SCOPE OP 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, 1955. 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 13,250 gaging stations in the 48 States and at many others in the Territories of Alaska and Hawaii. On September 30, 1955, the Geological Survey and cooperating 

organizations were maintaining 6,860 gaging stations, including those in Alaska and Hawaii. 

Discharge measurements only were made at many other points in the 1955 water year, most of 

which are published at the end of each report. The name of each stream measured at points 

other than gaging stations is not listed in the index to this report. Only the major river 

basins in which measurements were made are listed under the item "Discharge measurements" 

in the index.

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records of discharge prior to publication, and other unpublished data concerning the 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 feet 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 stagedischarge 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, 1955, PART 1-B

WSP is used as an abbreviation for "Water-Supply Paper" in references to previously 

published reports.

DOWNSTREAM ORDER OF 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 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 

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

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.

6 SURFACE WATER SUPPLY, 1955, PART 1-B

At some gaging stations the stage-discharge relation is affected 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 In 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 

daily 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. Records are published for the water year which begins on October 1 

and ends on September 30. A calendar for the water year 1955 is shown on page IV for 

the purpose of finding the day of the week for any date.

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 "Records available" are given the 

periods for which there are published records generally equivalent to those at the present 

site. 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, locations, and 

datums of previous gages used during the period of records available. 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). In the first paragraph, the data given are for 

the complete current water year unless otherwise specified. In the second paragraph, the 

data given are for the periods of record within the calendar year dates in the heading 

(not necessarily those for the complete years indicated by the heading dates). Reliable 

information concerning major floods that have occurred outside the period of record are 

given in the third or last paragraph under "Extremes." 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
EXPLANATION OP DATA 7

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."

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 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. Skeleton rating tables are generally 

not published for stations on canals.

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 figures for the maximum day and the minimum day 

for each month are underlined. If the figure 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 figures; 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
8 SURFACE WATER SUPPLY, 1955, PART 1-B

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"). Figures for cubic feet per second per 

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 figures 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
PUBLICATIONS

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

comparison with the observed discharge.

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. The 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. 

Discharge measurements at many points other than regular gaging stations have been made 

each year and are published 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 table on page 12 lists reports of this type for 

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

County, N. Y.

HYDROLOGIC CONDITIONS

In the area covered by this report, streamflow varied widely during the 1955 water 

year. During October, April, May, and July streamflow was deficient over a large part of 

the area. Record-low flows for the month occurred at the gaging station on South Branch 

Raritan River at High Bridge, N. J., in April, June, and July; at Great Egg Harbor at 

Folsom, N. J., in May; at Seneca Creek near Dawsonville, Md., and Susquehanna River at 

Harrisburg, Pa., in July. The Harrisburg record extends back to 1890. Floods occurred in 

the upper reaches of the Potoraac River in October, exceeded only by those of March 1924. 

Runoff of Potomac River at Paw Paw, W. Va., was record-high for the month in November, 

March, and August. Floods in August resulting from passage of two tropical hurricanes 

were record-breaking over most of the area; at some gaging stations the peak discharges 

were 2 to 3 times previous maxima in 30 to 50 years of record. A preliminary report on 

these floods has been published as Circular 377; a comprehensive report is being prepared 

for publication as WSP 1420. For a comparison of the monthly and yearly mean discharge 

with the medians for the period 1921-45, for three key gaging stations in the area covered

22 STREAMS ON LONG ISLAND

Cold Spring Brook at Cold Spring Harbor, N. Y.

Location. Lat 40°51'25", long 73°27'50", on left bank 270 ft upstream from State Highway 

25A, at Cold Spring Harbor State Fish Hatchery, Nassau County, and 1 mile southwest of 

village of Cold Spring Harbor, Suffolk County.

Drainage area. About 7.3 sq mi.

Records available. July 1950 to September 1955.

Gage. --Water-stage recorder and concrete control. Datum of gage is 5.38 ft above mean 

sea level, datum of 1929.

Average discharge. 5 years, 2.18 cfs (unadjusted).

Extremes . Maximum discharge during year, 46 cfs Aug. 12 (gage height, 0.994 ft, backwater from aquatic vegetation); maximum gage height, 1.833 ft Apr. 24 (backwater from 

high tide); minimum discharge, 0.67 cfs Jan. 24 (gage height, 0.124 ft).

1950-55: Maximum discharge, 108 cfs Sept. 11, 1954 (gage height, 1.332 ft, backwater from aquatic vegetation); maximum gage height, 5.342 ft Aug. 31, 1954 (backwater 

from high tide); minimum discharge, 0.39 cfs Feb. 9., 1951 (gage height, 0.086 ft), 

result of ice action.

Remarks . Records good except those for periods of doubtful gage -height record or backwater from debris, aquatic vegetation, or high tide, which are fair. Flow 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. See page 534 for results of discharge measurements of Long 

Island streams at sites other than regular gaging stations.

STREAMS ON LONG ISLAND 23

Nlssequogue River near Smlthtown, N. Y.

Location. Lat 40°50"55", long 73°13"25", on left bank half a mile downstream from Blydenburgh Pond and 1 mile southwest of Smlthtown, Suffolk County.

Drainage area.--About 27 sq ml.

Records available. October 1943 to September 1955.

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

level, datum of 1929.

Average discharge. 12 years, 40.65 cfs.

Extremes. Maximum discharge during year, 138 cfs Aug. 12 (gage height, 1.222 ft, backwater from aquatic vegetation); minimum, 29.5 cfs Sept. 23 (gage height, 0.587 ft); 

minimum dally, 30.5 cfs Sept. 21.

1943-55: 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 by logarithmic plotting; minimum, 18.6 cfs Feb. 9, 1951 (gage height, 0.460 ft); minimum 

dally, 20.0 cfs Oct. 6, 1947.

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

or debris, 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. See page 534 for results of discharge measurements of Long Island streams at 

sites other than regular gaging stations.

from outlet of Sweezy Pond.

Drainage area. About 75 sq mi.

Records available. June 1942 to September 1955.

Gage. Water-stage recorder and concrete control. Datum of gage is 6.54 ft above mean sea 

Tevel, datum of 1929.

Average discharge. 13 years, 31.84 cfs.

Extremes. Maximum discharge during year, 81 cfs Aug. 12 (gage height, 0.762 ft, backwater 

 from aquatic vegetation); maximum gage height, 0.768 ft Jan. 7 (backwater from debris): 

minimum discharge, 2.12 cfs (result of ice action) Dec. 7 (gage height, 0.131 ft): minimum daily, 16.5 cfs July 15.

1942-55: Maximum discharge, 140 cfs Apr. 14, 1953 (gage height, 0.966 ft); minimum, 

1.52 cfs Jan. 8, 1952 (gage height, 0.108 ft), result of freezeup; minimum daily, 

3.67 cfs Aug. 2, 1944.

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

which are good, and those for periods of backwater from debris, which are fair. Flow 

regulated by ponds 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 le-vels are collected, some of which are published in water-supply 

papers. See page 534 for results of discharge measurements of Long Island streams at 

sites other than regular gaging stations.

26 STREAMS ON LONG ISLAND

Swan River at East Patchogue, N. Y.

Location. Lat 40°46'00", long 72°59'35", on left bank 94 ft downstream from Montauk Highway in East Patchogue, Suffolk County, 200 ft downstream from outlet of Swan Lake, 

ITT miles upstream from mouth, and it miles east of Patchogue.

Drainage area.--About 8.8 sq mi.

Records available. October 1946 to September 1955.

Gage. Water-stage recorder and concrete control. Datum of gage is 2.84 ft above mean

sea level, datum of 1929. 

Average discharge. 9 years, 12.41 cfs.

Extremes. Maximum discharge during year, 47 cfs Aug. 12 (gage height, 1.521 ft, backwater from debris below control), from rating curve extended above 18 cfs by logarithmic plotting; minimum, 0.27 cfs Mar. 31 (gage height, 0.078 ft); minimum daily, 

9.4 cfs July 9.

1946-55: Maximum discharge, that of Aug. 12, 1955; maximum gage height, 1.801 ft 

Sept. 11, 1954 (backwater from debris below control); minimum discharge, 0.1 cfs Feb. 6, 

1947jgage height, 0.050 ft); minimum daily, 6.1 cfs Oct. 18, 1953.

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

vegetation, which are good, and those for periods of no gage-height record or backwater from debris below control, which are fair. Plow regulated infrequently at outlet of Swan Lake. This station is operated in connection with an inventory of water 

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

page 534 for results of discharge measurements of Long Island streams at sites other 

than regular gaging stations.

Rating tables, water year 1954-55, except periods of backwater from aquatic 

vegetation or debris on or below control (gage height, in feet, and 

discharge, in cubic feet per second)

28 STREAMS ON LONG ISLAND

Connetquot River near Oakdale, N. Y.

Location. Lat 40°44'50", long 73 0 09'00", on left bank just downstream from highway bridge, 

1 mile west of Oakdale, Suffolk County, and 2 miles north of village of Great River.

Drainage area. About 24 sq mi.

Records available. October 1943 to September 1955.

Gage. Water-stage recorder and wooden stoplog control. Datum of gage is 1.56 ft above 

mean sea level, datum of 1929. Supplementary water-stage recorder with concrete control on left bank of secondary channel a quarter of a mile northeast of base gage at 

datum 5.74 ft above mean sea level, datum of 1929.

Average discharge. 12 years, 38.95 cfs

Extremes. Maximum daily discharge during year, 123 cfs Aug. 13; minimum daily, 27.8 cfs 

Aug. 2, 3.

1943-55: Maximum daily discharge, that of Aug. 13, 1955; minimum daily, 23.4 cfs 

Sept. 10, 1944.

Remarks. Records good except those for periods of no gage-height record, shifting control, 

or backwater from debris or high tide, which are fair. Plow at both gages regulated occasionally by cleaning operations at outlets of ponds above station. Discharge figures 

given are those of combined flows in main and secondary channels. This station is operated in connection with an inventory of 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. See page 534 for results of discharge measurement si of 

Long Island streams at sites other than regular gaging stations.

1945-55: Maximum discharge, that of Aug. 12, 1955; minimum, 1.49 cfs Nov. 10, 1949 

(gage height, 0.215 ft), result of temporary obstruction at culvert upstream.

