SURFACE WATER SUPPLY OF NORTH ATLANTIC BASINS, 1947

SCOPE OF WORK

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

stage and flow made on streams, Jakes, and reservoirs In the United States during the 

water year ending September 30, 1947. The work was begun in 1888 in connection w'.th 

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 11,100 gaging stations 

in the 48 States and also at many in the Territories of Alaska and Hawaii. In July 1947, 

5,810 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 p-esent 

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

DEFINITION OP TERMS

The units in which stream-flow data are presented in this report and other terns 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 a<*ea 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 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 second-foe*- 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 g-jge 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, 1947, 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 otherrise indicated.

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 

measurements in determining the daily flow. The records of stage are obtained either from 

direct readings on a nonreeording 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 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. 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 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 obtained 

by means of an auxiliary gage set at some distance froai 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. 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 table. The 

days on which discharge measurements were made during or between periods' of ice effect, 

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

by a footnote.

For most 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

the stream, 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 as 

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

decrease the flow at the gage, artificial regulation from pondage 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 daily discharge if there is extensive regulation (also the minimum discharge if useful); and the 

minimum gage height -(unless it is of no importance). Unless otherwise qualified, the 

maximum discharge corresponds to the crest stage, obtained by use of a water-stage 

recorder or a nonreeording 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 a station at which 

the drainage area of the stream is less than 10 or more than 10,000 square miles or at 

which, on most days, the peak discharge exceeds the mean discharge by less than 10 percent

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 dally mean 

gage height. For stations subject to such fluctuation the daily mean gage height may not 

indicate the true daily mean discharge, which must be obtained by averaging the discharge 

for parts of the day or by using the discharge Integrator, an instrument for obtaining the 

daily mean discharge from a -continuous gage-height graph and containing as an essential 

element a curve representing the stage-discharge relation at the station. For stations 

equipped with nonreeording gages, the table of daily discharge gives the discharge 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 is 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 "Seeond-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 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 some reservoirs a table showing dally 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.
SURFACE WATER SUPPLY, 1947, PART 1 5

ACCURACY OP 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 of discharge measurements 

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 error In the dally 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 yea-ly mean 

discharge and runoff are, In general, more accurate than the dally records.

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 "second-feet 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 satisfactory 

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 ma^ occur 

when relatively large negative adjustments are applied or when evaporation is la"ge 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 noncontrlbiting 

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 a-e situated above most of the diversions from those streams, and therefore the discharge recorded 

does not show the water supply available for further development t as prior aoproTiations 

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 daily discharge affords opportunity for more detailed stulies 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 suih data are 

subject to revision in succeeding water-supply papers.

Papers on surface water supply containing records from 1899 to date, grouped by years 

and drainage basins, are listed by number on page 8. The data for any particular gaging 

station will, in general, be found in the reports covering the years during which the 

station was maintained. For example, the data for 1910 to 1920 for any station in the 

area covered by part 3 are published in Water-Supply Papers 283, 303, 323, 353, 403, 433, 

453, 473, and 503, which contain records for the Ohio River Basin for those year,''.

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 ths year 1939, issued as Water-Supply 

Papers 871 to 884 (see table on p. 8), contains, for the area covered by that 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 reprints.

station at Moosehead.

Note.- Stage-discharge relation affected by Ice Dec. 9 to Mar. 7.
KEHNEBEC RIVER BASIN 43

Kennebec River at Bingham, Maine

Location.- Water-stage recorder, lat. 45°03'05", long. 69°53'15", at Bingham, Somerset 

County, 200 feet downstream from highway bridge, half a mile downstream from Austin 

Stream, l£ miles downstream from Wyman Dam. Datum of gage is 330.2 feet above mean 

sea level, adjustment of 1929.

Drainage area.- 2,710 square miles.

Records available.- June 1907 to June 1910, October 1930 to September 1947.

Average discharge.- 19 years (1907-9, 1930-47), 4,261 second-feet.

Extremes (regulated).- Maximum discharge during year, 44,400 second-feet May 9 (gage 

neignt, u.aa reet); minimum daily, 1,240 second-feet Oct. 6.

1907-10, 1930-47; Maximum discharge, 55,200 secoud-feet Mar. 20, 1936 (gag's height, 

14.44 feet), from rating curve extended above 16,00p second-feet on basis of determination of peak flow at Wyman Dam plus inflow; minimum daily, 485 second-feet Sept. 3, 

1945.

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

record, which are good. Flow regulated by Moosehead, Brassua, Moxle, and Spencer 

Lakes, First Roach, Second Roach, Dead River, and Wyman Ponds (see p. 44). Considerable diurnal fluctuation caused by power plant above station.

