SCOPE OF WORK

This volume is one of a series of 20 reports presenting records of stage, discharge, 

and content, of streams, lakes, and reservoirs in the United States during the 1960 water 

year. Since 1888, when the United States Geological Survey first studied streamflow in 

relation to problems of irrigation, similar records have been obtained at more than 15,500 

gaging stations in the 50 States. On September 30, 1960, the Geological Survey and cooperating organizations were maintaining 7,300 gaging stations. Partial-record stations for 

low flow or for flood flow have been operated at many other points. In addition, discharge measurements are made at miscellaneous sites. The records for the 1960 water year 

at gaging stations, partial-record stations, and miscellaneous sites in the Nor^h Atlantic 

slope basins, New York to York River, are given in this report.

Information of a more detailed nature than that published for most of the gating stations given in this report is on file in the district offices listed above. All gagingstation records for the States of Maryland, New Jersey, and Virginia, and some records 

for the States of New York and Pennsylvania and for the Delaware River basin have been 

analyzed by electronic computer to give; (1) the number of days in each year thst the 

daily discharge was between selected limits (duration tables); and (2) the lowest mean 

discharge for selected numbers of consecutive days. In addition the records for Maryland 

and New Jersey give the highest mean discharge for selected numbers of consecutive days in 

each year. Provisional records of discharge, information on the availability of electronic computer results, and other unpublished data concerning the gaging-station records 

may generally 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:

Gaging station is a particular site on a stream, canal, lake, or reservoir where systematic observations of gage height or discharge are obtained. When used in connection with 

a discharge record, the term is applied herein only to those gaging stations where a continuous record of discharge is obtained.

Partial-record station is a particular site where limited streamflow data are collected 

systematically over a period of years for use in hydrologic analyses.

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.

tjublc 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 (in.) shows the depth to which the drainage area would be covered if 

all the runoff for a given time period were uniformly distributed on it.

Acre-foot (ac-ft) is the quantity of water required to cover an acre to the depth of 

1 foot and is equivalent to 43,560 cubic feet.

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.
4 SURFACE WATER SUPPLY, 1960, PART 1-B

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.

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

published reports.

DOWNSTREAM ORDER AND STATION NUMBERS

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 th3 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.

As an added means of identification each gaging station and partial-re lord station has 

been assigned a station number. The numbers have been assigned in the sanrs downstream 

order used in this report. In assigning station numbers, no distinction is made between 

partial-record stations and regular gaging stations, so that the station nanber for a 

partial-record station indicates downstream-order position in a list made up of both types 

of stations. Gaps are left in the numbers to allow for new stations that may be established; hence the numbers are not consecutive. The complete number for each station Includes the part number, but the station number as shown In this report, just to the left 

of the station name, consists of only the essential digits of the complete number. For 

example, for a station with the complete number IB-3210.00, the station nunber shown in 

this report is 3210. The notation to the left of the hyphen is the part number; it is 

IB for all stations in this report, with one exception, and is therefore onitted. The 

exception is station No. 4-2520.00, Black River Canal (flowing south) near Boonville, 

N. Y. , which diverts from Black River in the St. Lawrence River basin to the Hudson River 

basin. This station was numbered as a Part 4 station; the "4-" is therefore included in 

the station number shown in this report.
SURFACE WATER SUPPO, I960', PART 1-B 5 

EXPLANATION OP 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 read'ngs on a 

nonrecording gage or from a water-stage recorder that gives a continuous recorl 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.

Rating tables giving the discharge for any stage are prepared from stage-discharge 

relation curves defined by discharge measurements. If extensions to the rating curves are 

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

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

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

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

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

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

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

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

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

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

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

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 ir 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 marner. 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 obaervers and engir°ers, and 

comparable records of discharge for other stations in the same or nearby basinr. 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, s skeleton 

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

of the stream. Records are published for the Ttater year which begins on October 1 and 

ends on September 30. A calendar for the water year 1959 is shown on page TV for the 

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

6 SURFACE WATER SUPPLY, 1960, PART 1-B

The description of the station gives the location, drainage area, record? 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 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 t^e 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 whsre 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 minimuTi 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 is 

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 gage, or a nonrecording gage read at the time of the crest. If the maximum 

gage height did not occur at the same time as the maximum discharge, It Is given separately. Information pertaining to the accuracy of the records and conditions which affect 

the natural flow at the gaging station is given under "Remarks."

