SURFACE WATER SUPPLY OP NORTH ATLANTIC SLOPE BASINS, 1948

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, 1948. 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 11,370 gaging stations 

In the 48 States and also at many in the Territories of Alaska and Hawaii. In July 1948, 

5,960"gaging stations, including those in Hawaii, were being maintained by the Geological 

Survey and cooperating organizations. Miscellaneous discharge measurements were made 

during the water year 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 of the second kind is acknowledged, under the heading "Cooperation," in the introductory matter that precedes the gaging-station records in each volume. In the present 

volume, the section on cooperation of the second kind appears on page 12.

DEFINITION OF TERMS

The units in which stream-flow data are presented in this report and oth'sr terms used 

herein are defined as follows:

"Second-feet" is 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 wat^r 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 runofi' 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 cubic feet. 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 seco.nd-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.

2 SURFACE WATER SUPPLY, 1948 , PART 1

"Contents" Is a term applied to the volume of water In a reservoir. It Is computed on 

the basis of a level pool and does not Include bank storage unless otherwise indicated.

EXPLANATION OP 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 

measurements In determining the dally 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 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 In figure 1.

Rating tables giving the discharge for any stage are prepared from the discharge measurements. The application of the dally mean gage height to those rating tables gives the 

dally wean 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, th& dally 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. At times the stage-discharge relation for a station 

may be temporarily changed by the presence of aquatic growth or debris on the control. 

For such times the daily mean discharge Is computed by what Is essentially the "shiftingcontrol" method-, described above.

At some gaging stations the stage-discharge relation Is affected by backwati^ 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 th* determination of 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 somn stations 

the stage-discharge relation Is affected by changing stage, and for them the rrte 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. For- those 

stations at which the stage-discharge relation is affected by Ice, the days included in 

the periods of Ice effect either are Indicated In the table by symbols referring to a 

footnote that states this fact or are given in a general note following the taMe. The 

days on which discharge measurements were made during or between periods of lc" effect, 

shortly before the first period, or shortly after the last period are similarly Indicated 

by a footnote.

For moat of the gaging stations on streams In the area covered by this report the data 

presented comprise a description of 'the station, a table showing the daily discharge of

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, location, drainage area, records 

available, average discharge, extremes of discharge, general remarks, and notations of revisions of previously published record. The location of the gaging station and the drainage area are obtained from 'the most accurate maps available. Under "Average discharge" is 

given the average discharge for the number of years indicated. It. is not given for stations having less than 10 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 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 nonrecording gage read at the 

time of the crest. Information pertaining to the accuracy of the records and conditions 

which affect the natural flow at the gaging station is given under "Remarks."

For some stations previously published records have been found to be in error on the 

basis of data or information obtained subsequently. 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 station description of all stations for which revised records have been 

published. Listed- therein are all the reports in which revisions appear, 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 years, water years are indicated by . 

only 1 year, for instance, 1933 stands for the water year October 1, 1932, to September 30, 

1933. If there were no daily, monthly, or annual figures of discharge involved in-the 

revision, that fact is brought out by notations after the year dates as follows: (M) means 

that eniy the instantaneous maximum discharge was revised; (m) that only the instantaneous 

minimum Was revised; and (f>) that only peak discharges we're 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 aji stations for which second-feet 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 second-feet per square mill 

and runoff in inches resulting from a revision of the drainage area only are usually not 

published in the annual series of reports.

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

sudden of rapid fluctuation, the table gives the discharge correspon-ling to the dally mean 

gage height, For stations subject tr> such fluctuation the dally mean gage height may not 

indleate 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
ACCURACY OP FIELD DATA AND COMPUTED RESULTS 5

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

or the mean gage height determined from gage-height graphs based on gage readings. For 

periods of rapidly changing stage, the daily mean discharge ia determined from gage-height 

graphs based on gage readings, the frequency of which Is stated in the station description.

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 daily discharge. The column headed 

"Maximum" gives the maximum daily discharge, not the momentary discharge wh«n the water 

surface was at crest stage. Likewise, in the column headed "Minimum" the q-iantlty given 

is the minimum dally discharge. The column headed "Mean" gives the average flow in cubic 

fe«t per second during the month.

