SCOPE OF WORK

This volume is one of a series of 18 reports presenting measurements of stage, discharge, and content of streams, lakes, and reservoirs in the United States during the water 

year ending September 30, 1952. Since 1888, when the United States Geological Survey first 

studied streamflow in relation to problems of irrigation, similar measurements have been 

made at more than 12,600 gaging stations in the 48 States and at many others in the Territories of Alaska and Hawaii. On September 30, 1952, the Geological Survey and cooperating 

organizations were maintaining 6,700 gaging stations, including those in Alaska and Hawaii. 

Miscellaneous discharge measurements were made at many other points in the 1952 water year.

Information of a more detailed nature than that published for most of the gaging stations given in this report is on file in the district offices listed above. Provisional 

records of discharge prior to publication, and other unpublished data concerning the 

gaging-station records may usually be obtained from the district office.

DEFINITION OF TERMS AND ABBREVIATIONS

The terms of streamflow and other hydrologic data, as used in this report, are defined 

as follows:

Cubic foot per second (cfs) 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.

Cubic f&et per second per square mile (cfsm) is the average number of cubic feet of 

water flowing per second from each square mile of area drained, assuming that the runoff 

is distributed uniformly in 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. The term Is used 

for comparing runoff with rainfall, which Is also usually expressed In inches.

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 relation to storage 

for irrigation.

Cfs-day is the volume of water represented by a flow of 1 cubic foot per second 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 the relation between gage height and the amount of water 

flowing in a channel, expressed as volume per unit of time.

Control designates a feature downstream from the gage that determines the stage-discharge relation at the gage. This feature may be a natural constriction of the channel, 

a long reach of the channel, or an artificial structure.

Contents is the volume of water in a reservoir. Unless otherwise indicated, volume is 

computed on the basis of a level pool and does not include bank storage.

The drainage area of a stream at a specified location is that area, measured In a horizontal plane, which Is so enclosed by a topographic divide that direct surface runoff from 

precipitation normally would drain by gravity into the river above the specified point. 

Figures of drainage area given herein include all closed basins, or noncontributing areas, 

within the area unless otherwise noted.
4 SURFACE WATER SUPPLY, 1952, PART 1-B

DOWNSTREAM ORDER OR LISTING GAGING STATIONS

Beginning with the series of reports for the water year ending September 30, 1951, the 

order of listing gaging-station records was changed. In this report, in a downstream direction along the main stem all stations on a tributary entering above a main-stem station 

are listed before that station. If a tributary enters between the two main-stem stations, 

it is listed between them. A similar order is followed in listing stations on first rank, 

second rank, and other ranks of tributaries. To indicate the rank of any tributary on 

which a gaging station is situated and the-stream to which it is immediately tributary, 

each indention in the listing of gaging stations in the table of contents of this report 

represents one rank. This downstream order and system of indention show which gaging 

stations are on tributaries between any two stations on a main stem and the rank of the 

tributary on which each gaging station is situated.

The order of listing used before the publication of the 1951 report listed first all 

stations on the main stem from headwaters toward mouth, then all stations on the uppermost 

tributary to the main stem from the tributary's source to mouth, and then all stations 

from source to mouth of the uppermost tributary to the tributary.

EXPLANATION OF DATA

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

of discharge. In addition, observations of factors affecting the stage-discharge relation, 

weather records, and other information are used to supplement base data 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 fluctuations. 

Measurements of discharge are made with a current meter by the general methods adopted by 

the Geological Survey on the basis of experience in stream gaging since 1888. These 

methods are described in Water-Supply Paper 888 and are also outlined in standard textbooks on the measurement of stream discharge. Typical structures in use at gaging stations are shown in figure 1.

Rating tables giving the discharge for any stage are prepared from stage-discharge relation curves defined by discharge measurements. If extensions to the rating curves are 

necessary to define the extremes of discharge, they are made on the basis of indirect 

measurements of peak discharge (such as slope-area or contracted-opening measurements, 

computation of flow over dams or weirs, and by other methods), velocity-area studies, and 

logarithmic plotting. The application of the daily mean gage height to those rating 

tables gives the daily mean discharge, from which the monthly and the yearly mean discharge 

are computed. If the stage-discharge relation is subject to change because of frequent or 

continual change in the physical features that form the control, the daily mean discharge 

is determined by the shifting-control method, in which correction factors based on individual discharge measurements and notes by engineers and observers are used in applying 

the gage heights to the rating tables. If the stage-discharge relation for a station is 

temporarily changed by the presence of aquatic growth or debris on the control, the daily 

mean discharge is computed by what is essentially the shifting-control method.

FIGURE 1. GAGING-STATION STRUCTURES
6 SURFACE WATER SUPPLY, 1952, PART 1-B

At some gaging stations the stage-discharge relation Is affected1 by backwater from 

reservoirs, tributary streams, or other sources. This necessitates the use of the slope 

method In which the slope or fall In a reach of the stream Is a factor In determining 

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 stagedischarge relation Is affected by changing stage. If so, 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, and it becomes impossible to compute the discharge in the usual manner. Discharge for periods of Ice effect Is computed on the basis of the gage-height record and 

occasional winter discharge measurements, consideration being given to the available Information on temperature and precipitation, notes by gage observers and engineers, and comparable records of discharge for other stations In the same or nearby basins. If the 

stage-discharge relation is affected by ice, this Information is given in a note to the 

table. No mention Is made of occasional days of ice effect if the degree of accuracy of 

dally records Is not changed.

The data herein presented generally comprise a description of the station, a skeleton 

rating table, and a table showing the daily discharge and monthly and yearly discharge and 

runoff of the stream.

The description of the station gives the location, drainage area, records available, 

type and history of gages, average discharge, extremes of discharge, general remarks, and 

notations of revisions of the previously published record. The location of the gaging 

station and the drainage area are obtained from the most accurate maps available. River 

mileage, given under "Location" for some stations, is that determined and used by the Corps 

of Engineers unless otherwise noted. Under "Gage" are given the type of gage currently in 

use and the datum of the present gage above mean sea level, and a condensed history of the 

types of gages, locations, and datums of previous gages for which discharge records are 

generally equivalent to those at the present site. Under "Average discharge" Is given the 

average discharge for the number of years indicated. It Is not given for stations having 

fewer than five 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. If the maximum gage height did not occur 

at the same time as the maximum discharge, it is given separately. Information pertaining 

to the accuracy of the records and conditions which affect the natural flow at the gaging 

station is given under "Remarks."
EXPLANATION OP DATA 7

Previously published records of some stations have been found to be in error on the 

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

Listed therein are all the reports in which revisions have been published, 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 water years only one number is 

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

1933. If no daily, monthly, or annual figures of discharge are concerned 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 cubic feet per second 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 cubic feet 

per second 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.

Skeleton rating tables are published for all stations except those at which the daily 

discharge for the greater part of the open-water period was determined by the shiftingcontrol method, the slope method, or other special methods involving an equivalent adjustment to the gage height of more than one-tenth foot.

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

sudden or rapid fluctuation, the daily 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, which must be obtained by averaging 

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

obtaining the daily mean discharge from a continuous gage-height graph and containing, as 

an essential element, a curve representing the stage-discharge relation at the station. 

