SURFACE WATER SUPPLY OF NORTH ATLANTIC SLOPE BASINS, 1939

SCOPE OF WORK

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

and flow made on streams, lakes, and reservoirs In the United States during the water yea] 1 

ending September 30, 1939. The work was begun in 1888 in connection with special studies 

relating to irrigation. Measurements of flow of streams and measurements of stage and contents of lakes and reservoirs have been made at about 8,240 gaging stations in the United 

States and' also at many gaging stations In Alaska and Hawaii. In July 1939, 4,160 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. Acknowledgments for cooperation of the first kind are made In connection with the description of each station 

affected; cooperation of the second kind Is acknowledged on page 9.

DEFINITION OF TERMS

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

herein are defined as follows:

"Second-feet" Is an abbrelvatlon for "cubic feet per second." A second-foot Is the ra^ 

of discharge of water flowing In a channel when the cross-sectional area is l square foot 

and the 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 run-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 

flowing 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," equivalent to 43,560 cubic feet, is the quantity of water required to 

cover an acre to the depth of 1 foot. The term is commonly used In connection with storage 

for irrigation.

"Second-foot-day" is the volume of water represented by a flow of 1 second-foot for 24 

hours. It Is equivalent to 86,400 cubic feet, 1.983471 acre-feet, on 646,317 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 the natural section or reach of the channel or 

artificial structure below the gage that determines the stage-discharge relation at the 

gage.

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 gage heights and discharge

1
2 EXPLANATION OF DATA

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

direct readings on a nonrecordlng 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. Gaging station structures 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 are computed.

The data presented for each gaging station In the area covered by this report usually 

eompilse 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 of the year was 

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

The description of the station gives the type of gage, Its latitude and longitude determined from the best available maps, and Information In regard to diversions that 

decrease the flow at the gage, artificial regulation from 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 dally 

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

minimum gage height (except when 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 represents the 

lowest discharge, 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 Is generally 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 nonrecordlng 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 

gage height 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 the mean dally discharge from a continuous gageheight graph and containing as an essential element the rating curve of the station.

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 dally discharge. The 

column headed "Maximum" gives the maximum dally discharge and not the discharge when the 

water surface was at crest height. Likewise, In the column headed "Minimum" the quantity

EXPLANATION OF DATA 3

given is the minimum dally discharge. The column headed "Mean" 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 the statement In regard to the general accuracy of the 

records. "Excellent" Indicates that, In general, the dally records are accurate within 5 

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

higher percent.

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

owing to diversions, amount consumed, 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 reservoir 

records are Included indicating the extent of the regulation, or satisfactory adjustments 

can be made for changes in contents of reservoirs or for other, changes incident to use and 

control. Figures of second-feet per square mile and run-off In Inches are also omitted if 

the drainage area includes large noncontrlbutlng areas or If the average annual rainfall 

over the drainage area Is less than 20 Inches.

Many gaging stations on streams In the irrigated areas of the United States are situated above most of the diversions from those streams, so that 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 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 may be warranted with the Increase In data and the use of Improved 

equipment.

Note.- The reports that contain records for years after 1901 are given In the table on 

page 6.

The table on the following page gives, by years and drainage basins, the numbers of 

the papers on surface water supply published from 1899 to 1939. The data for any par-, 

ticular 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 years.

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

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

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

end of each report, the streams and points of measurement listed appearing in the same 

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

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

vegetation, July 6 to Sept. 23 (computed on basis of three discharge measurements and 

gage heights), which are good. Flow regulated by storage in North Twin and Rlpogenus 

Lakes, on West Branch of Penobscot River (combined capacity, 45,000,000,000 cubic 

feet). Water-stage recorder graphs and results of many winter measurements furnished

Location.- Water-stage recorder, lat. 45°10'55", long. 68°37'20", In Passadumkeag, Penobscot county, at head of Passadumkeag Rips, and 1,200 feet downstream from Passadumkeag 

River. Zero of gage Is 123.6 feet above mean sea level (preliminary adjustment).

Drainage area.- 7,000 square miles (Including about 240 square miles drained by Chamberlain Lake through Telos Canal).

Records available.- November 1938 to September 1939.

Extremes.- Maximum discharge during period, 52,800 second-feet May 10, 11 (gage height, 

9.38 feet); minimum, 3,250 second-feet Sept. 6 (gage height, 2.77 feet).

Remarks.- Records excellent except those for periods of Ice effect, Nov. 27 to Dec. 4, 

Dec. 20 to Apr. 19 (computed on basis of weekly discharge measurements at Costlgan, 

13.5 miles downstream, and gage heights), and those for period of backwater caused by 

aquatic vegetation, July 31 to Sept. 1 (computed on basis of four discharge measurements and gage heights), all of which are good. Flow regulated by storage In North 

Twin and Rlpogenus Lakes, on West Branch of Penobscot River (combined capacity, 

45,000,000,000 cubic feet). Results of many winter discharge measurements furnished 

by T. W. Clark, hydraulic engineer, of Old Town.

Average discharge.- 11 years (1907-9, 1930-39), 4,348 second-feet (adjusted for storage).

Extremes.- Maximum discharge during year, 24,800 second-feet May 10 (gage height, 11.16 

feetj; minimum dally discharge, 1,400 second-feet Dec. 26.

1907-10. 1930-39: Maximum discharge, 55,200 second-feet Mar. 20, 1936 (gage height, 

14.44 feet), based on extension of rating curve above 16,600 second-feet to peak flow 

at Wyman Dam plus Inflow; minimum dally discharge, 770 second-feet Dec. 25, 1937.

Remarks.- Records excellent except those for periods of Ice effect Jan. 26 to Feb. 3, Feb.

 10, 16, 17, 23, Mar. 2, 3, 7-9, 11, 20, 22, 23, which were computed on basis of records 

of power plant upstream and are good. Flow regulated by storage In Moosehead, Brassua, 

and Moxle Lakes, and First Roach and Second Roach,, Dead River, Spencer, and Wyman 

Ponds (combined capacity about 37,523,000,000 cubic feet, revised). Considerable diurnal fluctuation caused by operation of power plant upetream.

66 MERRIMACK RIVER BASIN

Merrlmack River below Concord River, at Lowell, Mass.

Location.- Water-stage recorder, lat. 42°38'50", long. 71°18'0511 , at Lowell, Middlesex 

County, 1,100 feet downstream from Concord River. Zero of gage is 5.18 feet above 

mean sea level.

Drainage area.- Total above gage, 4,635 square miles; net above gage, 4,425 square miles 

(Boston Metropolitan District and City of Worcester divert flow from 210 square miles). 

Prior to July 1, 1937, net above gage, 4,424 square miles (Boston Metropolitan District 

and City of Worcester diverted flow from 211 square miles).

Records available.- June 1923 to September 1939.

Average discharge?- 16 years, 7,253 second-feet (adjusted for wastage into Merrlmack).

Extrernes.- Maximum discharge during year, 48,600 second-feet Apr. 21 (galge height, 51.56 

feet); minimum daily discharge, 574 second-feet (regulated) Sept. 24.

1923-39: Maximum discharge, 173,000 second-feet Mar. 20, 1936 (gage height, 68.4 

feet, from floodmarks); minimum daily discharge, 199 second-feet Sept. 23, 1923.

Remarks.- Records good. Discharge for days of ice effect, Jan. 22, 23, 26, computed

on basis of gage heights, weather records, and records for stations on nearby streams. 

Boston Metropolitan District and City of Worcester divert water from basins of Sudbury 

and South Branch of Nashua Rivers and from Lake Cochltuate; discharge at this station 

includes water wasted from these diversions. Flow partly regulated by operation of 

power plants and storage in Wlnnipesaukes, Squam, Newfound, and other lakes.

Rating table, water year 1938-39 except periods of loe effect (gage height, In feet, and 

discharge, In second-feet)

1929).

Drainage area.- 227 square miles (not including 23.6 square miles drained by Stony Brook).

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

equivalent to figures of unadjusted discharge at present site) and August 1931 to September 1939.

Extremes.- Maximum discharge during year, 1,020 second-feet Apr. 3, 7 (gage height, 3.26 

feet); minimum, 10 second-feet (regulated) June 15,-18 (gage height, 0.52 foot).

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

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

NOV. 28-30 (computed on basis of recorded range of stage), those for days of ice effect, 

Jan. 23, 25, 26 (computed on basis of recorder graph and records for nearby stations), 

and those for period of shifting-control, Oct. 1 to Nov. 9, which are good. Flow of 

Stony Brook, a tributary above station, is diverted for municipal supply of Cambridge;

Extremes.- Maximum discharge during year, 4,980 second-feet Dec. 7 (gage height, B.b

 feet); minimum, 20 second-feet July 30 (gage height, 1.68 feet); minimum dally discharge, 48 second-feet July 23. , . . ..

1904-5: 1933-39: Maximum discharge, 52,200 second-feet Sept. 21, 1938 (gage height, 

27.6 feet, from floodmarks), by computation of flow over spillways of Scotland and 

Baltic Dams, 5 and 9 miles downstream, respectively, and adjusted for flow from intervening area; minimum, 16 second-feet Aug. 19, 1935 (gage height, 1.39 feet), and Oct. 

£0, 1935 (gage height, 1.3E feet); minimum dally discharge, 26 second-feet Aug. 18,

Natchaug River at Willimantic, Conn.

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

from New York, New Havei» & Hartford Railroad bridge, 1 mile northeast of Willimantic, 

Windham County, and li miles upstream from mouth. Zero of gage is 150.31 feet above 

mean sea level (general adjustment of 1929).

Drainage area.- 169 square miles.

Records available.- October 1930 to September 1939.

Extremes.'- Maximum discharge during year, 2,530 second-feet Feb. 16 (gage height, 7.6 

 feet); minimum, 4.S second-feet Aug. 16, 17 (gage height, 1.45 feet); minimum daily 

discharge, 5.0 second-feet Aug. 17.