Peak discharges with the times of their occurrence are listed below the table of monthly 

discharge for most stations. 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 peak3 a year will be presented. Peak discharges are not published fo- canals, 

ditches, drains, or for any stream for which the peaks are subject to substantial control 

by man.

For most gaging stations on lakes and r-eservoirs 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 Cor 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 or, if the control Is unstable, the frequency oT discharge measurements 

and (8) 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 er.ror in the daily records is believed 

to be less than S percent; "good," less than 10 percent; "fair," less than 15 percent; and 

"poor," probably more than 15 percent. The records of monthly and yearly itean discharge 

and runoff are, in general, more accurate than the daily records.

Yield at some stations as indicated by monthly means may vary widely frcm 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 "seeend-feet per 

square mile" and "runoff in inches" are not published unless storage or diversion records 

are included indicating the extent of the regulati6n or diversion or unless satiafaetory 

adjustments can be made for changes in contents or 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 its inclusion is indicated. Even at those stations 

where adjustments are made, in some Instances large errors in computed yields may occur 

when relatively large negative adjustments are applied or when evaporation is large in 

comparison with the observed discharge. Figures of second-feet per square mile and runoff 

In inches are also omitted if the drainage area Includes large nencontrlbutlng areas or if 

the average annual rainfall over the drainage area is less than 30 inches,
6 SURFACE WATER SUPPLY, 1948, PART 1

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 f.'ow past the 

station. The table of daily discharge affords opportunity for more detailed stidles 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 sich data are 

subject to revision In succeeding water-supply papers.

The records at most of the Rations discussed in these reports extend over a series of 

years. Miscellaneous measurements at many points other than regular gaginf stations have 

been made each year and are published under "Miscellaneous discharge measurements" at the 

end of each report, the streak and points of measurement listed appearing In the same 

relative order as the streams ^nd gaging stations in the body of the report - An index of 

the records obtained prior to i904 has been published in Water-Supply Paper 119.

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

Papers 871 to 884 (see table or^ p. 8), contains, for the area covered by tt«.t report, a 

summary of yearly discharge at gaging stations at which 10 or more complete years of record 

have been collected. These summaries are available also as separate reprirts

Reports 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 have been revised), as well as some records not contained in the annual 

series of water-supply papers. The following table gives the numbers and titles of these

KENNEBEC RIVER BASIN 41

Moosehead Lake at East Outlet, Maine

Location.- Staff gage, lat-. 45°35'10", long. 69°42'45", at wharf at east outlet of lake, 

at Koosehead, Piscataquis County. Datum of gage is 1,011.48 feet above mean sea level 

datum of 1929.

Drainage area.- 1,240 square miles.

Records available.- April 1895 to September 1948.

Extremes.- Maximum gage height observed during year, 17.5 feet June 16; minimum gageheight, 10.0 feet Mar. 17.

1895-1948: Maximum gage height, 18.0 feet May 30, 1902; minimum, 10.0 feet or lower 

present datum, Mar. 20-29, 1911,

Remarks.- Lake is controlled by dams at East and West Outlets originally built prior to 

I84DT East Outlet Dam partly rebuilt of concrete in 1947-48 with gate sills at elevation 7.0 feet. Lake outlet dredged in 1948 to permit drawing level down to elevation 

10.0 feet at a faster rate than formerly. Capacity, 23,735,000,000 cubic feet between gage heights 10.0 and 17.5 feet. Water is used primarily for power, although 

some logs are driven each year. During August and September some water was diverted 

through gates in dam at West Outlet. Gage read at 7 a.m. three times each week.

Cooperation.- Gage-height record furnished by Hollingsworth & Whitney Co.

Revisions.- The column heading for change in contents during month for the 194f and 1947 

water years in Water-Supply Papers 1051 and 1081 erroneously indicated the unit as 

equivalent, second-feet." The figures shown were "millions of cubic feet."

Kecords available.- September 1929 to September 1948. 

Average discharge.- 19 years, 384 second-feet (adjusted). 

Extremes.- Maximum discharge during year, 7,710 second-feet Mar. 22 (gage height, 8.34

reetj; minimum, 19 second-feet Sept. 25 (gage height, 0.57 foot); minimum dally, 24

second-feet Sept. 25.