For stations equipped with nonrecording gages, the table of daily discharge gives the 

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

readings, or to 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 daily discharge, the values for the maximum day and the minimum day for 

each month are underlined. If the value is repeated, It is underlined only on the first 

day of its occurrence.

In the monthly summary below the daily table, the line headed "Total" gives the sum of 

the daily values; it is the total cfs-days for the month. The line headed "Mean" gives 

the average flow in cubic feet per second during the month. Runoff for the month may be 

expressed in cubic feet per second per square mile (line headed "Cfsm"), or in inches (line 

headed "In."), or in acre-feet (line headed "Ac-ft"). Values for cubic feet per second per
8 SURFACE WATER SUPPLY, 1952, PART 1-B

square mile and runoff, in inches, are omitted if the drainage area includes large noncontributing areas, or if the average annual rainfall over the drainage basin is usually less 

than 20 inches.

In the yearly summary below the monthly summary, the values of maximum are the maximum 

daily discharges, not the momentary discharges when the water was at crest stage. Likewise, the minimums in this summary are the minimum daily discharges.

Peak discharges and the times of their occurrence and corresponding gage heights of 

most stations are listed below the table of daily and monthly discharge. 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.

Footnotes to the table of daily discharge indicate periods when discharge was computed 

or estimated by unusual or special methods during periods of no gage-height record and ice 

effect, or by other effects that reduce the degree of accuracy of the records. Days on 

which discharge measurements were made are indicated by asterisk and footnote unless they 

were made at frequent regular intervals, in which instance the general frequency of discharge measurements is given under "Remarks" in the station description.

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 the reservoir are published, 

but it is omitted from succeeding reports.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of streamflow data depends primarily on (1) the stability 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 discharge, and interpretation of records.

The station description states the degree of accuracy of the records. "Excellent" indicates that, in general, the error in the daily records is believed to be less than 5 percent; "good," less than 10 percent; "fair," less than 15 percent; and "poor," probably 

more than 15 percent. The records of monthly and yearly mean discharge and runoff are, 

in general, more nearly accurate than the daily records.

Runoff at some stations, as indicated by the monthly mean, may vary widely from natural 

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

evaporation due to artificial causes, or to other factors. For such stations, values of 

cubic feet per second per square mile and runoff, in inches, are not published unless 

storage or diversion records are included to indicate the extent of the regulation or diversion, or unless satisfactory adjustments can be made for changes in contents of reservoirs or for other changes incident to use and control. Evaporation from a reservoir is 

not included in the adjustments for changes in reservoir contents, unless it is so stated. 

Even at those stations where adjustments are made, large errors in computed runoff may 

occur when relatively large negative adjustments are made or when evaporation is large in 

comparison with the observed discharge.
PUBLICATIONS

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 actually show the water supply available at the stations for further development, 

because water must first be supplied to existing irrigation systems.

PUBLICATIONS

To facilitate publication of the annual series of reports, the area of the United 

States is divided into 14 parts whose boundaries coincide with certain natural drainage 

lines. Formerly, the results of streamflow measurements were published in 14 volumes, one 

for each of the 14 parts. Beginning with the reports for 1951, the records are published 

in 18 volumes, there being 2 volumes each for Parts 1, 2, 3, and 6. Tiro boundaries of the 

various parts are indicated by the following list and the map in figure 2.

The records at most of the stations discussed in these reports extend over many 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 are listed in the same order as the 

streams and gaging stations in the body of the report. An index of the records obtained 

before 1904 has been published in Water-Supply Paper 119.

Each of the reports on the surface-water supply for the year 1939 (Water-Supply Paper 

871 for the North Atlantic slope basins, New York to York River) contains, for the area 

included in that report, a summary of yearly discharge at gaging stations at which 10 or 

more complete years of record had been collected. These summaries were reprinted separately.

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

annual series of water-supply papers. The following table lists reports of this type for 

the North Atlantic slope basins, New York to York River.

ffote. The Soil Conservation Service, United States Department of Agriculture, has been collecting 

records of runoff from the following selected areas in the North Atlantic slope basins, New York to 

York River: Beginning in 1938, from 5 areas of less than 75 acres each near Boonsboro, Md.; beginning in 1939, from 10 areas of less than 20 acres each near College Park, Md.; and beginning in 

1948, from one area of 500 acres and one area of 4,000 acres near Staunton, Va.

HYDROLOGIC CONDITIONS

Streamflow during the 1952 water year was well above normal In most of the North 

Atlantic slope basins, New York to York River. Record-breaking floods occurred In Delaware and Susqueharma River basins, Pennsylvania, In March and In Maryland during the 

hurricane of August 31 to September 1. Local flooding occurred In Maryland In May, In 

New York In June, and In Delaware and Pennsylvania In July. For three key gaging stations 

In the area covered by this report, a comparison of monthly and yearly mean discharges 

during the 1952 water year with the median discharge for the 25-year period 1921-45 is 

shown in figure 3 on the following page.

 mum gage height, 1.75 ft Nov. 1 (backwater from high tide), from reconstructed gageheight graph; minimum discharge, 0.70 cfs Oct. 6 (gage height, 0.118. ft, from recorded 

range in stage).

1950-52: Maximum discharge, that of Aug. 23, 1952; maximum gage height, 3.33 ft 

Nov. 25, 1950 (backwater from high tide); minimum discharge, 0.39 cfs (result of freezeup) Feb. 9, 1951 (gage height, 0.086 ft).

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

SFTackwater from debris, aquatic vegetation, or high tide, which are fair. Plow 

occasionally regulated at outlet of pond 40 ft above station. Diversion from this pond 

by New York State Fish Hatchery bypasses station. This station is operated in connection with an inventory of water resources on Long Island. In addition to records of 

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

in water-supply papers.

Location. Lat 40°50'55", long. 73°13'25", on left bank half a mile dovmstream from 

Blydenburgh Pond and 1 mile southwest of Smithtown, Suffolk County.

Drainage area. About 27 sq mi.

Records available. October 1943 to September 1952.

Gage. Water-stage recorder and concrete control. Datum of gage is 9.59 ft above mean 

sea level, datum of 1929.

Average discharge. 9 years, 39.62 cfs.

Extremes. Maximum discharge during year, 100 cfs June 1 (gage height, 1.045 ft); minimum, 28.7 cfs Dec. 14 (gage height, 0.582 ft); minimum daily, 30 cfs Oct. 3-6.

1943-52: Maximum discharge, 147 cfs Sept. 14 1944 (gage height, 1.32 ft, 0.02 ft 

backwater from obstruction in channel), from rating curve extended above 70 cfs on 

basis of logarithmic plotting; minimum, 18.6 cfs Feb. 9, 1951 (gage height, 0.460 ft); 

minimum daily, 20.0 cfs Oct. 6, 1947.

Remarks. Records excellent except those for periods of backwater from aquatic vegetation, fragmentary gage-height record, or bypassed flow, which are good. Some regulation caused 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 water resources on Long Island. 

In addition to records of streamflow, records of ground-water levels are collected, 

some of which are published in water-supply papers.