1930-39: Maximum discharge, 32,000 second-feet Sept. 21, 1938 (gage height, 16.39 

feet, from floodmarks), by computation of flow over dam. 2 miles upstream; minimum, 

about 0.3 second-foot Aug. 6, 1937; minimum daily, about 2.9 second-feet Aug. 6, 1937.

Remarks.- Records good except those for days of ice effect, Jan. 16, 23, which were computed on basis of gage heights and weather records and are fair. City of Willimantic 

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

from reservoir 2 miles above station, operation of water wheels causes diurnal fluctuation during low flow.

100 THAMES RIVER BASIN

Five Mile River at Klllingly, Conn.

Location.- Water-stage recorder, lat. 41°50'10", long. 71°53'09", at northwest abutment 

or New York, New Haven & Hartford Railroad bridge, five-eighths of a mile south of 

Klllingly, Wlndham County, and 2.7 miles upstream from mouth.

Drainage area.- 5S.2 square miles.

Records available.- November 1937 to September 1939.

Extremes.- Maximum discharge during year, 690 second-feet Apr. 20 (gage height, 4.1 

reet); minimum, 3.6 second-feet Sept. 22 (gage height, 0.46 foot); minimum daily discharge, 4.4 second-feet Aug. 13.

1937-39: Maximum discharge, 2,480 second-feet July 24, 193S (gage height, S.52 

feet); minimum, that of Sept. 22, 1939; minimum daily discharge, that of Aug. 13, 

1939.

Peak discharge of flood of Mar. 12, 1936, about 1,600 second-feet (by computation 

of flow over dam at Danielson).

Revisions.- The minimum discharge for the period November 1937 to September 193S 

has been revised to 4.2 second-feet Nov. 8 (gage height, 0.51 foot), superseding 

figure published In Water-Supply Paper S51.

Remarks.- Records good except those for periods of Ice effect, Nov. 27, Jan. 23, 25, 26, 

30, Feb. 17 (computed from gage-height graph corrected for Ice effect) and those for 

days of faulty gage-height record, which are poor. Diurnal fluctuations during low 

flow caused by mills above station.

Rating tables, water year 1938-59 except periods of Ice effect (gage height, in feet* and 

discharge, in second-feet)

104 CONNECTICUT RIVER BASIN

Connecticut River at North Stratford, N. H.

Location.- Water-stage recorder, lat. 44°44'55", long. 71°37'55", at North Stratford, 

coos county, 400 feet downstream from Nulhegan River. Zero of gage Is 880.00 feet 

above mean sea level.

Drainage area.- 796 square miles.

Records available.- August 1930 to September 1939.

extremes.- Maximum discharge during year, 13,700 second-feet May 8; maximum gage height, 

10.41 feet Apr. 22 (Ice Jam); minimum dally discharge, 154 second-feet Sept. 27.

1930-39: Maximum discharge, 28,400 second-feet Mar. 19, 1936, from rating curve 

extended above 16,000 second-feet; maximum gage height, 16.66 feet Mar. 13, 1936 (Ice 

Jam); minimum dally discharge, 150 second-feet Sept. 11, 1930.

Remarks.- Records excellent except those below 300 second-feet, which are good, and those 

ror periods of Ice effect, Dec. 3-7, Dec. 23 to Apr. 22 (computed on basis of gage 

heights, weather records, and records for stations at First Connecticut Lake and near 

Dalton), and those for days of no gage-height record, Nov. 26, 27 (computed on basis 

of records for stations at First Connecticut Lake and near Dalton), which are fair. 

Some diurnal fluctuation at low stages caused by power plant above station. Flow 

regulated by storage In First Connecticut and Second Connecticut Lakes, which have a 

combined usable capacity of 3,840,000,000 cubic feet.

CONNECTICUT RIVER BASIN 105

Connecticut River near Dalton, N. H.

Location.- Water-stage recorder, lat. 44°24'35", long. 71°43'00", 800 feet downstream

 from dam of Oilman Paper Co. and li miles downstream from Dalton, Coos County. Zero

of gage Is 799.89 feet above mean sea level (general adjustment of 1929). Zero of

gage used prior to June 30, 1937, was 800.08 feet above mean sea level (general

adjustment of 1929). 

Drainage area.- 1,538 square miles. 

Records available.- January 1935 to September 1939. March 1927 to September 1935, at

waterrora, lo-ft miles downstream, at which site drainage area Is 1,603 square miles;

records equivalent. 

Average discharge.- 12 years, 3,121 second-feet (adjusted for change In reservoir contents). 

Extremes.- Maximum discharge during year, 23,600 second-feet Apr. 23 (gage height, 18.82

feet); minimum dally discharge, 320 second-feet (regulated) Sept. 24.

1935-39: Maximum discharge, 48,300 second-feet Mar. SO, 1936 (gage height, 25.6

feet); minimum dally discharge, about 80 second-feet (regulated) Sept. 2, 1935. 

Remarks.- Records good except those for periods of Ice effect and periods of missing

 gage heights, which are fair. Stage graph for Nov. 27-29, Jan. 31, Feb. 1, 6-8, 12- 

14, 21, 22, July 7, 8 based on twice-daily chain-gage readings. Some diurnal fluctuation. Flow regulated by storage In First Connecticut and Second Connecticut 

Lakes and other reservoirs, which have a combined usable capacity of about 

4,000,000,000 cubic feet.

tChange in contents in First Connecticut and Second Connecticut Lakes (combined usable capacity, 

about 3,800,000,000 cubic feet).
CONNECTICUT RIVSR BASIN

Connecticut River at South Newbury, Vt.

Location.- Water-stage recorder, lat. 44°02'45", long. 72°04'30", just downstream from 

bridge at South Newbury, Orange County, and 4 miles upstream from Walts River. Zero 

of gage Is 374.90 feet above mean sea level.

Drainage area.- 2,825 square miles.

Records available.- July 1918 to September 1939.

Average discharge?- 20 years (1918-21, 1922-39), 5,075 second-feet (adjusted for change 

in reservoir contents).

Extremes.- Maximum discharge during year, 38,100 second-feet Apr. 23 (gage height, 26.6 

feet, from graph based on gage readings); minimum, 276 second-feet Sept. 24 (gage 

height, 0.13 foot).

1918-39: Maximum discharge, 77,800 second-feet Mar. 19, 20, 1936 (gage height, 

38.6 feet, from floodmarks), from rating curve extended above 49,100 second-feet; 

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

Remarks.- Records good except those for periods of ice effect, Nov. 26 to Dec. 2, Dec. 

23 to Apr. 16, which were computed on basis of two discharge measurements, gage 

heights, and records of power plant and are fair. Discharge for Oct. 12 to Nov. 11, 

Apr. 18-20, 23, Aug. 5-9, computed from graph drawn on basis of twice-daily chaingage readings. Slight diurnal fluctuation. Flow regulated by storage ,in First Connecticut and Second Connecticut Lakes, Comerford Station Pond (formerly called Flfteenmile Falls Reservoir), and other reservoirs, which have a combined usable 

capacity of about 5,400,000,000 cubic feet.

Pond, which was formerly called Fifteenmile Falls Reservoir (combined usable capacity, 

5,020,000,000 cubic feet).
CONNECTICUT RIVER BASIN 

Connecticut River at White River Junction, Vt.

107

Location.- Water-stage recorder, lat. 43°38'50", long. 72°18'45", Just downstream from 

railroad bridge at White River Junction, Windsor County, and from mouth of White 

River. Zero of gage is 321.52 feet above mean sea level (general adjustment of 1929). 

Chain gage at upstream side of railroad bridge used during periods when water-stage 

recorder was not operating.

Drainage area.- 4,068 square miles.

Records available.- October 1911 to September 1939.

Average discharge.- 28 years, 7,357 second-feet (adjusted for change in reservoir contents).

Extremes.- Maximum discharge during year, 52,800 second-feet Apr. 26 (gage height, 20.9 

feet, from graph based on gage readings); minimum, 770 second-feet Sept. 24.

1911-39: Maximum discharge, 136,000 second-fset Nov. 4, 1927 (gage height, 35.0 

feet, present site), from rating curve extended logarithmically above 70,000 secondfeet; minimum, 540 second-feet Aug. 21, 1934.

Remarks.- Records good except those for periods of Ice effect, Dec. 1-4, Dec. 28 to Jan. 

6, Jan. 13 to Mar. 12, Apr. 2, which were computed on basis of two discharge measurements, gage heights, weather records, and records for nearby stations and are fair. 

Flow regulated by storage in First Connecticut and Second- Connecticut lakes, Comerford Station Pond (formerly called Fifteenmile Falls Reservoir), and other reservoirs, which have a combined usable capacity of about 5,600,000,000 cubic feet.

tChange in contents of First Connecticut and Second Connecticut Lakes and Comerford Station Pond, 

which was formerly called Fifteenmile Falls Reservoir (combined usable capacity, 5,020,000,000 

cubic feet).
108 CONNECTICUT RIVER BASIN

Connecticut River at Turners Falls, Mass.

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

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

Drainage area.- 7,138 square miles.

Records available.- January 1915 to September 1939.

Average discharge.- 24 years, 11,910 second-feet (adjusted for change in reservoir 

contents).

Remarks.- Discharge computed by summation of flow over and through dam, flow for factones through canal that diverts around dam, and flow through power stations 1 and 

2 of Turners Falls Power & Electric Co. Considerable diurnal regulation caused by 

operation of power plants. Flow regulated by storage in First Connecticut and 

Second Connecticut Lakes, Comerford Station Pond (formerly called Flfteenmile Falls 

Reservoir), Lake Sunapee, four reservoirs In Mascoma River Basin, and other reservoirs, all of which have a combined usable capacity of about 9,000,000,000 cubic 

feet. Records furnished by Turners Falls Power and Electric Co.

Records available.- June 1915 to September 1939.

Average discharge.- 23 years (1915-27, 1928-39), 1,181 second-feet.

Extremes.- Maximum discharge during year, 15,900 second-feet Apr. 22 (gage height, 12.20 

feet); minimum, 77 second-feet Sept. 22 (gage height, 2.43 feet).