* Winter discharge measurement made on this day.

a No gage-height record; discharge computed on basis of recorded range in stage, weather records, 

and records for stations at Westville , Mass., and Putnam, Conn, 

b Stage-discharge relation affected by ice. 

Note.- Backwater from aquatic vegetation Oct. 1 to Jan. 19, May 18 to Sept. 30.
140 THAMES RIVER BASIN

Quinebaug River at Putnam, Conn.

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

boo reet downstream from Muddy Brook (Httle River) and 3 miles dowrstream from French 

River. Datum of gage is 216.76 feet above mean sea level, datum of 1929.

Drainage area.- 331 square miles.

Hecords available.- December 1929 to September 1947.

Average discharge.- 18 years, 544 second-feet.

axtremes.- Maximum discharge during year, 2,200 second-feet Mar. 15 (gage height, 6.49 

feet); minimum, 29 second-feet (regulated) Nov. 30, Aug. 16 (gage height, 1.69 feet); 

minimum daily, 75 second-feet (regulated) Aug. 24.

1929-47: 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 good except those for periods of no gage-height record, which are fair, 

city of Putnam diverts an average of less than 1 million gallons per day from Muddy Brook 

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 cubic feet.

from Waits River. Datum of gage is 374.90 feet above mean sea level, unadjusted.

Drainage area.- 2,825 square miles.

Records available.- July 1918 ttf September 1947.

Average discharge.- 28 years (1918-21, 1922-47), 5,073 second-feet (adjusted).

Extremes/- Maximum discharge during year 43,700 second-feet June 3, 4; maximum gage height, 

27.96"feet June 4; minimum discharge, 646 sec^'J-feet (regulated) Sept. 14 (gage height, 

0.61 foot); minimum daily, 888 second-feet (regulated) Sept. 21.

1918-47: Maximum discharge, 77,800 second-feet Mar. 19, 20, 1936 (gage height, 38.6 

feet, from floodmarks), from rating curve extended above 50,000 second-feet; minimum, 

198 second-feet (regulated) Sept. 4, 1934 (gage height, 0.03 foot); minimum daily, 222 

second-feet (regulated) Aug. 27, 1934.

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

for periods of changing stage computed by using rate of change of stage as a factor. 

Plow regulated by power plants and by First Connecticut and Second Connecticut Lakes, 

Lake Francis, and Comerford Station Pond (see p. 156) and other reservoirs. These 

reservoirs have a combined usable capacity of about 9$ billion cubic feet.

Note.- Stage-discharge relation affected by ice Dec. 2-5, Dec. 16 to Apr. 4.
150 CONNECTICUT RIVER BASIN

Connecticut River at White River Junction, Vt.

Location.- Water-stage recorder, lat. 43°38'50", long. 72°18'45", at downstream side of 

railroad bridge at White River Junction, Windsor County, Just downstream from White 

River. Datum of gage is 321.52 feet above mean sea level, datum of 1929.

Drainage area.- 4,092 square miles.

Records available.- October 1911 to September 1947.

Average discharge.- 36 years, 7,318 second-feet (adjusted).

Extremes.- Maximum discharge during year, 63,400 second-feet June '3 (gfge height, 22.55 

feet, from graph based on gage readings); minimum daily, 1,190 secord-feet (regulated) 

Sept. 28.

1911-47: Maximum discharge, 136,000 second-feet Nov. 4, 1927 (gsge height, 35.0 

feet, present site), from rating curve extended above 70,000 second-feet by logarithmic 

plotting; minimum daily, 534 second-feet (regulated) Sept. 7, 1942.

Remarks.- Records excellent except those for period of ice effect, which are fair. Flow 

regulated by power plants and by First Connecticut and Second Connecticut Lakes, Lak§ 

Francis, Comerford Station Pond (see p. 156),-and other reservoirs. These reservoirs 

have a combined usable capacity of about 10 billion cubic feet. . Cooperation.- Wire-weight gage readings furnished by U. S. Weather Bureau.

 7yu 4JL'42", at plate-girder footbridge on Riverside Street in Hartford, Hartford

County, 1,300 feet downstream from confluence of North and South Branches, 0.9

mile upstream from inlet of Park River conduit, and 2.3 miles upstream from mouth.

Datum of gage is 27.13 feet above mean sea level, datum of 1929 (levels by Department

of Engineering, city of Hartford). 

j

Drainage area.- 74.0 square miles.

Records available.- October 1936 to September 1947.

Average discharge.- 11 years, 114 second-feet.