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.
EXPLANATION OF DATA 7

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. Discharge for the month may 

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

(line headed "In."), or in acre-feet (line headed "Ac-ft"). 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
8 SURFACE WATER SUPPLY, 1960, PART 1-B

a table showing dally contents or stage Is given. A skeleton table of capacity at given 

stages Is published each year for all reservoirs for which records are published on a 

dally basis, but Is not published for reservoirs for which only monthly data are given.

At many gaging stations water samples are collected from the streams for the purpose of 

making chemical analyses, computing dissolved solids, suspended sediment loads, and 

particle-size distribution, or measuring water temperatures. For most of these samples 

the results are published In an annual series of water-supply papers entitled "Quality of 

Surface Waters of the United States" which Is Issued In four volumes. In this report 

under "Remarks" a reference Is made to quallty-of-water records collected at gaging stations on a regular basis and published In the quallty-of-water reports. At many other 

gaging stations quallty-of-water data are obtained at Irregular Intervals and published 

as "miscellaneous analyses" In quallty-of-water reports; such records are not referred to 

In "Remarks" paragraph In this report. At many gaging stations water temperature Is 

obtained also at the time a discharge measurement Is made; such temperature readings are 

not reported In the quality-of-water annual reports.

Data collected at partial-record stations and at miscellaneous sites are given at the 

end of each report. Partial-record stations are presented In two tables. The first Is a 

table of discharge measurements at low-flow partial-record stations, and the second is a 

table of annual maximum stage and discharge at crest-stage stations. Discharge measurements at miscellaneous sites are given In a third table. Occasionally, a series of discharge measurements are made within a short time period to Investigate the seepage gains 

or losses along a reach of a stream or to determine the low-flow characteristics of an 

area. Such measurements are given In special tables after the list of measurements at 

miscellaneous sites.

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.

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

natural runoff, owing to diversion, consumption, regulation by storage, ircrease or decrease In evaporation due to artificial causes, or to other factors. For such stations, 

figures of cubic feet per second per square mile and of runoff In inches are not published 

unless satisfactory adjustments can be made for diversions, for changes ir contents of 

reservoirs, or for other changes incident to use and control. Evaporatior from a reservoir Is not included in the adjustments for changes in reservoir contents, unless It Is so 

stated. Even at those stations where adjustments are made, large errors In computed runoff may occur when relatively large negative adjustments are made or when evaporation is 

large In comparison with the observed discharge.
PUBLICATIONS

Many gaging stations on streams In the irrigated areas of the United States are situated above most of the diversions from those streams, and therefore the discharge recorded 

does not actually show the water supply available at the stations for further envelopment,

because water must first be supplied to existing irrigation systems.

i

PUBLICATIONS

Basic data for gaging stations are published in an annual series of reports consisting 

of 20 volumes, including one each for the States of Alaska and Hawaii. The area of the 

other 48 States is divided into 14 parts whose boundaries coincide with certain natural 

drainage lines. Formerly, the annual series of reports on surface water supply consisted 

of 14 volumes, one for each of the 14 parts. Beginning with the reports for 1951, the 

records for the 48 States were 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

A compilation of records for the area covered by this report through September 1950 

has been published as Water-Supply Paper 1302. That report contains a summary of monthly 

and annual discharges for all previously published records as well as some records not contained in the annual series of water-supply papers. All records were reexamined and revised where warranted. Estimates of discharge were made to fill short gaps whenever 

practical.

The reports listed in the foregoing tables contain the customary record? of discharge 

collected during the systematic operation of gaging stations. Detailed information on the 

stage and discharge of many streams during major floods has been included in special reports on these floods published by the Geological Survey or other agencies. The more 

recent of these special reports also contain other pertinent hydrologic information and 

analyses and compilations of data relating to earlier notable floods. The following is

HYDROLOGIC CONDITIONS

Excessive streamflow occurred In some parts of the area covered by this report In each 

month except March, July, and August. For the key gaging station In New York, the November mean discharge was record-high for the month.

Frequent flooding In scattered areas was generally limited to bankfull stages. However, 

considerable damage was caused by floods In New York In June, In Maryland In July, and on 

coastal streams throughout the area In September. The September floods, caused by a 

tropical hurricane,resulted In the maximum discharge at many gaging stations having 20 to 

30 years of record.

Streamflow was deficient In New York, northern New Jersey, and Pennsylvania In March.

Figure 2, on page 14, for which records of three long-term gaging stations were used, 

shows a comparison of the monthly and yearly mean discharge for the 1960 water year with

22 STREAMS ON LONG ISLAND

3035. Cold Spring Brook at Cold Spring Harbor, N. Y.

Location. Lat 40°51'25", long 73°27'50", on left bank 270 ft upstream f-om 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 1960.

