SURFACE WATER SUPPLY OP NORTH ATLANTIC BASINS, 1950

SCOPE OP WORK

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

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

water year ending September 30, 1950. The work was begun in 1888 in connection with 

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

stage and contents of lakes and reservoirs have been made at about 12,060 gaging stations 

in the 48 States and also at many in the Territories of Alaska and Hawaii. On September 

30, 1950, 6,540 gaging stations, including those in Hawaii and Alaska were being maintained by the Geological Survey-and cooperating organizations. Miscellaneous discharge 

measurements were made during the water year at many other points.

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

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

kind is acknowedged in connection with the description of each station affected; cooperation of the second kind is acknowledged, under the heading "Cooperation," in the introductory matter that precedes the gaging-station records in each volume. In the present 

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

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 abbreviation for "cubic feet per second." A second-foot is the 

rate of discharge of a stream whose channel is 1 square foot in cross-sectional area and 

whose average velocity is. 1 foot per second.

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

second from each square mile of area drained, on the assumption that the runoff is distributed uniformly both as regards time and area.

"Runoff in inches" is the depth to which an area would be covered if all the water 

draining from it in a given period were uniformly distributed on its surface. It is used 

for comparing runoff with rainfall, which is usually expressed in inches.

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

1 foot and is equivalent to 43,560 cubic feet. The term is commonly used in connection 

with storage for irrigation.

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

hours. It is equivalent to 86,400 cubic feet, 1.983471 acre-feet, or 646,317 gallons and 

represents a runoff of 0.0372 inch from 1 square mile.

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

and discharge."

"Control11 is a term used to designate a feature downstream from the gage that determines the stage-discharge relation at the gage. This feature may be a natural section, 

a reach of the channel, or an artificial structure.

"Contents" is a term applied to the volume of water in a reservoir. Unless otherwise 

indicated, it is computed on the basis of a level pool and does not include bank storage.

1
2 SURFACE WATER SUPPLY, 1950, PART 1

"Drainage area" of a stream at a specified location is that area, measured in a horizontal plane, which is enclosed by a topographic divide such that direct surface runoff 

from precipitation normally would drain by gravity into the river basin above the specified point. Figures of drainage area given herein Include all closed basins or noncontributing areas within the area unless otherwise noted.

EXPLANATION OF DATA

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

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

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

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

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

discharge. Typical structures in use at gaging stations are shown in figure 1.

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

daily mean discharge, frrom which the monthly and the yearly mean discharge are computed. 

If the stage-discharge relation is subject to change because of frequent or continual 

change in the physical features that form the control, the daily mean discharge is determined by the "shifting-control method," in which correction factors based on individual discharge measurements and notes by engineers and observers are used in applying the 

gage heights to the rating tables. At times the stage-discharge relation for a station 

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

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

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

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

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

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

the stage-discharge relation is affected by changing stage, and for them the rate of 

change of stage is used as a factor in the determination of discharge.

At most gaging stations in the northern part of the United States and at some in the 

mountainous regions of other parts the stage-discharge relation is affected by ice during 

the winter, which makes it impossible to compute the discharge in the usual manner. Discharge for periods of ice effect is computed on the basis of the gage-height record and 

occasional winter discharge measurements, consideration being given to the available information on temperature and precipitation, noteis by gage observers and engineers, and 

comparable records of discharge for stations in the same or nearby basins. For those 

stations at which the stage-discharge relation i,s affected by ice, the days included in 

the periods of ice effect either are indicated in the table by symbols referring to a 

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

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

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

by a footnote.

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

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

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

tables_ are published for all stations except those at which the daily 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, location, drainage area, records 

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

given the average discharge for the number of years indicated. It is not given for stations having less than 10 complete years of record or for stations where changes in water 

development during the period of record cause the figure to have little significance. 

Under "Extremes" are given the maximum discharge and gage height; the minimum discharge if 

there is little or no regulation; the minimum daily discharge if there is extensive regulation (also the minimum discharge if useful); and the minimum gage height (unless it is 

of no importance). Unless otherwise qualified, the maximum discharge corresponds to the 

crest stage, obtained by use of a water-stage recorder, a crest-stage indicator, or a nonrecording gage read at the time of the crest. Information pertaining to the accuracy of 

the records and conditions which affect the natural flow at the gaging station is given 

under "Remarks."

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

basis of data or Information obtained subsequently. Revisions of such records are usually 

published along with the current records In one of the annual reports. In order to make 

it easier to find such revised records, a paragraph headed "Revisions (water years)" has 

been added to the station description of all stations for which revised records have been 

published. Listed therein are all the reports in which revisions appear, each followed by 

the water years for which figures are revised in that report. In listing the report 

number, W. means Water-Supply Paper. In listing the years, water years are indicated by 

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

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

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

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

minimum was revised; and (P) that only peak discharges were revised. If the drainage area 

has been revised, the report in which the revised figure was first published is given. It 

should be noted that for all stations for which second-feet per square mile and runoff In 

inches are published, a revision of the drainage area necessitates corresponding revision 

of all figures based on the drainage area. Revised figures of second-feet per square mile 

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

published in the annual series of reports.

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

sudden or rapid fluctuation, the table gives the discharge corresponding to the daily mean 

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

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

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

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

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

equipped with nonrecording gages, the table of daily discharge gives the discharge
ACCURACY OP FIELD DATA AND COMPUTED RESULTS 5

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

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

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

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

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

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

"Maximum" gives the maximum daily discharge, not the momentary discharge when the water 

surfaee was at crest stage. Likewise, in the column headed "Minimum" the quantity given 

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

feet per second during the month.

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

discharge for most stations. All independent peaks above the selected base are given. The 

base discharge, which is given in parentheses, is selected so that an average of about 

three peaks a year will be presented. Peak discharges are not published for canals, 

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

by man.

For most gaging stations on lakes and reservoirs the data presented comprise a description of the station and a monthly summary table of stage and contents. For some reservoirs a table showing daily contents or stage is given. A skeleton table of capacity at 

given stages is usually given in the first report in which data for a station are published 

but is omitted from succeeding reports.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of stream-flow data depends primarily on (1) the permanency of the stagedischarge relation or, if the control is unstable, the frequency of discharge measurements 

and (2) the accuracy of observations of stage, measurements of flow, and interpretation of 

records.

