15.55 

feet;; minimum, 51 second-feet (regulated) Sept. 29 (gage height, 0.59 foot); minimum 

daily, 89 second-feet (regulated) July. 27.

1928-41: Maximum discharge, 69,500 second-feet Mar. 12, 1936 (gage height, 23.5 

feet, from floodmarks), by computations of peak flow at Stevenson and Derby Dams and 

slope-area determination at gaging station; practically no flow at times, result of 

regulation.

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

record, which are fair. Ordinary flow completely regulated at Stevenson hydro-electric 

plant. Flow regulated by Rocky River, Stevenson, and Shepaug Reservoirs (combined 

usable capacity, 6,600,000,000 cubic feet), and by slight diversion from the basin at 

Shepaug Reservoir.

toe of dam. Rating curves for floodgates and fountain computed by rueans of a temporary 

sharp-crested weir below dam. Rating curve for spillway computed for discharges below 

16.5 second-feet by means of sane weir and for discharges above 18.5 second-feet by a 

formula selected to fit the spillway-crest sections. At times of ice effect on spillway, flow computed from ;age-readings at a permanent artificial control Lelow dam, 

which v.as calibrated with the sharp-crested weir prior to its removal. Gages at dam 

or artificial control read once daily, oftener rturinfe periods of extremely high flow. 

Water diverted from Shepaug Reservoir for Tunlclpal supply of Waterbury. Flow regulated 

by Shepaug Reservoir (capacity ye,000,000 cubic feet).

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

 October 1885 arid June to October 1903 (fragmentary) in Professional Paper 44 of 

Geological Survey, and January 1937 to September 1941 in water-supply papers of 

Geological Survey. June to October 1903 in report of New York State engineer and surveyor for 1904,

Extremes.- Maximum gage height during year, 3.15 feet,Feb. 8 from high-water mark in gage

 House (discharge not determined), affected by backwater from Freeport Pond; minimum 

discharge, 6.10 second-feet Sept. 27 (gage height, 0.302 foot).

1903, 1937-41: Maximum gage height, that of Feb. 8, 1941; minimum, that of Sept. 27, 

1941.

An average discharge of 6.54 second-feet was recorded for the period Sept. 19 to 

Oct. 2, 1685.

Remarks.- Records excellent except those tor periods of backwater from Freeport Pond or 

doubtful gage-height record, which are fair, and those for period o'f fragmentary gageheight record, which are poor. This station Is being operated in connection with an 

Inventory of ground-water resources on Long island, in addition to records of stream 

flow, .records of ground-water levels are being collected. Records for 1941 are published 

in Water-Supply Paper 936.

bare rage.

Records available.- May 1927 to September 1041.

Remarks.- Records food except those for periods of fragmentary or no gage-height record, 

which are fair. Daily discharge determined by use of Chezy formula, variations in 

coefficient C throughout the season being computed from current-meter measurenents. 

Flow regulated in accordance with requirements of Champlain Canal and for floating 

logs. Operation of feeder discontinued Nov. 29 and resumed Apr. 24. During period 

for which no diversion is shown the feeder say carry a small flow representing 

leakage through tile head gates and run-off from area tributary to feeder above

'(estimated) Jan. 17, 1931.

Reports of State engineer and surveyor record a maximum discharge of 4,210 secondfeet Mar. 9, 1921.

Remarks.- Records excellent. During navigation season water is diverted from Black River 

through Forestport feeder and Black River Canal (flowing south) into Delta Reservoir 

above station. Flow is almost completely regulated by Delta Reservoir (capacity, 

2,800,000,000 cubic feet). A small quantity of water is diverted from Delta Reservoir 

for use of fish hatchery and later returned to the river, part of it above and part 

below gage.

Note.- Elevation of water surface in Delta Reservoir; 539.45 feet at midnight Sept. 30, 1940; 

539.85 feet at midnight Sept. 30, 1941; 530.55 feet at midnight Dec. 31, 1939; 551.25 feet at midnight Dec, 31, 1940.
HUDSON RIVER BASIN 257

Mohawk River near Little Falls, N. Y.