Extremes.- Maximum discharge during year, 1,060 second-feet Apr. 6 (gage height, 4.72 

reet); minimum, 18 second-feet Oct. 7, 8; minimum gage height, 2.37 feet Nov. 5; 

minimum daily discharge, 22 second-feet Oct. 7-11.

1936-47: Maximum discharge, 5,650 second-feet Jan. 25, 1938 (gage height, 9.16 

feet); minimum, about 4 second-feet (regulated) Sept. 23, 1937; minimum daily, 11 

second-feet Oct. 6, 1941; minimum gage height, 1.58 feet July 23, Aug. 15, 1943, 

result of temporary diversions upstream.

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 reached Mar. 21, 1936 (backwater from Connecticut River).

Remarks.- Records good. Some regulation by mills above station and by storage and 

diversion at Hartford water-supply reservoirs on small headwater streams.

Records available.- October 1936 to September 1947.

Average discharge.- 11 years, 35.4 second-feet.

Extremes.- Maximum discharge during year, 530 second-feet Apr. 5 (gage height, 4.65 

reet); minimum, 1.4 second-feet Dec. 2 (gage height, 0.99 foot), result ,of low 

temperature; minimum daily, 1.7 second-feet July 6, Aug. 15.

1936-47: Maximum discharge, 1,640 second-feet Jan. 25, 1938 (gage height, 11.6 

feet), from rating curve extended above 800 second-feet by logarithmic plotting; 

minimum, 0.04 second-foot (regulated) Sept. 24, 25, 1943 (gage height, 0.75 foot); 

minimum daily, 0.04 second-foot (regulated) Sept. 24, 1943.

Flood of Mar. 12, 1936, reached a stage of 11.2 feet as determined from floodmarks 

by city engineers of Hartford (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, which are fair. Some 

regulation by mills upstream and by storage and diversion at Hartford water-supply 

reservoirs above station.

extremes (unadjusted for storage or diversion).- Maximum discharge during year, 184 secondreet Apr. ti (gage height, 3.37 feet); minimum, 0.39 second-foot probably Dec. 3, Aug. 19, 

20 (gage height, 0.76 foot).

1941-47: Maximum discharge, 560 second-feet Dec. 30, 1942 (gage height, 6.08 feet); 

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 backwater from leaves 

ana those below 2.5 second-feet, which are good, and those for period of no g-?ge-height 

record, which are poor. The daily discharge record for all periods except those for 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 R?servoir 

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 floT Oct. 6 to 

Nov. 11, July 3-17, 31, Aug. 1-20, 25, 26, Sept. 16-20, 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. Flow 

at recording gage station regulated by Killingworth and Kelseytown Reservoirs and by 

diversion for domestic water supply from Kelseytown Reservoir.

Cooperation.- Venturi-meter records and some other data furnished by Guilford-Chester Water Co. 

Discharge, in second-feet,- water year October 1945 to September 1947

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 mile downstream from 

dam of Connecticut Light & Power Co. at Stevenson, Falrfleld County. Datum o<" gage is 

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

Drainage area.- 1,545 square miles.

Kecoras available.- August 1928 to September 1947.

Average aiscnargeT- 19 years, 2,494 second-feet (adjusted since 1936).

sxtremes.- Maximum discharge during year, 14,700 second-feet Mar. 15 (gage height, 11.50 

reet); minimum, 75 second-feet (regulated) Nov. 5 (gage height, 0.86 foot); minimum 

daily, 86 second-feet (regulated) Nov. 28, Jan. 5.

1928-47: 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. Ordinary flow completely regulated by Stevenson hydroelectric 

plant. Plow regulated by Rocky River, Stevenson, and Shepaug Reservoirs, hav'ng a combined usable capacity of 6,600,000,000 cubic feet (see p. 332), and by small diversion 

from the basin at Shepaug Reservoir.

236 HOUSAFONIC RIVER BASIN

Shepaug River at Woodville, Conn.

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

 73"IV'40", 1 mile north of Woodville, Litchfield County, and 3 miles upstream from 

Bantam River.

Drainage area.- 38.0 square miles.

Records available.- October 1935 to September 1947.

Average discharge.- 12 years, 82.9 second-feet (adjusted).

Extremes.- Maximum discharge observed during year, 698 second-feet Mar. 15; no flow (regu-

 lated) Nov. 8-12, 16-29.

1935-47: Maximum discharge observed, 6,000 second-feet Sept. 21, 1938; no flow at 

times (result of regulation).

Remarks.- Records good except those for periods of rapidly changing stage, 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 arti-ficial'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. Plow regulated since September 1933 by Shepaug Reservoir (see p. 232).