The station description gives a statement in regard to the general accuracy of the records . "Excellent" indicates that, in general, the error in the daily records la believed 

to be less than 5 percent; "good," less than 10 percent; "fair," less than 15 percent; and 

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

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

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

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

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

square mile" and "runoff in inch.es" are not published unless storage or diversion records 

are included Indicating the extent of the regulation or diversion or unless satisfactory 

adjustments can be made for changes in contents or reservoirs or for other changes incident 

to use and control. Evaporation from a reservoir is not included in the adjustments for 

changes in reaervoir contents, unless its inclusion is indicated. Even at those stations 

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

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

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

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

the average annual rainfall over the drainage area is less than 20 inches.
6 SURFACE WATER SUPPLY, 1950, PART 1

Many gaging stations on streams in the irrigated areas of the United States are situated 

above most of the diversions from those streams, and therefore the discharge recorded does 

not show the water supply available for further development, as prior appropriations below 

the station must first be satisfied.

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

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

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

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

are subject to revision in succeeding water-supply papers.

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

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

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

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

relative order as the streams and gaging stations in the body of the report. An index of 

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

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

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

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

record have been collected. These summaries are available also as separate reprints.

Reports have been published that are compilations of records for various areas, usually 

a single State or drainage basin. These reports contain records previously published 

(some of which have been revised), as well as some records not contained in the annual 

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

reports, arranged alphabetically, some by States and some by drainage basins.

Extremes.--Maximum discharge during year, 22,100 second-feet Apr. 23 (gage height, 10.03 

1'eet}; minimum, 252 second-feet July 25 (gage height, 1.88 feet).

1930-50: Maximum discharge, 37,800 second-feet Mar. 22, 1936; maximum gage height, 

15.50 feet (present datum) Apr. 15, 1940 (backwater from ice); minimum daily discharge, 

75 second-feet Feb. 13-15, 1948.

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

wnTch are fair. Plow partly regulated by Squapan Lake (capacity, 2,554,000,000 cubic 

feet) and by Millinocket Lake (capacity, 1,007,000,000 cubic feet) used for power, and 

Machias and Rowe Lakes (combined capacity, about 280,000,000 cubic feet) used for log

Merrlmack River near Goffs Falls, below Manchester, N. H.

Location. Water-stage recorder, lat. 42°56'55", long. 71°27'45", 0.8 mile downstream from 

Bowman Brook, 1.3 miles north of Goffs Palls, Hillsboro County, and 2.3 miles downstream 

from Piscataquog River.

Drainage area. 3,092 square miles.

Kecoras available. November 1936 to September 1950.

Average aiacnargS1 . 14 years, 5,072 second-feet.

Extremes. Maximum discharge during year, 29,200 second-feet Apr. 22 (gage height, 10.42 

feetJ; minimum daily, 180 second-feet Aug. 13.

1936-50: Maximum discharge, 102,500 second-feet Sept. 23, 1938 (gage height, 25.87 

feet), from rating curve extended above 48,000 second-feet on basis of computations of 

flow over dam at gage heights 25.87 and 35.19 feet; minimum daily, 154 second-feet Sept. 

5, 1949.

Maximum discharge known, 150,000 second-feet Mar. 20, 1936 (gage height, 35.19 feet, 

from floodmarks), from rating curve extended above 48,000 second-feet by method explained above.

Remarks. Records excellent except those for periods of ice effect, which are good, and 

those for periods of no gage-height record, which are fair. Plow regulated by power 

plants and by Franklin Palls Reservoir, Squam, Little Squam, Newfound, Winnipesaukee, 

Winnisquam, Wentworth, Merrymeeting, and other lakes, and by Blackwater Reservoir. See 

pages 82, 87 for description and monthly change in contents of many of these reservoirs.

1930-50: Maximum discharge, 32,000 second-feet Sept. 21, 1938 (gage height, 16.39 

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

about 0.3 second-foot Aug. 6, 1937; minimum daily, 2.3 second-feet Sept. 11, 12, 1943.

Remarks.--Records excellent except those for periods of ice effect, backwater from leaves

 on control, or no gage-height record, which are fair. City of Willimantic diverts an 

average of about 1 million gallons of water a day for municipal supply from reservoir 

2 miles above station. Diurnal fluctuation at low flow caused by water wheels at outlet of this reservoir.

THAMES RIVER BASIN 143

Quinebaug River at Putnam, Conn.

Location (revised).--Water-stage recorder, lat. 41"54"34", long. 71°54'48", at Putnam, 

Windham County, 600 feet downstream from Little River and 3 miles downstream from 

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

Drainage area.--331 square miles.

Records "available .--December 1929 to September 1950.

Average discharge. 21 years, 534 second-feet.

Ex.trem.es. Maximum discharge during year, 1,850 second-feet Mar. 9 (gage height, 5.96

feet); minimum, 17 second-feet July 29; minimum gage height, 1.60 feet Oct. 24; minimum 

daily discharge, 29 second-feet Oct. 23.

1929-50: Maximum discharge, 20,900 second-feet Sept. 21, 1938 (gage height, 19.45 

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

Little River 2 miles upstream from its mouth; minimum, 8.5 second-feet Oct. 26, 1935; 

minimum daily, 11 second-feet Oct. 5, 12, 1930.

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

City of Putnam diverts an average of less than 1 million gallons per day from Little 

River for municipal supply. Large diurnal fluctuation, particularly during low flow, 

caused by many dams and reservoirs above station, largest of which is Lake Chaubunagungamaug with an estimated usable capacity of 207.000,000 cubic feet.

for diversions and change in reservoir contents).

Extremes. Maximum discharge during year, 2,510 second-feet Mar. 30 (gage height, 7.52 

feet); minimum daily, 58 second-feet Oct. 19.

1928-50: Maximum discharge, 45,200 second-feet Sept. 21, 1938, by computation of 

flow over dam; minimum daily, 16 second-feet several times in 1929-31.

Remarks. Records excellent except those for periods of ice effect or backwater from

aquatic vegetation, which are good. Water is diverted for Boston metropolitan district 

and since May 1950 for city of Chicopee from 186 square miles in Swift River Basin and 

at times during period Oct. 15 to June 14 from 97 square miles in Ware River Basin, and 

from Ludlow Reservoir for ase in Springfield and Chicopee. Flow regulated by power 

plants above station, and by Quabbin Reservoir on Swift River (see p. 161 ) and smaller 

reservoirs.

d Doubtful gage reading; discharge computed on basis of records for East Branch Eightmile River.
234 MENUNKETESUCK RIVER BASIN 

Menunketesuck River near Clinton, Conn.

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

aovmstream from Cobb's Bridge, 1.7 miles north of Clinton, Middlesex County, 2.4 miles 

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

Drainage area.--11.6 square miles.