1915-39: Maximum discharge, 120,000 second-feet Nov. 4, 1927 (gage height, 29.3 

feet, from floodmarks), by slope-area method; minimum, 19 second-feet June 27, 1923 

(gage height, 2.05 feet).

Remarks.- Records good except those for periods of ice effect, Nov. 26 to Dec. 5, Dec. 24- 

28, Pec. 30 to Jan. 8, Jan. 14 to Apr. 2 (computed on basis of one discharge measurement, gage heights, weather records, and records for nearby stations), and those for 

days of missing gage heights, Nov. 12, 13 (computed on basis of records for nearby 

stations), which are fair. Discharge for Dec. 1 and 6 computed on basis of observer's 

twice-daily readings.

CONNECTICUT RIVER BASIN 119

Sugar River at West Claremont, N. H.

Location.- Water-stage recorder, lat. 43°23'15", long. 72°21'45", Just downstream from 

Redwater Brook, at West Claremont, Sullivan County.

Drainage area.- 269 square miles.

Kecords available.- October 1928 to September 1939.

Average discharge.'- 11 years, 390 second-feet (adjusted for change in contents in Lake 

Sunapee).

Extremes.- Maximum discharge during year, 6,180 second-feet Apr. 20 (gage height, 7.13 

feet;, from rating curve extended above 3,940 second-feet on basis of computation of 

flow over dam at gage heights 10.49 feet and 10.92 feet; minimum, 39 second-feet 

(regulated) Sept. 11 (gage height, 1.02 feet); minimum daily discharge, 48 second-feet 

(regulated) Sept. 10.

1928-39: Maximum discharge, 14,000 second-feet Mar. 19, 1936, by computation of 

flow over dam; maximum gage height, 11.80 feat Mar. 12, 1936 (ice Jam); minimum discharge recorded, 6.5 second-feet (regulated) Sept. 2, 1934 (gage height, 0.61-foot); 

minimum daily discharge, 31 second-feet (regulated) Oct. 12, 1930.

Remarks.- Records good except those for periods of missing gage heights or ice effect, 

Nov. 22-30, Dec. 21 to Jan. 8, Jan. 22 to Feb. 26 (computed on basis of two discharge 

measurements, gage heights, weather records, and records for Smith River near Bristol 

and Black River at North Springfield, Vt.), and those for Oct. 1-31, Dec. 10-E3, May 

9-13, when small corrections on account of partially clogged intake were made to gage 

heights, which are fair. Flow regulated by storage in Lake Sunapee, which has a capacity of 862,000,000 cubic feet. Diurnal fluctuations at low stages caused by operation 

of mills upstream.

feet), from rating curve extended above 2,330 second-feet an basis of computation of 

flow over dams at gage heights 16.4] feet and 17.68 feet; minimum, 8.3 second-feet 

(regulated) Sept. 24 (gage height, 1.63 feet); minimum daily discharge, 17 second-feet 

(regulated) Sept. 7.

1929-39: Maximum discharge, 15,500 second-feet Sept. 22, 1938 (gage height, 17.68 

feet), from rating curve extended above 2,330 second-feet on basis of computation of 

flow over dams at gage heights 16.41 feet and 17.68 feet; minimum daily discharge, 10 

second-feet (regulated) Oct. 17, 1937.

Remarks.- Records good except those for period of ice effect, Dec. 30 to Mar. 27, which 

were computed on basis of two discharge measurements, gage heights, weather records, 

and records for nearby stations and are fair. Diurnal regulation caused by operation 

of mills upstream.

CONNECTICUT RIVER BASIN 

South Branch of Ashuelot River at Webb, near Marlboro, N. H.

125

Location.- Water-stage recorder, lat. 42°52'20", long. 72°12'fJ5", at bridge about 800 feet 

southwest of V/ebb station on Boston & Maine Railroad and about 2i miles south of Marlboro, Cheshire County. Zero of gage is 667.11 feet above mean sea l^vel (general adjustment of 1929).

Drainage area.- 36.0 jquare miles (revised). 

Records available.- November 1920 to September 1939. 

Average discharge.- 18 years (1921-39), 61.2 second-feet.

Extremes.- Maximum discharge during year, 580 second-feet Dec. 6 (computed because of ice 

effect;; maximum gage height recorded, 5.82 feet Feb. 17 (ice jam), but a higher stage 

may have occurred during period of no gage-height record in February; minimum, 1.1 

second-feet (regulated) Sept. 25.

1920-39: Maximum discharge, 5,960 second-feet Sept. 21, 1938 (gage height, 7.89 

feet), from rating curve extended above 3,280 second-feet on basis of contracted-opening and slope-area determinations at gage height 7.89 feet; maximum gage height, 9.70 

feet Mar. 12, 1936 (ice Jam); practically no flow (regulated) Mar. 2S, 1931.

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

which are poor. Flow regulated by several small reservoirs above istatlon.

126 CONNECTICUT RIVER BASIN

Millers River near Winchendon, Mass.

Location.- Water-stage recorder and concrete control, lat. 42°41'00", long. 72°05'05", at 

Nolan Bridge, a third of a mile downstream from Sip Pond Brook and 2 miles west of 

Winchendon, Worcester County. Zero of gage is 826.66 feet above mean sea level (general 

adjustment of 1929).

Drainage area.- 83.0 square miles (revised).

Records available.- June 1916 to September 1939.

Average discharge.- 22 years (1917-39), 145 second-feet.

Extremes.- Maximum discharge, 885 second-feet Apr. 20 (gage height, 7.39 feet); minimum 

dally discharge, 3.4 second-feet Sept. 24.

1916-39: Maximum discharge, 8,500 second-feet Sept. 22, 1938 (gage height,.21.55 

feet, from floodmarks), by computation of flow over dam; practically no flow Sept. 20, 

1918, Jan. 14, 1925.

Remarks.- Records good except those for periods of ice effect and periods of no gage-height 

record, which are fair. Discharge for periods of shifting control because of moss on 

control computed on basis of two discharge measurements and gage heights. Flow regulated by storage in Lake Monomonac and other reservoirs.

CONNECTICUT RIVER BASIN 127

Millers River at Erving, Mass.

Location.- Water-stage recorder, lat. 42°35'40", long. 72°26'20", 0.6 mile upstream from 

WIckett Brook, 2.7 miles downstream from Erving, Franklin County, and 5i miles upstream 

from mouth. Zero of gage is 364.93 feet above mean sea level (general adjustment of 

1929). Oct. 1 to Dec. 31, 1938, staff gage at site 2.7 miles upstream. Zero of gage 

was 438.26 feet above mean sea level (general adjustment of 1929).

Drainage area.- 375 square miles (prior to Jan. 1, 1939, 370 square miles). 

Records available.- August 1914 to September 1939. 

Average discharge.- 25 years, 644 second-feet.

Extremes.- Maximum discharge during year not determined; minimum, 20 second-feet (regulated) Sept. 22; minimum daily discharge, 47 second-feet (regulated) Sept. 24.

1914-39: Maximum discharge, 29,000 second-feet Sept. 22, 1938 (gage height, 13.37 

feet, from floodmarks), mean of two slope-area determinations; practically no flow at 

tines in 1915, 1916; minimum daily discharge, 8 second-feet (regulated) Sept. 6, 1926.

Remarks.- Records good except those for period of ice effect, Jan. 1 to Mar. 5 (computed 

on basis of one discharge measurement, gage heights, weather records, and records for 

stations on nearby streams), those for periods of no gage-height record, Nov. 1 to 

Dec. 10, Dec. 29-31, June 2-6 (computed on basis of weather records and records for 

stations on nearby streams), and those below 300 second-feet, all of which are fair. 

Gage-height graph for Oct. 1-31, Dec. 11-28, Jan. 1 to Mar. 30 based on twice-daily 

staff-gage readings. Shifting-control method used Aug. 12-14, Sept. 7. Diurnal 

fluctuation at medium and low stages caused by operation of power plant upstream.

at Cold Brook ,

tDiversion from 97 square miles in Ware River Basin for supply of Boston metropolitan district.
136 CONNECTICUT RIVER BASIN

Chicopee River at Indian Orchard, Mass.

Location.- Water-stage recorder, lat. 42°09'40", long. 72°30'55", 1,000 feet downstream 

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

from Fuller Brook. Prior to Nov. 1, 1938,'water-stage recorder at Bircham Bend, 1-j 

mlles downstream.

Drainage area.- 688 square miles. Prior to Nov. 1, 1938, 703 square miles.

Records available.- November 1938 to September 1939. August 1928 to October 1938 at site 

at Blrcnam Bend, If miles downstream; records equivalent.

Average discharge.- 11 years, 1,165 second-feet (adjusted for diversion from Ware River 

Basin ana ror change In contents of Quabbln Reservoir).

Extremes.- Maximum dally discharge during year, 4,000 second-feet Apr. 7; minimum dally 

discharge, 32 second-feet Aug. 13.

1928-39: Maximum discharge, about 45,200 second-feet Sept. 21, 1938, by computation of flow over dam; minimum dally discharge, 16 second-feet several times In 

period 1929-31; practically no flow at times.

Remarks.- Records of monthly discharge for October to June and for August are good; other 

records fair except those below 500 second-feet, which are poor. Discharge for Oct. 1 

to Dec. 18 computed on basis of records for Ware River at Qibbs Crossing, Swift River 

at West Ware, and Quaboag River at West Brlmfield; for Dec. 19 to Aug. 8, on basis of 

records of Red Bridge power plant; and for periods of no gage-height record after 

recorder Installation, Aug. 21-23, Sept. 1-9, 11, 14-23, 25-27, on basis of Red Bridge 

power-plant records, partial gage-height graph, and recorded range of stage. Gageheights for Aug. 20, Sept. 12, 13, 24 partly estimated. Diurnal fluctuation caused 

by power plants above station. Water diverted as required for Boston Metropolitan 

District during period Oct. 15 to June 14 of each year, from 97 square miles of drainage area in Ware River Basin. Flow regulated by storage in Quabbln Reservoir on 

Swift River since August 1939 (usable capacity, 53,700,000,000 cubic feet).