1929-48: Maxinum discharge, 37,100 second-feet Sept. 21, 1938 (gage h3ight, 17.95

feet, from floodmark), from rating curve extended above 5,700 second-feet on basis of

velocity-area study and roughly checked by comparison with records for other stations

on Parmington River; minimum, 17 second-feet Sept. 28, 1929, Aug. 1, 1936; minimum,

daily, 23 second-feet Aug. 1, 1936; minimum gage height, 0.56 foot Sept. 28, 1941. 

Remarks.- Records excellent except those for periods of ice effect or no gag3-height

record, which are poor. Plow regulated by Otis Reservoir (see p. 157) ani at low

flow by plants above station.

Winter discharge measurement made on this day. 

a Mo gage-height record; discharge computed on basis of weather records and records for East 

Branch Eightmile River near North Lyme.

Note.- Stage-discharge relation affected by ice Dec. 21-25, Jan. 8 to Feb. 21, Feb. 23, 24, Mar. 5,

949149 O - 51 - 16
228 MENUNKETESUCK RIVER BASIN

Menunketesuck River near Clinton, Conn.

Location.- Water-stage recorder, lat. 41°18'10", long. 72°31'00", at Fairy Dell, 100 feet

 downstream from Cobbs Bridge, 1.7 miles north of Clinton, Middlesex Courty, 2.4 miles 

downstream from Kelseytown Reservoir, and 4.9 miles upstream from mouth.

Drainage area.- 11.6 square miles.

.Hecoras available.- June 1941 to September 1948.

Extremes (unadjusted for storage'or diversion).- Miximum discharge during year, 870 second1'eet Nov. 12 (gage height, 6.72 reet), 1'rom rating curve extended above 270 second-feet 

on basis of logarithmic plotting; minimum, 0.16 second-foot Sept. 29, 30 (gage height, 

0.69 foot).

1941-48: Maximum discharge, that of Nov. 12, 1947; no flow at times during August 

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

Remarks.- Records excellent except those for periods of ice effect or bacto-ater from rocks 

ana debris, and those below 2.5 second-feet, which are good, and those for periods of 

no gage-height record, which are poor. The daily-discharge record for all periods 

except those of low flow is a summation of daily flow at gaging station and daily diversion from Kelseytown'Reservoir as measured by venturi meter. During periods of low 

flow, diversions from Kelseytown Reservoir are compensated for by release of water from 

Killingworth Reservoir which is located about 2.5 miles upstream from Kelseytown Reservoir on a small tributary of Menunketesuck River. The drainage area of Killingworth 

Reservoir is so small that its yield is considered negligible during periods of low 

flow when it becomes necessary to draw upon it. Therefore the daily-discharge record 

for periods of low flow Oct. 1-30, July 28 to Aug. 13, Aug. 17 to Sept. 30 is a summation of daily flow at gaging station and daily diversion from Kelseytown Reservoir, 

minus daily draft on Killingworth Reservoir adjusted for daily change in contents in 

Kelseytown Reservoir. Draft on Killingworth Reservoir is determined at a staff-gage 

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

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

reservoir surfaces. Plow at recording gage station regulated by Killingworth and 

Kelseytown Reservoirs and by diversion for domestic water supply from Kelseytown Reservoir.

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

water Co.

Housatonlc River at Stevenson, Conn.

Location.- Water-stage recorder, lat. 41°23'05", long. 73°09'55", in New Haven County, 

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

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

gage is 24.98 feet above mean sea level, datum of 1929 (levels by Corps of Engineers).

Drainage area.- 1,545 square miles.

Kecords available.- August 1928 to September 1948.

Average discharge.- 20 years, 2,504 second-feet (adjusted since 1936).

Extremes.- Maximum discharge during year,. 26,000 second-feet Mar. 23 (gage height, 14.65 

rest); minimum, 40 second-feet Sept. 17 (gage height, 0.44 foot); minimum dally, 63 

second-feet Sept. 26.

1928-48: 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 tiires, 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 Rocky River, Stevenson, and Shepaug Reservoirs having a combined usable 

capacity of 6,600,000,000 cubic feet (see p. S35), and by small diversion from basin 

at Shepaug Reservoir.