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

debris, which are fair. 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. 

See page 534 for results of discharge measurements of Long Island streams at sites 

other than regular gaging stations.

STREAMS ON LONG ISLAND 31

Sampawams Creek at Babylon, N. Y.

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

Bridge in Babylon, Suffolk County, 180 ft downstream from Long Island Railroad aril 

3,000 ft upstream from mouth.

Drainage area.--About 23 sq mi.

Records available. October 1944 to September 1955.

Qage.--Water-stage recorder and concrete control. Datum of gage is 6.70 ft above mean 

sea level, datum of 1929.

Average discharge.--11 years, 9.18 cfs.

Extremes. Maximum discharge during year, 106 cfs Aug. 12 (gage height, 1.854 ft, backwater from aquatic vegetation and weeds below control); minimum, 2.65 cfs Aug. 3 (gage 

height, 0.232 ft, backwater from aquatic vegetation); minimum daily, 3.35 cfs Aug. 3. 

1944-55: Maximum discharge, that of Aug. 12, 1955; minimum, that of Aug. 3, 1955; 

minimum daily, that of Aug. 3, 1955.

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

from aquatic vegetation or weeds below control, which are fair. Plow regulated 

slightly by pumping operations at railroad and occasionally by ponds above station. 

Prior to November 1950, slight diurnal fluctuation caused by power operations. 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. See page 534 for results of discharge measurements of Long Island streams at sites other than regular gaging stations.

STREAMS ON LONG ISLAND 33

Santapogue River at Lindenhurst, N. Y.

Location.--Lat 40°41'30" (corrected), long 73°21'20", on left bank just upstream from 

East Hoffman Avenue Bridge, 1 mile east of Long Island Railroad station in Lindenhurst, 

Suffolk County, and if miles upstream from mouth.

Drainage area. About 7 sq mi.

Records available. June 1947 to September 1955.

Gage. Water-stage recorder and concrete control. Datum of gage is 9.71 ft above mean 

sea level, datum of 1929.

Average discharge. 8 years, 5.26 cfs.

Extremes. Maximum discharge during year, 36.1 cfs Aug. 13 (gage height, 0.916 ft); minimum, 0.28 cfs Aug. 6 (gage height, 0.120 ft).

1947-55: Maximum discharge, 42.2 cfs Sept. 11, 1954 (gage height, 0.911 ft); maximum gage height, 1.152 ft July 14, 1948; minimum discharge, 0.18 cfs July 31, Aug. 1, 

1954 (gage height, 0.103 ft).

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

or backwater from aquatic vegetation or debris, which are good. 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. See page 534 for results of discharge measurements of Long Island streams at sites other than regular gaging stations.

Park, and 3,000 ft upstream from Clark Avenue Bridge and head of Massapequa Pond of 

Brooklyn water-supply system.

Drainage area. About 38 sq mi.

Records available. June to October 1903 (in Professional Paper 44), December 1936 to

September 1955. Published as Massatayun Creek at Massapequa December 1936 to September

Gage. Water-stage recorder and concrete control. Datum of gage is 19.31 ft above mean 

sea level, adjustment of 1912. Prior to October 1903, staff gage at different datum.

Average discharge. 18 years (1937-55), 11.93 cfs.

Extremes. Maximum discharge during year, 180 cfs Aug. 12 (gage height, 1.833 ft),

includes 9 cfs flow bypassing gage; minimum, 3.18 cfs Aug. 6 (gage height, 0.347 ft).

1903, 1936-55: Maximum discharge, that of Aug. 12, 1955; minimum, 2.66 cfs Aug. 1, 

1954 (gage height, 0.322 ft).

Remarks.--Records good except those for periods of fragmentary, or doubtful or no gageHeight record, which are fair. 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. See page 534 for results of discharge measurements of Long Island streams at 

sites other than regular gaging stations.

STREAMS ON LONG ISLAND db

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 1955.

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. 18 years (1937-55), 9.66 cfs.

Extremes. Maximum discharge during year, 168 cfs Aug. 12 (gage height, 1.875 ft); minimum, 1.57 cfs July 22 (gage height, 0.272 ft); minimum daily, 4.9 cfs Aug. 6.

1903, 1937-55: Maximum discharge, 340 cfs June 1, 1952 (adjusted to include flow 

bypassing station); maximum gage height, 2.566 ft June 1, 1952; minimum discharge, 

1.26 cfs Dec. 11, 1941 (gage height, 0.261 ft); minimum dally, 1.84 cfs Sept. 12, 1943.

Remarks. Records excellent except those for periods of backwater from debris, fragmentary, doubtful or no gage-height record, indeterminate stage-discharge relation, or 

diversion around station, which are fair. Flow at all stages regulated intermittently 

at outlet of Wantagh Reservoir, 1 mile above station, and prior to November 1953 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 watersupply papers. Seepage 534 for results of discharge measurements of Long Island streams 

at sites other than regular gaging stations.

36 STREAMS ON LONG ISLAND

East Meadow Brook at Freeport, N. Y.

Location. Lat 40°39'55", long 73°34'10", on left bank in Freeport, Nassau County, 50 ft 

upstream from bridge on Hempstead-Babylon turnpike and 300 ft west of East Meadow 

Brook Parkway.

Drainage area. About 31 sq mi.

Records available. October 1851 to December 1852, June to October 1883, September and 

October 1885, June to October 1903, January 1937 to September 1955. Prior to 1903, 

records fragmentary, published in Professional Paper 44.

Qage. Water-stage recorder and concrete control. Datum of gage is 10.92 ft above mean 

sea level, adjustment of 1912. Prior to October 1885, determinations of flow by various methods at different site and datum. June to October 1903, weir in swamp at head 

of Brooklyn waterworks supply pond.

Average discharge. 18 years (1937-55), 17.27 cfs.

Extremes.--Maximum discharge during year, 355 cfs Aug. 13 (gage height, 3.658 ft, backwater from Freeport Pond); minimum, 5.16 cfs July 3 (gage height, 0.281 ft).

1903, 1937-55: Maximum discharge, that of Aug. 13, 1955; minimum, 5.04 cfs (caused 

by ice Jam above station) Feb. 21, 1942; minimum gage height, that of July 3, 1955. 

An average discharge of 6.54 cfs was recorded for period Sept. 19 to Oct. 2, 1885.

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

periods of backwater from Freeport Pond, which are fair. 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. See page 534 for results of discharge measurements 

of Long Island streams at sites other than regular gaging stations.

Drainage area. About 10 sq mi.

Records available.--1851-52. 1856-57, 1885, and 1894 (fragmentary in Professional Paper 44), 

December 1936 to September 1955.

Gage. Wafer-stage recorder and concrete control with V-notch weir. Datum of gage is 

~sF.42 ft above mean sea level, adjustment of 1912. Prior to 1894, determinations of flow 

by various methods, at different sites and datums.

Average discharge.--18 years (1937-55), 5.76 cfs.

Extremes. Maximum discharge during year, 191 cfs Aug. 12 (gage height, 2,755 ft); minimum, 0.20 cfs Mar. 10 (gage height, 0.273 ft); minimum daily, 0.20 cfs Mar. 10.

1936-55: Maximum discharge, that of Aug. 12, 1955; minimum, 0,05 cfs Feb. 15, 1940 

(gage height, 0.196 ft); minimum daily, 0.12 cfs Apr. 2, 1940.

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

debris, which are fair. Flow occasionally regulated by Pines Pond. Indeterminate diversion from Pines Pond for emergency municipal water supply for New York City August 

1953 to September 1954. This station is operated in connection with an inventory of 

water resources on Long Island. In addition to records of streamflow, records of

§ round-water levels are collected, some of which are published in water supply papers^ 

ee page 534 for results of discharge measurements of Long Island streams at sites other 

than regular gaging stations.

Extremes.--Maximum discharge during year, 174 cfs Aug. 12 (gage height, 5.134 ft, backwater from aquatic vegetation), from floodmark on hook gage; minimum, 0.78 cfs Aug. 2 

(gage height, 0.163 ft, backwater from aquatic vegetation).

1954-55: Maximum discharge, that of Aug. 12, 1955; minimum, that of Aug. 2, 1955.

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

vegetation, which are good, and those for periods of doubtful gage-height record, or 

backwater from weeds, debris, or construction below control, which are fair. Flow regulated occasionally by cleaning operations at outlet of Valley Stream Pond 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. See page 534 for results of 

discharge measurements of Long Island streams at sites other than regular gaging stations .

HUDSON RIVER BASIN 43 

Indian River near Indian Lake, N. Y.

Location. Lat 43°45'30", long 74 "16'05", on right bank three-quarters of a mile downstream from Indian Lake Dam, 1 mile upstream from Big Brook, and 2 miles south of 

village of Indian Lake, Hamilton County.

Drainage area.--132 sq mi.

Records available.--July 1912 to June 1914, June 1915 to September 1955.

gage.--Water-stage recorder. Datum of gage is 1,604.27 ft above mean sea level, adjustment of 1912. Prior to Aug. 30, 1916, staff gage at same site and datum.

Average discharge.--40 years (1912-13, 1916-55), 293 ofs (unadjusted).

Extremes.--Maximum discharge during year, 1,010 cfs June 2 (gage height, 4 00 ft, from 

reconstructed gage-height graph); minimum daily, 33 cfs Mar. 14; minimum gage height, 

0.79 ft Mar. 14.

1912-14, 1915-55: Maximum discharge, 3,460 cfs Mar. 28, 1913 (gage height, 7.8 ft); 

minimum, less than 1 cfs frequently when entire flow of river is being stored in 

Indian Lake Reservoir.

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

record, which are good. Flow almost completely regulated by Indian Lake Reservoir 

(see preceding page).

Drainage area.--1,044 sq mi.

Records available.--January 1930 to September 1955. 

Gage.--Water-stage recorder. Datum of gage is at mean sea level, adjustment of 1912.

Prior to Apr. 23, 1930, staff gage at same datum in outlet channel 800 ft downstream. 

Extremes.--Maximum elevation during year 768.51 ft Apr. 28 (contents, 34,850,000,000

 cu ft); minimum, 743.00 ft Feb. 28 (contents, 10,040,000.000 cu ft).