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

level, datum of 1929.

Average discharge.--10 years, 2.65 cfs (unadjusted).

Extremes. Maximum discharge during year, 31 cfs Mar. 14 (gage height, 0.82 ft); maximum 

gage height, 2.02 ft Dec. 29 (backwater from high tide); minimum discharge, 0.9 cfs 

Apr. 14, 15 (gage height, 0.14 ft).

1950-60: Maximum discharge, 108 cfs Sept. 11, 1954 (gage height, 1.332 ft, backwater from aquatic vegetation), from rating curve extended above 28 cfs by logarithmic 

plotting; maximum gage height, 5.342 ft Aug. 31, 1954 (backwater from high tide), from 

high-water mark; 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 backwater from aquatic vegetation, 

which are fair, and those for periods of no gage-height record, which are poor. 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 op3rated 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 529 for results of discharge measurements of Long 

Island streams at sites other than regular gaging stations.

32 STREAMS ON LONG ISLAND

3080. 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 and 

3,000 ft upstream from mouth.

Drainage area. About 23 sq ml.

Records available. October 1944 to September 1960.

Gage. Water-stage recorder and concrete control. Datum of gage is 6.70 f"; above mean sea 

level, datum of 1929.

Average discharge. 16 years, 9.80 cfs.

Extremes. Maximum discharge during year, 136 cfs Sept. 12 (gage height, 2.11 ft, backwater from aquatic vegetation); minimum, 4.46 cfs June 27, 28 (gage height, 0.305 ft); 

minimum daily, 5.27 cfs Oct. 21, 22.

1944-60: Maximum discharge, that of Sept. 12, 1960; minimum, 2.65 cfs Aug. 3, 1955 

(gage height, 0.232 ft, backwater from aquatic vegetation); minimum daily, 3.35 cfs 

Aug. 3, 1955, Aug. 2, 1957.

Revisions. Figures of maximum discharge for the water years 1955 ani 1956 have been 

revised to 95 cfs Aug. 12, 1955 (gage height, 1.645 ft, backwater from aquatic vegetation and weeds below control) and 98 cfs Oct. 16, 1955 (gage height, 1.672 ft, from 

reconstructed gage-height graph), superseding those published in WSP 13^9 and 1432, 

respectively.

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

which are good. Flow regulated slightly by pumping operations at railroad and occasionally by ponds above station. Indeterminate effect caused by pumpag? for watersupply purposes at Smith Street substation a quarter of a mile northwest of gage. 

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 ap3 collected, 

some of which are published in water-supply papers. See page 529 fbrreTultsf of discharge measurements of Long Island streams at sites other than regular gaging stations.

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

Average discharge.--22 years (1937-59), 12.26 ofs.

Extremes.--Maximum discharge during period October to November 1959, 46 cfs Oct. 24 (gage 

height, 0.99 ft); minimum, 5.2 cfs Oct. 12 (gage height, 0.42 ft).

1903, 1936-59: Maximum discharge, 180 cfs Aug. 12, 1955 (gage height, 1.833 ft), 

Includes 9 cfs of flow bypassing gage; minimum, 2.66 cfs Aug. 1, 1954 (gage height, 

0.322 i't).

Remarks.--Records good. Gage rendered Inoperative for several months, beginning Dec. 1, 

1959, as a result of stream straightening and sedimentation-basin-construction project 

by village of Massapequa and County of Nassau. 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 529 for results of discharge measurements of Long 

Island streams at sites other than regular gaging stations.

Location. Lat 40°40'00", long 73°39'30", on left bank 100 ft downstream from Lakeview 

Avenue and south line of Malverne, Nassau County.

Drainage area. About 10 sq ml.

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

December 1936 to September 1960.

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

iy.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.--23 years (1937-60), 5.67 cfs.

Extremes. Maximum discharge during year, 346 cfs Sept. 12 (gage height, 4.51 ft), from 

rating curve extended ibove 95 cfs on basis of flow-through-culvert measurement of peak 

flow; minimum, 1.3 cfs Sept. 10 (gage height, 0.73 ft); minimum dally, 1.4 cfs Oct. 6-8, 

13 19-22.

'1936-60: Maximum discharge, that of Sept. 12, 1960; minimum, 0.13 cfs Feb. 15, 

1940 (gage height, 0.196 ft); minimum daily, 0.18 cfs Nov. 25, 1941, Feb. 8 and Oct 23, 

1942.