Revisions (water years).- W 711: 1929(M). W 781: Drainage area.

a No gage-height record; discharge computed on basis of flocdmarks, engineers' notes and records 

for Tenmile River near Gaylordsville.

Note.- Stage-discharge relation affected by ice Dec. 20-26, Dec. 3O to Mar. 7, Mar. 12-14 (no 

gage-height record Feb. 21-25). Shifting-control method used July 20 to Aug. 29.
238 HOUSATONIC RIVER BASIN

Shepaug River at Woodville, Conn.

Location.- Nonrecording gages at dam at outlet of Shepaug Reservoir, lat. 41°43'16", long. 

V3°17'40 , 1 mile north of Woodville, Litchfield County, and 3 miles upstream from 

Bantam River.

Drainage area.- 38.0 square miles.

Hecoras available.- October 1935 to September 1948.

average aiscnargeT- 13 years, 82.0 second-feet (adjusted).

Extremes.- Maximum discharge observed during year, 1,280 second-feet Mar. 22; no flow

 Nov. 2-12, 19-23.

1935-48: Maximum discharge observed, 6,000 second-feet Sept. 21, 1928; no flow 

at times.

Remarks.- Records good except those for periods of rapidly changing stage cr of ice 

effect, which are fair. 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 second-feet by means of same weir,and 

for discharges above 18.5 second-feet by. a formula selected to fit spillway-crest 

sections. At times of ice effect on spillway, flow computed from gage readings at a 

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

Gages at dam or artificial control usually read once daily. Water diverted from 

Shepaug Reservoir for municipal supply of Waterbury. Flow regulated sirce September 

1933 by Shepaug Reservoir (see p. 235).

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

Meeoras available.- October 1930 to September 1948.

Average discharge?- 18 years, 235 second-feet {adjusted after Oct. 1. 1935).

Extremes.- maximum discharge during year, 3,100 second-feet Mar. 22 (gage height, 7.00 

reet); minimum discharge, 6.0 second-feet Sept. 30 {gage height, 1.44 feet).

1930-48: Maximum discharge, 10,500 second-feet Sept. 21, 1938 {gage height, 12.8 

feet, from floodmarks), from rating curve extended above 3,500 second-feet by logarithmic plotting on basis of two computations of flow over dam: minimum, that of 

Sept. 30, 1948.

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

wnicn are fair. Water diverted from Shepaug Reservoir for municipal supply of Waterbury. Plow regulated'by Shepaug Reservoir (see p. 235), Diurnal fluctuations from an

Nassau County. Datum of gage is 6.55 feet above mean sea level, adjustment of 1912.

Drainage area.- About 10 square miles.

Records available.- January 1937 to September 1948.

Average discharge.- 11 years, 9.58 second-feet.

Extremes.- Maximum discharge during year, 51.9 second-feet Oct. 31 (gage height, 0.949 

root); minimum, 6.05 second-feet Oct. 23 (gage height, 0.237 foot).

1937-48:. Maximum discharge, 104 second-feet Sept. 15, 1944, from rating curve extended above 25 second-feet on basis of logarithmic plotting; maximum gag? height, 4.85 

feet Sept. 21, 1938 (hurricane wave); minimum discharge, 0.09 second-foot Dec. 11, 1941

sea level, da-turn of 1929.

Drainage area.- 34.5 square miles.

Keeords available.- October 1943 to September 1948.

Extremes.- Maximum discharge during year, 80.9 second-feet Apr. 1 (gage height, 0.941 

footy; minimum, 19.2 second-feet Oct. 6 (gage height, 0.46° foot); minimum daily, 20.0 

second-feet Oct. 6.

1943-48: Maximum discharge, 147 second-feet Sept. 14, 1944 (gage height, 1.32 feet, 

0.02 foot backwater from obstruction in channel), from rating curve extended above 70 

second-feet on basis of logarithmic plotting; minimum, that of Oct. 6, 1947; minimum 

daily, that of Oct. 6, 1947.

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

or doubtful gage-height record, which are good. Flow partly regulated by cleaning of 

fish screens and trash racks at outlets of Blydenburgh Pond on main stream and oonds on 

tributaries entering stream above station. This station is 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 collected, some of which are published in 

water-s ipply papers.

Records available.- October 1943 to September 1948.