Location.- Water-stage recorder, lat. 43°00'50", long. 74°46'40It , 1,800 feet downstream 

from Rocky Rift Dam, 2 miles upstream from East Canada Creek, and 4i miles southeast 

of city of Little Falls, Herklmer County. Datum of gage is 310.0 feet above mean sea 

level (Barge Canal datum).

Drainage area.- 1,348 square miles.

Kecoras available.- February to April 1901, October 1927 to September 1941. November 

1923 to September 1927 in files of State Department of Public Works.

Average discharge.- 14 years (1927-41), 2,681 seccnd-feet.

axtreines.- naximum discharge during year (river channel only), 20,200 second-feet Dec. 29 

(gage neight, 15.91 feet); minimum (river channel only), 375 second-feet (regulated) 

Aug. 10 (gage height, 4.15 feet); minimum daily (including canal), 507 second-feet 

(regulated) Aug. 10.

1927-41: Maximum discharge (river channel only), 23,200 second-feet Mar. IS, 1936 

(gage height, 17.24 feet), from rating curve extended above 13,600 second-feet by 

logarithmic plotting; minimum (river channel only), probably not less than 305 secondfeet Aug. 8, 1933 (gage height, 4.09 feet); tniniiium daily (Including canal), probably 

not less than 463 second-feet Sept. 2, 1934.

Remarks.- Records excellent except those for periods of ice effect and periods of doubtful 

or no gage-height record, which are fair. Records of daily discharge include diversion 

of water at Rocky Rift Dam into Barge Canal for power and lockage at lock 16, near St. 

Johnsville. During canal navigation season, water is received from Black River through 

Black River Canal (flowing south) and Lansing Kill, and possibly from Chenango River 

Basin through Oriskany Creek feeder. Water is diverted into (or may occasionally be 

received from) Oswego River Basin through summit level of Earge Canal near Rome. 

Diurnal fluctuation caused by power plants and locks and dams on Barge Canal. Flow 

partly regulated by Delta and Hinckley Reservoirs (combined capacity, 6,120,000,000 

cubic feet).

258 HUDSON RIVER BASIN

Mohawk River at Cohoes, N. Y.

Location.- Water-stage recorder, lat. 42047'05lt , long. 73°42'2511 , at School Street plant 

of New York Power & Light Corporation In Cohoes, Albany County.

Drainage area.-' 3,456 square miles.

Records available.- July to October 1925 (computed from records at dam and School Street 

plant or Hew York Power & Light Corporation) and October 1925 to September 1941. 

December 1917 to July 1925 at Crescent Dam, 2 miles upstream.

Average discharge.- 23 years (1918-41), 5,591 second-feet.

Extremes.- Maximum discharge during year, 49,100 second-feet Dec. 30 (gage height, 17.18 

feet); minimum, 6 second-feet (regulated) Sept. 28 (gage height, 3.40 feet); minimum 

daily, 23 second-feet Aug. 24.

1925-41: Maximum discharge, 130,000 second-feet Mar. 19, 1936 (gage height, 22.57 

feet), from rating curve extended above 34,500 second-feet by logarithmic plotting; 

minimum, that of Sept. 28, 1941; minimum daily, that of Aug. 24, 1941.

Remarks.- Records excellent except those for period of doubtful gage-height record, which 

are good. Discharge includes small diversion just above gage for Cohoes water supply, 

but does not include diversion through lock 6 at Crescent Dam (published herewith) 

for operation of Barge Canal. During canal navigation season, water is received from 

Black River through Black River Canal (flowing south) and Lansing Kill, and possibly 

from Chenango River Basin through Oriskany Creek feeder. Water is diverted Into (or 

may occasionally be received from) Oswego River Basin through summit level of Barge 

Canal near Rome. Most of the flow of Schoharie Creek, a tributary of Mohawk River, 

Is diverted out of basin through Shandaicen tunnel for New York City water supply. Flow 

partly regulated by storage, principally in Delta, Hinckley, and Gllboa Reservoirs 

(combined capacity, 8,738,000,000 cubic feet). Diurnal fluctuation caused by School 

Street power plant.

