SURFACE WATER SUPPLY OF NORTH ATLANTIC SLOPE BASINS, 1940

- SCOPE OF WORK

This volume Is one of a series of 14 reports presenting results of measu-ements of stage 

and flow made on streams, lakes, and reservoirs In the United States during the water year 

ending September 30, 1940. The work was begun In 1888 In connection with special studies 

relating to Irrigation. Measurements of the flow of streams and of the sta^e and" contents 

of lakes and reservoirs have been made at about 8,800 gaging stations In thr» United States 

and also a* many gaging stations In Alaska and Hawaii. In July 1940, 4,760 gaging stations 

were being maintained by the Geological Survey and cooperating organizations. Miscellaneous discharge measurements were made at many other points.

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

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

kind Is acknowledged In connection with the description of each station aff ^ted; cooperation of the second kind Is acknowledged on page 10.

DEFINITION OF TERMS

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

herein are defined as follows:

11 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 watn- flowing per 

second from each square mile of area drained, on the assumption that the rui-off Is distributed uniformly both as regards time and area.

"Run-off 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 run-off 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 eecond-foot for 24 

hours. It Is equivalent to 86,400 cubic feet, 1.983471 acre-feet, or 646,31 7 gallons and 

represents a run-off of 0.0372 Inch from one square mile.

"Stage-discharge relation" is an abbreviation for the term "relation of gage height to 

discharge."

"Control" Is a term used to designate a feature below the gage that defines the stagedischarge relation at the gage. "This feature may be a natural section, a nach of the 

channel, or an artificial structure.

EXPLANATION OF DATA

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

discharge, and general Information used to supplement the records of stage and discharge
2 EXPLANATION OF DMA

measurements In determining the dally flow. The records of stage are obtalnM either from 

direct readings on a nonrecordlng gage or from a water-stage recorder that g'.ves a continuous record of the fluctuations. Measurements of discharge are made with a current 

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

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

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

mean dally discharge, from which the monthly and yearly mean discharge ar-e computed.

For most of the gaging stations In the area covered by this report the data presented 

comprise a description of the station, a table showing the dally discharge of the stream, 

and a table of monthly and yearly discharge and run-off. Skeleton rating tables are published except for those stations whose dally discharge for the greater part cf the year 

was determined by the shifting-control method, the slope method, or other special methods.

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

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

decrease the flow at-the gage, artificial regulation from 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 rnd gage 

height; the minimum discharge If there Is little or no regulation; the.mlnlmm dally 

discharge If there Is extensive regulation (also the minimum discharge If useful); and the 

minimum gage height (unless It Is of no Importance). Unless otherwise qualified, the 

maximum discharge corresponds to the crest stage, obtained by use of a water-stage recorder or a nonrecordlng gage read at the time of the crest. Likewise the minimum discharge represents the lowest stage, unless otherwise qualified. The peak discharge for 

the year with the time of Its occurrence Is given below the table of monthly discharge for 

some stations. Selected lower peaks are also given If the peak discharge exceeded the 

mean discharge for that day by more than 10 percent. This supplementary Information isgenerally not given for stations having drainage areas of less than 10 square miles or 

more than 10,000 square miles.

The table of dally .discharge gives, for stations equipped with nonrecordlrc gages, the 

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

twice-daily readings. For flashy floods the mean dally discharge Is determined from gageheight graphs based on gage readings made once or twice dally or oftener, as stated In the 

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

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

dally gage height may not Indicate the .true mean dally discharge, which must be obtained 

by averaging the discharge for Intervals of the day or by using the discharge Integrator, 

'an Instrument for obtaining the1 mean dally discharge from a continuous gage-freight graph 

and containing as an essential element the rating curve of the station.