1930-55: Maximum elevation, 769.43 ft Apr. 19, 1954 (contents, 35,900,000,000

cu ft); minimum since first filling, 729.55 ft Mar. 30, 1940 (contents, 2,100,000,000

cu ft). 

Remarks.--Reservoir is formed by earth and concrete dam; storage began in March 1930; dam

 completed in 1930. Usable capacity for stream regulation, 29,670,000,000 cu ft between 

elevations 735.0 and 768.0 ft. Between elevations 768.0 and 771.0 ft (spillway crest) 

an additional 3,450,000,000 cu ft is available exclusively for flood storage. Elevation of inverts of three Dow valves is 699.0 ft. Capacity of 4,600,000,000 cu ft 

below elevation 735.0 ft is considered dead storage, except for extraordinary emerf

encies or for necessary inspection of structures. Purpose of reservoir is to provide 

lood control and low-water stream regulation for sanitary improvement, navigation, 

and power, as required by the public welfare, including public health and safety. Area 

of water surface of reservoir filled to capacity (elevation, 771.0 ft) is 41.7 sq mi. 

Cooperation.--Records furnished by Board of Hudson River Regulation District.

1929. Prior to March 1922, chain gage and July 24, 1923, to July 18, 1936, water-stage 

recorder, at site a quarter of a mile upstream at different datum.

Average discharge. 43 years (1910-21, 1923-55), 920 cfs.

Extremes. Maximum discharge during year, 7,640 cfs Feb. 23 (gage height, 9.41 ft); maximum gage height, 13.19 ft Feb. 7 (backwater from ice); minimum discharge, 77 cfs 

Aug. 10, 11 (gage height, 3.19 ft); minimum daily, 112 cfs Aug. 7.

1910-22, 1923-55: Maximum discharge, 55,400 cfs Dec. 31, 1948 (gage height, 

21.15 ft» from high-water mark in gage house), from rating curve extended above 13,000 

cfs on basis of peak flow over downstream dams and contracted-opening determinations at 

gage heights 17.8 and 21.15 ft; minimum, 24 cfs Sept. 14, 1913; minimum daily, 30 cfs 

Sept. 14, 1913.

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

record, which are fair. Diurnal fluctuation at medium and low flow caused by powerplants above station.

Sacandaga Reservoir (see p. 51) and Indian Lake Reservoir (see p. 42). No adjustment 

is made for water diverted through Glens Palls feeder into Champlain Canal. During 

canal navigation season, water is diverted into St. Lawrence River basin through Glens 

Palls feeder, Bond Creek, and Champlain Canal and occasionally may receive water from 

that basin through level of Champlain Canal at Dunham Basin (see p. 54,55). No 

adjustment made for these diversions.

Records available.--October 1927 to September 1955 in reports of Geological Survey. December 1919 to September 1926 (prior to July 1921, gage heights only) in reports of 

State engineer and surveyor.

Gage. Water-stage recorder. Datum of gage is 474.00 ft above mean sea level (Barge 

iTanal datum). Prior to Jan. 24, 1937, staff gage at site 200 ft downstream at same 

datum.

Average discharge. 34 years (1921-55), 398 cfs (unadjusted).

Extremes.--Maximum discharge during year, 1,850 cfs Apr. 15 (gage height, 5.33 ft); minimum, 119 cfs Feb. 10, 11 (gage height, 1.50 ft); minimum daily, 121 cfs Feb. 11-14.

1927-55: Maximum discharge, 8,560 cfs Oct. 2. 1945 (gage height, 11.18 ft); minimum, 30 cfs Sept. 27, 1945 (gage height, 0.65 ft); minimum daily, 45 cfs (estimated) 

Jan. 17, 1931.

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

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

Reservoir above station. Flow completely regulated by Delta Reservoir, (usable capacity, 2,800,000,000 cu ft). Small quantity of water diverted from Delta Reservoir for 

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

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

Remarks.--Records excellent. Since 1916, flow completely regulated by Hinckley Reservoir

 except for periods of spilling (usable capacity, 3,320,000,000 cu ft). Comparatively 

small diversion from Hinckley Reservoir for Utica water supply.

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 1955 in reports of Geological Survey. January 1910 to December 1911 and January 1914 to September 1920 in reports of State engineer and surveyor.

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

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

different datum.

Average discharge.--35 years (1920-55), 1,337 cfs.

Extremes.--Maximum discharge during year, 11,700 cfs Mar. 11 (gage height, 6.43 ft); minimum, 127 cfs Aug. 26 (gage height, 1.48 ft); minimum daily, 316 cfs Aug. 24, 28.

1920-55: 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, 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.

72 HUDSON RIVER BASIN

Mohawk River near Little Falls, N. Y.

Location.--Lat 43°00'50", long 74°46'40", on left bank 1,800 ft downstream from Rooky Rift

 Dam, 2 miles upstream from East Canada Creek, and 4? miles southeast of city of Little

Palls, Herkimer County. 

Drainage area.--1,548 sq mi. 

Records available.--February to April 1901 and October 1927 to September 1955 in reports of

 Geological Survey. November 1923 to September 1927 (gage heights and discharge measurements only) in files of State Department of Public Works. 

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

 datum). February to April 1901, staff gage at site 1,800 ft upstream at different

datum.

Average discharge.--28 years (1927-55), 2,793 cfs. 

Extremes.--Maximum discharge during year (river channel only), 20,900 cfs Mar. 11 (gage

 Height, 16.07 ft); minimum (river channel only), 486 cfs Sept. 8 (gage height, 4.34 ft);

minimum daily (including canal), 626 cfs Sept. 10.

1927-55: Maximum discharge (river channel only), 25,300 cfs 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 fragmentary or no

 gage-height record, which are fair. Records of daily discharge include diversion at 

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

During canal navigation season, water is received from Black River basin through Black 

River Canal (flowing south) and Lansing Kill, and 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 powerplants and locks and dams on Barge Canal. Appreciable 

regulation by Delta and Hinckley Reservoirs (combined usable capacity, 6,120,000,000 

cu ft).

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

HUDSON RIVER BASIN 77

Mohawk River at Cohoes, N. Y.

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

Mohawk Power Corp. in Cohoes, Albany County, if miles upstream from mouth.

Drainage area. 3,456 sq mi.

Records available. July 1925 to September 1955.

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

1929. Prior to Oct. 19, 1925, powerplant gage.

Average discharge.--30 years, 5,693 cfs.

Extremes. Maximum discharge during year, 51,500 cfs Mar. 12 (gage height, 17.86 ft); 

minimum, 39 cfs Sept. 18 (gage height, 3.32 ft); minimum daily, 79 cfs Aug. 7.

1925-55: 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 good. Records include small diversion just above gage for Cohoes water 

supply but do not include diversion through lock 6 at Crescent Dam (published herewith) 

for operation of Barge Canal. During canal navigation season, water is received from 

Black River basin through Black River Canal (flowing south) and Lansing Kill, and 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. Records of chemical analyses, 

water temperatures, and suspended sediment loads for the water year 1955 are given in 

WSP 1400.

HUDSON RIVER BASIN 79

Hudson River at Green Island, N. Y.

Location.--Lat 42°45'10", long 73°41'20", on right bank at Green Island, Albany County, 

just upstream from Troy lock and dam, half a mile downstream from 5th branch Mohawk 

River.

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

Records available. February 1946 to September 1955.

Gage.--Water-stage recorder. Datum of gage is 0.31 ft below mean sea level, datum of 1929 

[Corps of Engineers benchmark). Since July 1, 1946, auxiliary water-stage recorder on 

bypass channel at datum 10.59 ft higher.

Average discharge. 9 years, 14,250 cfs (including flow through bypass channel).

Extremes (main channel). Maximum discharge during year, 66,500 cfs Mar. 12; maximum gage 

height, 20.83 ft Mar. 12; minimum daily discharge, 2,070 cfs Sept. 5; minimum gage 

height, 14.33 ft July 5.

1946-55: Maximum discharge, 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. 1, 1949; 

minimum daily, 1,270 cfs Sept. 5, 1949; minimum gage height, 13.92 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 of 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 in 1913 was about 3.3 ft higher than flood in 1936, from information by Corps of 

Engineers.

Remarks. Records good except those for periods of shifting control, which are fair. 

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

Record of flow in bypass channel, which enters Hudson River l| miles downstream, is 

shown separately. Appreciable regulation by Sacandaga Reservoir (see p. 51), Indian 

Lake Reservoir (see p. 42), 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 city of New York (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 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, Bond Creek, (see p. 54,55) 

and Champlain Canal and occasionally may be received from that basin through summit 

level of Champlain Canal at Dunham Basin.

Cooperatioa. Powerplant records furnished by Ford Motor Co. in connection with a Federal 

Power Commission project.

Discharge, in cubic feet per second, water year October 1954 to September 1955

Average discharge.--16 years (1939-55), 39.2 cfs.

Extremes.--Maximum discharge during year, 3,800 cfs Aug. 18 (gage height, 4.68 ft), from 

rating curve extended above 1,300 cfs on basis of slope-area determination of peak flow; 

minimum, 2.9 cfs July 31; minimum gage height, 0.745 ft Sept. 22, 23.

1938-55: Maximum discharge, 3,800 cfs Nov. 25, 1950, computed on basis of peak flow 

of Chestnut Creek above Red Brook and slope-area determination of peak flow of Red 

Brook, and Aug. 18, 1955; maximum gage height, that of Aug. 18, 1955; minimum discharge, 

2.0 cfs Sept. 12, 1949; minimum gage height, 0.66 ft Feb. 7, 1939.

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

doubtful gage-height record, shifting control, or those for periods of twice-daily 

staff-gage readings, which are fair. Slight seasonal regulation caused by Beaverdam 

Pond on Red Brook.

Rating tables, water year 1954-55, except periods of loe effect, backwater from debris, 

or shifting control (gage height, In feet, and discharge, In cubic feet per second)

Records available.--October 1931 to September 1955 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 1955 (monthly discharges) In reports 

of Board of Water Supply, City of New York.

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

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

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

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

Average discharge. 5 yrs (1950-55), 57.3 cfs.

Extremes. Maximum discharge during year, 2,360 cfs Aug. 19 (gage height, 5.76 ft); mlni-

 mum, 1.3 cfs Oct. 14, 15 (gage height, 0.095 ft).