Remarks. Records excellent except those for periods of doubtful or 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 water resources on Long Island. In addition to records of streamflow, records of ground-water levels are collected, some of which are published in 

water-supply papers.

STREAMS ON LONG ISLAND 31

Sampawams Creek at Babylon, N. Y.

Location.--Lat 40«42'15", long. 73B 18'50', on left bank at upstream side of John Street 

Bridge In Babylon, Suffolk County, 180 ft downstream from Long Island Railroad, and 

3,000 ft upstream from mouth.

Drainage area. About 23 sq ml.

Records available. October 1944 to September 1952.

Page. Water-stage recorder and concrete control. Datum of gage Is 6.70 ft above mean 

sea level, datum of 1929.

Average discharge. 8 years, 8.70 cfs.

Extremes. Maximum discharge during year, 36.6 cfs Apr. 28 (gage height, 0.895 ft); minimum, 3.35 cfs Oct. 2 (gage height, 0.268 ft); minimum daily, 3.48 cfs Oct. 2.

1944-52: Maximum discharge, 49.9 cfs July 13, 1948 (gage height, 1.009 ft), from 

rating curve extended above 30 cfs by logarithmic plotting; minimum, 3.26 cfs Oct. 5, 

1945; minimum gage height, that of Oct. 2, 1951; minimum daily discharge, 3.4S cfs 

Oct. 5, 1945.

Remarks. Records excellent except those for periods of backwater from debris, which are 

good, and those for periods of backwater from aquatic vegetation or weeds below 

control, which are fair. Slight Intermittent regulation by automatic pumping station 

at railroad upstream and occasional regulation from changing stoplogs in fish ponds 

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

on Long Island. In addition to records of streamflow, records of ground-water levels 

are collected, some of which are publlsed in water-supply papers.

Revisions. W 1141: Drainage area.

Rating tables, water year 1951-52, except periods of backwater from aquatic 

vegetation, debris, or weeds below control (gage height, In feet, and 

discharge. In cubic feet per second)

STREAMS ON LONG ISLAND 35

Wantagh Stream at Wantagh, N. Y.

Location. Lat 40°40'50", long. 73°30'45", on right bank on Wantagh Parkway at northwest 

boundary of village of Wantagh, Nassau County.

Drainage area. About 17 sq mi.

Records; available. June to October 1883, July to October 1903 (fragmentary, in Professional Paper 44), September 1937 to September 1952.

Gage. Water-stage recorder and concrete control. Datum of gage is 16.88 ft above mean 

sea level, adjustment-of 1912. June to October 1883, determinations of flow by 

various methods at different site and datum. July to October 1903, staff gages on 

two channels near same site at different datum.

Average discharge. 15 years (1937-52), 8.88 cfs.

Extremes. Maximum discharge during year, 340 cfs June 1 (adjusted to include flow bypassing station); maximum gage height, 2.566 ft June 1; minimum discharge, 4.20 cfs 

Oct. 1 (gage height, 0.400 ft); minimum daily, 4.32 cfs Oct. 3.

1903, 1937-52: Maximum discharge, that of June 1, 1952; maximum gage height, that

minimum daily, 1.84 cfs Sept. 12, 1943.

Remarks. Records excellent except those for periods of backwater from aquatic vegetaETon or debris, or diversion around station, which are good, and those for periods of 

fragmentary or no gage-height record, which are fair. Flow regulated intermittently 

by Browning Pond, half a mile above station. This station is operated in connection 

with an inventory of water resources on Long Island. In addition to records of streamflow, records of ground-water levels are collected, some of which are published in 

water-supply papers.

Location. Lat 43'18"40", long. 73'52"00", on left bank 1 mile downstream from Stewarts 

Bridge, 1.1 miles west of Hadley, Saratoga County, 1.4 miles upstream from mouth, and 

1.5 miles downstream from Stewarts Bridge hydroelectric plant.

Drainage area. 1.055 sq mi.

Records available. October 1951 to September 1952.

;e. Water-stage recorder. Datum of gage is 582.00 ft above mean sea level, datum of 

29, supplementary adjustment of 1943.

Extremes.--Maximum discharge during year, 6,930 cfs May 14, 28 (gage height, 7.00 ft); minimum, 26 cfs Aug. 18 (gage height, 0.59 ft); minimum daily, 39 cfs May 8.

Remarks. Records excellent except those for periods of fragmentary, doubtful, or no gageheight record, which are good. Plow completely regulated by Sacandaga Reservoir (see p. 

48); no discharge over spillway during year. Extensive diurnal fluctuation caused by 

release of water from Sacandaga Reservoir, through Elmer J. West hydroelectric station, 

as directed by Board of Hudson River Regulating District and Stewarts Bridge hydcoelectric station.

Cooperation. Discharge computed by Board of Hudson River Regulating District from rating 

developed by Geological Survey. Records collected by Niagara Mohawk Power Corp., in 

connection with a Federal Power Commission project.

debris, which are fair. Plow regulated in accordance with requirements of Champlain 

Canal. Operation of feeder discontinued at 5 p.m. Dec. 3, 1951, and resumed at 2 p.m. 

Apr. 28, 1952. Discharge shown during intervening period consists of leakage through 

headgates and runoff from area tributary to feeder above station. This flow may 

continue during period of no record. During canal navigation season, a portion of the 

flow is diverted into Lake Champlain basin through summit level of Champlain Canal at 

Dunham Basin.

66 HUDSON RIVER BASIN

West Canada Creek at Hinckley, N. Y.

Location. Lat 43°18'20", long. 75°07'10", on right bank at Hinckley, Oneida County, 

1 mile downstream from Hinckley Dam, if miles east of Prospect, and 65 miles upstream 

from Steuben Creek.

Drainage area. 375 sq mi.

Records available. June 1919 to September 1952.

Gage. Water-stage recorder. Datum of gage is 1,134.00 ft above mean sea level (Utica 

Gas & Electric Co. datum).

Average discharge. 33 years, 1,006 cfs (unadjusted).

Extremes. Maximum discharge during year, 6,560 cfs Apr. 21 (gage height, 7.61 ft); mini- 

 mum', 254 cfs Oct. 12, 13 (gage height, 3.50 ft); minimum daily, 365 cfs July 13.

1919-52: Maximum discharge, 17,100 cfs Oct. 2, 1945, computed on basis of peak 

flow over dam; maximum gage height, 12.94 ft Oct. 2, 1945, from high-water mark in 

gage well (backwater from debris); minimum discharge, less than 1 cfs Aug. 31, 1924 

(gage height, 2.50 ft); minimum daily, 75 cfs Aug. 31, 1919.

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

goocT. Since 1916, flow regulated by Hinckley Reservoir (usable capacity, 3,320,000,000 

cu ft). Comparatively small diversion from Hinckley Reservoir for Utica water supply.

68 HUDSON RIVER BASIN 

West Canada Creek at Kast Bridge, N. Y.

Location. Lat 43°04 I 15", long. 74°59'25", on left bank 600 ft downstream from highway 

bridge at Kast Bridge station on New York Central Railroad, Herkimer County, 1 mile 

downstream from North Creek, and 4 miles upstream from mouth and Herkimer.