Hecoras available.--June 1941 to September 1950.

Extremes (unadjusted for storage or diversion).--Maximum discharge during year, 151 secondreet June 4 [gage height, 3.17 reet, oacKwater from debris); minimum, 0.13 second-foot 

Oct. 13-25; minimum gage height, 0.74 foot Oct. 13-16.

1941-50: Maximum discharge, 870 second-feet Nov. 12, 1947 (gage height, 6.72 feet), 

from rating curve extended above 270 second-feet on basis of logarithmic plotting; no 

flow at times during August and September 1944; minimum gage height, 0.48 foot Sept. 

9-12, 1944.

Remarks.--Records excellent except those for periods of backwater from leaves and debris 

ana those below 2.5 second-feet, which are good. The daily discharge record for all 

periods except those of low flow is a summation of dally flow at gaging station and 

daily diversion from Kelseytown Reservoir as measured by venturi meter. During periods of low flow, diversions from Kelseytown Reservoir are compensated for by release 

of water from Killingworth Reservoir which is located about 2.5 miles upstream from 

Kelseytown Reservoir on a small tributary of Menunketesuck River. The drainage area 

of Killingworth Reservoir is so small that its yield is considered negligible during 

periods of low flow when It becomes necessary to draw upon it. Therefore, the daily 

discharge record for periods of low flow Oct. 1 to Nov. 2, Nov. 6-13, 22-24, July 24 

to Aug. 20, Sept. 2-30, is a summation of daily flow at gaging station and daily diversion from Kelseytown Reservoir, minus daily draft on Killingworth Reservoir adjusted 

for daily change in contents In Kelseytown Reservoir. Draft on Killingworth Reservoir 

is determined at a staff-gage station just below spillway. Change in contents in Kelseytown Reservoir is determined at a temporary recording station at dam. No account 

Is taken of evaporation from the reservoir surfaces. Flow at recording gage station 

regulated by Killingworth and Kelseytown Reservoirs and by diversion for domestic water 

supply from Kelseytown Reservoir.

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

Discharge, in second-feet, water year October 1949 to September 1950

240 HOUSATONIC RIVER BASIN

Housatonic River at Stevenson, Conn.

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

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

dam of Connecticut Light & Power Co. at Stevenson, Falrfield County. Datum of gage is 

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

Drainage area. 1,545 square miles.

Records available. August 1928 to September 1950.

Average discharge. 22 years, 2,478 second-feet (adjusted since 1936).

Extremes. Maximum discharge during year, 9,450 second-feet Mar. 9 (gage height, 9.33

 fe'et)'; minimum, 41 second-feet Oct. 23 (gage height, 0.46 foot); minimum daily, 48 

second-feet Oct. 23.

1928-50: Maximum discharge, 69,500 second-feet Mar. 12, 1936 (gage height, 23.5 

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

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

regulation.

Remarks. Records excellent. Ordinary flow completely regulated by Stevenson hydro-

 electric plant. Plow regulated by Candlewood Lake, Lake Zoar, and Shepaug Reservoirs 

having a combined usable capacity of 6,600,000,000 cubic feet (see p. 241), and by 

small diversion from basin at Shepaug Reservoir.

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

times.

Remarks. Records good except those for periods of rapidly changing stage or no gageFTelght record, which are fair. Discharge computed on basis of flow over spillway,

. -through floodgates, and through fountain at" toe of dam. Rating curves for floodgates 

and fountain computed by means of a temporary sharp-crested weir below dam. Rating 

curve for spillway computed for discharges below 18.5 second-feet by means of same 

weir and for discharges above 18.5 second-feet .by a formula selected to fit spillwaycrest sections. Gages at dam usually read once daily. Water diverted from Shepaug 

Reservoir for municipal supply of Waterbury. Flow regulated since September 1933 by 

Shepaug Reservoir (see p. 241).

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

12.40 feet), from rating curve extended above 9,000 second-feet by logarithmic plotting 

on basis of slope-area determinations at gage height 7.56 feet and 12.4 feet; minimum, 

24 second-feet Oct. 81, 1935; minimum gage height, 0.14 foot July 17, 1939; minimum 

daily discharge, 40 second-feet Oct. 5, 12, 1930, Sept. 7, 1936.

Flood of November 1927 reached a stage of 14 feet (discharge, about 26,000 secondfeet, revised).

Remarks.--Records good. Flow regulated by plants above station during low stages and 

Dy Morris, Wigwam, and Pitch Reservoirs, having a combined capacity of 550,000,000 

cubic feet (see p. 241). Flow increased by diversion from Shepaug Reservoir into 

Naugatuck River Basin.

Note. Backwater from trees on control Nov. 14 to Mar. 15, Mar. 23 to Apr. 6, Apr. 20; discharge 

computed on basis of 4 discharge measurements, engineers' notes, weather records, and records for 

Naugatuck River near Thomaston and Burlington Brook near Burlington.
SAUGATUCK RIVER BASIN 

Saugatuck River near Westport, Conn.

271

Location.--Water-stage recorder, lat. 41°10'15", long. 73°22'00", on old Ford Road (Clinton Avenue), 400 feet downstream from West Branch, 600 feet downstream from dam of 

Dorr Co., and 2 miles north of Westport, Pairfield County.

Drainage area.--77.5 square miles.

Records available.--September 1932 to September 1950.

Average discharge. 18 years, 138 second-feet (adjusted for storage and diversion from 

Saugatuek Reservoir since October 1941).

Extremes.--Maximum discharge during year, 441 second-feet June 2 (gage height, 4.33 feet); 

minimum, 0.4 second-foot Oct. 18 (gage height, 1.97 feet); minimum daily discharge, 

4.1 second-feet Oct. 18.

1932-50: Maximum discharge, 5,310 second-feet Mar. 12, 1936 (gage height, 11.30 

feet), from rating curve extended above 1,700 second-feet, verified by computation of 

flow over dam for flood of September 1938 (gage height, 10.28 feet); minimum, 0.3 

second-foot Aug. 13, 1935; minimum gage height, that of Oct. 18, 1950; minimum daily 

discharge, 1.0 second-foot Aug. 11, 1939.

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

Flow regulated by storage and diversion at Saugatuck Reservoir (total capacity, 

11,900,000,000 gallons) and Aspetuck Reservoir. At Aspetuck Reservoir, Bridgeport 

Hydraulic Co. diverts an indeterminable amount of water for domestic supply from about 

17 square miles of Saugatuck River Basin through Hemlocks Reservoir in Mill River Basin.

sea level, datum of 1929.