Cooperation.- Records finished by Bureau of Engineering, city of Wate-bury.

Naugatuck River near Naugatuek, Conn.

Location.- Water-stage recorded, lat. 41°28a5", long. 73°03'10", 0.2 nile'upstream from 

Beacon Hill Brook, 1.3 miles downstream from Naugatuck, New Haven County, and 12 miles 

upstream from mouth. Datum of gage is 155.17 feet above mean sea level, datum of 1929 

(levels by Corps of Engineers).

Drainage area.- 246 square miles.

Kecords available.- June 1918 to September 1924, September 1928 to September 1947.

Average discharge?- 25 years (1918-24, 1928-47), 434 second-feet (adjusted for storage 

and diversion since October 1935).

Extremes.- Maximum discharge during year, 6,630 second-feet Mar. 14 (gage height, 6.53 

Feet); minimum, 89 second-feet (regulated) Sept. 14 (gage height, 0.38 foot); minimum 

daily, 93 second-feet Sept. 14.

1918-24. 1928-47: Maximunudischarge, 17,000 second-feet Sept. 21, 1938 (gage height, 

12.40 feet), from rating curve extended above 4,700 second-feet by logarithmic plotting 

and verified by comparison with records for headwater streams; mininum, 24 seoond-feet 

(regulated) Oct. 21, 1935; minimum daily, 40 second-feet Oct. 5, 12, 1930, Sept. 7, 

1936; minimum gage height, 0.14 foot July 17, 1939.

Flood of November 1927 reached a stage of 14 feet (discharge, about 18,300 secondfeet ).

Remarks.- Records good except those for periods of no gage-height record and those above 

5,uuu second-feet, which are fair. Flow regulated by plants above station during low 

stages and by Morris, Wigwam, and Pitch Reservoirs having a combined capacity of 

550,000,000 cubic feet (see p. 232). Flow increased by diversion from Shepaug Reservoir into Naugatuck River basin.

Runoff in 

inches

a Ho gage-height record; discharge computed from reconstructed gage-height graph based on recorded 

range in stage and records for nearby streams.

o Backwater from aquatic vegetation (no gage-height record May 10-12, Sept. 13-15, 23-26).

Hote.- Discharge per square mile and runoff in inches not computed because large portion of flow is 

derived from ground-water supply.
STREAMS ON LONG ISLAND 253

Swan River at East Patchogue, N. Y.

Location.- Water-stage recorder and concrete control, lat. 40 0 46'00", long. 720 59'35", 94 

reet downstream from Montauk highway in East Patchogue, Suffolk County, and 200 feet 

downstream from Swan Lake Outlet and l£ miles upstream from mouth. Datum of gage is 2.84 

feet above mean sea level, datum of 1929.

Drainage area.- 8.80 square miles.

Records available.- October 1946 to September 1947.

Extremes (regulated)-- Maximum discharge during year, 20.4 second-feet Aug. 16; maximum 

gage neignt, i.sbb feet Mar. 3 (backwater from high tide); minimum discharge, 0.1 second-foot Feb. 6 (gage height, 0.050 foot); minimum daily, 6.29 second-feet A-;g. 3.

Remarks.- Records good except those for periods of no gage-height record or backwater from 

aquatic vegetation or debris, which are fair. Flow regulated infrequently at outlet of 

Swan Lake. 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 groundwater levels are collected, some of which are published in water-supply papers.

Rating table, water year 1946-47, except periods of bactorater

from aquatic vegetation, debris, or high tide (gage height,

in feet, and discharge, in second-feet)

256 STREAMS ON LONG ISLAND

Connetquot River near Oakdale, N. Y.

Location.- Water-stage recorders, lat. 40°44'50", long. 73°09'00", one (gage 1) on main 

cnannel, at highway bridge 1 Mle west of Oakdale, Suffolk County, a~id one (gage 2) on 

overflow channel a quarter of a mile northeast of gage 1. Datum of gage 1 is 1.56 feet 

above mean sea level, datum of gage 2 is 5.74 feet above mean sea le-rel, both datum of 

1929.

Drainage area.- 11.4 square miles.

Records available.- October 1943 to September 1947.

Extremes.- Maximum daily discharge during year, 62.8 second-feet Apr. 6; minimum daily, 

ati.4 second-feet July 4.

1943-47: Maximum daily discharge, 117 second-feet Aug. 7, 1946; minimum daily, 23.4 

second-feet (regulated) Sept. 10, 1944.

Remarks.- Records good except those for periods of nonexistent stage-discharge relation, 

no gage-height record, or backwater from high tide at gage 1, or no gage-height record 

at gage 2, which are fair. Flow at gage 2 regulated occasionally by cleaning operations 

at outlets of ponds above 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 watersupply papers.