Location.- Water-stage recorder, lat. 43°04 I 15", long. 74°59'25", 600 feet downstream 

from highway bridge at Kast Bridge station on Hew York Central Railroad, Herkimer 

County, and 4 miles upstream from mouth and Herkimer.

Drainage area.- 556 square miles.

Records available.- May 1905 to December 1909 (1905-6, gage heights and discharge measurements only), January 1912 to December 1913 and October 1920 to September 1941 in reports 

of Geological Survey. January 1910 to Decenber 1911 and January 1914 to September 1920 

in reports of State engineer and surveyor.

Average discharge.- 21 years (1920-41), 1,319 second-feet.

"Extremes.- Maximum discharge during year, 12.600 second-feet Dec. 29 (gage height, 6.37 

feet); minimum, 55 second-feet (regulated) Aug. 9 (gage height, 0.97 foot); minimum 

daily, 202 second-feet Aug. 9.

1920-41: Maximum discharge, 16,500 second-feet June 21, 1922 (gage height, 7.3 

feet), from rating curve extended above 9,000 second-feet; minimum, 20 second-feet 

Sept. 3, 1929 (gage height, 0.90 foot); minimum daily, 59 second-feet Sept. 2, 1929. 

Maximum discharge known, 23,300 second-feet Mar. 26, 1913, fron reports of State 

engineer and surveyor.

Remarks.- Records excellent except those for periods of ice effect or fragmentary gageheight record, which are fair. Flow partly regulated by HlncKley Reservoir (capacity, 

3,320,000,000 cubic feet). Diurnal fluctuation at low and nedium stages caused by 

power plant above station. During canal navigation season Ilinemile feeder diverts 

from West Canada Creek at Trenton Falls.

262 HUDSON RIVER BASIN

Ninemile feeder near Holland Patent, N. Y.

Location.- Water-stage recorder and concrete control, lat. 43°13'25", long. 75°12'15", 

at mouth of feeder, half a mile downstream from highway bridge that is 3 miles east 

of Holland Patent, Oneida County, and 6 miles downstream from Intake.

Records available.- June 1919 to September 1941 (navigation seasons only).

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

or backwater from debris on control, and those below 100 second-feet, all of which 

are good. Canal diverts from West Canada Creek at Trenton Falls. Water reaches 

Barge Canal through Ninemile Creek. Discharges shown subsequent to the discontinuance 

of diversion on Nov. 15 and prior to the resumption of diversion on Apr. 28 are madB 

up of channel storage, leakage through the head gates, and run-off frori the area 

tributary to feeder above station. This flow nay continue during period of no record.

in reports of State engineer and surveyor.

Average discharge.- 14 years (1927-41), 630 second-feet.

Extremes.- Maximum discharge during year, 9,480 second-feet Sept. 1 (gage height, 10.97 

feet); minimum, about 4 second-feet (regulated) July 26, Aug. 8-14, 24 (gage height, 

5.38 feet); minimum daily, 20 second-feet Aug. 11, 14.

1927-41: Maximum discharge, 13,100 second-feet Mar. 18, 1936 (gage height, 11.81 

'feet), from computation of peak flow over dams at Inghams and Beardslee Falls hydroelectric plants; minimum, about 4 second-feet frequently when plant is shut down and 

there Is no spillage; minimum daily, that of Aug. 11, 14, 1941.

Maximum discharge known, 14,500 second-feet Mar. 26, 1913, from reports of State 

engineer and surveyor.

Remarks.- Records good except those for periods of Ice effect or fragmentary gage-height 

record, which are fair. City of Little Falls diverts about 5 second-feet for municipal supply. Slight regulation by Canada Lakes (capacity, about 441,000,000 cubic 

feet). Diurnal fluctuation at low and medium stages caused by power plant above station.