1906-55: Maximum discharge, 26,700 cfs Aug. 26, 1928 (slope-area determination by 

Board of Water Supply, City of New York); 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, backwater from debris, no 

gage-height record, or those below 2 cfs, which are fair. Flow regulated by Rondout 

Reservoir since October 1950. Subsequent to May 1951, entire flow above Merrlman Dam 

(drainage area, 94.4 sq mi), except for small releases, and during periods of spilling, 

diverted from Rondout Reservoir for water supply of city of New York.

Rondout Creek at Rosendale, N. Y.

Location. 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 1955 in reports of Geological Survey. January 1914 to January 1919 

in reports of State engineer and surveyor. 

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

929. Prior to January 1919, chain gage on highway bridge 150 ft downstream at datum 

4.0 ft lower,

Average discharge. 5 years (1950-55), 689 cfs.

Extremes. Maximum discharge during year, 30,900 cfs Aug. 19 (gage height, 23.93 ft, from 

floodmark in gage shelter), from rating curve extended above 15,000 cfs on basis of 

contracted-opening determination of peak flow; minimum, 4.9 cfs Aug. 1 (gage height, 

1.22 ft); minimum daily, 28 cfs Aug. 10.

1901-3, 1906-19, 1926-55: Maximum discharge, that of Aug. 19, 1955; minimum, 

4.1 cfs Aug. 19, 1954; minimum gage height, that of Aug. 1, 1955; minimum daily discharge, 8.5 cfs Sept. 30, 1948.

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

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

station. Some regulation by Rondout Reservoir since October 1950. Subsequent to May 

1951, entire flow above Merrlman Dam (drainage area, 94.4 sq mi), except for small releases and during periods of spilling, diverted from Rondout Reservoir, for municipal 

supply of city of New York.

106 PASSAIC RIVER BASIN

Rockaway River above reservoir, at Boonton, N. J.

Location. Lat 40°54'06", long 74°24'40", on right bank at Morris Avenue, Boonton, Morris 

County, 1.8 miles upstream from Boonton Reservoir Dam.

Drainage area. 116 sq mi.

Records available. October 1937 to September 1955.

gage. Water-stage recorder and concrete control. Datum of gage is 364.47 ft above mean 

sea level (New Jersey Geological Survey benchmark).

Average discharge. 17 years (1938-55), 227 cfs (unadjusted).

Extremes. Maximum discharge during year, 2,190 cfs Aug. 19 (gage height, 5.43 ft); minimum 

daily, 15 cfs Aug. 5.

1937-55: Maximum discharge, 3,250 cfs June 2, 1952 (gage height, 6.62 ft), from 

rating curve extended above 2,400 cfs; minimum, 1.5 cfs Mar. 1, 1938 (gage height, 

1.26 ft).

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

which are fair. Town of Boonton diverts water for municipal supply partly from Stony 

Brook Reservoir (capacity, 75,000,000 gal) and partly by pumping from wells in vicinity 

of Boonton. Most of this diversion is returned to Rockaway River 600 ft below gaging 

station on Rockaway River below reservoir, at Boonton as sewage effluent and is included 

in the records for that station. Flow regulated by Splitrock Reservoir 14| miles above 

station (see p. 124).

Cooperation. Gage-height record collected in cooperation with Jersey City.

Rating table, water year 1954-55, except period of ice effect (gage 

height, in feet, and discharge, in cubic feet per second)

Rockaway River below reservoir, at Boonton, N. J.

Location. Lat 40°53'47", long 74°23'36", on right bank 2,000 ft downstream from dam of 

Boonton Reservoir, Boonton, Morris County.

Drainage area. 119 sq mi.

Records available. March 1903 to February 1904, January 1906 to September 1955. Published as "near Boonton" 1903-4 and as "at Boonton" 1906-7.

. Water-stage recorder. Concrete control since Nov. 5, 1936. Datum of gage is 

95.68 ft above mean sea level (New Jersey Geological Survey benchmark). Mar. 15, 1903, 

to Feb. 2, 1904, staff gage at site 2,000 ft downstream at different datum. Jan. 1, 

1906, to Mar. 3, 1918, reference-point gage on Boonton Dam 2,000 ft upstream at datum 

109.57 ft higher than present datum.

Average discharge. 42 years (1913-55), 133 cfs (adjusted for sewage effluent).

Extremes. Maximum discharge during year, 1,870 cfs Aug. 21 (gage height, 6.03 ft); minimum daily, 0.3 cfs Nov. 12-15, 17.

flow for many days.

Remarks.--Records excellent except those below 10 cfs, which are good, and those for

period of no gage-height record, which are fair. Figures of daily discharge represent 

flow over control only. Sewage effluent enters river about 600 ft below station. Flow 

regulated by Boonton Reservoir 2,000 ft above station, and by Splitrock Reservoir 

16J miles above station (see p. 124). Water diverted from Boonton Reservoir for municipal supply of Jersey City (see p. 124).

Cooperation. Gage-height records for station and record of sewage-disposal plant effluent 

furnished by Jersey City.

River for municipal supply.

North Jersey District Water Supply Commission diverts water for municipal supply from 

Wanaque Reservoir on Wanaque River. In addition to water from Wanaque River, the Commission stores water diverted into Wanaque Reservoir from Post Brook near Wanaque and Ramapo 

River by pumping from Hampton Lakes. Figures of diversion from Wanaque Reservoir given 

herein show total diversion from Passaic River basin by North Jersey District Water Supply 

Commission. *

The Passaic Valley Water Commission diverts water from Passaic River above Seattle's 

Dam at Little Falls for municipal supply.

ELIZABETH RIVER BASIN 

Elizabeth River at Elizabeth, N. J.

127

Location. Lat 40°40'03", long 74°13'09", on left bank 85 ft upstream from Westfield 

Avenue Bridge in Elizabeth, Union County, and 3^ miles upstream from mouth.

Drainage area. 18.0 sq mi.

Records available.--October 1921 to September 1955.

Gage.--Water-stage recorder and concrete control. Datum of gage is 5.23 ft above mean sea 

level, datum of 1929. Prior to Oct. 1, 1922, hook gage at same site at datum 4.14 ft 

higher and Oct. 1, 1922, to May 18, 1923, at present datum.

Average discharge. 34 years, 23.0 cfs (unadjusted).

Extremes.--Maximum discharge during year, 2,440 cfs Aug. 7 (gage height, 13.88 ft, from 

high-water mark in gage house), from rating curve extended above 1,100 cfs on basis of 

contracted-opening determinations at gage heights 13.05, 13.19, 13.88, and 15.02 ft; 

minimum daily, 5.0 cfs Oct. 24, Apr. 17.

1921-55: Maximum discharge, 2,720 cfs July 23, 1938, Sept. 14, 1944, from rating 

curve extended above 1,100 cfs on basis of contracted-opening determination of peak 

flow; maximum gage height, 15.02 ft Sept. 11, 1954, from floodmark in recorder shelter; 

no flow many times.

Remarks. Records good except those for periods when waste gate was open or doubtful or 

fragmentary gage-height record, which are fair. Diversion by pumpage from Hammock well 

field, in Union, for municipal supply by Elizabethtown Water Co. probably reduces the 

flow past the station. Flow occasionally regulated at Ursino Lake dam.

Revisions (water years). WSP 726: 1931. WSP 851: Drainage area.

Gage.--Water-stage recorder. Datum of gage is 20.61 ft above mean sea level, datum of 

T929. Prior to Aug. 15, 1923, chain gage on downstream side of highway bridge at same 

site and datum. Since Oct. 1, 1952, water-stage recorder at station at Bound Brook 

used as auxiliary gage when stage is above 5.0 ft.

Average discharge. 34 years (1921-55), 759 cfs (adjusted for diversion since Oct. 1, 

1940).

Extremes. Maximum discharge during year, 34,600 cfs Aug. 19; maximum gage height, 

22.1 ft Aug. 19; minimum discharge, 2S cfs Aug. 6.

ft, from floodmark in recorder shelter), from rating curve extended above 14,000 cfs 

on basis of slope-area determination at gage heights 14.9 and 20.42 ft; minimum, 

about 15 cfs Sept. 12, 1932 (does not include water diverted to Johns-Manville plant).

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

those when fall was used as a factor, which are fair. Diversion to Johns-Manville 

plant, 1,500 ft above station, some of which was returned to river 0.6 mile below 

station. Prior to Oct. 1, 1954, these diversions were .included in figures of daily 

discharge. Slight diurnal fluctuation at low flow.

RARITAN RIVER BASIN 139

Millstone River at Blackwells Mills, N. J.

Location.--Lat 40°28'30", long 74 0 34'34", on left bank just downstream from highway bridge 

at Blackwells Mills, Somerset County, a quarter of a mile downstream from Middlebrush 

Brook.

Drainage area. 258 sq mi.

Records available.--June 1903 to December 1904 (gage heights only), August 1921 to September 1955.Published as "at Millstone" 1903-4.

Gage. Water-stage recorder. Concrete control since Nov. 18, 1933. Datum of gage is 

^6.97 ft above mean sea level, datum of 1929. June 1903 to December 1904 staff gage 

at bridge if miles downstream at different datum. Aug. 4, 1921, to Aug. 16, 1928, 

staff gage at present site and datum.

Average discharge.--33 years (1922-55), 369 cfs.

Extremes. Maximum daily discharge during year, 6,500 cfs Aug. 14; maximum gage height, 

12.42 ft Aug. 14 (backwater from Raritan River); minimum discharge, 9.0 cfs July 23, 

24 (gage height, 1.18 ft).

1921-55: Maximum discharge, 18,300 cfs Sept. 21, 1938 (gage height, 15.29 ft, from 

floodmark), from rating curve extended above 5,200 cfs on basis of slope-area determination of peak flow; minimum, about 5 cfs Sept. 16, 1923.

Remarks.--Records excellent except those for periods of backwater from Raritan River, 

which are fair. Water was probably interchanged between river and Delaware & Raritan 

Canal.

sea level, datum of 1929. September 1903 to March 1909, staff and chain gages at 

highway bridge 1.4 miles downstream at different datum.

Average discharge. 10 years (1945-55), 1,225 cfs (adjusted for diversion).