Drainage area.--9.20 square miles.

Records available. November 1943 to September 1950.

Extremes.--Maximum discharge during year, 119 second-feet Mar. 2? (gage height, 2.40 feet);

 minimum, 0.56 second-foot Oct. 23 (gage height, 0.90 foot).

1943-50: Maximum discharge, 1,330 second-feet Sept. 15, 1944 (gage height, 9.36 

feet), from rating curve extended above 800 second-feet by logarithmic plotting; minimum, 0.20 second-foot Aug. 16, 1944 (gage height, 0.84 foot).

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

 BaBcwater from debris, which are good, and those for periods of no gage-height record, 

which are fair. Medium flow affected slightly by detention reservoir 2 miles above station (capacity, about 26 acre-feet at spillway level or 50 acre-feet at crest of concrete dam).

STREAMS ON LONG ISLAND 27£

Nissequogue River near Smithtown, N. Y.

Location. Water-stage recorder and concrete control, lat. 40°50'55", long. 73°13'25",

'hair a mile downstream from Blydenburg Pond and 1 mile southwest of Smithtown, Suffolk 

County. Datum of gage is 9.59 feet above mean sea level, datum of 1929.

Drainage area. About 27 square miles.

'Records available. October 1943 to September 1950.

'Extremes. Maximum discharge during.year, 99.9 second-feet Aug. 20 (gage height, 1.044 

reet); minimum, 28.7 second-feet Feb. 21 (gage height, 0.582 foot); minimum daily, 29 

second-feet Aug. 2.

1943-50: Maximum discharge, 147 second-feet Sept. 14, 1944 (gage height, 1.32 feet, 

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

second-feet on basis of logarithmic plotting; minimum, 19.2 second-feet Oct. 6, 1947 

(gage height, 0.469 foot); minimum daily, 20.0 second-feet Oct. 6, 1947.

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

or fragmentary gage-height record, which are good, and those for period of no gageheight record, which are fair. Flow partly regulated by cleaning of fish screens and 

trash racks at outlets of Blydenburgh Pond on main stream and ponds on tributaries 

entering stream above station. This station is operated in connection with an inventory of ground-water resources on Long Island. In addition to records of stream flow, 

records of ground-water levels are collected, some of which are published in watersupply papers.

6.54 feet above mean sea level, adjustment of 1912.

Drainage area. About 75 square miles.

Records available. June 1942 to September 1950.

Extremes. Maximum discharge during year, 67.3 second-feet Feb. 15 (gage height, 0.689 

foot); minimum, 2.82 second-feet Feb. 21 (gage height, 0.154 foot); minimum daily, 

10.2 second-feet Aug. 15.

1942-50: Maximum discharge, 86.9 second-feet Aug. 20, 1942 (gage height, 0.769 

foot); minimum, 1.80 second-feet Jan. 22, 1947 (gage height, 0.120 foot); minimum 

daily, 3.67 second-feet Aug. 2, 1944.

Remarks.--Records excellent except those for periods of no gage-height record or backwater from aquatic vegetation or debris, which are good. Flow regulated by operation 

of gates in dam just above station. This station is operated in connection with an 

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

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

water-supply papers.

1947 (gage height, 0.050 foot); minimum daily, 6.29 second-feet Aug. 3, 1941/.

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

or debris and for period of obstruction in channel, which are good. Flow regulated 

infrequently at outlet of Swan Lake. This station is operated in connection with an 

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

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

water-supply papers.

Location.--Water-stage recorder, lat. 40°45'55", long. 73°01'15", just downstream from 

Montauk highway in Patchogue, Suffolk County, and 1 mile upstream from mouth. Datura of 

gage is 0.50 foot above mean sea level, datum of 1929. Auxiliary water-stage recorder 

254 feet downstream at same datum.

Drainage area. About 13.5 square miles.

Records available. October 1945 to September 1950.

Extremes. Maximum daily discharge during year, 60.0 second-feet Sept. 11; minimum daily, 

4.0 second-feet May 9.

1945-50: Maximum daily discharge, that of Sept. -11, 1950; minimum daily, that of 

May 9, 1950.

Remarks.--Records good except those for periods of doubtful gage-height record at base 

gage or no gage-height record at base or auxiliary gage, which are fair. Discharge 

computed by using fall as a factor. Occasional diurnal regulation by power plant above 

station. This station is operated in connection with an inventory of ground-water 

resources on Long Island. In addition to records of stream flow, records of groundwater levels are collected, some of which are published in water-supply papers.

upstream side of John Street Bridge in Babylon, Suffolk County, 180 feet downstream 

from Long Island Railroad and 3,000 feet upstream from mouth. Datum of gage is 6.70 

feet above mean sea level, datum of 1929.

Drainage area.--About 23 square miles.

Records available.--October 1944 to September 1950.

Extremes. Maximum discharge during year, 20.9 second-feet Feb. 15 {gage height, 0.669 

rootJ; minimum, 3.55 second-feet July 31 (gage height, 0.281 foot); minimum daily, 4.1 

second-feet Oct. 25.

1944-50: Maximum discharge, 49.9 second-feet July 13, 1948 (gage height, 1.009 feet), 

from rating curve extended above 30 second-feet by logarithmic plotting; minimum, 3.26 

second-feet Oct. 5, 1945; minimum gage height, 0.279 foot Oct. 24, 1947; minimum daily 

discharge, 3.45 second-feet Oct. 5, 1945.

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

or debris, which are good. Slight intermittent regulation by automatic pumping station 

at railroad upstream and occasional regulation from changing stop logs in fish ponds 

upstream. This station is operated in connection with an inventory of ground-water 

resources on Long Island. In addition to records of stream flow, records of gouundwater levels are collected, some of which are published in water-supply papers.

Santapogue River at Lindenhurst, N. Y.

Location.--Water-stage recorder and concrete control, lat. 40°41'31", long. 73°21'20", on 

East Hoffman Avenue, 1 mile east of Long Island Railroad station In Lindenhurst, Suffolk 

County, and ij miles upstream from mouth. Datum of gage Is 9.71 feet above mean sea 

level, datum of 1929.

Drainage area.--About 7 square miles.

Records available.--June 1947 to September 1950.

Extremes.--Maximum discharge during year, 13.7 second-feet Aug. 20 (gage height, 0.626 

root); minimum, 1.42 second-feet Oct. 24, 25 (gage height, 0.234 foot, backwater from 

aquatic vegetation).

1947-50: Maximum discharge, 22.6 second-feet July 14, 1948 (gage height, 1.152 

feet); minimum, 0.97 second-foot Aug. 11, 1949 (gage height, 0.192 foot).