Records available.- January 1937 to September 1939.

Extremes.- Maximum discharge during year, 672 second-feet Dec. 6, 7 (gage height, 7.35 

feet), from rating curve extended above 282 second-feet on basis of slope-area and 

contracted-opening determinations at gage height 15.05 feet; no flow Aug. 7, 14-21 

because of construction of regulating d'Ji.

1937-39: Maximum discharge, 6,780 sscond-feet Sept. 21, 1938 (gage height, 15.05 

feet), average of slope-area and contracted-opening determinations; minimum, that of 

Aug. 7, 14-21, 1939.

Remarks.- Records good except those for May 17 to Sept. 27, which are fair. Stagedischarge relation affected by ice Jan. 23, Feb. 16. Discharge for periods of missing 

gage heights, July 5-29, 31, Aug. 1, 8-13, computed on basis of records for Swift 

River at West Ware and Ware River at Cold Brook. Shift ing-control method used Mar. 1 

to May 16, Aug. 7, 14-21, Sept. 22-27. Discharge for July 30, Aug. 2, 3, computed on 

basis of one or more staff-gage readings daily. Flow during summer affected by construction of East Branch regulating dam. Some regulation from natural storage in

northeast of Winsted.

Drainage area.- 216 square miles.

Records available.- September 1929 to September 1939.

Average discharge?- 10 years, 389 second-feet (based on records unadjusted for storage 

prior to OctT 1, 1936).

Extremes.- Maximum discharge during year, 5,070 second-feet Dec. 6 (gage height, 6.8 

feet; minimum, 23 second-feet Sept. 17 (gage height, 0.63 foot); minimum daily discharge, 26 second-feet Sept. 4.

1929-39: Maximum discharge, 37,100 second-feet Sept. 21, 1938 (gage height, 17.95 

feet from floodmarks), 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 Farmlngton River; minimum, 17 second-feet Sept. 28, 1929, and Aug. 1, 1936: minimum 

gage height, 0.63 foot Sept. 17, 1939; minimum dally discharge, 23 second-feet Aug. 1, 

1936.

Remarks.- Records good except those for periods of ice effect, Nov. E5-29, Dec. 16, 17, 

19-22, 24, 29-31, Jan. 1-5, 16-31, Feb. 1-20, and periods of missing gage heights, May 

3-5 and July 14-18, which were computed on basis of discharge measurements, gage heights, 

weather records and records for Farmington River at Tariffville and Naugatuck River 

near Thomaston and are fair. Diurnal fluctuations caused by operation of mills upstream. Flow regulated by change in contents of Otls Reservoir (capacity, 780,000,000 

cubic feet).

II, 12, July 6, 1939; minimum daily discharge, that of Sept. 18, 24-26, 1939.

Flood of Mar. 12, 1936., reached a stage of 9.0 feet, determined by city engineers of 

Hartford from floodmarks (discharge, 5,400 second-feet). Flood of Mar. 21, 1936 reached 

a stage of 10.7 feet, from floodmarks, owing to backwater from Connecticut River.

Remarks.- Records fair. Variable adjustments applied to much of gage-height record during 

year owing to changes in openings in timber control dam and changes in accumulation of 

debris in openings of or on crest of dam; adjustments generally greatest during periods 

of low flow. Discharge for period of ice effect, Dec. 22-26, computed on basis of gage 

heights and weather records. No gage-height record Aug. 14 to Sept. 8.

Discharge, In second-feet, water year October 193S to September 1939

Peak discharge.- Dec. 6 (3 p.m.) 1,830 sec.-ft.
CONNECTICUT RIVER BASIN 153

North Branch of Park River at Hartford, Conn.

Location.- Water-stage recorder and masonry control, lat. 41°47 t 03", long. 72°42'31", 60 

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

3 miles upstream from confluence with South Branch of Park River. Zero 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 1939.

Extremes.- Maximum discharge during year, 865 second-feet Dec. 6; maximum gage height, 7.6 

feet Feb. 15 (backwater from Ice); minimum discharge, 1.5 second-feet Sept. 19, 20 

(gage height, 0.93 foot); minimum daily discharge, 1.6 second-feet Sept. 19, 20, 23, 24.

1936-39: 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, 0.7 second-foot (regulated) Sept. 25, 1937 (gage height, 0.82 foot); minimum daily 

discharge, 0.9 second-foot Sept. 24, 1937.

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

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

curve after adjusting observed stage to equivalent stage for present recording conditions).

Remarks.- Records good except those for periods of ice effect, and those for periods of 

backwater from rocks or trash on control, which were computed on basis of gage-height 

graph and records for South Branch of Park River and Park River at Hartford and are 

fair. Infrequent low-water regulation caused by small mills above station.

feet); minimum, 6.4 second-feet (regulated) Aug. 25 (gage height, 0.62 foot); minimum 

daily discharge, 14 second-feet Aug. 28.

1919-21, 1928-39: Maximum discharge, 5,160 second-feet Sept. 21, 1938 (gage height, 

13.78 feet, from floodmark), from computation of flow over dam Just above gage; 

practically no flow at times when water was held back by dams; minimum daily discharge, 

1.2 second-feet Sept. 2, 1920.

Remarks.- Records excellent except those for period of faulty intake action, Oct. 1-30, 

and those for periods of no gage-height record, Jan. 27, 28, Sept. 11-26, which were 

computed on basis of records for Scantic River at Broad Brook and Willlmantic River 

near South Coventry and are poor. Flow regulated by storage in Shenipsit Lake and 

other smaller reservoirs above station. Shenipsit Lake has a total capacity of about 

4,700,000,000 cubic feet, only part of which is usable.

162 HOUSATONIC RIVER BASIN

Housatonic River at Stevenson, Conn.

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

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

dam of Connecticut Light & Power Co. at Stevenson, Falrfield County. Zero of gage Is 

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

Drainage area.- 1,545 square miles.

Records available.- August 1928 to September 1939.

Average discharge.- 11 years, 2,545 second-feet.

Extremes.- Maximum discharge during year, 17,100 second-feet Dec. 6 (gage height, 12.3 

feet); minimum, 55 second-feet June 2 (gage height, 0.53 foot); minimum daily discharge, 

70 second-feet July 23.

1928-39: Maximum discharge, 69,500 second-feet Mar. 12, 1936 (gage height, 23.5 

feet, from floodmarks), computed on basis of computations of peak flow over Stevenson 

and Derby dams and slope-area determination at gaging station; practically no flow at 

times owing to regulation; minimum dally discharge, practically no flow Oct. 12, 1930.

Remarks.- Records good except those for period of no gage-height record, Oct. 1-13, which 

were computed on basis of power-plant records and are fair. Ordinary river flow completely regulated at Stevenson hydroelectric plant. Flow regulated by storage In Rocky 

River, Stevenson, and Shepaug Reservoirs (combined usable capacity, 6,600,000,000 cubic 

feet) and by slight diversion of drainage from the basin at Shepaug Reservoir.

HOUSATONIC RIVER BASIN 165

Shepaug River at Woodville, Conn.

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

long. 73°17'40", 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 1939.

Extremes.- Maximum discharge observed during year, 1,280 second-feet Dec. 6; minimum, 

2.4 second-feet (regulated) on several days in November, August and September.

1935-39: Maximum discharge observed, 6,000 second-feet Sept. 21, 1938; no flow 

(regulated) at times.

Remarks.- Records good except those for days 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 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 permanent artificial control below dam, which was calibrated with the sharp-crested weir prior to its removal. 

Gages at dam or artificial control read once daily at ordinary stages and more frequently during periods of rapidly changing stage. Water diverted from Shepaug Reservoir for municipal supply of Waterbury. Flow regulated by storage in Shepaug Reservoir, which was put in operation in September 1933 (capacity, 96,000,000 cubic feet). 

Records furnished by Bureau of Engineering, City of Waterbury.

HOUSATONIC RIVER BASIN 167

Pomperaug River at Southbury, Conn.

Location.- Water-stage recorder, lat. 41°28'50", long. 73°13'30", 200 feet upstream from 

highway bridge, three-quarters of a mile west of Southbury, New Haven County, and 5t 

miles upstream from mouth. Zero of gage is 165.64 feet above mean sea level (general 

adjustment of 1929).

Drainage area.- 75.3 square miles.

Records available.- June 1932 to September 1939. July 1913 to December 1916 at site at 

Bennetts Bridge, 5 miles downstream.

Extremes.- Maximum discharge during year, about 2,000 second-feet Feb. 15 (gage height, 8.1 

feet, from partly estimated gage-height graph); minimum, 6.8 second-feet Aug. 12, Sept. 

24 (gage height, 2.45 feet).

1932-39: Maximum discharge, 7,420 second-feet Sept. 21, 1938 (gage height, 16.0 

feet, from floodmarks), based on computation of flow over dam 2 miles downstream; minimum discharge, 5.2 second-feet Aug. 13, 1933, Sept. 30 and Oct. 1, 1935; minimum gage 

height, 2.33 feet Sept. 7, 1936.

Remarks.- Records good except those for periods of Ice effect, faulty Intake action, or no 

gage-height record, all of which are fair. Some regulation at very low water caused by 

mill above station.

feet; minimum, 44 second-feet July 17 (gage height, 0.14 foot); minimum daily discharge, 

50 second-feet (computed) July 23.

1918-24; 1926-39: Maximum discharge, 17,000 second-feet Sept. 21, 1938 (gage 

height, 12.40 feet), from rating curve extended logarithmically above 4,700 second-feet 

and verified by comparison with records for headwater streams; minimum, 24 second-feet 

Oct. 21, 1935 (gage height, 0.26 foot); minimum gage height, that of July 17, 1939;

SAUOATUCK RIVER BASIN 171

Saugatuck River near Westport, Conn.

Location.- Water-stage recorder, lat. 41°10'15", long. 73°22'00", on old Ford Road 

(Clinton Avenue), 400 feet downstream from West Branch of Saugatuck River, 600 feet 

downstream from dam of Dorr Co., and 2 miles north of Westport, Fairfield County.