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

Prior to Feb. 20, 1956, flow occasionally regulated by Pines Pond. Indeterminate 

diversion from Pines Pond for emergency municipal water supply for city of New York 

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

papers. See page 529 for results of discharge measurements of Long Island streams at 

sites other than regular gaging stations.

Average discharge. 48 years (1910-21, 1923-60), 920 cfs.

Extremes. Maximum discharge during year, 15,900 cfs Sept. 13 (gage height, 12.73 ft); 

minimum, 70 cfs Sept. 8; minimum daily, 154 cfs Sept. 9.

1910-60: 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 measurements at gage heights 

17 8 and 21.15 ft; minimum, 24 cfs Sept. 14, 1913; minimum dally, 30 cfs Sept. 14, 

1913.

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

fluctuation at medium and low flow caused by powerplants above station.

66 HUDSON RIVER BASIN

4-2520. Black River Canal (flowing south) near Boonvllle, N. Y.

Location.--Lab 43 0 27'20", long 75°19'25", on left bank at lock 69, 200 ft downstream from 

bridge on State Highway 46 and 2 miles south of Boonville, Onelda County.

Records available.--September 1915 to September 1960 (canal seasons only prior to October 

1942 and since October 1957).

Gage. Water-stage recorder and concrete control. Datum of gage is 1,105.56 ft above 

mean sea level, datum of 1929. Prior to June 7, 1929, station was operated as a slope 

station on summit level of canal. Auxiliary water-stage recorder with concrete control on right bank of Lansingkill spillway, 100 ft downstream from spillway headgates, 

600 ft upstream from lock 70, and half a mile upstream from lock 69.

Extremes.--1915-60: Maximum daily discharge recorded, 323 cfs Nov. 30, 1915; partically 

no flow at times when no water is being diverted.

Remarks. Records good except those for period of no gage-height record at auxiliary gage, 

which are fair. This record shows combined flow in Black River Canal and Lansingkill 

spillway, and represents total diversion from Black River at Forestport, through 

Forestport feeder, into Mohawk River basin. Discharge during periods when no water 

was diverted, made up of leakage through headgates and runoff from area draining into 

canal above station.

HUDSON RIVER BASIN 67

3360. Mohawk River below Delta Dam, near Rome, N. Y.

Location. Lat 43°15'50", long 75°26'10", on right bank at Spring Brook fish hetchery, 

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

Drainage area.--ISO sq mi.

Records available. July 1921 to September 1960. Monthly discharge only for some periods, 

published in WSP 1302.

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

datum). Prior to Jan. 24, 1937, staff gage at stie 200 ft downstream at saire datum.

Average discharge. 39 years, 391 cfs (unadjusted).

Extremes. Maximum discharge during year, 3,960 cfs Apr. 24 (gage height, 7.91 ft); minimum, 46 cfs Mar. 23 (gage height, 0.82 ft); minimum daily, 135 cfs Mar. 25.

1927-60: 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 dally, 45 cfs Jar. 17, 1931.

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

canal navigation season, water is diverted from Black River through Forestpcrt feeder 

and Black River Canal (flowing south) Into Delta Reservoir above station. Flow almost 

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.

Extremes. Maximum discharge during year (river channel only), 23,000 cfs Nov. 28 (gage 

height, 16.90 ft); minimum (river channel only), 311 cfs June 7 (gage height, 4.00 ft); 

minimum daily (including canal). 623 cfs Aug. 20.

1927-60: 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 good except those for periods of ice effect or no gage-height record, 

which are fair. Records of daily discharge include diversion at Rocky Rift Dam into 

Erie (Barge) Canal for power and lockage at lock 16, near St. Johnsville. During canal 

navigation season, water is received from Black River basin through Blac'c River Canal, 

flowing south (see p. 66 ), and Lansing Kill, and from Chenengo River ba^in through 

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

Oswego River basin through summit level of Erie (Barge) Canal between Neri London and 

Utica. Diurnal fluctuation caused by powerplants and locks and dams on Erie (Barge) 

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

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

Revisions (water years). WSP 741:

HUDSON RIVER BASIN 75

3575. Mohawk River at Cohoes, N. Y.

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

Mohawk Power Corp. in Cohoes, Albany County, 1-J miles upstream from mouth.

Drainage area,--3,456 sq mi.

Records available. December 1917 to September 1960. Monthly discharge only for some 

periods, published in WSP 1302. Published as "at Crescent Dam" prior to July 1925.