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

or no gage-height record, which are good. This station is operated in connection with 

an inventory of ground-water resources en Long Island. In addition to records of stream 

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

water-supply papers.

292 STREAMS ON LONG ISLAND

East Meadow Brook at Freeport, N. Y.

Location. Water-stage recorder and concrete control, lat. 40°39 I 55", long. 73°34'10", in 

Freeport, Nassau County, 50 feet upstream from bridge on Hempstead-Babylon turnpike, and 

300 feet west of East Meadow Brook Parkway. Datum of gage is 10.92 feet above mean sea 

level, adjustment of 1912.

Drainage area.--About 31 square miles.

Hecprds available. October 1851 to December 1852, June to October 1883, September and October i«8b, June to October 1903 (fragmentary, in Professional Paper 44), January 1937 

to September 1950.

Average discharge.--13 years (1937-50), 16.76 second-feet.

extremes. Maximum discharge during year, 170 second-feet Aug. 20 (gage height, 1.604 feet, 

Daclcwater from Freeport Pond); minimum, 7.77 second-feet July 30 (gage height, 0.337 

foot).

1903, 1937-50: Maximum discharge, 297 second-feet Feb. 15, 1944; maximum gage 

height, 3.15 feet Feb. 8, 1941 (backwater from Freeport Pond), from floodmark in gage 

house; minimum discharge, 5.04 second-feet (caused by ice jam above station) Feb. 21, 

1942 (gage height, 0.283 foot).

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

2, 1885.

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

backwater from aquatic vegetation or debris, which are good, and those for periods of no 

gage-height record or backwater from Freeport Pond, which are fair. This station is operated in connection with an inventory of ground-water resources on Long Island. In 

addition to records of stream flow, records of ground-water levels are collected, some 

of which are published in water-supply papers.

maximum gage neignt, 22.19 feet Mar. 29; minimum daily discharge, 2,620 second-feet 

Aug. 27; minimum gage height, 14.15 feet Aug. 28.

1946-50: Maximum discharge, 181,000 second-feet Dec. 31, 1948 (gage height, 27.05 

feet, from high-water mark in gage well); maximum daily, 141,000 second-feet Dec. 31, 

1948, Jan. 1, 1949; minimum daily, 1,270 second-feet Sept. 5, 1949; minimum gage height, 

13.92 feet Sept. 2, 1946.

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

information by Corps of Engineers (discharge, 215,000 second-feet). Flood of Mar. 28, 

1913, prior to construction of Sacandaga Reservoir and Troy lock and Dam, reached a 

stage about 0.2 foot higher upstream from former dam near same site. Downstream from 

dams, flood of 1913 was about 3.3 feet higher than flood of 1936, from information by 

Corps of Engineers.

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

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

\z miles downstream, Is shown separately. Flow appreciably regulated by Sacandaga Reservoir (see p. 306), Indian Lake Reservoir (see p. 302), and Delta, Hinckley, and 

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

for New York City (see records for Mohawk River at Cohoes and Schoharie Creek at 

Burtonsville). During canal navigation season, water is received from Black River 

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

Chenango River Basin through Oriskany Creek feeder. Water is diverted into (or may 

occasionally be received from) Cswego River Basin through summit level of Barge Canal 

between New London and Utiea.

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

Power Commission project.

310 HUDSON RIVER BASIN

Glens Falls feeder at Dunham Basin, N. Y.

Location. Water-stage recorder, lat. 430 18'15", long.73°52'50", at Dunham Basin, Washington County, 100 feet upstream from Bond Brook, and 8 miles downstream from feeder dam 

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

Records available. September 1945 to September 1950 (navigation seasons only).

Remarks. Records excellent except those for periods of backwater from debris or no gageheight record, which are good. Flow regulated in accordance with requirements of 

Champlain Canal. Operation of feeder discontinued Dec. 2 and resumed Apr. 12; discharge 

record began Apr. 15. Discharge shown during intervening period consists of leakage 

through head gates and runoff from area tributary to feeder above station. This flow 

may continue during period of no record.

322 HUDSON RIVER BASIN

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

Location. Water-stage recorder, lat. 43 0 15'50", long. 75°26'10", at Spring Brook fish

 hatchary, 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. 

Hecords available.--October 1927 to September 1950 in reports of Geological Survey. De-

 cember 1919 to September 1926 (prior to July 1921, gage heights only) in reports of

State engineer and surveyor.

Average discharge.--29 years (1921-50), 402 second-feet (unadjusted). 

Extremes.--Maximum discharge during year, 1,920 second-feet Apr. 4 (gage height, 5.41

 feet); minimum, 104 second-feet Sept. 27 (gage height, 1.31 feet); minimum daily, 157 

second-feet Apr. 30.

1927-50: Maximum discharge, 8,560 second-feet Oct. 2, 1945 (gage height, 11.18 

feet); minimum, 30 second-feet Sept. 27, 1945 (gage height, 0.65 foot); minimum daily, 

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

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

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

Reservoir above station. Flow almost completely regulated by Delta Reservoir (capacity, 2,800,000,000 cubic feet). Small quantity of water diverted from Delta Reservoir 

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

Revisions.--W 851: Drainage area.

Note. Elevation of water surface of Delta Reservoir 539.35 feet at 12 p.m. Sept. 30, 1949; 538.3 

feet at 12 p.m. Sept. 30, 1950s 546.05 feet at 12 p.m. Dec. 31, 1948; 546.65 feet at 12 p.m. Dec. 31,

HUDSON RIVER BASIN 323

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 4| miles southeast of 

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

level (Barge Canal datum).

Drainage area.--1,348 square miles.

Records available. February to April 1901, October 1927 to September 1950. November 

19X3 to September 1927 in files of State Department of Public Works.

Average discharge.--23 years (1927-50), 2,803 second-feet.

Extremes. Maximum discharge during year (river channel only), 21,200 second-feet Mar. 29 

(gage height, 16.22 feet); minimum (river channel only), 427 second-feet July 31 (gage 

height, 4.38 feet); minimum daily (including canal), 580 second-feet July 31.

1927-50: Maximum discharge (river channel only), 25,300 second-feet Oct. 3, 1945 

(gage height, 17.80 feet); minimum (river channel only), 214 second-feet Aug. 18, 1949 

(gage height, 3.75 feet); minimum daily (including canal), probably not less than 463 

second-feet Sept. 2, 1934.