Drainage area.- 77.5 square miles.

Records available.- September 1932 to September 1939.

Extremes.- Maximum discharge during year, 1,330 second-feet Jan. 6 (gage height, 6.25 

feet); minimum, 0.6 second-feet Aug. 10 (gage height, 2.04 feet); minimum daily discharge, 1.0 second-feet Aug. 11.

1932-39: Maximum discharge, 5,310 second-feet Mar. 12, 1936 (gage height, 11.30 

feet), from rating curve extended above 1,700 second-feet and verified by peak-flow 

determination at Dorr Co.'s dam; minimum, 0.3 second-foot Aug. 13, 1935 (gage height, 

2.04 feet); minimum daily discharge, that of Aug. 11, 1939.

Remarks.- Records good except those for periods of ice effect, Nov. 25-29, Dec. 2, 3, 22, 

23, 26, 31, Jan. 1, 13-28, Feb. 1, 5, 8, 12, 23-25, which were computed on basis of 

gage heights and weather records and are fair. During low and medium stages, Bridgeport Hydraulic Co. diverts the flow from about 17 square miles of Aspetuck River Basin 

for domestic water supply. Occasional low-water regulation caused by Dorr Co.'s dam.

Revisions.- The figures of discharge for Oct. 2 and the month of October as given herein 

are revisions of and supersede those published in Water-Supply Paper 867.

Rating table, water year 1938-39 except periods of ice effect (gage height, in feet, and 

discharge, in second-feet)

192 HUDSON RIVER BASIN

Glens Falls feeder at Olens Falls, N. Y.

Lobatlon.- Slope station, lat. 43°17'30", long. 73°39'55", at upstream end of feeder 

canal at city of Olens Falls, Warren County. Two water-stage recorders determine 

slope from point of diversion from Hudson River at feeder dam to point near first 

lock downstream (lock 13).

Records available.- May 1927 to September 1939.

Remarks.- Records good. Dally discharge determined by use of Chezy formula, variations 

in coefficient C throughout the season being computed from current-meter measurements. Discharge for Nov. 17-29, May C-13 computed from fragmentary gage-height 

record and records of gate operations and head on gates at diversion dam. Discharge for periods of faulty or no gage-height record, May 14-20, 26, Aug. 12, 13, 

Sept. 17-20, computed on basis of slope as determined by estimating the mean 

dally gage height through a comparison of gage-height graphs. Flow regulated In 

accordance with requirements of Champlain Canal and for floating logs. Operation 

of feeder discontinued Nov. 29 and resumed May 6. During period for which no 

diversion Is shown feeder may carry a small flow representing leakage through head 

gates and run-off from area tributary to feeder above station.

Discharge, In second-feet, water year October 1938 to September 1939

198 HUDSON RIVER BASIN 

North Branch of Hoosic River at North Adams, Mass.

Location.- Water-stage recorder and concrete control, lat. 42°42'10", long. 73°05'3511 ,

 at worth Adams, Berkshire County, 0.4 mile downstream from Hudson Brook and li miles 

upstream from mouth. Zero of gage is 820.46 feet above mean sea level (general adjustment of 1929). Prior to Sept. 21, 1938, water-stage recorder at site 100 feet 

upstream at same datum.

Drainage area.- 39.0 square miles.

Records available.- June 1931 to September 1939.

Extremes.- Maximum discharge during year, 2,140 second-feet Dec. 6 (gage height, .6.09 

reet); minimum daily discharge, 7.2 second-feet Sept. 23-26.

1931-39: Maximum discharge, 8,950 second-feet Sept. 21, 1938 (gage height, 12.05 

feet at present site, from floodmarks), by computation-of flow over dam; minimum, 3.8 

second-feet (regulated) Aug. 11, 1933.

Maximum discharge known, 9,980 second-feet sometime in November 1927, by computation of flow over dam.

Remarks.- Rooords good except those for periods of faulty intake action, Oct. 1 to Dec.

 5, Dec. 15 to Mar. 23, July 22-27 (computed on basis of six discharge measurements, 

weather records, and records for Hoosic River at Adams, Mass., Walloomsac River at 

North Bennlngton, Vt., and Batten Kill at Arlington, Vt.), which are poor. Some backwater from ice during winter. Diurnal fluctuations at low stages caused by operation 

of power plant upstream.

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

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

Datum of gage Is 474.00 feet above mean sea level (Barge Canal datum).

Drainage area.- 150 square miles. . , _

Records available.- October 1927 to September 1939 in reports of Geological Survey.

 December mm to September 1926 (prior to July 1921 gage heights only) in reports of

e " 0 U921-59 ) , 405 second-feet (not adjusted for storage)

SoVlec^d-feet July 9, 1935 (gage height 8 1 feet,

from floodmarks): minimum, 33 second-feet Mar. 3, 1934 (gage height, 0.78 foot); minimum dally discharge, 45 second-feet (estimated) Jan. 17, 1931.

Reports of State engineer and surveyor record a maximum discharge or 4,<Jiu seconaRemarks .^Records^excellent . Discharge for period of Incomplete gage-height record, May 

 15=15, computed on basis of partial gage-height graph and gate openings at Delta Dam. 

During navigation season water is diverted from Black River through Forestport feeder 

and Black River canal (flowing south) Into Delta Reservoir above station, now IB 

almost completely regulated by Delta Reservoir (capacity, 2,800,000,000 cubic feet). 

A small quantity is diverted from Delta Reservoir for use of fish hatchery ana later 

returned to river, part of it above gage and part below.

HUDSON RIVER BASIN 201

Mohawk River near Little Falls, N. Y.

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

 from Rocky Rift Dam, 2 miles upstream from East Canada Creek, and 44 miles southeast 

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

level (Barge Canal datum).

Drainage area.- 1,348 square miles.

Records available.- February to April 1901, October 1927 to September 1939. November

 1923 to September 1927 In files of offices of State engineer and surveyor and of State

Department of Public Works. 

Average discharge.- 12 years (1927-39), 2,725 second-feet.

is.- Maximum discharge during year (river iiivot channel uuumcj. only), um.j/, 14,800 j.-±,uuu second-feet ook/unvi-iooi, Mar. m**. 

f,< vgage height, 13.46 feet); minimum (river channel only), 362 second-feet (regulated) 

Sept. 4 (gage height, 4.12 feet); minimum dally discharge (Including canal), 503 

second-feet (regulated) Sept. 3.

1927-39: Maximum discharge (river channel only), 23,200 second-feet Mar. 18, 1936 

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

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

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

Remarks.- Records excellent. Discharge for periods of Ice effect, Dec. 22 to Jan. 6, 

 Jan. 14-17, 20, Jan. 24 to Feb. 18, computed on basis of four discharge measurements, 

gage heights, observer's and engineers' notes, weather records, and records for stations nearby. Records include diversion of water at Rocky Rift Dam Into Barge Canal 

for power and lockage at lock 16, near St. Johnsvllle, During canal-navigation season water Is received from Black River through Black River Canal (flowing south) and 

Lansing Kill and possibly through Orlskany Creek feeder, from Chenango River Basin. 

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 operation of power plants and locks and dams on Barge Canal. Flow partly regulated by 

storage In Delta and Hinckley Reservoirs (combined capacity,' 6,120,000,000 cubic 

feet).

Discharge, in second-feet, water year October 1938 to September 1939

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

Records available.- June 1919 to September 1939 (navigation seasons only).

Remarks.- Records excellent. Feeder diverts from West Canada Creek at Trenton Falls, 

water reaches Barge Canal through Ninemlle Creek. During period for which no diversion Is shown, feeder may carry a small flow made up of leakage through head gates 

and run-off from the area tributary to feeder above station.

Discharge, In second-feat, water year October 1938 to September 1959

HUDSON RIVER BASIN 207

East Canada Creek at Dolgevllle, N. Y.

Location.- Water-stage recorder, lat. 43°06'05", long. 74°46'15", at Dolgevllle, Herkimer 

county, 100 feet downstream from lower highway bridge and 1 mile downstream from 

Spruce Creek. Datum of gage Is 750.00 feet above mean sea level (general adjustment 

of 1912).

Drainage area.- 261 square miles.

Kecorgs available.- September 1898 to December 1909 and January to November 1912(at High 

Falls, 1 mile downstream) and October 1927 to September 1939 In reports of Geological 

Survey. January 1910 to December 1911 and February 1913 to June 1918 (at High Falls) 

In reports of State engineer and surveyor.

Average discharge.- 12 years (1927-39), 642 second-feet. The figure of average discharge 

as published in Water-Supply Paper 851 has been corrected as follows: 11 years 

(1927-38), 646 second-feet.

Extremes.- Maximum discharge during year, 7,230 second-feet Apr. 26 (gage height, 10.31 

feet); minimum, 20 second-feet (regulated), June 7 (gage height, about 5.53 feet).

1927-39: Maximum discharge, 13,100 second-feet Mar. 18, 1936 (gage height, 11.81 

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

there Is no spillage.

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

engineer and surveyor.

Remarks.- Records good except those for periods of Ice effect, Nov. 25 to Dec. 4, Dec. 

Ub to Jan. 9, Jan. 14 to Mar. 24 (computed on basis of five discharge measurements, 

gage heights, weather records, observer's and engineers' notes, and records for other 

stations In Mohawk River Basin), those for period of backwater of unknown origin, 

Oct. 27 to Nov. 24, and those for periods of faulty or no gage-height record, May 

6-12, May 27 to June 1 (computed on basis of record of Inflow Into Inghams Pond below station), all of which are fair. City of Little Falls diverts about 5 secondfeet for municipal supply. Slight regulation caused by storage In Canada Lakes 

(capacity, about 441,000,000 cubic feet). Diurnal fluctuation at low and medium 

stages caused by power plant above station.

Revisions.- Figures of discharge for Oct. 27-31, 1938, contained herein are revisions 

or, and supersede those published In Water-Supply Paper 867.