Drainage area. 556 sq mi.

Records available. May 1905 to December 1909 (1905-6, gage heights and discharge measurements only), January 1912 to December 1913, and October 1920 to September 1952 in 

reports of Geological Survey. January 1910 to December 1911 and January 1914 to 

September 1920 in reports of State engineer and surveyor.

Gage. Water-stage recorder. Datum of gage is 438.99 ft above mean sea level, datum of 

1929. Prior to Sept. 18, 1920, tape gage at former highway bridge 500 ft upstream at 

different datum.

Average discharge. 32 years (1920-52), 1,348 cfs.

3 during year, 6,690 cfs Apr. 21 (gage height, 5.11 ft); minept. 30 (gage height, 1.59 ft); minimum daily, 355 cfs

Extremes. Maximum discharg 

imum, 177 cfs Aug. 23, £ 

Sept. 24.

1920-52: Maximum discharge, 20,500 cfs Oct. 2, 1945 (gage height, 8.08 ft); maximum gage height, 10.47 ft probably Feb. 17, 1943, from floodmark in gage well (ice 

Jam); minimum discharge, 20 cfs Sept. 3, 1929 (gage height, 0.90 ft); minimum daily, 

59 cfs Sept. 2, 1929.

Maximum discharge known, 23,300 cfs Mar. 26, 1913, from reports of State engineer 

and surveyor.

Remarks. Records excellent except those for periods of ice effect or fragmentary gageheight record, which are good. Since 1916, flow slightly regulated by Hinckley 

Reservoir (usable capacity, 3,320,000,000 cu ft). Diurnal fluctuation at low and 

medium flow caused by powerplants above station. Diversion at Trenton Palls by Ninemile feeder during canal navigation season.

Revisions. W 741: Drainage area.

HUDSON RIVER BASIN 69

Mohawk River near Little Falls, N. Y.

Location. Lat 43'00>5011 , long. 74°46'4Q", on left bank 1,800 ft downstream from Rocky 

Rift Dam, 2 miles upstream from East Canada Creek, and 4j miles southeast of city of 

Little Palls, Herkimer County.

Drainage area. 1,348 sq mi.

Records available. February to April 1901, October 1927 to September 1952 in reports of 

Geological Survey. November 1923 to September 1927 in files of State Department' of 

Public Works.

Gage. Water-stage recorder. Datum of gage is 310.0 ft above mean sea level (Barge 

(Tanal datum). February to April 1901, staff gage 1,500 ft upstream at different 

datura.

Average discharge. 25 years (1927-52), 2,826 cfs.

Extremes. Maximum discharge during year (river channel only), 11,900 cfs Apr. 6 (gage 

height, 12.10 ft); minimum (river channel only), 459 cfs Aug. 24 (gage height, 4.38 

ft); minimum daily (including canal), 724 efs Sept. 29.

1927-52: Maximum discharge (river channel only), 25,300 efs Oct. 3, 1945 (gage 

height, 17.80 ft); minimum (river channel only), 214 cfs Aug. 18, 1949 (gage height, 

3.75 ft); minimum daily (including canal), probably not less than 463 cfs Sept. 2, 

1934.

Remarks. Records excellent except those for periods of ice effect or doubtful gageheight record, which are fair. Records of daily discharge include diversion at Rocky 

Rift Dam into Barge Canal for power and lockage at lock 16, near St. Johnsville. 

During canal navigation season", water is received from Black River 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 Utiea. Diurnal fluctuation oaused by powerplants and locks and dams on 

Barge Canal. Appreciable regulation by Delta and Hinckley Reservoirs (combined 

usable capacity, 6,120,000,000 cu ft).

Mohawk Power Corp., l£ miles upstream from mouth, and 3? miles northwest of 

St. Johnsville.

Drainage area.--^91 sq mi.

Records available. December 1945 to September 1952.

Sage. Water-stage recorder. Datum of gage is 335.70 ft above mean sea level, datum of 

1929, supplementary adjustment of 1943.

Average discharge. 6 years (1946-52), 754 cfs.

Extremes. Maximum discharge during year, 10,700 cfs Apr. 6 (gage height, 6.78 ft), 

result of loss of flashboards; minimum, 11 cfs June 26, 27 (gage height, 0.96 ft); 

minimum daily, 12 cfs Aug. 24, 30, 31, Sept. 7, 13, 20, 21, 28.

1945-52: Maximum discharge, 12,200 cfs Mar. 30, 1951 (gage height, 7.03 ft); minimum, 0.6 cfs Sept. 7, 1947; minimum gage height, 0.71 ft Sept. 7, 1947, Sept. 24, 

1949; minimum daily discharge, 5.9 cfs Sept. 13, 1947.

Maximum stage known, 9.0 ft Oct. 2, 1945, from floodmarks (discharge, 24,000 cfs, 

by slope-area determination of peak flow).

Remarks. Records good except those for periods of doubtful gage-height record, which 

are fair. Extensive diurnal fluctuation and slight regulation caused by powerplants 

above station. City of Little Falls diverts about 5 cfs for municipal supply.

74 HUDSON RIVER BASIN

Mohawk River at Cohoes, N. Y.

Location. Lat 42°47'05", long. 73°42'25", on right bank at School Street plant of

Niagara Mohawk Power Corp. in Cohoes, Albany County, and If miles upstream from mouth.

Drainage area. 3,456 sq mi.

Records available. July 1925 to September 1952.

Gage. Water-stage recorder. Datum of gage is 49.13 ft above mean sea level, datum of 

1929, supplementary adjustment of 1943. Prior to Oct. 19, 1925, powerplant gage.

Average discharge. 27 years, 5,741 cfs.

Extremes. Maximum discharge during year, 60,800 cfs Apr. 6 (gage height, 18.52 ft);

 minimum daily, 170 cfs Sept. 14.

1925-52: Maximum discharge, 130,000 cfs Mar. 19, 1936 (gage height, 22.57 ft); 

from rating curve extended above 34,500 cfs by logarithmic plotting; minimum, 6 cfs 

Sept. 28, 1941 (gage height, 3.40 ft); minimum daily, 23 cfs Aug. 24, 1941.

Remarks. Records excellent except those below 500 cfs, which are fair. Records include 

small diversion Just above gage for Cohees 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)nand 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. Most of flow of Schoharie Creek above Gilboa Dam, a tributary of 

Mohawk River, is diverted out of basin through Shandaken tunnel for water supply of 

City of New York. Slight regulation by storage principally in Delta, Hinckley, and 

Schoharie Reservoirs (combined capacity, 8,738,000,000 cu ft). Extensive diurnal 

fluctuation caused by School Street powerplant.

 Just upstream from Troy Lock and Dam, half a mile downstream from 5th branch Mohawk

Drainage'area.. 8.090 sq mi, approximately (including that above site of auxiliary gage).

Records available. February 1946 to September 1952. ,,.,*. «.

flake. Water-stage recorder. Datum of gage is 0.31 ft below mean sea level, datum of

~^T929 (Corps o? Engineers benchmark). Since July 1, 1946, auxiliary water-stage recorder on bypass channel at datum 10.59 ft higher.