Remarks. Records excellent except those for periods of ice effect, which are good. Records of daily discharge include diversion at Rocky Rift Dam into Barge Canal for power 

and lockage at lock 16, near St. Johnsville. During canal navigation season, water is 

 received from Black River Basin through Black River Canal (flowing south) and Lansing 

Kill, and possibly from Chenango River Basin through Oriskany Creek feeder. Water is 

diverted into (or may occasionally be received from) Oswego River Basin through summit 

level of Barge Canal between New London and Utica. Diurnal fluctuation caused by power 

plants and locks and dams on Barge Canal. Flow partly regulated by Delta and Hinckley 

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

Revisions (water years).--W 741: 1929(M), drainage area.

324 HUDSON RIVER BASIN

Mohawk River at Cohoes, N. Y.

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

Niagara Mohawk Power Corp. in Cohoes. Albany County. 6-| miles downstream from Delphus 

Kill.

Drainage area. 3,456 square miles.

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

plant or wew iork Power & Light Corp.) and October 1925 to September 1950. December 

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

at Crescent Dam).

Average discharge.--32 years (1918-50), 5,697 second-feet.

Extremes.--Maximum discharge during year, 72,800 second-feet Mar. 29 (gage height, 19.14 

reet); minimum, 140 second-feet Feb. 22 (gage height, 4.81 feet); minimum daily, 502 

second-feet Aug. 27.

1925-50: Maximum discharge, 130,000 second-feet Mar. 19, 1936 (gage height, 22.57 

feet), from rating curve extended above 34,500 second-feet by logarithmic plotting; minimum, 6 second-feet Sept. 28, 1941 (gage height, 3.40 feet); minimum daily, 23 secondfeet Aug. 24, 1941.

Remarks. Records excellent. Records include small diversion Just above gage for Cahoes 

water supply but do not include diversion through lock 6 at Crescent Dam (published herewith) for operation of Barge Canal. During canal navigation season, water is received 

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

possibly from Chenango River Basin through Oriskany Creek feeder. Water is diverted 

into (or may occasionally be received from) Oswego River Basin through summit level o£ 

Barge Canal between New London and Utica. Most of flow of Schoharie Creek above Oilboa 

Dam, a tributary of Mohawk River, is diverted out of basin through Shandaken tunnel for 

New York City water supply. Plow partly regulated by storage, principally in Delta, 

Hinckley, and Schoharie Reservoirs (combined capacity, 8,738,000,000 cubic feet). Extensive diurnal fluctuation caused by School Street power plant.

366 PASSAIC RIVER BASIN

Wanaque River at Wanaque, N. J.

Location.--Water-stage recorder and concrete control, lat. 41°02'33", long. 74°17'36", 

Just downstream from Wanaque Reservoir in Wanaque, Passaic County, and 50 feet upstream from highway bridge. Datum of gage is 210.00 feet above mean sea level (New 

Jersey Geological Survey bench mark).

Drainage area. 90.4 square miles (considered as 94 square miles Oct. 1, 1928, to Sept. 

3U, 1934, when flow diverted from Post Brook was included in all records).

Records available.--December 1903 to December 1905 (gage heights only), May 1912 to May 

I9lfa, May 1919 to September 1950.

Average discharge.--31 years (1919-50), 160 second-feet (adjusted for storage and diversion since October 1929).

Extremes. Maximum discharge during year, 37 second-feet June 27, Aug. 29 (gage height, 

1.57 feet); minimum daily, 0.5 second-foot Dec. 11, 12, 14-23.

1912-15, 1919-50: Maximum discharge, 5,050 second-feet Apr. 7, 1924 (gage height, 

8.01 feet, site then in use); minimum daily, that of Dec. 11, 12, 14-23, 1949.

Remarks. Records excellent. Water diverted from Post Brook into Wanaque Reservoir is 

included in records of daily discharge and observed monthly discharge. Records of 

diversion from Post Brook obtained by use of water-stage recorder and concrete control. 

Flow regulated by Greenwood Lake (see p. 363), 11 miles above station, and since 1928 

by Wanaque Reservoir (capacity, 3,476,000,000 cubic feet) from which water is diverted 

for municipal supply.

Cooperation. Water-stage recorder graphs and records of diversion from and change in con-

 tents in Wanaque Reservoir furnished by North Jersey District Water Supply Commission.

DELAWARE RIVER BASIN 411

Delaware River at Port Jervis, N. Y.

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

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

415.35 feet above mean sea level, datum of 1929.

Drainage area.--3,076 square miles.

Kecords available.--October 1904 to September 1950.

Average discharge.--46 years, 5,532 second-feet.

Extremes. Maximum discharge during year, 62,000 second-feet Apr. 5 (gage height, 11.74 

FeetT; minimum, 567 second-feet Oct. 25 (gage height, 1.31 feet); minimum daily, 625 

second-feet Oct. 23.

1904-50: Maximum discharge, 140,000 second-feet May 23, 1942 (gage height, 17.76 

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

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

second-feet Sept. 23, 1908.

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

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

by logarithmic plotting and velocity-area studies; maximum stage known, 25.5 feet Mar. 

8, 1904 (ice jam).

Remarks.--Records excellent except those for periods of ice effect or fragmentary gageheight record, which are good. Large diurnal fluctuations at medium and low flow caused 

by power plants on tributary streams. Plow regulated by Lake Wallenpaupack and by 

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

cubic feet).

Cooperation. Records of storage furnished by Pannsylvania Power & Light Co. for Lake 

Wallenpaupack and by Rockland Light & Power Co. for Toronto, Cliff Lake, and Swingl 

Bridge Reservoirs.

Kecprds available. March 1936 to February 1940 (gage heights only), February 1940 to

September 1950.

Average discharge.--10 years, 6,402 second-feet (adjusted).

Extremes. Maximum discharge during year, 65,500 second-feet Apr. 5 (gage height, 17.81 

TeeTT; minimum, 660 second-feet Oct. 25 (gage height, 4.15 feet); minimum daily, 726 

second-feet Oct. 24.

1940-50: Maximum discharge, 136,500 second-feet May 23, 1942 (gage height, 25.70 

feet), from rating curve extended above 90,000 second-feet; minimum, 385 second-feet 

Aug. 28, 29, 1949 (gage height, 3.76 feet); minimum daily, 428 second-feet Sept. 27, 

1943,

Maximum stage known, 35.5 feet (present datum) Oct. 10, 1903, from floodmark. 

Gage height of 28.45 feet (present datum) was observed Mar. 18, 1936 (discharge, 

164,500 second-feet, from present rating curve extended above 90,000 second-feet). 