Extremes.- Maximum daily discharge during year, 77.4 second-feet Nov. 12; minimum daily, 

25.5 second-feet Oct. 15.

1943-48: Maximum daily discharge, 117 second-feet Aug. 7, 1946; minimum daily, 

23.4 second-feet Sept. 10, 1944.

Remarks.- Records good except those for periods of backwater from high tide at gage 1, 

or or doubtful or no gage-height record at gage 2, which are fair. Flow at gage 2 

regulated occasionally by cleaning operations at outlets of ponds atove station. 

Discharge figures given are those of combined flows in main and overflow channels. 

This station is 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 collected, some of which are published in water-supply papers.

264 STREAMS ON LONG ISLAND

Wantagh Stream at Wantagh, N. Y.

Location.- Water-stage recorder and concrete control, lat. 40°40'50", long. 73°30'45", on 

Wantagh Parkway at northwest boundary of village of Wantagh, Nassau County. Datum of 

gage is 16.88 feet above mean sea level, adjustment of 1912.

Drainage area.- About 17 square miles.

uecoras available.- June to October 1883 and July to October 1903 (fragmentary, in Pro 

ressional faper 44), September 1937 to September 1948.

Average discharge.- 11 years (1937-48), 8.27 second-feet.

iixtremes.- Maximum discharge during year, 83.6 second-feet July 13 (gage height, 1.349

 feet); minimum, 1.49 second-feet Oct. 28 (gage height, 0.276 foot); minimum daily, 2.45 

second-feet Oct. 2.

1903, 1937-48: Maximum discharge, 222 second-feet Jan. 6, 1944 (gage height, 2.14 

feet); minimum,1.^6 second-feet Dec. 11, 1941 (gage height, 0.261 foot); minimum daily, 

1.84 second-feet Sept. 12, 1943.

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

shirting control, or backwater from debris, which are good. Flow regulated to some 

extent by Browning Pond, half a mile above station. This station is 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 a^e collected, some of which are 

published in water sapjly papers.

272 HUDSON RIVER BASIN

Hudson River at Green Island, N. Y.

Location.- Water-stage recorder, lat. 42°45'10", long. 73°41'20", at Green Island, Albany

 County, just upstream from Troy Lock and Dam and half a mile downstream from 5th branch 

Mohawk River. Datum of gage is 0.31 foot below mean sea level, datum of 1929 (Corps of 

Engineers bench mark). Auxiliary gage on bypass channel (6th branch Mohawk River) at 

Arch Street Bridge at datum 10.59 feet higher.

Drainage area.- 8,090 square miles (including that; above site of auxiliary gage). 

Records available.- February 1946 to September 1948.

Extremes (main cnannel).- Maximum daily discharge during year, 104,000 second-feet Mar.

 a3; maximum gage height, 22.97 feet Mar. 23; minimum daily discharge, 1,460 secondfeet Sept. 12; minimum gage height, 14.10 feet Sept. 7.

1946-48: Maximum daily discharge, thfct of Mar. 23, 1948; maximum gag3 height, that 

of Mar. 23, 1948; minimum daily discharge, that of Sept. 12, 1948; minimim gage height, 

13.92 feet Sept. 2, 1946.

Flood of Mar. 19, 1936, reached a stage of 29.48 feet at gage on opposite bank, from 

information by Corps of Engineers. Flood of Mar. 28, 1913, prior to construction of 

Sacandage Reservoir and Troy Lock and Dafi, reached a stage about 0.2 foot higher upstream from former dam near same site. Downstream from dams, flood of 1913 was about 

3.3 feet higher than flood of 1936, from information by Corps of Engineers.

Remarks.- Records good. Records of main channel include flow over spillway, through

 wheels, and through lock. Record of flow in bypass channel, which enters Hudson River 

l| miles downstream, are shown separately. Plow appreciably regulated b^ Sacandage 

Reservoir (see p. 279), Indian Lake Reservoir (see p. 275), and Delta, H'nckley, and 

Schoharie Reservoirs (combined capacity, 8,738,000,000 cubic feet). Diurnal fluctuation caused by power plants above station. Diversion above station for water supply 

for New York City (see records for Mohawk River at Cohoes and Schoharie Creek at Burtonsville). During canal navigation season, water is received from Black River Basin 

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.