Gage.--Water-stage recorder at present site since Oct. 20, 19?5. Datum of gage is 49.13 

Ft above mean sea level, datum of 1929. Dec. 1, 1917, to July 16, 1925, water-stage 

recorder at site 1-J- miles upstream at Crescent Dam at datum 130.87 ft higher. July 17 

to Oct. 19, 1925, powerplant gage at present site.

Average discharge.--7 years (1918-25), 5,820 cfs (includes diversion at lock 6); 35 years 

(1925-60) , 5,688 cfs (unadjusted).

Extremes.--Maximum discharge during year, 83,300 cfs Apr. 4 (gage height, 20.15 ft); minimum, 74 cfs July 28 (gage height, 3.83 ft); minimum daily, 304 cfs Aug. 28.

1918-60: 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 of discharge 1918-25 include flow over spillway, through 

Erie (Barge) Canal powerhouse, and diversion through lock 6 at Crescent Dan for operation of Erie (Barge) Canal. Records of discharge since Oct. 1, 1925, include small diversion Just above station for Cohoes water supply but do not include diversion through 

lock 6 at Crescent Dam (published herein). During canal navigation season, water is 

received from Black River basin through Black River Canal flowing south (s3e p. 66 ), 

and Lansing Kill, and from Chenango River basin through Oriskany Creek feeler. Water 

is diverted into (or may occasionally be received from) Oswego River basin through 

summit level of Erie (Barge) Canal between New London and Utlca. Since 1934, 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. Plow partly 

regulated by Delta and Hinckley Reservoirs for period of record and since 1926 by Schoharie Reservoir (combined capacity, 8,738,000,000 cu ft). Extensive diurnal fluctuation caused by School Street powerplant and, prior to 1925, at low flows only, by 

locks and dams on Erie (Barge) Canal.

HUDSON RIVER BASIN 77

3580. 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 1960.

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

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

bypass channel at datum 10.59 ft higher.

Average discharge.--14 years, 13,930 cfs.

Extremes.--Maximum discharge during year 134,900 cfs Apr. 5 (gage height, 24.41 ft); minimum daily discharge, 1,570 cfs Sept. 5; minimum gage height, 14.75 ft Sept. 6.

1946-60: Maximum discharge, 181,000 cfs Dec. 31, 1948 (gage height, 27.0") 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. 23, 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 b;r Corps of 

Engineers.

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

Records include flow over spillway, through wheels, and through lock. Records do not 

include flow in bypass channel (a diversion from Mohawk River entering Hudson River 

l-j miles downstream). Average flow in bypass channel during current year wa3 11 cfs. 

Flow appreciably regulated by Sacandaga Reservoir (see p 50 ), Indian Lake (see p.43), 

and Delta, Hickley, and Schoharie Reservoirs (combined capacity, 8,738,000,000 cu ft). 

Diurnal fluctuation caused by powerplants above station. Diversion above station for 

water supply of city of New York (see records for Mohawk River at Cohoes and Schoharie 

Creek at Burtonsville). During canal navigation season, water is received f'-om Black 

River basin through Black River Canal, flowing south (see p. 66) and Lansing Kill, and 

from Chenango River basin through Or-iskany Creek feeder. Water is diverted into (or 

may occasionally be received from) Oswego River basin through summit level of Erie 

(Barge) Canal between New London and Utica. Water is diverted into St. Lawrence River 

basin through Glens Falls feeder, Bond Creek (see p. 53,54), and Champlain (Barge) Canal 

and occasionally may be received from that basin through summit level of Champlain 

(Barge) Canal at Dunham Basin. Records of water temperatures for the water year 1960 

are given in WSP 1741.

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

Commission project from ratings developed by the Geological Survey.

Discharge, In cubic feet per second, water year October 1959 to September 1960

to July 1, 1957, staff gage at same site and datum.

Average discharge .--11 years (1924-32, 1957-60), 158 cfs.

Extremes .--Maximum discharge during year, 4,480 cfs Sept. 12 (gage height, 7.89 ft); minimum, 9.3 cfs May 28 (gage height, 0.56 ft), result of regulation.

1924-32, 1957-60: Maximum discharge, 7,350 cfs Sept. 1, 1927 (gage height, 10.5 ft, 

from graph based on gage readings), from rating curve extended above 2,300 cfs on 

basis of slope-area measurement at gage height 8.07 ft, an estimated discharge in 1952 

based on floodmarks at Pine Bush and indirect measurements on Shawangunk Kill at 

Winterton and at Ganahgote, and an estimated discharge in 1955 based on a floodmark at 

Pine Bush and indirect measurements at Ganahgote; minimum, 2.3 cfs July 21, 22, 1957; 

minimum gage height, 0.37 ft Aug. 5, 1930.