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

which are fair. Diurnal fluctuation at medium and low flow caused by power plants on 

tributary streams. Flow regulated by Lake Wallenpaupack and by Toronto, Cliff Lake, 

and Swinging Bridge Reservoirs (combined capacity, 12,300,000,000 cubic feet).

from rating curve extended above 480 second-feet by logarithmic plotting; minimum, 3.9 

second-feet Sept. 29 (gage height, 1.52 feet).

1924-50: Maximum discharge observed, 2,500 second-feet Aug. 26, 1928 (gage height, 

8.7 feet, from floodmarks), from rating curve extended above 470 second-feet by logarithmic plotting on basis of slope-area determination at gage height 8.5 feet; minimum, 1.0 second-foot Aug. 1, 3, 5, 1936 (gage height, 1.23 feet).

Remarks.--Records excellent except those for periods of ice effect, backwater from debris, 

or no gage-height record, which are good. Small diversion from Lily Pond for Liberty 

water supply. Subsequent to May 15, 1950, low flows slightly affected by highway 

construction above station.

DELAWARE RIVER BASIN 431

Cold Spring Brook at China, Nu Y.

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

long. 75°23'35", 1 mile upstream from China, Delaware County, and 3 miles east of 

North Sanford. Datum of gage is ],490.76 feet above mean sea level, adjustment of 1912 

(levels by Corps of Engineers).

Drainage area. 1. 51 square miles.

Records available. October 1934 to September 1950.

Average discharge. --15 years (1935-50), 2.67 second-feet.

Extremes . Maximum discharge during year, 73.2 second-feet Apr. 4 (gage height, 3.34 feet), 

rrom rating curve extended above 17 second-feet on basis of logarithmic plotting; minimum, 0.118 second-foot Sept. 30 (gage height, 1.28 feet).

1934-50: Maximum discharge, 335 second-feet Oct. 30, 1935 (gage height, 4.5 feet, 

from f loodmarks ) , from rating curve extended above 55 second-feet on basis of theoretical rating; minimum, 0.007 second-foot Aug. 13, 1944; minimum gage height, 1.075 feet 

Aug. 3, 1936.

Remarks . Records excellent except those for periods of ice effect or backwater from deoris, which are good, and those for periods of fragmentary or no gage-height record, 

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

reforestation on stream flow. In addition to records of stream flow, records of rainfall, temperature, and ground-water levels are collected. Weekly records of groundwater elevations for 1950 are published in Water-Supply Paper 1165.

530 SUSQUEHANNA RIVER BASIN

Sage Brook near South New Berlin, N. Y.

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

 long. 75 0 25'30", l| miles upstream from mouth and 2| miles west of South New Berlin, 

Chenango County. Datum of gage is 1,430.17 feet above mean sea level, adjustment of 

1912 (levels by New York State Department of Conservation).

Drainage area. 0.70 square mile.

Records available.--November 1932 to September 1950.

Average discharge.--17 years (1933-50), 1.08 second-feet.

Extremes.--Maximum discharge during year, 35.4 second-feet Sept. 1 (gage height, 3.36

 feet); minimum, 0.050 second-f-oot Aug. 27 (gage height, 1.19 feet).

1932-50: Maximum discharge, 287 second-feet July 22, 1945 (gage height, 5.53 feet), 

from computation of flow over dam; minimum, 0.0002 second-foot Sept. 19, 20, 1939.

Remarks.--Records good except those for periods of ice effect, faulty intake action, shift-

 ing control, or no gage-height record, which are fair. This station is operated in connection with a study of the effect of reforestation on stream flow. In addition to records of stream flow, records of precipitation, temperature, and ground-water levels are 

collected. Weekly records of ground-water levels for 1950 are published in Water-Supply 

Paper 1165.

Revisions (water years).--W 871: Drainage area. W 1081: 1934-44.

feet), from rating curve extended above 1,500 second-feet by logarithmic plotting; minimum, 7.3 second-feet Aug. 15 (gage height, 2.24 feet); minimum daily, 10 second-feet 

Aug. 15.

1938-50: Maximum discharge. 5,890 second-feet Dec. 30, 1942 (gage height, 10.4 feet, 

from floodmark on outside gage), from rating curve extended above 2,800 second-feet by 

logarithmic plotting; minimum, 0.48 second-foot (discharge measurement) Sept. 19, 1939 

(gage height, 1.73 feet); minimum daily, 0.5 second-foot Sept. 2-6, 16-20, 1939.

Remarks. Records excellent except those for periods of ice effect and those above 1,500 

second-feet, which are good. Dirunal fluctuation at low and medium flow caused by 

gristmill 800 feet above station.

SUSQTJEHMKA RIVER BASIN 539

Shackham Brook near Truxton, N. Y.

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

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

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

gage is 1,881.52 feet above mean sea level, adjustment of 1912 (levels by Corps of Engineers) .

Drainage area. 3.12 square miles.

Kecorda available. November 1932 to September 1950.

Average alscnarge. 17 years (1933-50), 6.02 second-feet.

Extremes. Maximum discharge during year, 274 second-feet Apr. 4 (gage height, 3,89 feet); 

minimum, 0.121 second-foot Aug. 17, 18 (gage height, 1.31 feet).

1932-50: Maximum discharge, 487 second-feet June 3, 1947, from rating curve extended 

above 170 second-feet by logarithmic plotting; maximum gage height, 4.45 feet June 24, 

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

Remarks.--Records good except those for periods of ice effect, shifting control, fragmentary 

or no gage-height record, or backwater from stones, which are fair. This station is 

operated in connection with a study of the effect of reforestation on stream flow. In 

addition to records of stream flow, records of precipitation, temperature, barometric 

pressure, soil temperature, evaporation, and ground-water levels are collected. Weekly 

records of ground-water levels for 1950 are published In Water-Supply Paper 1165.

Albright Creek at East Homer, N. Y.

Location. Water-stage recorder and concrete control, lat. 42°40'10", long. 76°06'15", a 

quarter of a mile upstream from highway bridge in East Homer, Cortland County, and half 

a mile upstream from mouth.

Drainage area.--7.08 square miles.

Records available. October 1938 to September 1950. Prior to October 1947, published as 

East Homer Ureek at East Homer.

Average discharge.--11 years (1939-50), 12.9 second-feet.

actremes. Maximum discharge during year, 507 second-feet Apr. 4 (gage height, 3.37 feet); 

minimum, 0.26 second-foot Aug. 17, 18 (gage height, 0.68 foot).