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

 or debris, or doubtful gage-height record, which are good. Slight intermittent regulation by automatic pumping station at railroad upstream and occasional regulation from 

changing stop logs in fish ponds upstream. This station is operated in connection with 

an inventory of ground-water resources on Long Island. In addition to records of strearr 

flow, records of ground-water levels are collected^ some of which are published in 

water-supply papers.

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

or backwater from debris, which are good, and those for periods of no gage-height 

record, which are fair. Plow regulated by Pine'Pond. This station is operate! 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.

Extremes.- Maximum discharge during year, 23,600 second-feet June 3 (page height, 11.37

 feet); minimum, 616 second-feet (regulated) Jan. 10, Sept. 20 (gage height, 3.04 feet); 

minimum daily, 620 second-feet Jan. 10.

1907-47: Maximum discharge, 27,400 second-feet Mar. 27, 1913; maximum gage height, 

12.10 feet Mar. 19, 1936 (ice jam); minimum discharge, 112 second-feet July 26, 1934 

(gage height, 1.96 feet); mininum daily, 114 second-feet July 26, 1934.

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

 which are good, and those for periods of ice effect or partially olstructed intake, 

which are fair. Flow partly regulated by Indian Lake (see p.273) and other reservoirs 

above station.

HUDSON RIVER BASIN 269

Hudson River at Green Island, N. Y.

Location'.- Water-stage recorder, lat. 42°45'10", long. 73°41'20", at Grejsn 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 brancJr of 

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 1947.

Extremes (regulated).- 1946: Maximum daily discharge during period February to September, 

79,yuu second-feet Mar. 10; maximum gage height, 22.13 feet Mar. 10; minimum dsily discharge, 1,690 second-feet Sept. 2; minimum gage height, 13.92 feet Sept. 2.

1946-47: Maximum daily discharge during water year, 74,200 second-feet June 4; 

maximum gage height, 21.64 feet May 6; minimum daily discharge, 2,240 second-feet 

Sept. 1; minimum gage height, 14.02 feet Dec. 30, Sept. 2.

Flood of Mar. 19, 1936, reached a stage of 29.48 feet, from information by Corps of 

Engineers. Flood of Mar. 28, 1913, prior to construction of Sacandaga Reservoir and 

Troy Lock and Dam, 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

wneeis, and through lock. Records of flow in by-pass channel, which enters the Hudson 

li miles downstream, are shown separately. Flow appreciably regulated by Sacardaga 

Reservoir (see p. 277), Indian Lake Reservoir (see p. 273), and Delta, Hinckley, 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). 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 

power commission project.

Location.- Water-stage recorder, lat. 43°17 I 30", long. 73°39'55", at upstream end of feeder canal at city of Glens Falls, Warren County. Auxiliary water-stage recorder 1,000 

feet downstream from cement mill and 3.3 miles downstream from base gage.

Records available (navigation seasons only).- May 1927 to September 1947 in reports of 

geological Survey.May 1919 to June 19^1 and October 1924 to September 1925 in reports 

of State engineer and surveyor.

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

which are fair. Discharge computed by using fall as determined by aixiliary waterstage recorder as a factor, in conjunction with the shifting-control method. Plow 

regulated in accordance with requirements of Champlain Canal and for floating logs. 

Operation of feeder discontinued Dec. 4 and resumed May 3; available record began 

June 21. During period of no diversion, the feeder may carry a small flow representing leakage through head gates and runoff from area tributary to feeder above station.

281

Location.- Water-stage recorder, lat. 43°18'15", long. 73 0 32'50", at Dunham Basin,

Washington County, 100 feet upstream from Bond Brook and 8 miles downstream from feeder 

dam at. Glens Palls. Datum of gage is 139.88 feet above mean sea level (Barge Canal 

datum).

Records available.- September 1945 to September 1947 (navigation seasons only).

Remarks.- Records excellent except those for periods of no gage-height record or backwater from Bond Brook, which are fair. Plow regulated in accordance with requirements 

of Champlaln Canal. Operation of feeder discontinued Dec. 4 and resumed May 3. Discharge shown during intervening period consists of leakage through head gates and runoff from area tributary to feeder above station. This flow may continue during period 

of no record

290 HUDSON RIVER BASIN

Mohawk River below Delta Dam, near Rome, N. Y.

Location.- Water-stage recorder, lat. 43°15'50", long. 75°26'10", at Spring Bmok fish 

hatchery, 1 mile downstream from Delta Dam and 4 miles north of Roire, Oneida County. 