Cooperation.- Power-plant records furnished by Ford Motor Co. in connection with a Federal 

rower Commission project.

Discharge, in second-feet, of main channel, water year October 1947 to September 1948

294 HUDSON RIVER BASIN

Mohawk River near Little Palls, N. Y.

Location.- Water-stage recorder, lat. 43°00'50", long. 74°46'40", 1,800 fe<;t downstream 

from Hocky Rift Dam, 2 miles upstream from East Canada Creek, and 4| miles southeast 

of city of Little Palls, Herkimer County. Datum of gage is 310.0 feet above mean sea 

level (Barge Canal datum).

Drainage area.- 1,348 square miles.

Kecprds available.- February to April 1901, October 1927 to September 1948. November 1923 

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

Average discharge.- 21 years (1927-48), 2,798 second-feet.

Extremes.- Maximum discharge during year (river channel only), 22,100 second-feet Mar. 20 

[gage height, 16.57 feet); minimum (river channel only), 439 sebond-feet Oct. 27 (gage 

height, 4.30 feeFJ; minimum -daily Tincludlng canal), 695 second-feet Oct. 23.

1927-48: Maximum discharge (river channel only), 25,300 second-feet Oct. 3, 1945 

(gage height, 17.80 feet); minimum .(riVer channel only), probably not less than 305 

second-feet Aug. 8, 1933 (gage height, 4.09 feet); minimum daily (incluiing canal), 

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

Remarks.- Records excellent except those for periods of Ice effect, which are fair. Records of daily discharge include diversion 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 Barge Canal near Rome. Diurnal fluctuation caused by power plants and locks 

and dams on Barge Canal. Plow partly regulated by Delta and Hinckley R3servoirs (combined capacity, 6,120,000,000 cubic feet).

* Winter discharge measurement made on this day.

Note.- Stage-discharge relation affected by ice Dec. 20, 24, 25, Dec. 29 to Jan. 4, Jan. 10 to 

Mar. 1 (doubtful gage-height record Feb. 16, 17, Feb. 20 to Mar. 1).
HUDSON RIVER BASIN 

Mohawk River at Cohoes, N. Y.

295

Location.- Water-stage recorder, lat. 42°47'05", long. 73°42'25", at School Street plant 

or New York Power & Light Corp., 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 Corp.) and October 1925 to September 1948. December 

1917 to July 1925 at Crescent Dam, 2 miles upstream (including diversion through lock 6 

at Crescent Dam).

Average discharge.- 30 years (1918-48), 5,713 second-feet.

Extremes.- Maximum discharge during year, 82,700 second-feet Mar. 20 (gage height, 19.91 

reet}; minimum, 48 second-feet Nov. 5 (gage height, 3.74 feet); minimum daily, 111 

second-feet Oct. 19.

1925-48: 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, 6 second-feet Sept. 28, 1941 .(gage height, 3.40 feet); minimum daily, 23 second-feet 

Aug. 24, 1941.

Remarks.- Records excellent except those for periods of ice effect or shifting control, 

which, are good. Records include small diversion just above gage for Cohoes water supply 

but do 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 Basin 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 flow of Schoharie Creek above Gilboa Dam, a tributary of Mohawk 

River, is diverted out of basin through Shandaken tunnel for New York City water supply. 

Plow partly regulated by storage, principally in Delta, Hinckley, and Schoharie Reservoirs (combined capacity, 8,738,000,000 cubic feet). Extensive diurnal fluctuation 

caused by School Street power plant.

West Canada Creek at Kast Bridge, N. Y.

Location.- Water-stage recorder, lat. 430 04'15", long. 74°59 I 25", 600 feet downstream 

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

County, and 4 miles upstream from mouth and Herkimer. Datum of gage is 438.99 feet 

above mean sea level, datum of 1929.

Drainage area.- 556 square miles.

Kecords available.- May 1905 to December 1909 (1905-6, gage heights and discharge measurements only), January 1912 to December 1913, and October 1920 to September 1948 in 

reports of Geological Survey. January 1910 to December 1911 and January 1914 to September 1920 in reports of State engineer and surveyor.

Average discharge.- 28 years (1920-48), 1,341 second-feet.