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

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

or fall In a reach of the stream as a factor In the determination of discharge Information requisite for determining the slope or fall Is obtained by means of an auxiliary

EXPLANATION OF DATA 3

gage set at some distance from the base gage. The auxiliary gage, if one Is used, Is 

described under "Location." 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 occasional winter discharge 

measurements and gage heights, consideration being given to the available information on 

temperature and precipitation, notes by gage observers and engineers, and comparable 

records of discharge for stations In the same or nearby basins. The days Included In the 

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

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

for each month of the figures for that month given in the table of daily discharge. The 

column headed "Maximum* gives the maximum dally discharge and not the Instantaneous discharge when the water surface was at crest stage. Likewise, In the colunm headed "Minimum" 

the quantity given Is the minimum dally discharge. The column headed "Me-m" gives the 

average flow In cubic feet per second during the month.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

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

Interpretation of records.

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

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

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

a higher percent.

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

owing to diversion, consumption, regulation by storage, Increase or decrease in evaporation 

due to artificial causes, or other factors. For such stations figures of "second-feet per 

square mile" and "run-off in inches" are not published unless storage or diversion records 

are Included indicating the extent of the regulation or diversion or unle^e satisfactory 

adjustments can be made for changes in contents of reservoirs or for othe- changes Incident to use and control. Figures of second-feet per square mile and nr?-off In Inches 

are also omitted If the drainage area Includes large noncontrlbuting area" 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 9 vates 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 prlo" appropriations 

below the station must first be satisfied.

The table of monthly discharge gives a general Idea of the flow at the station. The 

table of dally discharge allows more detailed studies of the variation in flow. It should 

be borne In mind, however, that the observations In each succeeding year may be expected

to throw new light on data previously published, and that greater degrees of refinement 

in computations, and records nay be warranted with the Increase In data and tire use of 

Improved equipment. s

and weather records.
PENOBSCOT RIVER BASIN 27

Penobscot River at Passadumkeag, Maine

Location.- Water-stage recorder, let. 45°10'55", long. 68°37'20*, In Passadumkeag, 

penobscot County, at head of Passadumkeag Rips, and 1,200,feet downstream from 

Passadumkeag River. Datum of gage Is 123.6 feet above mean sea level (unadjusted).

Drainage area.- 7,000 square miles (Including about 240 square miles drained by 

unamcieriain Lake through Telos Canal).

Records available.- November 1938 to September 1940.

Extremes.- Maximum discharge, during year, 106,000 second-feet Apr. 14 (g"«e height, 

13.62 feet); minimum, 2,840 second-feet Har. 5.

1938-40: Maximum discharge, that of Apr. 14, 1940; minimum, that of Mar. 5, 1940.

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

effect, or backwater due to aquatic vegetation, all of which are good. Flow regulated 

by North Twin and Rlpogenus Lakes, (see p. 24 ), on West Branch of Penobscot River 

(combined capacity, 45,000,000,000 cubic feet), and many smaller reservoirs.

Cooperation.- Results of many winter discharge measurements furnished by T. W. Clark, 

nyaraullc engineer, of Old Town.

and those below 1,000 second-feet, which are good. Boston Metropolitan District and 

city of Worcester divert water from basins of Sudbury and South Branch of Nashua Rivers 

and from Lake Cochitua1;e; discharge at gaging station Includes water wasted from these 

diversions. Flow partly regulated by power plants and Winnlpesaukee, Squain, Newfound, 

and other lakes.

THAMES RIVER BASIN 11 

Quinebaug River at Jewett City, Conn.

Location.- Water-stage recorder, lat. 41 835'55", long. 71°59'05", at Jev«tt City, New 

London County, 570 feet downstream from outlet of canal from Slater rtlls at mouth 

of Pachaug River and 1,000 feet downstream from railroad bridge. Datum of gage is 

63.07 feet above mean sea level (general adjustment of 1929).

Drainage area.- 711 square miles.

Records available.- July 1918 to September 1940.

Average discharge.- 22 years, 1,265 second-feet.

Extremes.- Maximum discharge during year, 9,400 second-feet Apr. 14 (gag* height, 14,42 

feet); minimum, about 20 second-feet at times when mills upstream were shut down: 

minimum daily, about 20 second-feet Oct. 15, 21, 22, 29, Aug. 18, 25, Sept. 1, 22.