Average discharge. 6 years, 14,610 cfs (including flow through bypass channel).

Extremes [main channel). Maximum daily discharge during year, 92,700 cfs Apr. 6; maximum gage height. 22.78 ft Apr. 6j minimum daily discharge, 2.,360 ofs July 5; minimum

^me^' Maximum discnarge, 181,000 cfs Dec. 31, 1948 (gage height, 27.05 ft, from 

high-water mark in gage well!; maximum daily, 141,000 cfs Dec, 31, 1948, Jan 11' 0^49; 

minimum daily, 1,270 cfs Sept. 5, 1949s minimum gage height, 13.9| ft Sept. 2, 1946.

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

information by Corps of Engineers (discharge, 215,000 cfs). Flood e.f Mar. 28, 1913, 

prior to construction of Sacandaga Reservoir and Troy Lock and Dam, reached a stage 

about 0.2 ft higher upstream from former dam near same site. Downstream from dams, 

flood of 1913 was about 3.3 ft higher than flood of 1936, from information by Corps 

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

 Backwater from partly constructed flashboards, or shifting control, which are fair. 

Records of main channel include flow over spillway, through wheels, and through lock. 

Records of flow in bypass channel, which enters Hudson River 1* miles downstream, is 

shown separately. Appreciable regulation by Sacandaga Reservoir (see p.48 ), Indian 

Lake Reservoir (see p. 41), and Delta, Hinckley and Schoharie Reservoirs (combined 

capacity, 8,738,000,000 cu ft). Diurnal fluctuation caused by powerplants above station. Diversion above station for water supply for New York City (see records for 

Mohawk River at Cohoes and Schoharie Creek at Burtonsville). During canal navigation 

season, water is received from Black River basin through Black River Canal (flowing 

south) and Lansing Kill, and possibly from Chenango River basin through Oriskany 

Creek feeder. Water is diverted into (or may occasionally be received from) Oswego 

River basin through summit level of Barge Canal between New London and Utica. Water 

is diverted into St. Lawrence River basin through Glens Falls feeder and Champlain 

Canal (see p. 52). ... _ . Cooperation. Powerplant records furnished by Ford Motor Co. in connection with a FetteraTTower Commission project.

Discharge, in cubic feet per second, water year October 1951 to September 1952

 TT929. March 1906 to May 1914, tape and weight gage at same site at different datum.

Average discharge. 27 years (1906-9, 1928-52), 477 cfs.

Extremes. Maximum discharge during year, 6,270 cfs June 2 (gage height, 6.63 ft); mini-

 mum, 8.6 cfs Aug. 30 (gage height, 0.02 ft); minimum daily, 30 cfs Aug. 30.

1906-14, 1928-52: Maximum discharge, 29,800 cfs Dec. 31, 1948 (gage height, 19.8 

ft, from floodmark); minimum, less than 3 cfs Aug. 12, 1911 (gage height, 25.85 ft, 

datum then in use); minimum daily, 4 cfs Sept. 3, 1913.

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

 record, which are fair. Diurnal fluctuation and slight regulation at low and medium 

flow caused by power and industrial plants above station.

84 HUDSON RIVER BASIN 

Rondout Creek near Lackawack, N. Y.

Location. Lat 41°46'30", long. 74°24'10", on left bank at downstream side of highway 

bridge known as Wilburs Bridge, 2j miles southeast of Lackawack, Ulster County, and 

3 miles downstream from Merriman Dam (Rondout Reservoir).

Drainage area. 100 sq mi.

Records available. October 1931 to September 1952 in reports of Geological Survey. February 1906 to April 1910 (at Honk Falls) and May 1910 to September 1925 in reports of 

State engineer and surveyor. May 1910 to September 1952 (monthly discharges) in reports 

of Board of Water Supply, New York City.

Gage. Water-stage recorder and concrete control. Datum of gage is 601.07 ft above mean 

sea level (levels by Board of Water Supply,New York City). Feb. 13, 1906, to Apr. 30, 

1910, at site 3 miles downstream at different datum. May 1, 1910, to Feb. 15, 1939, 

at site half a mile downstream at datum 13.40 ft lower than present datum.

Extremes. Maximum discharge during year. 731 cfs June 1 (gage height, 3.20 ft); minimum, 

0.9 cfs Aug. 2 (gage height, 0.065 ft).

1906-52: Maximum discharge, 26,700 cfs Aug. 26, 1928 (slope-area determination by 

Board of Water Supply,New York City); minimum daily, 0.3 cfs Sept. 29, 1948, Aug. 1, 

9, 10, 21-28', 1949.

Remarks. Records good except those for periods of ice effect and those below 2 cfs,

which are fair. Subsequent to May 9, 1951, when the diversion tunnel through Merriman 

Dam was plugged, the record represents merely the flow passing Merriman Dam, augmented 

by natural flow between dam and gaging station. Entire flow above Merriman Dam (drainage area, 94.4 sq mi), except for small releases, diverted for water supply of New York 

City.

HUDSON RIVER BASIN 85

Rondout Creek at Rosendale, N. Y.

Loeation.--Lat 41°50'35", long. 74°05'10", on left bank 150 ft upstream from upper highway bridge in Rosendale, Ulster County, and 3 miles upstream from Wallkill River.

Drainage area. 386 sq mi.

Records available. July 1901 to November 1903, January 1906 to December 1913, and August 

1926 to September 1952 in reports of Geological Survey. January 1914 to January 1919 

in reports of State engineer and surveyor.

Gage. Water-stage recorder. Datum of gage is 42.83 ft above mean sea level, datum of 

T929, supplementary adjustment of .1943. Prior to January 1919, chain gage on highway 

bridge 150 ft downstream at datum 4.0 ft lower.

Extremes. Maximum discharge during year, 19,600 cfs June 1 (gage height, 16.13 ft); minimum, 16 cfs Sept. 30 (gage height, 1.41 ft); minimum daily, 45 cfs Oct. 5.

1901-3, 1906-19, 1926-52: Maximum discharge, 27,300 cfs Aug. 27, 1928 (gage height, 

21.9 ft), from rating curve extended above 15,000 cfs by logarithmic plotting; minimum, 

6.0 cfs Oct. 1, 1948 (gage height, 1.23 ft); minimum daily, 8.5 cfs Sept. 30, 1948.

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

diurnal fluctuations during low and medium flow caused by powerplant above station. 

Subsequent to May 9, 1951, when the diversion tunnel through Merriman Dam was plugged, 

the record indicates natural flow from 292 sq mi, the drainage area above Merriman Dam 

being 94.4 sq mi. Entire flow above Merriman Dam, except for small releases, diverted 

from Rondout Reservoir for water supply of New York City.

Revisions (water years). W 641: Drainage area. W 756: 1933.

Pequannock); minimum daily, 41 cfs Oct. 9, 13-15, 1941. 