Extremes.- Maximum discharge during year, 14,200 second-feet Mar. 28 (gage height, 6.97 

feet); minimum, 152 second-feet Oct. 24 (gage height, 1.55 feet); minimum daily, 394 

second-feet Oct. 12.

1920-48: Maximum discharge, 20,500 second-feet Oct. 2, 1945; maximum gage height, 

10.47 feet probably Feb. 17, 1943, from floodmark in gage well (ice jam); minimum 

discharge, 20 second-feet Sept. 3, 1929 (gage height, 0.90 foot); mininum daily, 59 

second-feet Sept. 2, 1929.

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

engineer and surveyor.

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

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

are fair. Flow partly regulated by Hinckley Reservoir (capacity, 3,320,000,000 cubic 

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

Diversion at Trenton Falls by Ninemile feeder during canal navigation seasun.

Location.- Water-stage recorder, lat. 41°22'20", long. 74°41'50", near highway bridge at 

fort Jervis, Orange County, li miles upstream from Neversink River. Dattm of gage is 

415.35 feet above mean sea level, datum of 1929.

Drainage area.- 3,076 square miles.

Records available.- October 1904 to September 1948.

Average discharge.- 44 years, 5,550 second-feet.

Extremes.- Maximum discharge during year, 96,100 second-feet Mar. 22 (gage Ireight, 14.16

 feet); minimum, 421 second-feet Sept. 27 (gage height, 1.10 feet); minimi-m daily, 540

second-feet Oct. 26.

1904-48: Maximum discharge, 140,000 second-feet May 23, 1942 (gage height, 17.76

feet), from rating curve extended above 89,000 second-feet by logarithmic plotting;

minimum, 175 second-feet Sept. 23, 1908 (gage height, 0.6 foot); minimum daily, 175

second-feet Sept. 23, 1908.

Maximum discharge known, 205,000 second-feet Oct. 10, 1903 (gage heigtt, 23.1 feet,

reported by U. S. Weather Bureau), from rating curve extended above 70,000 second-feet

by logarithmic plotting and velocity-area studies; maximum stage known, ?5.5 feet

Mar. 8, 1904 (ice Jam). 

Remarks.- -Records excellent except those for periods of ice effect or fragmentary or no

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

caused by power plants on tributary streams. Plow regulated by Lake Wallenpaupaek 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 

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

Bridge Reservoirs.

height, 1.02 feet).

1890-1948: Maximum discharge, 232,000 second-feet Mar. 20, 1936 (gage height, 33.07 

feet); minimum, 617 second-feet Sept. 18, 1939 (gage height, 0.69 foot).

Maximum stage known, 33.1 feet Mar. 18, 1865, from floodmarks (discharge, about 

232,000 second-feet).

Remarks.- Records good except those for periods of ice effect, which are fair. Because 

intake to water-stage recorder was usually obstructed by culm, daily discharge was 

determined by using twice-daily readings of auxiliary gage.

Revisions (water years).- W 351: Drainage area. W 781: 1902(M).

Average discharge.- 15 years (1933-48), 6.06 second-feet.

Extremes - Maximum discharge during year, 2Q6 second-feet Mar. 20, 21 (gage height, 3.80 

reet), from rating curve extended above 170 second-feet by logarithmic plotting; minimum, 0.092 second-foot Sept. 16-18 (gage height, 1.27 feet).

1932-48: Maximum discharge, 487 second-feet June 3, 1947, from rating curve extended above 170 second-feet by logarithmic plotting; maximum gage height, 4.45 feet 

June 24, 1940; minimum discharge, 0.065 second-foot Aug. 11, 1934 (gage height, 1.22 

feet).

Remarks.- Records good except those for periods of ice effect or partially obstructed

 intake, which are fair. This station is operated in connection with a study of the 

effect of reforestation on stream flow. In addition to records of stream flow, records 

of precipitation, temperature, barometric pressure, soil temperature, evaporation, and 

ground-water levels are collected. Weekly records of ground-water levels for 1948 

are published in Water-Supply Paper 1126.

Canisteo River below Canacadea Creek, at Hornell, N. Y.