Discharge, In second-feet, water year October 193S to September 1939

Wanaque River at Greenwood Lake, N. J.

Location.- Water-stage recorder and concrete control, lat. 41°09'31", lotig. 74°20'00", 

70O reet downstream from dam at outlet of Greenwood Lake, at The Glens, Passalc County. 

Zero of gage Is 601.32 feet above mean sea level (New Jersey Geological Survey bench 

mark). Prior to Oct. 31, 1938, water-stage recorder at site 100 feet upstream at same 

datum.

Drainage area.- 27.1 square miles.

Recoras available.- May 1919 to September 1939.

Average aiscflargeT- 20 years, 50.6 second-feet (adjusted for storage subsequent to 1935).

Extremes.- naximum -discharge during year, 344 second-feet Dec. 6, 7 "(gage height, 3.65 

reet}; minimum dally discharge, 7.8 second-feet Nov. 1.

1919-39: Maximum discharge, 914 second-feet Mar. 12, 1936 (gage height, 4.82 

feet), by computation of flow over Greenwood Lake Dam; no flow at times when gates at 

Greenwood Lake were closed and no water passed over spillway.

Remarks.- Records good except those for period when coffer dam was In river channel and 

tnose for period of no gage-height record, all of which are fair. Flow regulated by 

storage In Greenwood Lake (usable capacity, 919,000,000 cubic feet): See record for 

Greenwood Lake at The Glens. Water-stage recorder graph furnished by North Jersey

8,880 sec.-ft. 

 Faulty or no gage-height record; discharge computed on basis of partial recorder graph and 

records for station at Blackmails Hills.

Hote.- Discharge below 271 second-faet computed by shifting-control method.
262 RARITAN RIVER BASIN 

Millstone River at Blaekwells Hills, N. J.

Location.- Water-stage recorder and concrete control, lat. 40 028'30", long. 74°34'34", at 

nignway bridge at Blackwells Mills, Somerset County, a quarter of a mile downstream 

from Middlebrush Brook. Zero of gage is 26.97 feet above mean sea level (general adjustment of 1929).

Drainage area.- 258 square miles.

Records available.- August 1921 to September 1939. June 1903 to December 1904 (gage 

heights only} at site at Millstone, If miles downstream.

Average discharge.- 17 years, (1922-39), 372 second-feet.

Extremes.- Maximum discharge during year, 6,270 second-feet Feb. 4 (gage height, 10.04 

reet;; minimum, 22 second-feet Sept. 23, 24 (gage height, 1.26 feet).

1921-39: Maximum discharge, 18,300 second-feet Sept. 21, 1938 (gage height, 15.29 

feet, from floodmark), from slope-area determination; minimum, about 5 second-feet 

Sept. 16, 1923.

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

record, and those above 1,000 second-feet, all of which are good. Delaware & Raritan 

Canal parallels river for some distance, and there may be a slight amount of water 

diverted from Delaware River to the Millstone River through this canal.

feet), from rating curve extended above 5,000 second-feet by logarithmic plotting; 

minimum, that of Sept. 23, 1939.

Remarks.- Records excellent except those for periods of ice'effect, Dec. 29-31, Jan. 17, 

237~24, Jan. 26 to Feb. 1, Feb. 5, 6, 11-13 (computed on basis of eight discharge 

measurements made during winter, gage heights, weather records, engineers' notes, and 

records for East Branch at Harvard and Beaver Kill at Craigle Clalr), and those for 

periods of shifting control, June 11, 12, July 31 to Sept. 30 (computed on basis of 

four discharge measurements, gage heights, engineers' notes, and records for station 

at Harvard), which are good.

Records available.- October 1934 to September 1939.

Extremes.- Maximum discharge during year, 11,100 second-feet Dec. 6 Uage height, 11.50 

feet); maximum gage height, 13.33 feet Feb. 15 (Ice jam); minimum discharge, 41 secondfeet Sept. 26 (gage height, 1.84 feet).

1934-39: Maximum discharge, 31,400 second-feet Sept. 22, 1938 (gage height, 16.93 

feet), from rating curve extended above 10,000 second-feet on basis of slope-area determination at 26,200 second-feet and by logarithmic plotting; minimum, 34 secondfeet Aug. 4, 1936 (gage height, 1.85 feet); minimum gage height, that of Sept. 26, 

1939.

Remarks.- Records excellent except those for periods of Ice effect, Dec. 28 to Jan. 6, 

Jan. 17 to Feb. 15 (computed on basis of seven discharge measurements made during 

winter, gage heights, weather records, observer's and engineers' notes, and records 

for East Branch at Margaretville and for Beaver Kill at Cralgle Clalr and Cooks Falls) 

which are fair, and those for periods of missing gage heights, Feb. 17-24, Sept. 27, 

28 (computed on basis of records for East Branch at Flshs Eddy and Beaver Kill at 

Cooks Falls), which are good.

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

at Port Jervis, Orange County, 14 miles upstream from mouth of Neverslnk River. Zero

of gage Is 415.35 feet above mean sea level (general adjustment of 1929). 

Drainage area.- 3,076 square miles. 

Kecoras available.- October 1904 to September 1939. 

Average discharge.- 35 years, 5,569 second-feet. 

Extremes.- Maxlnum discharge during year, 55,600 second-feet Dec. 6 (gage height, 11.25

reet;; minimum discharge observed, 325 second-feet Sept. 25 (gage height, 0.95 foot);

minimum dally discharge, 428 second-feet Sept. 4.

1904-39: Maximum discharge, 108,000 second-feet Mar. 18, 1936 (gage height, 17.55

feet), from rating curve extended by logarithmic plotting above 35,000 second-feet;

minimum, 175 second-feet Sept. 22, 23, 1908 (gage height, 0.60 foot); minimum dally

discharge, 175 second-feet Sept. 22, 23, 1908.

Maximum discharge known, about 155,000 second-feet Oct. 10, 1903 (gage height,

23.1 feet, revised, reported by U. S. Weather Bureau), from rating curve extended 

above 60,000 second-feet by logarithmic plotting.

Maximum stage known, 25.5 feet Mar. 8, 1904 (Ice jam).

Remarks.- Records excellent except those for periods of ice effect, Dec. 28 to Jan. 1, 

Jan. 18-20, 26-28 (computed on basis of seven discharge measurements made during 

winter, gage heights, and weather records), and those for July to September, all of 

which are good. Large diurnal fluctuations at medium and low stages caused by operation of power plants on tributary streams. Flow regulated considerably by storage 

in Lake Wallenpaupack and in Toronto and Swinging Bridge Reservoirs (combined 

capacity, 12,200,000,000 cubic feet). Records of storage furnished by Pennsylvania 

Power and Light Co. for Lake Wallenpaupack and by Rockland Light and Power Co. for 

Toronto and Swinging Bridge Reservoirs.

Beaver Kill at Cralgle Clair, N. Y.

Location.- Water-stage recorder, lat. 41°57'45", long. 74°52'00", 100 feet downstream 

rrom highway bridge at Cralgie Clalr, Sullivan County, and 2i miles upstream from 

Spring Brook. Zero of gage is 1,399.69 feet above mean sea level (general adjustment 

of 1912). Prior to Aug. 14, 1937, chain gage on bridge at datum 0.56 foot higher. Drainage area.- 82 square miles.

Records available.- May 1937 to September 1939.

Extremes.- .- Maximum dischargere duringrg year, 3,910 , second-feet eco-ee Dec. e6 (gage gheight, 7.78 . 

reet), from rating curve extended above 2,700 second-feet by logarithmic plotting: minimum, 15 seoond-feet Sept. 24-26; minimum gage height, 2.65 feet July 21.

1937-39: Maximum discharge, 9,530 second-feet Aug. 11, 1938 (gage height, 10.11 

feet), from rating curve extended above 2,700 second-feet by logarithmic plotting; minimum discharge, that of Sept. 26, 1939; minimum gage height, that of July 21, 1939. 

Remarks.- Records excellent except those for periods of ice effect, Nov. 24-27, Dec. 3, 

Dec. 23 to Jan. 5, Jan. 15 to Feb. 15 (computed on basis of eight discharge measurements made during winter, gage heights, weather records, and observer's and engineers' 

notes), and periods of backwater from rock dam, July 25 to Sept. 30 (computed on basis 

of three discharge measurements and observation of change in stage when rocks were removed), which are good.

Rating tables, water year 1933-39 except periods of ioe effect (gage height, In feet,

and discharge. In seoond-feet)

304 DELAWARE RIVER BASIN

Cold Spring Brook at China, N. Y.

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

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

Delaware County. Datum of gage is 1,490.76 feet above mean sea level (general adjustment of 1912; levels by Corps of Engineers, U. S. Army).

Records available.- October 1934 to September 1939.

Extremes.- Maximum discharge during year, 47 second-feet Dec. 6 (gage height, 3.09 feet); 

minimum, 0.020 second-foot July 25, 26 (gage height, 1.125 feet).

1934-39: Maximum discharge, 335 second-feet (revised) Oct. 30, 1935 (gage height, 

4.5 feet, from floodmarks), from rating curve extended above 54.7 second-feet on basis 

of theoretical rating study; minimum, 0.008 second-foot Aug. 3, 1936 (gage height. 

1.075 feet).

Revisions.- The figures of maximum discharge for some water years have been revised, 

as shown In the following table. They supersede those published in the water-supply 

papers indicated.

those for periods of Ice effect, Nov. 11, Dec. 2, 23, 27, 28, Jan. 22-28, Jan. 31 to 

Feb. 3, Feb. 8-12 (computed on basis of one discharge measurement, gage heights, 

inspections and removal of ice from control, weather records, and records for Cherry 

Valley Creek at Westvllle and West Branch of Delaware River at Delhi), those for 

periods of faulty or no gage-height record, July 9, Sept. 13-15 (computed on basis 

of precipitation records and records for nearby stations), and those for periods when 

intake was plugged, Oct. 28, 29, Nov. 19-21 (computed on basis of relation between' 

readings of inside and outside gages, two discharge measurements, and precipitation 

records), all of which are fair. This station is being operated in connection with a 

study of the effect of reforestation on stream flow. In addition to'records of stream 

flow, there are being collected in this basin records Of rainfall, temperature, and

§ round water. Weekly records of ground-water levels have been published in Waterupply Paper 886.