1918-40: Maximum discharge, 29,200 second-feet Mar. 19, 1936 (gag-* height, £4.0 

feet, from floodmarks), by computations of flow over three nearby darrs; minimum, about 

20 second-feet at times when mills upstream were shut down; minimum daily, about 20 

second-feet on several days during July to September 1939, August and September, 1940.

Remarks.- Records excellent except those for periods of ice effect, or cf doubtful or no 

gage-height record, which are poor. Flow regulated by many ponds and reservoirs, the 

largest of which are Pachaug Pond and Lake Chaubunagungamaug.

Location.- Lat. 42°36'40", long. 72°33'20'1 , at dam of Turners Falls Power & Electric Co., 

Turners Falls, Franklin County, just upstream from Falls River.

Drainage area.- 7,163 square miles (revised). 

Records available.- January 1915 to September 1940.

Average discharge.- 25 years, 11,890 second-feet (adjusted for change In reservoir 

contents).

Remarks.- Discharge computed by adding flow over and through dam, flow fcr factories 

tnrough canal that diverts around dam, and flow through power station? 1 and 2 of 

Turners Falls Power & Electric Co. Flow regulated by storage In First Connecticut 

and Second Connecticut Lakes (see p. 130), Comerford Station Pond, Late Sunapee, four 

reservoirs In Mascoma River Basin, and several other reservoirs, all cf which have a 

combined usable capacity of about 9 billion cubic feet, and since Mar. 23, 1940, by 

Lake Francis (see p. 130) which has a usable capacity of 4,325,900,000 cubic feet.

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

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

above mean sea level (general adjustment of 1929).

Drainage area-- 25.3 square miles.

Records available.- October 1936 to September 1940.

Extremes.- Maximum discharge during year, 1,030 second-feet May 31 (gae« height, 8.17

reet;; maximum gage height, 10.26 feet Jan. 15 (backwater from ice); minimum discharge,

1.1 second-feet Sept. 23 (gage height, 0.93 foot); minimum dally, 1.5 second-feet Sept.

 Revisions.- Figures of minimum and minimum daily discharge for the water year 

1938-39 have been revised as follows, superseding those published in Water-supply Paper 

871: Minimum discharge, 1.1 second-feet Sept. 19, 20 (gage height, 0.93 foot); minimum daily, 1.2 second-feet Sept. 19, 20, 23, 24.

1936-40: Maximum discharge, 1,640 second-feet Jan. 25, 1938 (gar> height, 11.6 

feet), from rating curve extended above 800 second-feet by logarithmic plotting; minimum, 0.7 seoond-foot Sept. 25, 1937 (gage height, 0.82 foot), result of temporary regu- lation; minimum daily, 0.9 second-foot Sept. 24, 193?.

Flood of Har. 12, 1936, reached a stage of 11.2 feet as determined by city engineers 

of Hartford, from floodmarks (discharge, probably 1,520 second-feet, from current 

rating curve after adjusting observed gage height to equivalent gage height for present conditions).

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

trash on control, which are fair. Infrequent low-water regulation by small mills 

above station.

Revisions.- Revised figures of discharge for the water year 1938-39, superseding those 

published in Water-supply Paper 871, are given herein.

Rating tables, Oct. 1, 19SS to Sept. 30, 1940, except periods of lee effect aM backwater fro» 

trash on control (gage height, In feet, and discharge, In second-feet)

Note.- Ho gage-height record Oct. 11-30, July 12-30j discharge computed on basis of high-water 

mark Jan. 16, recorded range of stage July 12-30, weather records and records for Tenmlle Hirer 

near Oaylordsvllle, Pomperaug Hirer at Southbury, and Saugatuck Hirer near Wrstport. StagedlBCharge relation affected 6y Ice Dec. 15, 24-30, Jan. 1 to Feb. 11, Feb. U to Mar. 2, Mar.

198 HOUSATONIC RIVER BASIN

Shepaug River at Woodvllle, Conn.

Location.- Qages at dam at outlet of Shepaug Reservoir, lat. 41 043'16", lor«r. 73°17*40", 

l mile north of Woodvllle, Lltchfleld County, and 3 miles upstream-from Bantam River.

Drainage area.- 38.0 square miles.