Extremes. Maximum discharge during year, 30 800 cfs Aug. 19 (gage height, 16.20 ft), 

from rating curve extended above 17,000 cfs on basis of slope-area determination at 

peak flow; minimum daily, 43 cfs Aug. 6.

1903-9, 1945-55: Maximum discharge, that of Aug. 19, 1955; minimum dally, that 

of Aug. 6, 1955.

A stage of 16.3 ft (from floodmark, present site and datum) occurred Sept. 22. 

1938.

Remarks. Records excellent except those for period of no gage-height record or those 

below 100 cfs, which are good. Figures of discharge include water diverted 150 ft 

above dam to Calco plant and returned to river just below dam. Water diverted a mile 

above station by Elizabethtown Water Co. for municipal supply. Slight diurnal 

fluctuation at low flow.

Cooperation.--Water-stage recorder graph and record of diversion to plant furnished by 

Calco Chemical Division, American Cyanamld Co.

a No gage-height records discharge estimated on basis of records for station at Manville and Millstone River at Blackwells Mills.
RARITAN RIVER BASIN 141

Green Brook at Plainfield, N. J.

Location. Lat 40°36'50", long 74 025'55", on left bank 20 ft downstream from Sycamore 

Avenue Bridge In PlainfIeld, Union County, and 1 mile upstream from Stony Brook.

Drainage area.--9.75 sq ml.

Records available. May 1938 to September 1955.

Gage. Water-stage recorder and concrete control. Datum of gage Is 70.37 ft above mean 

sea level, datum of 1929.

Average discharge. 17 years, 11.3 cfs (unadjusted).

Extremes. Maximum discharge during year, 1,270 cfs Aug. 13 (gage height, 4.32 ft), from 

rating curve extended above 220 cfs as explained below; no flow for part of many days.

1938-55: Maximum discharge, 2,890 cfs July 23, 1938 (gage height, 5.82 ft), from 

rating curve extended above 220 cfs on basis of contracted-opening determination of 

peak flow; no flow at times.

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

Water diverted for municipal supply by Commonwealth Water Co. by pumping from wells 

in headwater area of Green Brook near Summit probably reduces flow. Diurnal fluctuation caused by pumpage from wells near river in Plainfield.

Revisions (water years). WSP 921: 1938-40.

Location. Lat 41°58'00", long 75°10'50", on left bank at downstream side of railroad 

br.idge at Fishs Eddy, Delaware County, Just upstream from Fish Creek, 4| miles downstream from Beaver Kill and 11 miles upstream from confluence of East and West Branches 

near Hancock. '

Drainage area. 783 sq mi.

Records available. November 1912 to September 1955.

Gage. Water-stage recorder. Datum of gage is 950.96 ft above mean sea level, datum of 

1929. Prior to Sept. 27, 1928, staff gage at same site and datum.

Extremes. Maximum discharge during year, 27.400 cfs Aug. 19 {gage height, 15.29 ft); minimum, 80 cfs Oct. 14 (gage height, 1.62 ft).

1912-55: Maximum discharge, 53,300 cfs Aug. 24, 1933 (gage height, 20.60 ft), from 

rating curve extended above 22,000 cfs by logarithmic plotting; minimum, 67 cfs Aug. 28, 

1949; minimum gage height, 1.51 ft Aug. 4, 5, 1936.

Flood of Oct. 9, 1903, reached a stage of 23.6 ft, from descriptions obtained in 

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

cfs, from rating curve extended above 22 ,000 cfs by logarithmic plotting).

Remarks. Records good except those for periods of ice effect or shifting control, which 

are fair. Subsequent to September 1954, entire flow from 371 sq mi of drainage area, 

except for small releases and during periods of spilling, diverted from Pepacton 

Reservoir (see p. 248) through Rondout Reservoir in Hudson River basin into Kensico 

Reservoir for municipal supply of city of New York.

Revision. WSP 756: Drainage area.

DELAWARE RIVER BASIN 

Lackawaxen River at Hawley, Pa.

187

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 flow of Wallenpaupack Creek which is diverted around station to hydroelectric plant downstream.

Drainage area.--890 sq mi (excludes that of Wallenpaupack Creek, which is 228 sq mi).

Records available.--August 1938 to September 1955 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 prior to Aug. 19; staff gage read once or twice-daily thereafter. Datum of gage is 869.00 ft above mean sea level, datum of 1929, supplementary 

adjustment of 1943. Prior to 1938, chain gage at site 1,000 ft upstream at same datum.

Average discharge.--24 years (1909-12, 1913-17, 1938-55), 487 cfs.

Extremes.--Maximum discharge during year, 51,900 cfs Aug. 19 (gage height, 20.6 ft, from 

floodmark), from rating curve extended above 12,000 cfs on basis of slope-area determination at gage height 20.1 ft; minimum, 18 cfs Aug. 3, 4, 5, 6 "(gage height, 1.13 ft).

1908-19, 1938-55: Maximum discharge, that of Aug. 19, 1955; minimum daily, 7 cfs 

Aug. 20, 1911.

Flood in March 1936 reached a stage of 13.9 ft, from floodmarks (discharge, 

27,600 cfs).

Remarks. Records good except those for periods of ice effect or those subsequent to 

Aug. 18, which are fair. At 11 p.m. Aug. 18, the elevation of water surface in Lake 

Wallenpaupack was 1,182.7 ft and rising. Spill over top of roller gates began at 

7:15 a.m. Aug. 19, on basis of information furnished by Pennsylvania Power & Light 

Co. The peak stage and peak discharge of the Lackawaxen River at Hawley, which occurred at about 2 a.m., Aug. 19, were not affected by spill over gates. Daily discharges for period Aug. 19 to Sept. 1 include spill over gates which are listed below:

188 DELAWARE RIVER BASIN

Wallenpaupack Creek at Uilsonville, Pa.

Location. At hydroelectric plant of Pennsylvania Power & Light Co. at lower end of

penstock, at Kimble, 3 miles east of dam at lat 41°27'35 11 , long 75°11'10", at Wilsonville, Wayne County, and l£ miles south of Hawley.

Drainage area.--228 sq mi.

Records available.--October 1918 to September 1921 and June 1926 to September 1955 in 

reports of Geological Survey. June to December 1909 (gage heights and discharge 

measurements only) and January 1910 to September 1941 in reports of Pennsylvania 

Department of Forests and Waters.

Gage.--Prior to Nov. 3, 1925, staff gage at site 1,000 ft downstream from dam at datum 

1,146.78 ft above mean sea level, unadjusted.

Average discharge.--39 years (1913-22, 1925-55), 370 cfs (adjusted for storage).

Extremes.--1913-22, 1925-55: Maximum daily discharge, 4,840 cfs Mar. 29, 1914; no flow 

at times each year subsequent to Nov. 3, 1925.

Remarks. Records good. Daily discharge determined from flow through turbines, computed 

from records of generator putput, and flow over roller gates, computed on basis of 

head on gates. On basis of data supplied by the Pennsylvania Power & Light Co., leakage from the penstock, not included in computed discharges, varies from 1 cfs to 2 cfs 

in the late spring, summer and fall, and from 3 cfs to 5 cfs during the remainder of 

the year; leakage through the turbines during shutdown periods varied from 1 cfs to 

3 cfs. No flow over spillway or roller gates except during period Aug. 19 to Sept. 1. 

Plow regulated by Lake Wallenpaupack (see p. 248).

Cooperation.--Records of generator load, operation of powerplant, net operation head, 

and water-surface elevations in lake furnished by Pennsylvania Power & Light; Co. in 

connection with a Federal Power Commission project.

Discharge measurement made on this day.
190 DELAWARE RIVER BASIN

Delaware River at Port Jervis, N. Y.

Location Lat 41°22'20", long 74"41 "50", on right bank 250 ft downstream from bridge on 

U. S. Highways 6 and 209 at Port Jervls, Orange County, l£ miles upstream from Neverslnk River, and 6.5 miles downstream from Mongaup River.

Drainage area.--3,076 sq mi.

Records available. October 1904 to September 1955.

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

T929. 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 or 

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

Extremes. Maximum discharge during year, 233,000 cfs Aug. 19 (gage height, 23.91 ft, 

from floodmark in gage house), from rating curve extended above 89,000 cfs on basis of 

slope-area determination of peak flow; minimum, 357 cfs Oct. 10 (gage height, 0.98 ft, 

from reconstructed gage-height graph); minimum daily, 514 cfs Oct. 10.

1904-55: Maximum discharge, that of Aug. 19, 1955; minimum, 175 cfs Sept. 23, 1908 

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

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

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

logarithmic 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 doubtful gage-height 

record, which are good. Most of flow from 371 sq mi may be diverted from Pepacton 

Reservoir (see p. 248) on East Branch Delaware River out of basin for municipal supply 

of city of New York. Plow regulated by Lake Wallenpaupack and by Toronto, Cliff Lake, 

and Swinging Bridge Reservoirs (see p. 248) and smaller reservoirs. Large diurnal 

fluctuations at medium and low flow caused by powerplants on tributary streams.

Revisions (water years). WSP 756: Drainage area. WSP 1031: 1905-36.

~~to Sept. 20, 1938, staff gage at same site and datum.

Extremes.--Maximum discharge during year, 4,650 cfs Aug. 18 (gage height, 6.63 ft); minimum, 10 cfs Oct. 29 (gage height, 1.135 ft).

1937-55: Maximum discharge, 22,000 cfs Nov. 26, 1950 (gage height, 11.19 ft), from 

rating curve extended above 9,100 cfs by logarithmic plotting; maximum gage height, 

11.2 ft July 22, 1938, from floodmarks and graph based on gage readings; minimum discharge, 6.7 cfs June 27, 1953; minimum gage height, 0.795 ft Aug. 25, 27, 28, 1949.

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

are fair. Subsequent to June 1953, entire flow from 91.8 sq mi of drainage area, except 

for small releases and during periods of spilling, diverted from Neversink Reservoir 

(see p. 248) through Rondout Reservoir in Hudson River basin into Kensico Reservoir for 

municipal supply of city of New York.

mouth.

Drainage area. 302 sq mi.

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 1955 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 Navesink River at Godeffroy.