Remarks. Records good except those for periods of no gage-height record for the main

 spillway, which are fair. Water diverted from reservoirs on Pequannock and Wanaque 

Rivers for municipal supply. Plow regulated by Oak Ridge, Canistear, Clinton, and Echo 

Lake Reservoirs on Pequannock River (see p.' 105), and by Greenwood Lake and Wanaque 

Reservoir on Wanaque River (see pp. 106, 113) which have a combined capacity of 

5,944,000,000 cu ft. Some diurnal fluctuation at low flow caused by powerplant on 

Wanaque River.

Lackawaxen River at Hawley, Pa.

Location. Lat 41°28'30", long. 75°10'05", on left bank at Hawley, Wayne County, 300 ft 

downstream from Wallenpaupack Creek and 1,000 ft downstream from highway bridge. Records exclude that of Wallenpaupack Creek which is diverted around station to hydroelectric plant downstream.

Drainage area. 290 sq mi (excludes that of Wallenpaupack Creek, which is 228 sq mi).

Records available. August 1938 to September 1952 in reports of Geological Survey. July 

1908 to September 1917, October 1917 to December 1919 (gage heights and discharge measurements only), and August 1938 to September 1941 in reports of Pennsylvania Department 

of Forests and Waters.

Gage. Water-stage recorder. Datum of gage is 869.00 ft above mean sea level, datum of 

1929, New York-Pennsylvania supplementary adjustment of 1943. Prior to 1938, chain 

gage at site 1,000 ft upstream at same datum.

Average discharge.--21 years (1909-12, 1913-17, 1938-52), 487 cfs.

Extremes. Maximum discharge during year, 21,700 cfs July 10 (gage height, 11.78 ft), from 

rating curve extended above 12,000 cfs as explained below; minimum, 43 cfs Oct. 7 (gage 

height, 1.33 ft).

1908-19, 1938-52: Maximum discharge, 50,000 cfs May 23, 1942 (gage height, 20.1 ft, 

from floodmark in gage shelter), from rating curve extended above 12,000 cfs on basis of 

slope-area determination of peak flow; minimum daily, 7 cfs Aug. 20, 1911.

Flood of March 1936 reached a stage of 13.9 ft, from floodmark (discharge, 27,600 cfs).

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

which are fair.

Revisions (water years). W 951: 1938-41.

Drainage area. 3,076 sq mi.

Records available. October 1904 to September 1952.

Gage, Water-stage recorder. Datum of gage is 415.35 ft above mean sea level, datum of 

~T:929. Prior to June 20, 1914, chain gage at highway bridge 250 ft upstream at same

datum operated by U. S. Weather Bureau. June 20, 1914, to Aug. 13, 1928, staff and/or

chain gages at highway bridge 250 ft upstream at present datum. 

Average discharge. 48 years, 5,588 cfs. 

Extremes. Maximum discharge during year, 81,000 cfs July 10 (gage height, 13.50 ft)

 imum, 546 cfs Aug. 31 (gage height, 1.44 ft); minimum daily, 586 cfs Aug. 31.

1904-52: Maximum discharge, 140,000 cfs May 23, 1942 (gage height, 17.76 ft), from 

rating curve extended above 89,000 cfs by logarithmic plotting; minimum, 175 cfs 

Sept. 23, 1908 (gage height, 0.6 ft); minimum daily, 175 cfs Sept. 23, 1908.

Maximum discharge known, 205,000 cfs Oct. 10, 1903 (gage height, 23.1 ft, reported

plotting and velocity-area studies; maximum stage known, 25.5 ft Mar. 8, 1904 

(ice Jam).

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

record, which are good. Large diurnal fluctuations at medium and low flow caused by 

powerplants on tributary streams. Plow regulated by Lake Wallenpaupack and by Toronto, 

Cliff Lake, and Swinging Bridge Reservoirs (combined capacity, 12,300,000,000 cu ft).

Records available.--August to October 1903, August 1909 to April 1914 (gage heights and 

discharge measurements, also twice-daily figures of discharge for January 1911 to 

December 1912), and July 1937 to September 1952 in reports of Geological Survey. August 

to October 1903 and August 1909 to December 1913 in reports of State engineer and 

surveyor. August to October 1903 published as Havesink River at Godeffroy.

Gage.--Water-stage recorder. Altitude of gage is 460 ft (from topographic map). August to 

October 1903 staff gage at datum 1.02 ft lower. Aug. 22, 1909, to Jan. 21, 1910, staff 

gage and Aug. 1, 1910, to Apr. 30, 1914, chain gage, at datum 2.00 ft lower.

Average discharge. 15 years (1937-52), 635 cfs.

Extremes.--Maximum discharge during year, 14,500 cfs July 10 (gage height, 10.36 ft); minimum, 114 cfs Oct. 7 (gage height, 3.20 ft).

1903, 1909-14, 1937-52: Maximum discharge, 20,000 cfs Nov. 26, 1950 (gage height, 

11.79 ft); practically no flow July 21, 1911 (gage height, -0.3 ft, present datum).

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

to 1949, diurnal fluctuations at low and medium flow caused by powerplant at Cuddebackville.

from rating curve extended above 90,000 cfs; minimum, 385 cfs Aug. 28, 29, 1949 (gage

height, 3.76 ft); minimum daily, 428 cfs Sept. 27, 1943.

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

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

164,500 cfs, from present rating curve extended above 90,000 cfs). 

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

vegetation, which are fair. Diurnal fluctuation at medium and low flow caused by

powerplants on tributary streams. Flow regulated by Lake Wallenpaupack and by

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

cu ft).

LEIPSIC RIVER BASIN 

Leipsic River near Cheswold, Del.

243

Location. Lat 39°13'56", long. 75°37'56", on left bank 75 ft downstream from highway 

bridge, 0.4 mile downstream from confluence of Taylor and Pinks Branches, 1.9 miles 

east of Kenton, and 2.6 miles northwest of Cheswold, Kent County.

Drainage area. 9.2 sq mi, approximately.

Records available. October 1931 to October 1933, April 1943 to September 1952.

Gage. Water-stage recorder. Oct. 1, 1931, to Oct. 31, 1933, staff gage at bridge 75 ft 

upstream at different datum. Apr. 9, 1943, to Aug. 9, 1951, staff gage and crest-stage 

indicator at bridge 75 ft upstream from present site at present datum; gage read twice 

daily.

Average discharge. 11 years (1931-33, 1943-52), 11.2 cfs.

Extremes.--Maximum discharge during year, 441 cfs July 9' (gage height, 5.44 ft); minimum, 

2.5 cfs Oct. 6, 7.

1931-33, 1943-52: Maximum discharge, that of July 9, 1952, but may have been 

greater Aug. 23, 1933 (gage height, 6.1 ft, present site, datum then in use, from graph 

based on gage readings); minimum, 0.9 cfs Aug. 19, 1931.

Revisions. The maximum discharge for the water year 1933 as published in WaterSupply Paper 741 is believed to be too low and should not be used.

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

sea level, datum of 1929.

Extremes.--Maximum discharge during year, 2,420 cfs Sept. 1 (gage height, 6.36 ft), from 

rating curve extended above 490 cfs on basis of slope-area determination at gage 

height 5.24 ft and computation of peak flow over dam three-quarters of a mile upstream; 

minimum, 2.1 cfs Oct. 7 (gage height, 1.48 ft); minimum daily, 7.1 cfs Oct. 1, 3, 4, 6.