Records available.- October 1935 to September 1940.

Extremes.- Maximum discharge during year, 1,950 second-feet Apr. 8, from graph based on 

dally gage readings; minimum observed, 2.4 second-feet (regulated) on mrny days.

1935-40: Maximum discharge observed, 6,000 second-feet Sept. 21, 195*^; no flow 

at times (result of regulation).

Remarks.- Records good except those for periods of Ice effect or rapidly changing stage, 

milen 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 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 the 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 the slnrp-crested 

weir prior to Its removal. Gages at dam or artificial control read onct* dally during 

ordinary flow and more frequently during periods of extremely high flow. Water 

diverted from Shepaug Reservoir for municipal supply of Waterbury. Flov regulated 

by Shepaug Reservoir (capacity, 96,000,000 cubic feet).

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

202 HOU8ATONIC RIVER BASIN

Naugatuck River near Naugatuck, Conni

Location.- Water-stage recorder, lat. 41°28'15", long. 73°03'10", 0.2 mile upstream from

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

upstream from mouth. Datum of gage Is 155.17 feet above mean sea level (genrral 

adjustment of 1929).

Drainage area.- 246 square miles.

Records available.- June 1918 to September 1924', September 1928 to September 19AO.

Average discharge.- 18 years, 435 second-feet (unadjusted prior to 1936).

Extremes.- Maximum dlschargs during year, 7,100 second-feet Apr. 9 (gage height, 7.54 feet);

 minimum, 67 second-feet Aug. 12 (gage height, 0.30 foot); minimum dally, 80 second-feet 

Oct. 15.

1918-24. 1928-40: Maximum discharge, 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; minimum, 24 second-feet 

Oct. 21, 1935 (gage height, 0.26 foot): minimum dally, 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 fragmentary or no gage-height record, 

 whTcE are fair. Flow increased by diversion from Shepaug Reservoir Into Naugatuck 

River Basin and also regulated by change in contents in Morris and Wigwam Reservoirs 

(combined capacity, 360,000,000 cubic feet).

HUDSON RIVER BASIN 235

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

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

hatchery, 1 mile downstream from Delta Dam and 4 miles north of Rome, Onelda County. 

Datum of gage is 474.00 feet above mean sea level (Barge Canal datur).

Drainage area.- 150 square miles.

Records avaiiaole.- October 1927 to September 1940 in reports of U. S. Geological Survey. 

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

State engineer and surveyor.

Average discharge.- 19 years (1921-40), 400 second-feet (unadjusted).

Extremes (regulated).- Maximum discharge during year, 2,830 second-feet Apr. 12 (gage 

neignt, eTais reetj; minimum, 87 second-feet Sept. 11-13 (gage height, 1.17 feet): 

minimum dally, 87 second-feet Sept. 12.

1927-40: Maximum discharge, 4,060 second-feet July 9, 1935 (gage height, 8.1 feet, 

from floodmarks); minlnum, 33 second-feet Mar. 3, 1934 (gage height, 0.78 foot); 

minimum dally, 45 second-feet (estimated) Jan. 17, 1931.

Reports of the State engineer and surveyor record a maximum discharge of 4,210 

second-feet Mar. 9, 1921.

Remarks.- Records excellent except those for period computed from grapfr based on gage readings, which are good. During navigation season water Is diverted from Black River 

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

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

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

for use of fish hatchery and later returned to river, part of It above and part below 

gage.

HUDSON RIVER BASIN 237

Mohawk River at Cohoes, N. Y.

Location.- Water-stage recorder, lat. 42°47'051', long. 73°42'2511 , at School street plant 

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

Drainage area.- 3,456 square miles.

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

plant or New York Power & Light Corporation) and October 1925 to September 1940. 

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

Average discharge.- 22 years (1918-40), 5,662 second-feet.

Extremes.- Maximum discharge during year, 63.000 second-feet Apr. 9 (gage height, 18.53 

feet); minimum, 11 second-feet (regulated) Oct. 15 (gage height, 3.60 feet); minimum 

dally, 240 second-feet Sept. 29.