Gage. Water-stage recorder. Datum of gage is 459.66 ft above mean sea level (levels by 

Corps of Engineers). 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.

Extremes.--Maximum discharge during year, 33,000 cfs Aug. 19 (gage height, 12.49 ft), from 

rating curve extended above 11,000 cfs on basis of slope-area determination of peak 

flow; minimum, 86 cfs June 19; minimum gage height, 3.095 ft Sept. 23.

1903, 1909-14, 1937-55: Maximum discharge, that of Aug. 19, 1955; practically no 

flow July 21, 1911 (gage height, -0.3 ft, present datum).

Remarks. Records excellent except those for periods of ice effect, fragmentary gageheight record, or backwater from aquatic vegetation, which are good. Subsequent to 

June 1953, entire flow from 91.8 sq mi of drainage area, except for small releases and 

during periods of spilling, diverted from Neversink Reservoir (see p. 248) through 

Rondout Reservoir in Hudson River basin into Kensico Reservoir for municipal supply 

of city of New York. Prior to 1949, diurnal fluctuations at low and medium flow 

caused by powerplant at Cuddebackville.

Revisions.--WSP 821: Drainage area.

Rating tables, water year 1954-55, except periods of ice effect or backwater from 

aquatic vegetation (gage height, in feet, and discharge, In cubic feet per second)

196 DELAWARE RIVER BASIN 

Delaware River at Montague, N. J.

Location. Lat 41°18'30", long 74°47'50", on right bank at downstream side of bridge at 

Montague, Sussex County, three-quarters of a mile downstream from Saw Kill.

Drainage area. 3,480 sq ml.

Records available. March 1936 to February 1940 (gage heights only), February 1940 to September 1955.

Gage. Water-stage recorder. Datum of gage is 369.93 ft above mean sea level, datum of 

1929. Prior to Feb. 9, 1940, wire-weight gage on upstream side of left span of bridge 

at datum 70 ft lower.

Average discharge. 15 years, 6,552 cfs (unadjusted).

Extremes. Maximum discharge during year, 250,000 cfs Aug. 19 (gage height, 35.15 ft), 

from rating curve extended above 90,000 cfs on basis of flood-routing study; minimum, 

570 cfs Oct. 13 (gage height, 4.11 ft); minimum daily, 728 cfs Oct. 10.

1940-55: Maximum discharge, that of Aug. 19, 1955; minimum, 382 cfs Aug. 24, 1954 

(gage height, 3.83 ft); minimum daily, 412 cfs Aug. 23, 1954.

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

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

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

Remarks.--Records excellent except those for periods of ice effect or no gage-height record and those for Aug. 19, which are good. Diurnal fluctuation at medium and low flow 

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

by Toronto, Cliff Lake, Swinging Bridge, Neversink, and Pepacton Reservoirs (see p. 248). 

Diversion from Neversink Reservoir (see p. 251).

Rating tables, water year 1954-55, except periods of ice effect (gage 

height, in feet, and discharge, in cubic feet per second)

Gage.--Water-stage recorder. Datum of gage is 11.6 ft above mean sea level, datum of 

T929. Nov. 17, 1931, to Sept. 30, 1936, at site 15 ft downstream at same datum.

Average discharge. 16 years (1932-36, 1943-55), 115 cfs.

Extremes. Maximum discharge during year, 6,010 cfs Aug. 18 (gage height, 15.76 ft); minimum daily, 13 cfs Aug. 3,4.

1931-36, 1943-55: Maximum discharge, 6,230 cfs Aug. 23, 1933 (gage height, 16.05 

ft, from floodmark); minimum, 9.1 cfs Sept. 18, 1932; minimum gage 'height, 3.66 ft 

July 26, 1954; minimum daily discharge, 12 cfs Sept. 18, 26, 1932.

Maximum stage known, 23 ft in July 1937 (probably affected by backwater from railroad bridge which has since been raised and widened), from information by Baltimore & 

Ohio Railroad.

Remarks. Records good except those for periods of ice effect, doubtful gage-height record, or backwater from construction dam, which are fair. Some regulation at low flow 

caused by mills above station. Records do not include a mean discharge of 0.18 cfs 

diverted above station by plant of E. I. du Pont de Nemours & Co.

Revisions (water years). WSP 1051: 1933(M). Revised figures of discharge, in cubic feet

Tevel, datum of 1929.

Average discharge. 13 years (1942-55), 19.5 cfs.

Extremes. Maximum discharge during year, 860 cfs Aug. 13 (gage height, 2.33 ft); no flow 

part of day Aug. 15 and Sept. 20, just after waste gate was closed and water was below 

spillway.

1941-55: Maximum discharge, 3,240 cfs Nov. 25, 1950 (gage height, 4.23 ft), from 

rating curve extended above 220 cfs on basis of laboratory rating; no flow for short 

periods during many years just after waste gate was closed and water was below spillway.

Maximum discharge known, 22,000 cfs Sept. 1, 1940 (gage height, 7.98 ft, from floodmark in recorder shelter), based on slope-area determination of peak flow at site half 

a mile downstream.

Remarks. Records fair except those for periods when waste gate was open, which are poor. 

Figures of discharge represent flow over dam and through waste gate.

258 WICOMICO RIVER BASIN

Beaverdam Creek near Salisbury, Md.

Location. Lat 38"21'05", long 75 0 34'11", on upstream side of Schumaker Dam between spillway and emergency floodgates, three-quarters of a mile upstream from Beaglin Branch and 

2 miles southeast of Salisbury, Wicomico County.

Drainage area.--19.5 sq mi.

Records available. October 1929 to September 1955. Prior to October 1948, published as 

East Branch Wicomico River near Salisbury.

Gage.--Water-stage recorder and concrete spillway of dam for control. Datum of gage is 

8.93 ft above mean sea level (city of Salisbury benchmark). Prior to Sept. 28, 1938, 

at site on left bank at dam at datum 9.02 ft higher.

Average discharge.--19 years (1930-32, 1938-55), 22.9 cfs.

Extremes.--Maximum discharge during year, 338 cfs Aug. 13; maximum gage height, 11.64 ft 

Aug. 19; minimum daily discharge, 2.9 cfs Sept. 22 (leakage under dam and through 

floodgates following closing of floodgates).

1929-55: Maximum discharge not determined, occurred Aug. 23, 1933, when dam was 

partly washed out; maximum gage height, 14.31 ft Aug. 4, 1948, from high-water mark in 

well; minimum daily discharge recorded, 0.6 cfs during several periods in 1938 and 

1939 (leakage under dam and through floodgates following closing of floodgates).

Remarks. Records good except those for periods of operation of floodgates, which are 

fair, and those for periods of no gage-height record, which are poor. Records include 

flow over spillway plus leakage through floodgates. Occasional regulation at low and 

medium flow caused by mill above station.

Revisions.--WSP 1232: Drainage area.

SUSQUEHANNA RIVER BASIN 289

Susquehanna River at Conklin, N. Y.

Location. Lat 42°02'10", long 75°48'10", on left bank at downstream side of highway 

bridge at Conklin. Broome County, three-quarters of a mile downstream from Little 

Snake Creek and 3| miles downstream from Pennsylvania State Line.

Drainage area. 8,840 sq mi, approximately.

Records available. November 1912 to September 1955.

Gage.--Water-stage recorder. Datum of gage is 840.95 ft above mean sea level (levels by 

Corps of Engineers). Prior to Oct. 4, 1914, staff gage at same site and datum.

Average discharge.--48 years (1913-55), 3,633 cfs.

Extremes. Maximum discharge during year, 88,500 cfs Mar. 13 (gage height, 18.72 ft); minimum, 169 cfs Aug. 11 (gage height, 1.57 ft, from reconstructed gage-height graph, 

water below intake).

1918-55: Maximum discharge, 61,600 cfs Mar. 18, 1936; maximum gage height, 20.83 ft 

Mar. 22, 1948; minimum discharge, 106 cfs Sept. 16, 1913 (gage height, 1.32 ft).

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

record, which are good. Diurnal fluctuation at low flow caused by mill several miles 

above station. Records of chemical analyses and water temperatures for the water year 

1955 are given in WSP 1400.

Location.--Lat 42°23'40", long 75°48'15", on left bank 530 ft downstream from highway 

bridge at Smithville Flats, Chenango County, and 1,500 ft downstream from Pond Brook.

Drainage area. 83.1 sq ml.

Records available. June 1938 to September 1955.

Gage. Water-stage recorder.

Average discharge. 17 years, 140 cfs.

Extremes. Maximum discharge during year, 2,270 cfs Mar. 11 (gage height, 8.42 ft); minimum, 3.0 cfs Aug. 3 (gage height, 2.09 ft).

1938-55: Maximum discharge, 5,890 cfs Dec. 30, 1942 (gage height, 10.4 ft, from 

floodmark on outside gage), from rating curve extended above 2,800 cfs by logarithmic 

plotting; minimum, 0.48 cfs (discharge measurement) Sept. 19, 1939 (gage height, 

1.73 ft).

Remarks. Records excellent except those above 1,500 cfs or below 8 cfs, which are good, 

and those for periods of ice effect or backwater from aquatic vegetation or debris, 

which are fair. Diurnal fluctuation at low and medium flow caused by gristmill 800 ft 

above station.

294 SUSQUEHANNA RIVER BASIN 

Shackham Brook near Truxton, N. Y.

Location.--Lat 42°46'00", long 76 C 01'10", on right bank a quarter of a mile downstream 

from small tributary, three-quarters of a mile upstream from mouth, and 5 miles north 

of Truxton, Cortland County.

Drainage area. 3.12 sq mi.

Records available. November 1932 to September 1955.

Gage. Water-stage recorder and concrete control with V-notch weir. Datum of gage is 

1,281.52 ft above mean sea level, adjustment of 1912 (levels by Corps of Engineers).

Average discharge. 22 years (1933-55), 5.74 cfs.

Extremes.--Maximum discharge during year, 224 cfs Mar. 11 (gage height, 3.77 ft); minimum, 

0.071 cfs (gage height, 1.25 ft).

1932-55: Maximum discharge, 487 cfs June 3, 1947, from rating curve extended above 

170 cfs by logarithmic plotting; maximum gage height, 4.45 ft June 24, 1940; minimum 

discharge, 0.042 cfs Sept. 4, 1953 (gage height, 1.20 ft), except during period of 

dredging Sept. 10, 1954, when discharge was 0.006 cfs (gage height, 1.09 ft).