T Adjusted for change in contents in Farrington Reservoir,
326 RARITAN RIVER BASIN

South River at Old Bridge, N. J.

Location.- Water-stage recorder above Duhemal Dam, lat. 40°24'09", long. 74°21'58", 1,500 

feet downstream from Ireslck BrooK and 0.6 mile south of Old Bridge, Middlesex County. 

Datum of gage Is at mean sea level, datum of 1929.

Drainage area.- 34.6 square miles.

hecoras available.- August 1939 to September 1941.

extremes.- Maximum discharge during year, 1,380 second-feet July 5 (gage height, 10.81 

feet;, from rating curve extended above 700 second-feet on basis of laboratory rating; 

minimum, 19.3 second-feet Sept. 19-21 (gage height, 9.50 feet).

1939-41: Maximum discharge, that of July 5, 1941; minimum, that of Sept. 19-21, 1941.

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

BuKernal Dam, constructed In 1939, forms a pond to supply ground water to be pumped from 

nearby wells constructed at the same time. Records of pumpage from these wells and runoff in the river, studied In the light of run-off In nearby streams, indicate that beginning with April, the flow in the river was diminished by the full amount of the water 

pumped. Prior to April the water pumped from these wells probably was drawn from ground 

storage, rather than from infiltration from the pond.

Cooperation.- Water-stage recorder Inspected by an employee of E. I. du Pont de Nemours

Remarks.- Records excellent except those for periods of ice effect or of fragmentary or 

doubtful gage-height record, which are good. Large diurnal fluctuations at medium and 

low stages caused by power plants on tributary streams. Flow regulated considerably 

by Lake Wallenpaupack and Toronto, Cliff Lake and Swinging Bridge Reservoirs (combined 

capacity, 12,300,000,000 cubic feet).

Cooperation.- Records of storage furnished by Pennsylvania Power and Light Co. for Lake 

wallenpaurack, and by Rockland Light and Power Co. for Toronto, Cliff Lake and Swinging

Cold Spring Brook at China, N. Y.

Location.- Water-stage recorder and concrete control with V-notch weir, lat. 42°09'35", 

long. 75°23'35", 1 mile upstream from China and 2 miles west of Upper Barbourvllle, 

Delaware County. Datum of gage Is 1,490.76 feet above mean sea level, adjustment 

of 1912 (levels by Corps of Engineers, U. S. Army).

Records available.- October 1934 to September 1941.

Extremes.- Maximum discharge during year, 46 second-feet Doc. 29 (gage height, 3.08 feet); 

minimum, 0.018 second-foot July 27 (gage height, 1.125 feet).

1934-41: Maximum discharge, 335 second-feet Oct. 30, 1935 (gage height, 4.5 feet, 

from floodmarKs), from rating curve extended above 54.7 second-feet on basis of 

theoretical rating; minimum, 0.008 second-foot Aug. 3, 1936 (gage height, 1.075 feet).

Remarks.- Records excellent except those between 4 and 15 second-feet, which are good, and 

those for periods of ice effect or no gage-height-record, which are fair. This station 

is being operated in connection with a study of the effect of reforestation on stream 

flow. In addition to records of stream flow, records of rainfall, temperature, and 

ground-water levels are beine collected. Weekly records of pround-water elevations 

for 1941 are published in Water-Supply Paper 936.

Extremes.- Maximum discharge during year, 249,000 second-feet Apr. 8 ( gage height, 47.59

 Feet); minimum, 2,390 second-feet Sept. 29 (gage height, 31.60 feet); minimum dally, 

2,580 second-feet Sept. 28, 29.

1931-41: Maximum discharge, 787,000 seconfl-feet Mar. 19, 1936 (gage height, 60.73 

feet), from rating curve extended above 450,000 second-feet; minimum, 618 second-feet 

Sept. 26, 1932 (gage height, 30.89 feet), when York Haven power plant was shut down 

In order to obtain current-meter measurements at low water; minimum dally, 1,380 

second-feet Sept. 26, 1932.