Location.- Water-stage recorder and concrete control, lat. 42°18'50", long. 77°39'05", 

IStTTeet upstream from Erie Railroad bridge in Hornell, Steuben County, 0.25 mile 

upstream from Crosby Creek, and 1.5 miles downstream from Canacadea Creek. Datum 

of gage is 1,131.10 feet above mean sea level (Corps of Engineers bench ma-k).

Drainage area.- 159 square miles.

Kecords avaiiaole.- August 1942 to September 1948.

Extremes.- Maximum discharge during year, 5,300 second-feet Mar. 22 (gage height, 10.19 

reet), from rating curve extended above 2,000 second-feet on basis of computation of 

flow over dam by critical-depth method; minimum dally, 18 second-feet Jan. 31, Feb. 1, 

5, 10, 11; minimum gage height, 2.37 feet July 16.

1942-48: Maximum discharge, 9,340 second-feet May 26, 1943 (gage height, 13.30 

feet), by critical-depth method; minimum, 9.3 second-feet Mar. 4, 1947; minimum gage 

height, 0.76 foot Nov. 18, 20, 1944.

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

record, or shifting control, which are fair. Records Include daily diversion (2 to 4 

second-feet) just above control by Erie Railroad Co. An unknown but relatively small 

amount of water diverted is returned to stream above control. City of Horiell diverts an average of about 3.5 second-feet for municipal supply from Carrirv;ton Creek, 

a tributary above station; sewage enters river below gage. Flood flows afected by 

Arkport Reservoir.

POTOMAC RIVER BASIN 599

North Branch Potomac River near Cumberland, Md.

Location.- Water-stage recorder, lat. 39°37'16", long. 78°46'24", at Wileys Ford Bridge, 

~~ 8 miles south of Cumberland, Allegany County, and'2.1 miles downstream from Wills

Creek. Datum of gage is 585.22 feet above sea level (Corps of Engineers bench mark). 

Drainage area.- 875 square miles. 

Rtcords available.- May 1929 to September 1948. 

Average aiscnarge.- 19-years, l,13o second-feet. '

Extremes.- Maximum discharge during year, 19,600 second-feet Apr. 13 (gage height, 16.00 

 feet); minimum, 92 second-feet Oct. 25, 26 (sage height', 2.75 feet); minimum daily,

92 second-feet Oct. 26. '

1929-48- Maximum discharge, 88,200 second-feet Mar. 17, 1936 (gage height, 29.1

feet), by slope-area method;minimum (river only), 12 second-feet Sept. 22, 1932 (gage

height, 2.38 feet); minimum daily (including flow in canal),-38 second-feet Sept, 24,

1932 * * Maximum stage known prior to 1929, 29.2 feet June 1, 1889 (discharge, about

89,000 second-feet). Flood of Mar. 29, 1924, reached a Stage of 28.4 feet (discharge,

about 82,000 second-feet). 

. Remarks.- Records excellent except those for periods of ice effect or doubtful gage-height

record, which are fair. Some regulation at low flow by reservoir on Stony River, about

79 miles above station (see p. 597), and small amount of inflow from industrial wastes

from water diverted from Evitts Creel*-, mouth of which is below station.

POTOMAC RIVER BASIN 615

Big Spring at Masonville, W. Va.

Location.- Water.-stage recorder, lat. 38°54 I 55", long. 79°04 I 50", on Spring Run, half 

a mile southeast of Masonville, Grant County, and 6 miles southeast of Petersburg.' 

Altitude of gage, 1,580 feet (from topographic map).

Records available.- August 1945 to September 1948.

Extremes.- Maximum discharge during year, 350 second-feet June 29 (gage height, .2.27 

reet), from rating curve extended above 100 second-feet by logarithmic plotting; 

minimum, 4.9 second-feet Oct. 6-8 (gage height, 0.56 foot).

1945-48: Maximum discharge, that of June 29, 1948; minimum, that of Oct. 6-8, 

1947.

Remarks.- Records good except those above 40 second-feet, and those for periods of fragmentary or no gage-height record, which are fair. Big Spring, which emerges at 

several places from 50 to 300 feet above gage, is the source of entire flow except

during wet weather when surface drainage from about half a square mile enters the 

stream above gage. Plow from surface sources is included in the records but is relatively small except during heavy rains.

Discharge, in second-feet, water year October 1947 to Septeaber 19.13