1948-52: Maximum discharge, that of Sept. 1, 1952; minimum, that of Oct. 7, 1951; 

minimum daily, 5.3 cfs Sept. 30, 1951.

Revisions.--The maximum discharge for the water year 1949 has been revised to 1,120 

cfs July 13, 1949 (gage height, 4.19 ft), superseding figure published in Water-Supply 

Paper 1171.

Remarks.--Records good except those for periods of ice effect or doubtful or no gageheight record, which are fair. Some regulation by paper mills above station.

Records available. January 1930 to September 1952.

Gage.--Water-stage recorder. Datum of gage is 963.94 ft above mean sea level, adjustment 

of 1912 (levels by Corps of Engineers). Prior to Feb. 9, 1937, wire-weight gage on 

bridge at same datum.

Average discharge. 22 years, 802 cfs.

Extremes.--Maximum discharge during year, 32,300 cfs Mar. 11 (gage beight, 17.71 ft); minimum, 30 cfs Sept. 14, 15 (gage height, 2.84 ft).

1930-52: Maximum discharge, 75,000 cfs May 28, 1946 (gage height, 22.87 ft, from 

high-water mark in gage house), from rating curve extended above 31,000 cfs on basis of 

velocity-area and slope-area studies at gage height 19.2 ft and conveyance study and 

slope-area determination at gage height 22.87 ft; minimum, 6.1 cfs Sept. 1, 1939 (gage 

height, 2.81 ft).

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

which are good, and those for periods of no gage-height record, which are fair.

Revisions (water years). W 871: 1938.

SUSQUEHANNA RIVER BASIN 305

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

Location.--Lat 42°18'50", long. 77°39'05", on right bank 200 ft (revised) upstream from 

Brie Tiailroad bridge in Hornell, Steuben County, 0.25 mile upstream from Crosby Creek, 

and 1.5 miles downstream from Canacadea Creek.

Drainage area. 159 sq mi.

Records available.--August 1942 to September 1952.

Gage.--Water-stage recorder and concrete control. Datum of gage is 1,131.10 ft above 

mean sea level (Corps of Engineers benchmark).

Average discharge.--10 years, 173 cfs.

Extremes.--Maximum discharge during year, 3,280 cfs Mar. 11 (gage height, 8.51 ft); minimum daily, 10 cfs Sept. 12-14.

1942-52: Maximum discharge, 9,340 cfs May 26, 1943 (gage height, 13.30 ft), from 

rating curve extended above 3,700 cfs on basis of critical-depth determination of peak 

flow; minimum, 9.3 cfs Mar. 4, 1947; minimum gage height, 0.76 ft Nov. 18, 20, 1944.

Remarks. Records good except those for periods of ice effect, fragmentary or no gageheight record, shifting control, or partly obstructed intake, which are fair. Records 

include daily diversion (about 1.5 cfs) Just above control by Erie Railroad Company. 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 cfs for municipal supply from 

Carrington Creek, a tributary above station; sewage enters river below gage. Since 

November 1939, flood flows regulated by Arkport Reservoir (see p. 301), and, since October 1948, by Almond Reservoir.

Cooperation. Records of diversion above station furnished by Erie Railroad Co. and, from 

Carrington Creek, by city of Hornell.

Discharge, in cubic feet per second, water year October 1951 to September 1952

312 SUSQUEHANNA RIVER BASIN

Cohocton River near Campbell, N. Y.

Location.--Lat 42°15'10", long. 77°13'00", on left bank just downstream from highway

 bridge, ij miles upstream from Michigan Creek and 2 miles upstream from Campbell, 

Steuben County.

Drainage area. 472 sq mi.

Records available.--July 1918 to September 1952.

Gage.--Water-stage recorder. Datum of gage is 1,016.58 ft above mean sea level, adjust-

 lent of 1912. Prior to Mar. 5, 1937, chain gage on highway bridge at same site and 

datum.

Average discharge. 34 years, 449 cfs.

Extremes.--Maximum discharge during year, 7,330 cfs Mar. 11 (gage height, 6.81 ft); mini-

 mumT35 cfs Sept. 13, 14 (gage height, 0.48 ft, backwater from weeds). '

1918-52: Maximum discharge, 41,100 cfs July 8, 1935 (gage height, 11.6 ft, from 

floodmarks), from rating curve extended above 11,000 cfs on basis of velocity-area 

and slope-area determinations of peak flow and by logarithmic plotting; minimum, 8 cfs 

Sept. 6, 7, 1934.

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

 weed's, which are fair. During each year a large part of flow from 45 sq mi of drainage 

area above Lake Lamoka Outlet on Mud Creek, a tributary above this station, is diverted 

into Keuka Lake for power development.

Revisions (water years). W 756: Drainage area. W 891: 1935.

Rating table, water year 1951-52, except periods of ice effect or 

backwater from weeds (gage height, in feet, and discharge, in 

cubic feet per second)

POTOMAC RIVER BASIN 411

Georges Creek at Franklin, Md.

Location.--Lat 39°29'38", long. 79°02'42", on right bank at Franklin, Allegany County, 

1-J- miles upstream from Westernport t..id mouth.

Drainage area. 72.4 sqmi.

Records available.--May 1905 to July 1906, October 1989 to September 1952. Published as 

"at Westernport" 1905-6.

Gage.--Water-stage recorder. Datum of gage is 958.96 ft above mean sea level (West 

Virginia Pulp & Paper Co. benchmark). May 4, 1905, to July 16, 1906, chain gage at 

bridge three-quarters of a mile downstream at different datum. Oct. 16, 1929, to 

Oct. 1, 1937, water-stage recorder at site 95 ft downstream at same datum.

Average discharge.--23 years (1929-52), 76.7 cfs.

Extremes.--Maximum discharge during year, 2,680 cfs Mar. 11 (gage height, 8.57 ft); minimum, 4.3 cfs Nov. 21.

1905-6, 1929-52: Maximum discharge, 8,500 cfs Mar. 17, 1936 (gage height, 9.6 ft, 

site then in use), from rating curve extended above 2,000 cfs on basis of slope-area 

determination of peak flow; minimum, 1.6 cfs Oct. 2, 4-8, 1930.

Remarks --Records good except those for periods of ice effect or doubtful or no gageheight record, which are fair. Records include about 0.5 cfs 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 Eckhart and Welsh Hill. Records include drainage from 

numerous active and abandoned coal mines.

cfs). Flood of Mar. 17, 1936, reached a stage of about 23.5 ft, from floodmarks (discharge, about 50,000 cfs).

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

good, and those for period of ice effect, which are fair. Some regulation at low flow 

by Stony River Reservoir 66 miles above station (see p. 406) 'and since December 1950, 

by Savage River Reservoir (see p. 409).

416 POTOMAC RIVER BASIN

North Branch Potomac River near Cumberland, Md.

Location. Lat 39°37'16", long. 78°46'24", on left bank at downstream side of Wileys Ford

Bridge, 2 miles south of Cumberland, Allegany County, and 2.1 miles downstream from Wills Creek.

Drainage area. 875 sq mi.