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

to 1938 are given herein. They supersede those published In Water-Supply Papers 773,

County, 300 feet downstream from Wallenpaupack Creek and 1,000 feet downstream from 

highway bridge and former site of gaging station. Zero of gage is 868.74 feet above 

mean sea level (preliminary levels of 1927).

Drainage area.- 290 square miles (not Including that of Wallenpaupack Creek, which Is 

228 square miles, and flow from which is diverted around station to hydroelectric f 

plant downstream. See p. 307).

Records available.- August 1938 to September 1939 in reports of U. S. Geological Survey. 

July 1908 to December 1919 and August 1938 to September 1939 in reports of Pennsylvania 

Department of Forests and Waters.

Extremes.- Maximum discharge during year, 7,200 second-feet Feb. 20 (gage height, 6.71 

feet); minimum, 25 second-feet Sept. 26 (gage height, 1.27 feet); minimum daily discharge, 29 second-feet Sept. 24, 25.

1908-19, 1938-39: Maximum discharge, 11,800 second-feet Sept. 22, 1938 (gage 

height, 7.90 feet), from rating curve extended above 6,000 second-feet; minimum daily 

discharge, 7 second-feet Aug. 20, 1911.

Maximum stage known, about 13.9 feet, from floodmarks, Mar. 18, 1936 (discharge 

not determined).

Remarks.- Records good except those for periods of ice effect, Nov. 26 to Dec. 3, Dec. 

28 to Jan. 5, Jan. 14 to Feb. 15, which were computed on basis of one discharge 

measurement, gage heights, weather records, and records for stations in nearby 

drainage basins and are fair. Some regulation caused by operation of power plant 

upstream.

Creek.

Drainage area.- 52.6 square miles.

Records available.- April 1932 to September 1939.

Extremes.- Maximum discharge observed during year, 2,500 second-feet Aug. 19 (gage height, 

6.93 reet), from rating curve extended above 2,000 second-feet on basis of velocityarea study; minimum observed, 12 second-feet Aug. 11 (gage height, 3.02 feet).

1932-39: Maximum discharge, 10,600 second-feet July 5, 1937 (gage height, 14.5 

feet, from floodmarks), from rating curve extended above 2,000 second-feet on basis 

of velocity-area study; minimum discharge observed, 7 second-feet Sept. 19, 22-24, 

1932 (gage height, 2.09 feet).

Maximum stage known, about 19 feet sometime In June 1884.

Remarks.- Records fair except those for periods of Ice effect, Nov. 25-28, Dec. 28-30, 

Jan. 20-28 (computed on basis of gage heights, weather records, observer's notes, 

and records for Deer Creek at Rocks and Octoraro Creek near Rising Sun), those for 

period of faulty gage-height record, Jan. 10-19, and day of no gage-height record, 

Sept. 24 (computed on basis of records for above-named stations), all of which are 

poor. Slight regulation caused by mills upstream. Gage read twice dally.

discharge, 2,090 second-feet Sept. 24.

1931-39: Maximum discharge, 787,000 second-feet Mar. 19, 1936 (gage height, 60.73 

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

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

In order to obtain current-meter measurements at low water; minimum daily discharge, 

1,380 second-feet Sept. 26, 1932.

SUSQUEHANNA RIVER BASIN 351

Sage Brook near South New Berlin, N. Y.

Location.- Water-stage recorder and concrete control with V-notch weir, lat. 42°31'55", 

long. 75025'30", about 14 miles upstream from confluence with Great Brook and about 

2i miles west of South New Berlin, Chenango County. Datum of gage is 1,430.17 feet 

(revised) above mean sea level (general adjustment of 1912).

Drainage area.- 0.70 square mile (revised).

Kecoras available.- November 1932 to September 1939.

extremes.- Maximum discharge during year, 39.5 second-feet Feb. 20 (gage height, 3.27 

TeeTIT minimum, 0.0002 second-foot Sept. 19, 20 (gage height, 1.015 feet).

1932-39: Maximum discharge, 201 second-feet July 8, 1935 (gage height, 4.71 feet) 

from rating curve extended above 11 second-feet on basis of theoretical rating for 

artificial control; minimum, that of Sept. 19, 20, 1939.

Remarks.- Records good. Discharge for periods of ice effect, Jan. 22-26, Jan. 30, Feb. 

15, computed on basis of one discharge measurement, gage heights, and records for stations on nearby streams; discharge for period of backwater from debris In weir notch, 

Aug. 16-18, computed on basis of one discharge measurement and records for stations 

on nearby streams; discharge for periods of faulty or no gage-height record, Sept. 12, 

26, computed on basis of weather records and records for stations on nearby streams. 

This station Is being operated In connection with a study of the effect of reforestation on stream flow. In addition to records of stream flow there are being collected 

also In this basin records of rainfall, temperature, and ground-water elevations. 

Weekly records of ground-water elevations during year have been published In WaterSupply Paper 886.

SUSQUEHANNA RIVER BASIN 357

Tioughnioga River at Cortland, N. Y.

Location.- Water-stage recorder, lat. 42°36-'10", long. 76°09'35", at upstream side of Elm 

street Bridge at Cortland, Cortland County, and 0.4 mile downstream from confluence 'of 

Sast and West Branches. Zero of gage is 1,088.19 feet above mean sea level (Coast and 

Geodetic Survey unadjusted 1935 levels).

Drainage area.- 296 square miles (including 15.7 square miles whose drainage can be dlvertea into Deruyter Reservoir, In Oswego River Basin).

Records available.- May 1938 to September 1939.

Extremes.- Maximum discharge during year, 4,290 second-feet Feb. 21 (gage height, 6.45 

reet, from reconstructed recorder graph), from rating curve extended by logarithmic 

plotting above 2,000 second-feet; minimum dally discharge, 19 second-feet Sept. 17 and

1938-39: Maximum discharge, that of Feb. 21, 1939; minimum daily discharge, that of 

Sept. 17 and 24, 1939.

Remarks.- Records good except those for periods of missing or incomplete gage-height record, Nov. 25-28, Jan. 28 to Feb. 4, which were computed on basis of records for Tioughnioga River at Itaska and Otsellc River near Upper Lisle and are fair. Discharge during period of Ice effect, Nov. 24-29, Dec. 2, 3, 16, Dec. 22 to Jan. 4, Jan. 14 to Feb. 

6, Feb. 12, 13, 16-18, computed on basis of gage heights, seven discharge measurements 

made during winter, and weather records. Discharge during period of backwater from 

weeds, Aug. 14 to Sept. 30, computed on basis of five discharge measurements and gage 

heights. Diurnal fluctuation at low and medium stages caused by operation of mills 

on West Branch. During the year nearly all the drainage from 15.7 square miles of 

Tioughnioga River Basin was diverted into Oswego River Basin.

Rating table, water year 1938-39 except periods of lee effect or of backwater from weeds 

(gage height, In feet, and discharge, In second-feet)

Location.- Water-stage recorder, lat. 42°17'55", long. 75°54'30", at Itaska, Broome 

Uounty, 3f miles downstream from Otselic River and village of Whitney Point, and six 

miles upstream from mouth. Datum of gage is 917.97 feet above mean sea level (general 

adjustment of 1912).

Drainage area.- 735 square miles.

Records available.- October 1929 to September 1939.

Average discharge.- 10 years (1930-39), 1,179 second-feet.

Extremes.- Maximum discharge during year, 15,300 second-feet Feb. 20; maximum gage

height, 12.16 feet Feb. 20 (ice Jam); minimum discharge, 39 second-feet Sept. 25 (gage 

height, 0.76 foot, affected by backwater from weeds).

1929-39: Maximum gage height, 16.61 feet, from floodmarks, July 8, 1935 (discharge 

as previously published is subject to revision on basis of studies during 1940); minimum discharge, that of Sept. 25, 1939.

Remarks.- Records excellent except those for periods of ice effect, Nov. 24-29, Dec. 2, 3, 

15-17, Dec. 22 to Jan. 6, Jan. 14 to Feb. 20 (computed on basis of nine discharge 

measurements, gage heights except Feb. 19, 20, weather records, and comparison with 

the records for Tioughnioga River at Cortland, Otselic River near Upper Lisle, and 

Dudley Creek at Lisle), those for periods of backwater from weeds, Oct. 1-18, and June 

16 to Sept. 30 (computed on basis of seven discharge measurements, gage heights, and 

comparison with the sum of the records at three upstream stations), those for period 

of faulty or missing gage heights, June 11, 12 (computed on basis of partial gage 

heights, weather records, and records for Tloughnioga River at Cortland, Otselic River 

near Upper Lisle, and Dudley Creek at Lisle), which are good.

Discharge, In second-feet, water year October 193S to September 1939

SUSQUEHANNA RIVER BASIN 359

Shackham Brook near Truxton, N. Y.

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

00", long. 76°01'10", about a quarter of a mile downstream from confluence of two 

branches of brook, about three-quarters of a mile upstream from confluence of brook 

with Labrador Creek, and about 5 miles north of Truxton, Cortland County. Datum of 

gage Is 1,881.52 feet above mean sea level (general adjustment of 1912; levels by 

Corps of Engineers, U. S. Army).

Drainage area.- 3.12 square miles.

Records available.- November 1932 to September 1939.

Extremes.- naxlmum discharge during year, 155 second-feet Feb. 20 (gage height, 3.74 feet); 

minimum, 0.075 second-foot Septi 25, 26 (gage height, 1.23 feet).

1932-39: Maximum discharge, 360 second-feet Oct. 23, 1937 (gage height, 4.43 feet), 

from rating curve extended above 94 second-feet by logarithmic plotting; minimum, 0.065 

second-foot Aug. 11, 1934 (gage height, 1.22 feet).