1938-50: Maximum discharge, 787 second-feet June 3, 1947, from rating curve extended 

above 220 second-feet by logarithmic plotting; maximum gage height, 3.80 feet Dec. 30, 

1942, from graph based on outside-gage reading; minimum discharge, 0.085 second-foot 

Sept. 2, 3, 19, 20, 1939 (gage height, 0.595 foot).

Remarks. Records good except those for periods of ice effect, which are fair. This station 

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

In addition to records of stream flow, records of precipitation, temperature, and groundwater levels are collected. Weekly records of ground-water levels for 1950 are published in Water-Supply Paper 1165.

Chemung Rivsr at Chemung, N. Y.

Location. Water-stage recorder, lat. 42°00'10", long. 76°38 I 00", just downstream from

* highway bridge, three-quarters of a mile southwest of Chemung, Chemung County, and 

10 miles upstream from mouth. Datum of gage is 778.63 feet above mean sea level, adjustment of 1912 (levels by Corps of Engineers).

Drainage area. 2,530 square miles.

Records available. September 1903 to September 1950.

Average discharge'.--44 years (1905-13, 1914-50), 2,470 second-feet.

Extremes. Maximum discharge during year, 80,300 second-feet Mar. 29 (gage height, 19.12

 i'eet); minimum, 150 second-feet Oct. 16; minimum gage height, 2.40 feet Oct. 28, 29, 30.

1903-50: Maximum discharge, 132,000 second-feet May 28, 1946 (gage height, 23.97 

feet), from rating curve extended above 65,000 second-feet on basis of slops-area and 

velocity-area determinations at gage height 19.57 feet and slope-area and contractedopening determinations at gage height 23.97 feet; minimum, 49 second-feet Aug. 14, 1911 

(gage height, 1.47 feet).

Remarks. Records excellent except those for periods of ice effect, twice-daily tape-gage 

readings, or backwater from weeds, which are good.

Revisions (water years). W 696: Drainage area. W 891: 1935-39.

550 SUSQUEHANNA RIVER BASIN

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

Location. Water-stage recorder and concrete control, lat. 42°18'50", long. 77 0 39'05", 150 

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

from Crosby Creek, and 1.5 miles downstream from Canacadea Creek. Datum of gage is 

1,131.10 feet above mean sea level (Corps of Engineers bench mark).

Drainage area. 159 square miles.

Records available. August 1942 to September 1950.

Extremes. Maximum discharge during year, 5,650 second-feet Mar. 28 (gage height, 10.46 

feet); minimum daily, 18 second-feet Oct. 15-30.

1942-50: Maximum discharge, 9,340 second-feet May 26, 1943 (gage height, 13.30 

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

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

Remarks. Records good except those for periods of partly obstructed Intake, shifting 

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

(about 2 second-feet) just above control by Erie Railroad Co. An unknown but relatively small amount of water diverted is returned to stream above control. City of Hornell 

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

a tributary above station; sewage enters river below gage. Since November 1939, flood 

flows regulated by Arkport Reservoir.

Discharge, in second-feet, water year October 1949 to September 1950

620 SUSQUEHANNA RIVER BASIN

Deer Creek at Rocks,Md.

Location.--Water-stage recorder and concrete control, lat. 39°37'49", long. 76°24'13", a 

quarter of a mile downstream from Maryland & Pennsylvania Railroad bridge, threequarters of a mile southeast of Rocks, J'arford County, 1.2 miles upstream from 

Stirrup Run, and 7 miles northwest of Belair. Datum of gage is 250.40 feet above mean 

sea level (city of Baltimore bench mark).

Drainage area.--94.4 square miles.

Records available.--October 1926 to September 1950.

Average discharge.--24 years, 121 second-feet.

Extremes.--Maximum discharge during year, 3,730 second-feet Aug. 31 (gage height, 9 48 

TeeTT; minimum, 24 second-feet Oct. 19, 20, Nov. 16 (gage height, 1.89 feet); minimum daily, 36 second-feet Aug. 1.

1926-50: Maximum discharge uncertain, occurred Aug. 23, 1933 (gage height, 17.7 

feet, from floodmarks); minimum, 8 second-feet Dec. 16, 1930, Jan. 26, 1939; minimum 

daily, 13 second-feet Aug. 2, 1931.

Revisions. The maximum discharge for the water year 1933 as published in WaterSuppiy raper 741 is believed to be too high and should not be used.

Remarks. Records excellent except those for periods of ice effect or no gage-height record, which are fair. Some regulation at low flow by mills above station.

Westernport.

Average discharge. 21 years, 74.3 second-feet.

Extremes. Maximum discharge during year, 748 second-feet Sept. 21 (gage height, 5.56

 t'eet); minimum, 5.4 second-feet Aug. 18, 29, 30.

1905-6, 1929-50: Maximum discharge, 8,500 second-feet Mar. 17, 1936 (gage height, 

9.6 feet, site then in use), by slope-area method; minimum, 1.6 second-feet Oct. 2, 

4-8, 1930.

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

which are fair. Records include about half a second-foot of sewage from city of 

Frostburg, which obtains its water supply from Big Piney Run (Monongahela River Basin) 

and Savage River. A negligible discharge diverted above station by Frostburg Water 

Co. for municipal supplies of cities of Eckhart and Welsh Hill. Records include drainage from numerous active and abandoned coal mines.

POTOMAC RIVER BASIN 669

Big Spring at Masonville, W. Va.

Location. Water-stage recorder, lat. 38°54'55", long. 79 0 04'50", on Spring Run, half a 

mile southeast of Masonville, Grant County, and 6 miles southeast of Petersburg. Altitude of gage, 1,580 feet (from topographic map).

Records available. August 1945 to September 1950.

Extremes.--Maximum discharge during year, 109 second-feet Sept. 13 (gage height, 1.86

feet); minimum, 7.3 second-feet Aug. 11-22, 25; minimum gage height, 0.31 foot Nov. 28.

1945-50: Maximum discharge, 600 second-feet June 18, 1949 (gage height, 2.68 feet) 

from rating curve extended above 100 second-feet by logarithmic plotting; minimum, 4.9 

second-feet Oct. 6-8, 1947.

Remarks.--Records good below 40 second-feet and fair above except those for periods of no 

gage-height record or indefinite stage-discharge relation which are fair below 40 

second-feet and poor above. Big Spring, which emerges at several places from 50 to 300 

feet above gage, is the source of entire flow except during wet weather when surface 

drainage from about half a square mile enters the stream above gage. Plow from surface 

source Is included in the records but is relatively small except during heavy rains.