Records available. May 1929 to September 1952. 

Gage. Water-stage recorder. Datum of gage is 585.22 ft above mean sea level (Corps of

Engineers benchmark). Prior to June 18, 1929, chain gage at same site and datum. 

Average discharge.--23 years, 1,219 cfs (unadjusted). 

Extremes.--Maximum discharge during year, 20,700 cfs Mar. 11 (gage height, 16.69 ft); minimum, 70 cfs July 23, caused by gate operation at dam in Cumberland; minimum daily, 83 cfs Oct. 6.

1929-52: Maximum discharge, 88,200 cfs Mar. 17, 1936 (gage height, 29.1 ft), from

rating curve extended above 21,000 cfs on basis of slope-area determination of peak

flow; minimum (river only), 12 cfs Sept. 22, 1932 (gage height, 2.38 ft); minimum daily

(including flow in canal), 38 cfs Sept. 24, 1932.

Maximum stage known, 29.2 ft June 1, 1889 (discharge, about 89,000 cfs). Flood of

Mar. 29, 1924, reached a stage of 28.4 ft (discharge, about 82,000 cfs). 

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

which are good. Regulation by reservoir on Stony River, about 79 miles above station

(see p. 406), and, since December 1950, by reservoir on Savage River (see p. 409)- Small

amount of inflow from industrial wastes and sewage from City of Cumberland from water

diverted from Evitts Creek, mouth of which is below station.

1945-52: Maximum discharge, 600 cfs June 18, 1949 (gage height, 2.68 ft, site and 

datum then in use), from rating curve extended above 100 cfs by logarithmic plotting; 

minimum, 4.9 cfs Oct. 6-8, 1947.

Remarks. Records good. Big Spring, which emerges several places half a mile above gage, 

is the source of entire flow except during wet weather when surface drainage from 

about 1 sq mi enters the stream above gage. Flow from surface sources is included in 

the records but is relatively small except during heavy rains.

Potomac River at Hancock, Md.

Location. Lat 39°41'49", long. 78°10'39", on left bank 0.2 miles downstream from Little 

Tonoloway Creek, half a mile downstream from new highway bridge at Hancock, Washington 

County, and 1.1 miles upstream from Big Tonoloway Creek (formerly called Great 

Tonoloway Creek).

Drainage area. 4,073 sq mi.

Records available. October 1932 to September 1952.

Gage. Water-stage recorder. Datum of gage is 383.46 ft above mean sea level, adjustment 

of 1912. Oct. 1, 1932, to Aug. 27, 1934, chain gage and Aug. 28, 1934, to Jan. 5, 

1935, Mar. 18, 1936, to Jan. 20, 1937, wire-weight gage, on former highway bridge just 

upstream at same datum. Jan. 6, 1935, to Mar. 18, 1936, water-stage recorder at present 

site and datum.

Average discharge. 20 years, 4,117 cfs.

Extremes.--Maximum discharge during year, 58,600 cfs Apr. 29 (gage height, 21.89 ft); minimum, 219 cfs Oct. 9 (gage height, 2.36 ft).

1932-52: Maximum discharge, 340,000 cfs Mar. 18, 1936 (gage height, 47.6 ft), 

from rating curve extended above 120,000 cfs on basis of slope-area determination of 

peak flow; minimum observed, 180 cfs Oct. 4, 1932 (gage height. 2.01 ft).

Maximum stage known prior to 1932, about 40 ft in May 1889 (discharge, about 220,000 

cfs).

Remarks. Records excellent except those for periods of fragmentary, doubtful, or tapegage record, and those for October, which are good, and those for periods of ice effect 

or no gage-height record, which are fair. Slight regulation at low flow from powerplants upstream. Low flow affected slightly by Stony River Reservoir (see p. 406) 

and since December 1950 by Savage River Reservoir (see p. 409).

Revisions (water years). W 781: 1933(M). W 801: Drainage area.

458 POTOMAC RIVER BASIN

Potomac River at Point of Rocks, Md.

Location. Lat 39 0 16'25", long. 77°32'35", on left bank at downstream side of highway 

bridge at Point of Rocks, Frederick County, a third of a mile downstream from Catoctin Creek and 6 miles upstream from Monocacy River.

Drainage area. 9,651 sq mi.

Records available. February 1895 to September 1952.

gage. Water-stage recorder. Datum of gage is 200.54 ft above mean sea level, adjustment of 1912. Prior to Oct. 7, 1929, chain gage on downstream side of highway bridge 

at same datum.

Average discharge. 56 years (1896-1952), 9,462 cfs.

Extremes. Maximum discharge during year, 127,000 cfs Apr. 29 (gage height, 20.67 ft); minimum, 976 cfs Oct. 29 (gage height, 0.57 ft).

1895-1952: Maximum discharge, 480,000 cfs Mar. 19, 1936 (gage height, 41.03 ft), 

from rating curve extended above 300,000 efs on basis of adjustment of figure of peak 

flow at station near Washington for inflow and storage, and slope-area determination 

of peak flow; minimum, 540 cfs Sept. 10, 1914 (gage height, 0.38 ft).

Flood of June 2, 1889, reached a stage of 40.2 ft, from floodmarks (discharge, 

about 460,000 cfs, from rating curve extended as explained above).

Remarks. Records excellent except those for period of ice effect, which are good. Low

flow affected slightly since 1913 by Stony River Reservoir (see p. 406) and since 

. December 1950 by Savage River Reservoir (see p. 409).

Revisions (water years). W 192: 1895-1905.

476 POTOMAC RIVER BASIN

Northwest Branch Anacostia River near Hyattsville, Md.

Location (revised).--Lat 38°57'09", long. 76°58'00", on right bank at downstream side of 

Queens Chapel Road Bridge, 1 mile west of Hyattsville, Prince Georges County, and 0.8 

mile downstream from Sligo Branch.

Drainage area. 49.4 sq mi.

Records available.--July 1938 to September 1952.

Sage. Water-stage recorder. Datum of gage is 17.30 ft above mean sea level, adjustment of 

1912. Prior to Oct. 22, 1938, wire-weight gage at same site and datum. Oct. 22, 1938, 

to Sept. 17, 1951, water-stage recorder at same site and datum. Sept. 17, 1951, to 

Aug. 29, 1952, staff gage and crest-stage indicator; gage read twice daily.

Average discharge. 14 years, 37.2 cfs (unadjusted).

Extremes. Maximum discharge during year, 3,360 cfs Sept. 1 (gage height, 11.4 ft, from 

floodmark); minimum observed, 3.3 cfs Oct. 6, 7.

1938-52: Maximum discharge, that of Sept. 1, 1952; minimum, 0.8 cfs Oct. 3, 7, 1941, 

Aug. 26, 1943.

Maximum stage known, about 13.5 ft in August 1933.

Remarks. Records fair prior to Aug. 29 except those for period of no gage-height record, 

which are poor, good thereafter. Low flow regulated by storage and diversion at Burnt 

Mills Dam, by filtration plant 7 miles above station, and by inflow pumped from Patuxent 

River basin as required for water supply for Washington Suburban Sanitary District.

Revisions (water years). W 971: 1942(M).