1925-40: Maximum discharge, 130,000 second-feet Mar. 19, 1936 (gage height, 22.57 

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

minimum, probably less than 10 second-feet July 25, 1937; minimum gage height, 3.47 

feet during period Sept. 24 to Oct. 1, 1932; minimum dally discharge, 29 second-feet 

Aug. 2, 1936.

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

which are good. Records Include small diversion Just above gage for Cohoes water 

supply, but not 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), Lanslng Kill, and possibly from Chenango River Basin through Orlskany 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 Schoharle Creek, a trllutary 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, Hlnckley, and Gllboa 

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

by School Street power plant.

figure published In Water-supply Paper 871 In error).

Extremes.- Maximum discharge during year, 35,500 second-feet Mar. 31 (gage height, 16.99 

feet); minimum observed, 122 second-feet Aug. 25 (gage height, 1.55 feet).

1912-40: Maximum discharge, 53,300 second-feet Aug. 24, 1933 (gage helrht, 20.60 

feet), from rating curve extended above 22,000 second-feet by logarithmic Ilotting; 

minimum, 72 second-feet Aug. 4, 5, 1936 (gage height, 1.51 feet).

Flood of Oct. 9, 1903, reached a stage of 23.6 feet, from descriptions obtained In 

April 1939 from local residents who had experienced the flood (discharge, ebout 70,000 

second-feet, from present rating curve extended above 22,000 second-feet by logarithmic 

plotting).

Remarks .-Records excellent except those for periods of Ice effect or for periods when the 

stage was below elevation of Intake pipe, which are fair.

402 SU8QUEHANNA RIVER BASIN

Sage Brook near South New Berlin, N. Y.

Location.- Hater-stage recorder and concrete control with V-notch weir, lat. 4£°31'55", 

long. 75°25'30", 14 miles upstream from mouth and 24 miles west of South New Berlin, 

Chenango County. Datum of gage is 1,430.17 feet above mean sea level (general adjustment of 1912; levels by New York State Department of Conservation).

Drainage area.- 0.70 square mile.

Records available.- November 1932 to September 1940.

Extremes.- Maximum discharge during year, 49 second-feet Mar. 31 (gage heigl*,, 3.40 feet); 

minimum, 0.010 second-foot Oct. 10 (gage height, 1.095 feet).

1932-40: Maximum discharge, 201 second-feet July 8, 1935 (gage height, 4.71 feet), 

from rating curve extended above 22 second-feet on basis of theoretical rating for 

artificial control; minimum, 0.0002 second-foot Sept. 19, 20, 1939.

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

which are good. This station Is being operated In Connection with a stuc'y of the effect of reforestation on stream flow. In addition to records of stream flow records 

of precipitation, temperature, and ground-water levels are being collected. Weekly 

records of ground-water levels have been published In Water-Supply Paper 906.

438 SUSQUEHANNA RIVER BASIN 

Cohocton River near Campbell, N. YJ.

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

 hTihwSy bridge and 2 miles upstream from Campbell, Steuben County. Datun of gage is

I,016.58 feet above mean sea level (general adjustment of 1912). 

Drainage area.- 472 square miles. 

Records available.- July 1918 to September 1940. 

Average aiscnargeT- 22 years (1918-40) 435 second-feet. 

Extremes.- Maximum discharge during year, 12,000 second-feet Apr. 1 (gage height, S.15

 feet); minimum, 30 second-feet Oct. 17 (gage height, 0.58 foot, backwater from weeds). 

1918-40: Maximum discharge, 41,100 second-feet (revised) July 8, 1935 (gage height,

II.6 feet, from floodmarks), .from combination of velocity-area and slope-area studies 

and logarithmic plotting; minimum, 8 second-feet Sept. 6, 7, 1934. 

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

 aTverted from Mud Creek, a tributary above this station, for development of power on 

Keuka Lake; this diversion probably takes all the ordinary flow from the 45 square 

miles of drainage area above Lake Lamoka outlet.

Revisions.- Revised figures of discharge, In second-feet, for the high-water period In

 the water year, 1935, superseding those published In Water-Supply Papers 773-E, 781 

are given herein.