Maximum stage known prior to 1931, 68.3 feet June 2, 1889, from floodmark (discharge, 

about 700,000 second-feet);

Remarks.- Records excellent except those for periods of Ice effect, which are good. Dlscharge below 8,000 second-feet regulated by Metropolitan Edison Co. plant at York Haven. 

Accuracy of the records for the entire period has been verified Independently by the 

Pennsylvania Water & Power Co., by comparison with records obtained at the Safe Harbor, 

Holtwood, and Conowlngo power plants below station.

aquatic vegetation Apr. 27 to June 5, June 9-13, June 21 to Sept. 30; discharge computed on baala of 

discharge measurements, gage heights, and records for stations in the Canisteo and Tloga River Basins.
434 SUSQUEHANNA RIVER BASIN 

Canacadea Creek near Horneil, N. Y.

Location.- Water-stage recorder, lat. 42°20'05", long. 77°41'00", 150 feet upstream from 

norns Bridge, Horneil, Steuben County, and 2 miles upstream from mouth. Prior to 

Oct. 23, 1940, water-stage recorder at site 1.1 miles downstream at different datum.

Drainage area.- 58.7 square miles.

Records available.- October 1940 to September 1941. October 1924 to September 1929 at 

site at seneca Street Bridge, 1.4 miles downstream, and June 1938 to September 1940 at 

sl'te at Erie Railroad bridge, 1.1 miles downstream, both published as Canacadea Creek 

at Horneil, N. Y.

Extremes.- Maximum discharge during year, 3,880 second-feet Apr. 5 (gage height, 5.62 

reet); minimu-n, 3.8 second-feet Sept. 30 ^gage height, 1.125 feet, backwater from 

leaves); minimum gage height, 1.08 feet Sept. 16, 17.

1924-29, 1938-40, 1940-41: Maximum discharge, 4,780 second-feet Mar. 31, 1940 (gage 

height, 8.3 feet, from floodmarks, site and datum then In use); minimum daily, 2.6 

second-feet Sept. 1-3, 1939.

The flood In July 1935 reached a stage of about 12.3 feet, present site, 15.18 feet 

at site and datum in use 1938-40, and 13.30 feet at site and datum In use 1924-29; determined in 1940 from floodmarks (discharge, 21,000 eecond-feet by slope-area method).

Remarks.- Records good except those for periods of ice effect, doubtful or fragmentary 

gage-neight record, or those below 10 second-feet, all of which are fair.

Cooperation.- Results of one discharge measurement furnished by Corps of Engineers, U. S. 

Army.

SUSQUEHANNA RIVER BASIN 439

Cohocton River near Campbell, N. Y.

Location.- Water-stage recorder, lat. 42°15'10", long. 77°13'00", Just downstream from 

highway bridge and 2 miles upstream from Campbell, Steuben County. Datum of gage is 

1,016.58 feet above mean sea level, adjustment of 1912.

Drainage area.- 472 square miles.

Records available.- July 1918 to September 1941.

Average discharge.- 23 years, 431 second-feet.

Extremes^- Maximum discharge during year, 9,940 second-feet Apr. 5 (gage height, 7.66 feet); 

minimum, 16 second-feet Sept. 29 (gage height, 0.385 foot).

1918-41: Maximum discharge, 41,100 second-feet July 8, 1935 (gaga height, 11.6 feet, 

from floodmarks), from combination of velocity-area and slope-area studies and logarithmic plotting; minimum, 8 second-feet Sept. 6, 7, 1934.

Remarks.- Records good except those for periods of ice effect or backwater from weeds, which 

are fair. A diversion from Mud Creek, a tributary above this station, for power development on Keuka Lake probably takes all the ordinary flow from 45 square miles of the drainage area above Lake Lamoka outlet.

Rating tables, water year, 1940-41, except periods of Ice effect or backwater from