Remarks.- Records good except those for periods of Ice effect, those for periods of backwater from rock and debris on control, and those for periods of no gage-height record, 

all of which are fair. This station Is being operated In connection with a study of 

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

there are being collected also In this basin records of rainfall, temperature, humidity, 

barometric pressure, soil temperature, and ground-water elevations. Weekly records of 

ground-water elevations during year have been published In Water-Supply Paper 886.

374 SUSQUEHANNA RIVER BASIN

Canlsteo River at Arkport, N. Y.

Location.- Water-stage recorder and concrete control, lat. 42°23'45", long. 77°42'50",

 about 1,000 ft. downstream from Arkport flood-control dam and 0.9 mile west of Arkport, 

Steuben County. Zero of gage Is 1,202.10 feet above mean sea level (general adjustment of 1912), furnished by Corps of Engineers, U. S. Army.

Drainage area.- 30.5 square miles.

Records available.- January 1937 to September 1939.

Extremes,- Maximum discharge during year, about 2,000 second-feet Feb. 20, maximum gage

 height, 5.63 feet Feb. 19 (Ice Jam); minimum discharge, practically no flow Sept. 30 

(gage height, 0.58 foot, affected by construction operations).

1937-39: Maximum discharge, 2,000 second-feet Mar. 5, 1938, and Feb. 20, 1939; 

minimum, practlca-lly no flow July 30, 1938, and Sept. 30, 1939 (affected by construction operations). Maximum discharge known, 4,820 second-feet sometime during flood of July 8, 9, 1935, 

by slope-area method. 

Remarks.- Records good except those for periods of Ice effect, Nov. 24-28, Dec. 2, 14-17,

 2~2"7~23, Dec. 25 to Jan. 5", Jan. 13 to Feb. 20, Feb. 22-28, Mar. 2, 3, 8-15, 17-23 

(computed on basis of seven discharge measurements made during winter, gage heights, 

weather records, and records for nearby stations), those for periods of backwater from 

debris on control, Oct. 29 to Nov. 7, June 16-22, 25, 26 (computed on basis of three 

discharge measurements and records for Karr Valley Creek at Almond and Canlsteo River 

at Hornell), and those for below 1.0 second-feet, all of which are fair. During the 

year construction of the Arkport flood-control dam, a short distance upstream caused 

some regulation of low flows, and a considerable part of low flow was pumped from 

stream for use In construction.

Drainage area.- 27.6 square miles.

Records available.- February 1937 to September 1939.

Extremes.- Maximum discharge during year, 1,900 second-feet Feb. 20 (gage height, 4.42 

feet, backwater from Ice); maximum gage height, 4.96 feet Feb. 15 (Ice Jam); minimum 

discharge, practically no flow for several hours on Aug. 15, 16, 17 (gage height, 

1.03 feet).

feet), from rating curve extended by logarithmic plotting above 1,600 second-feet: 

minimum, that of Aug. 15, 16, 17, 1939.

Remarks.- Records excellent except those for periods of Ice effect, Nov. 25-28, Dec. 15, 

IBT~22-24, 28-31, Jan. 2, 3, Jan. 14 to Feb. 15, Feb. 17, 19, 20, Mar. 8, 11, 18, 19 

(computed on basis of two discharge measurements, gage heights, and weather records), 

those for periods of backwater from leaves on control, Sept. 10-15, 17, 20-23 (computed by shifting-control method on basis of engineer's Inspection, weather records, 

and records for Canacadea Creek at Hornell), and those below 2 second-feet, all of 

which are fair.

Rating tables, water year 193S-39 except periods of ice effect (gage height, in feet,

and discharge* in second-feet)

382 SUSQUEHANNA RIVER BASIN

Cohocton River near Campbell, N. Y.

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

highway bridge that is 2 miles upstream from Campbell, Steuben County. Zero of gage 

is 1,016.58 feet above mean sea level (general adjustment of 1913).

Drainage area.- 472 square miles.

Records available.- July 1918 to September 1939.

Average discharge!"- 21 years, 431 second-feet.

Extremes.- Maximum discharge during year, 10,600 second-feet Feb. 20 (gage height, 7.82 

feet); maximum gage height, 8.15 feet Feb. 20 (ice Jam); minimum daily discharge, 20 

second-feet Sept. 19 (gage height, 0.57 foot, backwater from weeds).

discharge measurements, gage heights, weather records, engineers' and observer's notes, 

and records for stations on other streams in Cohocton River Basin), those for period 

of backwater from weeds May 26 to Sept. 30 (computed-on basis of oeven discharge 

measurements), and those for period of fragmentary or missing gage-height record, 

Feb. 24, 25 (computed on basis of available gage heights and records for other stations in Cohocton River Basin), all of which are fair. Water is diverted 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 Lamoka Lake outlet.

feet, from floodmarks in gage shelter), by slope-area method: minimum. 52 second-feet 

Oct. 17, 18, 1930.

Maximum stage known prior to 1911, 23.0 feet, present site, June 1, 1889 from 

floodmarks (discharge, about 71,300 second-feet).

Remarks.- Records good except those for periods of ice effect, Nov. 24-29, Dec. 16 to 

Jan. 2, Jan. 19-31, which were computed on basis of gage heights, weather records, 

and records for stations on nearby streams, and are poor. Some regulation at low 

stages caused by operation of power plants upstream.

^Discharge measurement.
410 SUSQUEHATOW RIVER BASIN

Dunning Creek at Yount, Pa.

Location.- Chain gage, lat. 40°03'30", long. 78°28'30", at highway bridge at Yount, Bedford County, 3 miles upstream from mouth and 3i miles northeast of Bedford. Zero of 

gage Is 1,046.43 feet above mean sea level (preliminary levels of 1935).

Drainage area.- 191 square miles.

Records available.- October 1931 to September 1939 In reports of U. S. Geological Survey. 

November 1929 to September 1939 In reports of Pennsylvania Department of Forests and 

Waters (discontinued).

Extremes.- Maximum discharge during year, 3,900 second-feet Feb. 4 (gage height, 8.3 

feet, from graph based on gage readings), from rating curve extended above 1,700 

second-feet; minimum discharge observed, 14 second-feet Oct. 4 (gage height, 0.52 foot); 

minimum dally discharge, 16 second-feet Oct. 3-5.

1929-39: Maximum discharge, 17,900 second-feet (estimated) Mar. 18, 1936 (gage 

height, 18.08 feet, from floodmark, affected by backwater from Raystown Branch of 

Juniata River); minimum discharge observed, 4.9 second-feet July 28, 1930 (gage height, 0.46 foot).

Remarks.- Records fair except those for periods of ice effect, Nov. 25-29, Dec. 16 to 

Jan. 1, Jan. 14-30 (computed on basis of two discharge measurements, sage heights, 

weather records, and records for stations on nearby streams), and those for periods 

of missing or doubtful gage heights, May 23-25, Sept. 5, 29, 30 (computed on basis of 

records for stations on nearby streams), all of which are poor. Gage read twice dally. 

Slight regulation at low stages caused by operation of power plants upstream.

Zero of gage is 648.23 feet above mean sea level (Corps of Engineers, U. S. Army, bench 

mark). Prior to Dec. 10, 1938, wire-weight gage on highway bridge 250 feet downstream 

at same datum.

Drainage area.- 596 square miles.

Records available.- October 1938 to September 1939.

Extremes.- Maximum discharge during year, 20,200 second-feet Feb. 3 (gage height, 16.65 

feet); minimum, 62 second-feet Sept. 28; minimum gage height, 0.45 foot Oct. 19.

Flood of Mar. 17, 1936, reached a stage of about 23.5, from floodmarks (discharge, 

about 50,000 second-feet).

Remarks.- Records good except those for periods of ice effect, Nov. 28-30, Dec. 28-31, 

which were computed on basis of gage heights, weather records, and records for stations 

at Bloomlngton and near Cumberland and are fair. Low-water flow affected by operation 

of reservoir on Stony River, about 66 miles above station (capacity, about 265,000,000 

cubic feet).

YEARLY-DISCHARGE SUMMARY 

Part 1. North Atlantic slope basins

489

The following tables summarize In convenient form for general reference and for use In 

preliminary Investigations the figures of yearly discharge and run-off for certain gaging 

stations in the North Atlantic slope basins, previously published In the annual series of 

water-supply papers. All gaging stations, both active and discontinued, at which 10 or 

more complete years of record have been collected and published are represented. Also, an 

Incomplete year is included if the maximum dally discharge or minimum daily discharge for 

all years of record occurred in that year. The summaries present figures of maximum and 

minimum dally discharge and yearly mean discharge and run-off, for both the water years 

ending September 30 and the calendar years. The figures for the water years prior to 1914 

and figures for the calendar years 1914 to 1933 have not been previously published in the 

annual water-supply papers but are included in these summaries.

The number of the water-supply paper in which the figures of dally and monthly discharge as well as yearly discharge are published Is shown in the column headed W. S. P. 

(no. and page). The descriptions contained in the water-supply papers indicated give 

detailed information relative to the gaging stations, including location, diversions, regulation by storage, and other pertinent information. Records for stations which were 

operated prior to 1901 are generally contained in the annual reports of the Geological 

Survey. Reference is made to these reports if records have not also been published in 

water-supply papers.

Figures of drainage area are given for each station when known. These figures have 

been revised from time to time as more accurate maps have become available. The discharge 

per square mile and run-off in inches in the following tables, In general, have been 

revised according to the latest figure for the drainage area.

For summaries after 1914 if the period extends beyond September 30, recoils of daily and 

monthly discharge after that day are contained in the water-supply paper indicated for the 

following year.

Former names under which records for some of the stations have been published in the 

annual water-supply papers are indicated in these yearly summaries as follows:

1. If the name of the stream or town or other feature to which trie stat'on is referred 

has been changed, the former name is given In parentheses, indicating that records for

some of the earlier years are published under the obsolete name. #

2. If the entire name of a station has been changed, the superseded name and years 

when it was used are given in parentheses beneath the present name.