Remarks.--Records good except those for periods of ice effect or fragmentary or no gageheight record, which are fair. This station is operated in connection with a study of 

the effect of reforestation on streamflow. In addition to records of streamflow, 

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

records of ground-water levels for the water year 1955 are published in WSP 1404.

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

fragmentary or no gage-height record, which are fair. This station is operated in connection with a study of the effect of reforestation on streamflow. In addition to 

records of streamflow, records of precipitation, temperature, and. ground-water levels 

are collected. Weekly records of ground-water levels for the water year 1955 are 

published in WSF 1404.

316 SUSQUEHANNA RIVER BASIN

Canacadea Creek near Hornell, N. Y.

Location. Lat 42°20 I 05", long 77°41'00", on right bank 35 ft downstream from Morris 

Bridge near Hornell, Steuben County, 1.5 miles downstream from Almond Dam, and 

2 miles upstream from mouth.

Drainage area.--58.7 sq mi.

Records available. October 1940 to December 1942, October 1944 to September 1955.

Gage.--Water-stage recorder and concrete control. Oct. 23, 1940, to Dec. 31, 1942, at 

site 185 ft upstream at different datum.

Average discharge. 13 years (1940-42, 1944-55), 62.5 cfs (adjusted for storage).

Extremes. Maximum discharge during year, 1,860 cfs Mar. 3 (gage height, 3.68 ft); minimum, 4.2 cfs July 20-23 (gage height, 0.785 ft).

1940-42, 1944-55: Maximum discharge, 9,430 cfs May 17, 1945 (gage height, 

5.14 ft), from rating curve extended above 3,400 cfs by logarithmic plotting; maximum 

gage height, 6.65 ft June 3, 1947; minimum discharge, 2.2 cfs July 22, 1953 (gage 

height, 0.72 ft).

Maximum discharge known, 21,000 cfs during flood in July 1935, by slope-area determination of peak flow.

Remarks. Records good except those for periods of ice effect, backwater from debris or 

aquatic vegetation, or no gage-height record, which are fair. Since October 1948, 

flow regulated by Almond Reservoir (see preceding page).

SUSQUEHANNA RIVER BASIN 317

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

Locatlon.--Lat 42°18'50", long 77°39'05", on right bank 200 ft upstream from Erie Railroad bridge In Hornell, Steuben County, 0.25 mile upstream from Crosby Creek, and 

1.5 miles downstream from Canacadea Creek.

Drainage area. 159 sq ml.

Records available.--August 1942 to September 1955.

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.--13 years, 160 cfs.

Extremes. Maximum discharge during year, 2,780 cfs Mar. 11 (gage height, 8.05 ft); minimum, 7.4 cfs Sept. 13, 14; minimum gage height, 0.57 ft July 20.

1942-55: 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, that of Sept. 13, 14, 1955; minimum gage height, that of July 20, 1955.

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

vegetation or debris, obstructed intake, or shifting control, which are fair. Records 

include daily diversion (about 1.3 cfs) Just above control prior to Nov. 14, 1954, when 

pumpage was discontinued by Erie Railroad Co. An unknown but relatively small amount 

of water diverted is returned to stream below 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. 312), and, since October 1948, by Almond Reservoir (see 

p. 316).

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

Carrington Creek, by city of Hornell.

Nagle Street and 30.33 ft at Walnut Street); minimum, 1,600 cfs Nov. 29, 1930, caused 

by temporary storage behind ice jam upstream (gage height, 2.48 ft at Nagle Street and 

2.56 ft at Walnut Street).

Maximum stage known during period 1786 to 1890, 26.8 ft at Walnut Street June 2, 

1889 (discharge, about 620,000 cfs).

Remarks.--Records excellent except those for periods of ice effect, which are fair. Records of chemical analyses for the water year 1955 are given in WSP 1400.

Revisions (water years). All records prior to Oct. 1, 1923, have been revised. The revision was made in connection with the power project at Conowingo, Md., a project under 

the jurisdiction of the Federal Power Commission. A complete set of revised records is 

on file at the Geological Survey, Washington, D. C., and also at the Pennsylvania Department of Forests and Waters, Division of Hydrography, Harrisburg, Pa.

SUSQUEHANNA RIVER'BASIN 387

Yellow Breeches Creek near Camp Hill, Pa.

Location. Lat 40°13'30", long 76°53'50", on left bank 50 ft downstream from single span 

highway bridge, 150 ft downstream from Olmsted's milldam, 1 mile southeast of Camp Hill, 

Cumberland County, and 3.1 miles upstream from mouth.

Drainage area. 216 sq mi.

Records available. October 1918 to December 1919, June 1954 to September 1955 in reports 

of Geological Survey. March 1909 to December 1919 in reports of Water Supply Commission 

of Pennsylvania. Prior to June 1954, published as "at Olmsted's Mill."

Gage. Water-stage recorder. Datum of gage is 301.49 ft above mean sea level, datum of 

1929, supplementary adjustment of 1943. March 1909 to December 1919 chain gage at 

bridge 50 ft upstream at same datum.

Average discharge. 9 years (1910-16, 1917-19, 1954-55), 304 cfs.

Extremes.--Maximum discharge during year, 1,470 cfs Mar. 22 (gage height, 4.95 ft); minimum, 47 cfs June 1, Aug. 4 (gage height, 0.42 ft); minimum daily, 90 cfs Aug. 6.

1909-19, 1954-55: Maximum discharge, 5,550 cfs Aug. 22, 1915 (gage height, 8.61 ft, 

from graph based on gage readings), from rating curve extended above 3,700 cfs; minimum, 31 cfs Aug. 2, 1954 (gage height, 0.31 ft); minimum daily, 79 cfs Aug. 2, 1954.

Flood of July 22, 1953, reached a stage of 9.4 ft, from floodmarks (discharge, 

3,940 cfs, from rating curve extended above 2,500 cfs).

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

which are fair. The Mechanicsburg Water Co. diverted water at a point about 4 miles 

above station for municipal water supply, equivalent to a mean discharge at station 

of 1.0 cfs. Some diurnal fluctuation at low flow caused by mill above station.

Sept. 14, 1954.

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

urumown cause, which are good, and those for period of doubtful gage-height record, 

which are fair. Slight diurnal fluctuation at low and medium flow caused by mill 

above station. Records do not include a mean discharge of 1.12 cfs diverted above 

station for municipal supply of Westminster; sewage effluent discharged into Little 

Pipe Creek.

Drainage area.--106 sq mi.

Records available. October 1948 to September 1955.

Gage. Water-stage recorder and concrete control. Datum of gage is 1,276.40 ft above mean 

sea level (Corps of Engineers benchmark).

Average discharge. 7 years, 171 cfs (adjusted for storage).

Extremes. Maximum discharge during year, 6,630 cfs Oct. 16 (gage height, 7.70 ft); minimum, 3.6 cfs Sept. 26 (gage height, 0.80 ft); minimum daily, 12 cfs Mar. 20, Apr. 5-13, 

July 26, Aug. 16.

1948-55: Maximum discharge, that of Oct. 16, 19S4; minimum, 0.5 cfs July 31, 

Aug. 1, 1951; minimum daily, 0.6 cfs July 27-31, Aug. 5, 6, 9, 10, 1951.

Remarks. Records excellent except those for period of Telemark gage readings and those 

below 25 cfs, which are good. Diversions above station by Baltimore & Ohio Railroad 

and by cities of Frostburg and Westernport for municipal supply. Flow regulated by 

Savage River Reservoir since December 1950 (capacity, 20,000 acre-ft).

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

Remarks --Records good except those for periods of ice effect or no gage-height 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 Welch Hill. Records include drainage from numerous active and 

abandoned coal mines.

428 POTOMAC RIVER BASIN 

North Branch Potomac River at Pinto, Md.

Location.--Lat 39°33 1 57", long 78°50'22", on right bank at downstream side of Western

Maryland Railway bridge at Pinto, Allegany County, 3.6 miles downstream from Mill Creek.

Drainage area. 596 sq mi.

Records available. October 1938 to September 1955.

Gage. Water-stage recorder. Datum of gage is 648.23 ft above mean sea level (Corps of 

Engineers benchmark). Prior to Dec. 9, 1938, wire-weight gage at highway bridge 250 ft 

downstream at same datum.

Average discharge. 17 years, cfs (unadjusted).

Extremes. Maximum discharge during year, 37,000 cfs Oct. 16 (gage height, 23.23 ft); minimum, 104 cfs Aug. 4 (gage height, 1.79 ft).

1938-55: Maximum discharge, that of Oct. 16, 1954; minimum, 31 cfs Dec. 18, 19, 1943 

(gage height, 1.37 ft).

Flood of Mar. 29, 1924, reached a stage of about 24 ft (discharge, about 55,000 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 ice effect or doubtful or no gageheight record, which are fair. Some regulation at low flow caused by Stony River 

Reservoir, 66 miles above station (see p. 421) and since December 1950, by Savage River 

Reservoir (see p. 424).

Revisions (water years).--WSF 1332: 1943.

POTOMAC RIVER BASIN 

North Branch Potomac River near Cumberland, Md.

431

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 1955.

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.--26 years, 1,214 cfs (unadjusted).

Extremes. Maximum discharge during year, 38,500 cfs Oct. 16 (gage height, 23.85 ft, from 

reconstructed gage-height graph); minimum, 99 cfs July 20.

1929-55: 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 computed from once-daily tape-gage readings, and 

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. 421), and since December 1950, by reservoir on Savage River (see p. 424). 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.

POTOMAC RIVER BASIN 437

Big Spring at Masonville, W. Va.

Location.--Lat 38°55'15", long 79°05'10", on right bank of Spring Run, at State fish 

hatchery, Masonville, Grant County, and 6 miles southeast of Petersburg.

Records available.--August 1945 to September 1955.

Gage.--Water-stage recorder and concrete control. Altitude of gage is 1,180 ft (from 

Topographic map). Prior to May 14, 1951, water-stage recorder at site half a mile 

upstream at different datum. May 14, 1951, to Feb. 5, 1952, staff gage at site 200 ft 

downstream at different datum.