Datum of gage is 474.00 feet above mean sea level (Barre Canal datum).

Drainage area.- 150 square miles.

Records available.- October 1927 to September 1947 in reports of Geological Survey.

December 1919 to September 1926 (prior to July 1921, gage heights oily) in reports of 

State engineer and surveyor.

Average discharge.- 26 years (1921-47), 405 second-feet (unadjusted).

Extremes.- Maximum discharge during year, 6,350 second-feet May 22 (gage height, 9.86 

reetj; minimum, 128 second-feet (regulated) Oct. 7 (gage height, 1.49 feet); minimum 

daily, 179 second-feet (regulated) Oct. 1.

1927-47: Maximum discharge, 8,560 second-feet Oct. 2, 1945 (gag9 height, 11.18 

feet); minimum, 30 second-feet (regulated) Sept. 27, 1945 (gage'height 0.65 foot); minimum daily, 45 second-feet (regulated, estimated) Jan. 17, 1931.

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

Klver through Forestport feeder and Black River Canal (flowing south) into Delta Reservoir above station. Flow almost completely regulated by Delta Reservoir (capacity, 

2,800,000,000 cubic feet). Small quantity of water diverted from Delta Reservoir for 

fish hatchery use and later returned to river, part above and part below station.

HUDSON RIVER BASIN 291

Mohawk River near Little Falls, H. Y.

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

from Kocky Rift Dam,'2 miles upstream from East Canada Creek, and 4-| miles southeast 

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

level (Barge Canal datum).

Drainage area.- 1,348 square miles.

Records available.- February to April 1901, October 1927 to September 1947. November 1923

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

Average discharge.- 20 years (1927-47), 2,810 second-feet.

Extremes.- Maximum discharge during year (river channel only), 22,900 second-feet June 4

 (gage 'heighis, 16.89 feet); minimum (river channel only), 562 second-feet (regulated) 

July 3 (gage height, 4.57 feet); minimum daily (including canal), 881 second-feet 

(regulated) Sept. 7.

1927-47: 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 (rSgulated) Aug. 8, 1933 (gage height, 4.09 feet); minimum daily (including 

canal), probably not less than 463 second-feet (regulated) Sept. 2, 1934.

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

 record, 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. Flow partly regulated by Delta and 

Hinckley Reservoirs (combined capacity, 6,120,000,000 cubic feet).

* Winter discharge measurement made on this day.

d Doubtful gage-height record; discharge computed on basis of reconstructed gage-height graph, 

weather records, and records for upstream stations.

Note. - Stage-discharge relation affected by Ice Dec. 27 to Jan. 15, Feb. 5-10, 12-22 (do-ibtful 

gage-heIght record Feb. 5-9).

885474 O - 50 - 20
292 HUDSON RIVER BASIN

Mohawk River at Cohoes, N. Y.

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

oi' 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 dan and School Street

 plant oi1 New York Power & Light Corp.) and October 1925 to September 1947. December 

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

at Crescent Dam).

Average discharge.- 29 years (1918-47), 5,723 second-feet.

extremes.- Maximum discharge during year, 51,300 second-feet (regulated) Apr. 7 (gage

 height, 17.26 feet); minimum, 106 second-feet (regulated) Sept. 13 (gage height, 4.46

feet); minimum daily, 261 second-feet (regulated) Oct. 13.

1925-47: 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 (regulated) Sept. 28, 1941 (gage height, 3.40 feet); minimum

daily, 23 second-feet (regulated) Aug. 24, 1941. 

Remarks. - Records excellent except those for periods of ice effect, w'lich are fair. Rec-

 ords 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 Blaik River Basin through 

Black River Canal (flowing south) and Lansing Kill, and possibly f"om 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. Flow partly 

regulated by storage, principally in Delta, Hinckley, and Schoharie Reservoirs (combined 

capacity, 8,738,000,000 cubic feet). Diurnal fluctuation caused bv School Street power 

plant.

TTSbTeet Jan. 20 (ice jam); minimum discharge, 11.5 second-feet Seit. 19 (gage height,

1923-47: Maximum discharge, 11,900 second-feet Sept. 22, 1938 (gage height, 12.1 

feet, from floodmarks), from rating curve extended above 7,200 second-feet on basis of 

logarithmic plotting and by computation of peak flow over two dams and by slope-area 

method; minimum, 1.7 second-feet Oct. 15, 1930.

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

good, and those for periods of ice effect, which are fair. Practically entire low flow 

(about 5 second-feet) or Quacken Kill diverted for municipal supply.