Average discharge. 10 years, 13.6 cfs.

Extremes.--Maximum discharge during year, 273 cfs Aug. 18 (gage height, 2.53 ft); minimum daily, 6.3 cfs Aug. 5, 6.

1945-55: 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 except those for periods of doubtful or no gage-height record, 

which are poor. 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.

Drainage area. 4,073 sq mi.

Records available.--October 1932 to September 1955.

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. 23 years, 4,104 cfs.

Extremes. Maximum discharge during year, 123.000 cfs Aug. 19 (gage height, 32.40 ft); minimum, 384 cfs Aug. 6 (gage height, 2.49 ft).

1932-55: 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 ice effect or doubtful gage-height 

record, which are good. Slight regulation at low flow from powerplants upstream. Low 

flow affected slightly by Stony River Reservoir (see p. 421) and since December 1950 by 

Savage River Reservoir (see p. 424). Record of water temperatures for the water year 

1955 are given in WSP 1400.

Extremes.--Maximum discharge during year, 10,700 cfs Aug. 19 (gage height, 17.34 ft, from 

floodmark); minimum observed, 6.3 cfs Oct. 9; minimum gage height, 1.57 ft Aug. 4.

1928-31 1938-55: Maximum discharge, 22,400 cfs Oct. 15, 1942 (gage height, 25.17 

ft, from floodmarks), from rating curve extended above 6,200 cfs' on basis of current 

meter measurement of 14,500 cfs made at Hedgesville; minimum observed, 0.9 cfs Aug. 6, 

1930.

Maximum stage known prior to October 1942, 25.0 ft Mar. 17 or 18, 1936, from floodmarks (discharge, 22,000 cfs, from rating curve extended above 6,200 cfs).

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

record, which are poor.

Location. Lat 39°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 1955.

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.--59 years (1896-1955), 9,436 cfs.

Extremes.--Maximum discharge during year, 214,000 cfs Aug. 20 (gage height, 29.08 ft); 

minimum, 1,000 cfs Oct. 7 (gage height, 0.60 ft).

1895-1955: Maximum discharge, 480,000 cfs Mar. 19, 1936 (gage height, 41.03 ft), 

from rating curve extended above 300,000 cfs 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 periods of ice effect, which are good. 

Low flow affected slightly since 1913 by Stony River Reservoir (see p. 421) and 

since December 1950 by Savage River Reservoir (see p. 424).

Revisions (water years). WSP 192: 1895-1905. WSP 781: 1924(M).

474 POTOMAC RIVER BASIN

Monocacy River at Bridgeport, Md.

Location. Lat 39°40'43", long 77°14'06", on right bank 60 ft downstream from bridge on 

State Highway 32, at Bridgeport, Carroll County, 0.9 mile upstream from Cattail Branch, 

3.4 miles northwest of Taneytown, and 4.8 miles downstream from confluence of Rock and 

Marsh Creeks at Pennsylvania-Maryland State line.

Drainage area. 173 sq mi.

Records available.--May 1942 to September 1955.

Gage.--Water-stage recorder. Concrete control since Sept. 15, 1947. Datum of gage is 

340.83 ft above mean sea level (Corps of Engineers benchmark). Prior to May 3, 1946, 

staff gage and crest-stage indicators at site 0.3 mile downstream at datum 0.98 ft lower.

Average discharge. 13 years, 204 cfs.

Extremes.--Maximum discharge during year, 8,390 cfs Mar. 22 (gage height, 13.66 ft); minimum, 1.3 cfs Oct. 3, 4, 5.

1942-55: Maximum discharge, 15,000 cfs May 21, 1943 (gage height, 20.53 ft, former 

site and datum), from rating curve extended above 6,700 cfs on basis of logarithmic 

plotting and velocity-area studies; minimum, 0.1 cfs Aug. 27, 28, 1944.

Maximum stage known, about 25 ft present site and datum, Aug. 24, 1933, from floodmarks; stage exceeded that of June 1889, from information by local residents.

Revisions.--The maximum discharge for the water year 1944 has been revised to 12,400 

cfs Nov. 9, 1943 (gage height, 18.10 ft), superseding figure published in WSP 1001.

Remarks. Records excellent except those below 10 cfs or those for periods of ice effect, 

which are good. Occasional regulation at low flow from unknown source above station.

Drainage area. 8.10 sq mi (revised).

Records available. August 1947 to September 1955.

Gage.. Water-stage recorder and concrete control. Altitude of gage is 585 ft (from topographic map).

Average discharge. 8 years, 9.27 cfs (adjusted for inflow).

Extremes.--Maximum discharge during year, 1,260 cfs Aug. 13 (gage height, 7.05 ft), from 

rating curve extended above 130 cfs as explained below; minimum, 3.0 cfs Oct 11 (gage 

height, 1.50 ft); minimum daily, 3.4 cfs July 27.

1947-55: Maximum discharge, 1,480 cfs Sept. 1, 1952 (gage height, 7.60 ft), from 

rating curve extended above 130 cfs on basis of slope-area determination at gage heights 

3.85 and 5.50 ft, and contracted-opening determination at 7.60 ft; minimum, 1.4 cfs 

July 1, 1954, result of storage behind temporary earth dam upstream; minimum daily 

3.0 cfs Sept. 13, 1947.

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

which are fair. Records include pumpage from Patapsco River basin for municipal supply 

of Westminster which is discharged as sewage into Little Pipe Creek above station.

Potomac River near Washington, D. C.

Location. Lat 38°57'36", long 77°08'33", on right bank 1 mile upstream from Little Falls 

Dam, l£ miles northeast of Langley, Fairfax County, Va., 2 miles upstream from District 

of Columbia boundary line, and Z\ miles upstream from Chain Bridge.

Drainage area. 11,560 sq mi.

Records available. March 1930 to September 1955.

Gage.--Water-stage recorder. Datum of gage is 38.00 ft above mean sea level, adjustment 

of 1912. Prior to June 7, 1930, staff gage at same site and datum.

Average discharge. 25 years, 11,340 cfs (adjusted for diversions).

Extremes.--Maximum discharge during year, 216,000 cfs Aug. 20 (gage height, 17.60 ft); 

minimum, 880 cfs Oct. 8.

1930-55: Maximum discharge, 484,000 cfs Mar. 19, 1936 (gage height, 28.1 ft); minimum daily, 448 cfs Aug. 25, 1930 (does not include 334 cfs diverted at Great Falls for 

water supply).

Flood of June 2, 1889, was of approximately the same magnitude as that of Mar. 19, 

1936.

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

or once-daily Telemark-gage readings, which are good. Diversion at Great Falls through 

aqueducts for municipal water supply of Washington, D. C. Low flow affected slightly 

by Stony River Reservoir (see p. 421) and since December 1950 by Savage River Reservoir 

(see p. 424).

Revisions. WSP 726: Drainage area.

a Doubtful or no gage-height record; discharge estimated on basis of weather records, 1 discharge 

measurement, and records for Accotink Creek near Annandale.
POTOMAC RIVER BASIN 

Accotink Creek near Aocotink Station, Va.

497

Location. Lat 38°45'15", long 77°12'09", on left bank 100 ft upstream from highway bridge, 

1.4 miles northwest of Accotink Station, Fairfax County, and 1.6 miles downstream from 

Calamo Branch.

Drainage area. 37.0 sq mi.

Records available.--May 1949 to September 1955.

Gage.--Water-stage recorder. Altitude of gage is 121 ft (by barometer).

Average discharge.--6 years, 39.6 cfs.

Extremes. Maximum discharge during year, 3,120 cfs Aug. 13 (gage height, 14.21 ft); minImum daily, 0.6 cfs many days in November, December; minimum gage height, 3.71 ft 

Dec. 8.

1949-55: Maximum discharge, that of Aug. 13, 1955; minimum daily, that of November, 

December 1954; minimum gage height, 2.96 ft Sept. 10, 1949.

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

which are poor. Field maneuvers by U. S. Army cause some regulation. Occasional regulation by Fort Belvoir Reservoir about 3 miles upstream. No diversion from reservoir; 

water travels in stream channel to a point near U. S. Highway 1, downstream from gage, at 

which point it is pumped to Fort Belvoir treatment plant. Records of chemical analyses 

for the water year 1955 are given in WSP 1400.

534 DISCHARGE MEASUREMENTS AT POINTS OTHER THAN GAGING STATIONS

Measurements of streamflow in the North Atlantic slope basins, New York to York River 

made at points other than regular gaging stations are given in the following table. Most 

of these measurements were made during periods of base flow when streamflow is primarily 

from ground-water storage. Measurements believed to have been made under base-flow conditions are identified by an asterisk (*) to the left of the discharge figure. These 

measurements when correlated with the simultaneous discharge of a nearby stream where 

continuous records are available will give a picture of the low-flow potentiality of 

stream. The column headed, "Measured previously" shows the water years in which measurements were made at the same, or practically the same, site.

Determinations of peak flow at points other than regular gaging stations are given in 

a separate table on page 548.

Discharge measurements made at points other than gaging stations In the North Atlantic slope 

basins, New York to York River during water year 1955

Streams on Long Island 

Streamflow Investigation, Nassau and Suffolk Counties, New York

An Investigation of streamflow characteristics of Nassau and Suffolk Counties Is being made for 

the purpose of determining the water loss by runoff from surface streams Into the Atlantic Ocean 

and to study relationships between dry-weather streamflow and ground-water conditions and to correlate the flow from small areas with those on which streamflow records are available for a complete 

Inventory of surface flow and available water supplies from all sources. Current-meter measurements 

are made at selected points throughout the Island at the same time and under the same general conditions as at regular gaging stations, approximately four times a year, under varying conditions of 

streamflow. These results, together with the continuous streamflow records, ground-water records 

and geologic studies of the area, indicate the water-supply potentials of this area with particular 

reference to probable loss of available supplies from sustained surface flow, under typical 

conditions.

The measurements on each stream are listed in order, proceeding clockwise around the island and 

are directly tributary to Atlantic Ocean except where otherwise noted. Drainage areas have not 

been determined because existing maps are inadequate and also because much of the surface flow is 

derived from ground-water storage that may originate from an area differing from that of the surface 

drainage.