Note.- Stage-discharge relation affected by ice Dec. 2-7, Dec. 16 to Jan. 13, Jan. 23, Feb. 4 to 

Mar. 15, Mar. 19 (fragmentary gage-height record Jan. 3, 4).
378 DELAWARE RIVER BASIN 

Delaware River at Port Jervis, N. Y.

Location.- Water-stage recorder, lat. 41°22'20", long. 74 0 41'50", near highway bridge at

Fort Jervis, Orange County, 1^ miles upstream from Neversink River. Datum of gage is

415.35 feet above mean sea level, dbtum of 1929. 

Drainage area.- 3,076 square miles. 

Kecorcts available.- October 1904 to September 1947. 

Average discharge.- 43 years, 5,553 second-feet. 

Kxtremes.- Maximum discharge during year, 66,500 second-feet Apr. 6 (gage height, 12.24

feet); minimum, 804 second-feet (regulated) Sept. 29 (gage height, 1.60 feet); minimum

daily, 924 second-feet Sept. 28.

1904-47: Maximum discharge, 140,000 second-feet May 23, 1942 (g?ge 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 height, 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, 25.5 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. Flow regulated by Lake Wallenpaupack and

Toronto, Cliff Lake, and Swinging Bridge Reservoirs (combined capacity, 12,300,000,000

SUSQUEHANNA RIVER BASIN 465

Susquehanna River at Wilkes-Barre, Pa.

Location - Water-stage recorder, lat. 41°15'00", long. 75°53'10", at Market Street Bridge 

in Wilkes-Barre, Luzerne County, 1.6 miles upstream from Toby Creek; and auxiliary 

wire-weight gage 2,100 feet upstream on North Street Bridge. Datum of gages is 512.07 

feet above mean sea level, datum of 1929, New York-Pennsylvania supplementary adjustment of 1943.

Drainage area.- 9,960 square miles.

Kecprds available.- March 189? to December 1913, October 1918 to September 1921, and

October 1931 to September 1947 in reports of Geological Survey. March 1899 to September 1947 in reports of Pennsylvania Department of Forests and Waters. Gage-height 

records collected at same site since November 1890 are contained in reports of U. S. 

Weather Bureau.

Average discharge.- 48 years (1899-1947), 13,510 second-feet.

Kxtremes.- Maximum discharge during year 151,000 second-feet Apr. 7 (gage height, 24.60 

feet, from water-stage recorder); minimum, 2,390 second-feet Sept. 30.

1890-1947: 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.

Revised figure of peak discharge for Sept. 21, 1938, is 36.5 second-feet, superseding those published in Water-Supply Papers 867 and 1031.

Remarks.- Records good. 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, and ground-water levels are collected. Weekly records of 

ground-water levels for 1947 are published in Water-Supply Paper

Revisions.- Revised figures of discharge for high-water periods in-the water years 1934-44 

are given herewith. They supersede those published in Water-Supply Papers 761, 773-E,

Hote.- Stage-discharge relation affected by ice Dec. 2-5, Dec. 16 to Jan. 14, Jan. 17, 18, SI-24, 

Feb. 5-9, Feb. 11 to Mar. 14, Mar. 19. Backwater from weeds Aug. 19 to Sept. 30 (no gage-height 

record Sept. 2-7).
488 SUSftUEHANNA RIVER BASIN

Shackham Brook near Truxton, N. Y.

Location.- Water-stage recorder and concrete control with V-notch weir, lat. 42°46'00",

 long. 76°01'10", a quarter of a mile downstream from unnamed tributary, three-quarters 

of a mile upstream from mouth, and 5 miles north of Truxton, Cortland County. Datum of 

gage is 1 281.52 feet above mean sea level, adjustment of 1912 (levels by Corps of 

Engineers).

Drainage area.- 3.12 square miles.

Records available.- November 1932 to September 1947.

Average discharge.- 14 years (1933-47), 6.18 second-feet.

Extremes.- Maximum discharge during year, 487 sceond-feet June 3 (gage height, 4.32 feet),

 from rating curve extended above 170 second-feet by logarithmic plotting; minimum, 0.138 

second-foot Sept. 21 (gage height, 1.32 feet). .

1932-47- Maximum discharge, thqt of June 3, 1947; 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 backwater from gravel,

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

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 1947 are 

published in Water-Supply Paper 10.36.

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

ibu feet upstream from Er'e 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 mark).

Drainage area.- 159 square miles.

Records available.- August 1942 to September 1947.

Extremes.- Maximum discharge during year, 8,210 second-feet June 3 (gage height, 12.45 

reet) -. minimum, 9.3 second-feet (result of local ice conditions) Mar. 4; minimum 

gage height, 2.S9 feet Oct. 11.

1942-47: Maximum discharge, 9,340 second-feet May 26, 1943 (gage height, 13.30 

feet), by critical-depth method; minimum, that of Mar. 4, 1947; minimum gage height, 

0.76 foot Nov. 18, 20, 1944.

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

which are fair. Records include daily diversion (2 second-feet 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 Hornell diverts ar 

average of about 3.5 second-feet for municipal supply from Carrington Creek, a 

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

Arkport Reservoir.

Discharge, in second-feet, water year October 1946 to September 1947

Winter discharge measurement made on this day.

d Doubtful gage-height record; discharge computed from reconstructed gage-height graph based on 

available record and normal shape of peaks.

Note.- Stage-discharge relation affected by ice Dec. 2, 3, 14-16, 18-22, Dec. 25 to Jan. 3, 

Jan. 5-10, 12-14, 22, 23, Feb. 3 to Mar. 14, Mar. 16-21, 26-31. Intake partially obstructed Apr. 5, 

1O, 11, 13-15, May 21, 22, June 3; discharge computed on basis of discharge measurements, reconstructed gage-height graph based on outside-gage readings, high-water mark, or normal shape of peak, 

engineers' notes, and records for other stations in the area. Shifting-control method used Mar. 28 

to Apr. 5, Apr. 30, July 29 to Aug. 6.
SUSQUEHANNA RIVER BASIN 505

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 i:; 

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

Drainage area.- 472 square miles.

Records available^- July 1918 to September 1947.

Average discharge^- 29 years, 450 second-feet.

Extremes.- Maximum discharge during year, 11,700 second-feet June 3 (gage height, 8.10

feet); minimum, 85 second-feet Aug. 9, Sept. 30; minimum gage height, 0.71 foot Oct. 12. 

1918-47: Maximum discharge, 41,100 second-feet July 8, 1935 (gage height, 11.6 feet, 

from floodmarks), from velocity-area determinations and logarithmic plotting; minimum, 

8 second-feet Sept. 6,7, 1934.

Remarks.- Records excellent except those for periods of backwater from weeds and/or leaves, 

wnich are good, or those for periods of ice effect, which are fair. During each year a 

large part of flow from 45 square miles of drainage area above Lake Lamoka Outlet on Mud 

Creek, a tributary above this station, is diverted into Keuka Lake for power development.

Drainage area.- 49.4 square miles.

Kecoras available.- July 1938 to September 1947.

Extremes.- Haxiinum discharge during year, 1,300 second-feet Sept. 6 (gage height, 6.37 

reet); minimum, 2.5 second-feet Oct. 7-9 (gage height, 2.08 feet).

1938-47: Maximum discharge, 2,300 second-feet July 27, 1945 (gage height, 10.02 

feet); minimum, 0.8 second-foot Oct. 3, 7, 1941, Aug. 26, 1943. 

Maximum stage known, about 13.5 feet in August 1933.

Remarks*. - Records excellent except those for periods of ice effect, which are fair. Low 

1'J.ow regulated by storage and diversion at Burnt Mills Dam, by filtration plant 7 miles 

above station, and by inflow pumped from Patuxent River Basin as required for water 

supply for Washington Suburban Sanitary District.

Cooperation.- Records of diversions and change in reservoir contents furnished by Washington Suburban Sanitary Commission. Slight inflow above station due to-sewage for several 

communities not included in table with diversion and inflow.

Location.- Water-stage recorder, lat. 38°19', long. 77°31',- lj miles upstream from dam of

 Virginia Electric & Power Co., 2^ miles downstream from Motts Run, and 3j miles upstream from Fredericksburg, Spotsylvania County. Datum of gage is 56.18 feet above 

mean sea level, datum of 1929. Culpeper supplementary adjustment of 1943.

Drainage area.- 1,599 square miles.

Records available.- September 1907 to September 194V.

Average discharge.- 40 years, 1,648 second-feet.

Extremes.- Maximum discharge during year, 11,600 second-feet Mar. 15 (gage height, 5.96

 feet); minimum, 278 second-feet Aug. 17 (gage height, 0.72 foot).

1907-47: Maximum discharge, 140,000 second-feet Oct. 16, 1942 (gage height, 25.9 

feet, from floodmarks), from rating curve extended above 70,000 second-feet o~i basis 

of determinations of flow over dam and slope-area determinations at gage heights 25.1 

and 25.9 feet; minimum, 5 second-feet Oct. 11, 12, 1930 (gage height, -0.2? foot). 

Flood of June 1889 was probably several feet lower than flood of October 1942.