Floods of Aug. 19 and Oct. 16, 1955, reached a stage of about 12.5 ft, from floodmarks (discharge, 9,700 cfs, based on unit runoff at Ganahgote for each flood). Flood 

of June 1, 1952, reached a stage of about 11.0 ft, from floodmarks (discharge, 7,200 

ofs, based on unit runoff at Winterton and at Ganahgote).

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

which are fair. Slight regulation at low flow by dams above station.

120 HACKENSACK RIVER BASIN

3775. Pascack Brook at Westwood, N. J.

Location.--Lat 40°59'33", long 74"01'19", on right bank 75 ft upstream fro-n Harrington 

Avenue in Westwood, Bergen County, 500 ft downstream from Musquapsink Creek, and 

2.3 miles upstream from mouth.

Drainage area. 29.6 sq mi.

Records available. September 1934 to September 1960.

Gage. Water-stage recorder and concrete control. Datum of gage is 28.62 ft above mean 

sea level, datum of 1929.

Average discharge. 26 years, 52.8 cfs (unadjusted).

Extremes.--Maximum discharge during year, 976 cfs Sept. 12 (gage height, 5.09 ft); minimum daily, 24 cfs June 9, 10, 27, July 24-26.

1934-60: Maximum discharge, 1,610 cfs July 23, 1945 (gage height, 6.76 ft); minimum, 5.8 cfs Oct. 21, 1949, minimum daily, 6.1 cfs Oct. 21-25, Nov. 10, 11, 1949.

Remarks. --Records excellent. Plow regulated by Woodcliff Lake 3 miles abo-re station 

(see p. 122 ). Water diverted for municipal supply by Spring Valley Water Works and 

Supply Co. by pumpage from well fields in headwater area of Pascack Brook in vicinity 

of Spring Valley, N. Y., and by Park Ridge Water Department by pumping from wells 

above Hoodcliff Lake probably reduces flow past this station.

Cooperation.--Gage-height record collected in cooperation with Hackensack Water Co.

Revisions (water years) .--WSP 851: 1937. Monthly and yearly figures of discharge per 

square mile and runoff in inches, published in water-supply papers for 1934-53 may 

not represent natural flow because of uncertainty in the adjustments fo" the effect 

of regulation, evaporation, and pumpage from well fields above station, and should 

not be used.

b Stage-discharge relation affected by Ice.
PASSAIC RIVER BASIN 125

3805. Rockaway River above reservoir, at Boonton, N. J.

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

County, 1.8 miles upstream from Boonton Reservoir Dam.

Drainage area.--116 sq mi.

Records available.--October 1937 to September 1960. Monthly discharge only for October 

1937, published in WSP 1302.

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

sea level (New Jersey Geological Survey bench mark).

Average discharge. 23 years, 215 cfs (unadjusted).

Extremes.--Maximum discharge during year, 1,690 cfs Apr. 5, Sept. 13; maximum gage height, 

4.88 ft Sept. 13; minimum daily discharge, 47 cfs July 25, 26.

1937-60: 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 excellent prior to Apr. 6. good Apr. 6 to July 26, and fair thereafter. 

Plow regulated by Splitrock Reservoir 14§ miles above station (see p. 152). Town of 

Boonton diverts water for municipal supply from Taylortown Reservoir on Stony Brook 

(capacity, 75,000,000 gal) and by pumping from wells In vicinity of Boonton. The mean 

diversion during the water year from Taylortown Reservoir was 0.2 cfs. Rockaway 

Valley trunk sewer bypasses the station (see Remarks paragraph for station at Rockaway 

River below reservoir).

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

Revisions.--Monthly and yearly figures of discharge per square mile and runoff in inches, 

previously published in water-supply papers for 1937-53, may not represent natural 

flow because of uncertainty In the adjustments for the effect of regulation and diversion above station.

126 PASSAIC RIVER BASIN

3810. Rookaway 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 to December 1903; January, February 1904 (gage heights only); 

January 1906 to September 1925 (monthly discharge only, published in V'SP 1302; records 

published in previous water-supply papers were adjusted for storage ard diversion); 

October 1925 to September 1930; October 1930 to September 1950 (monthly discharge only, 

published in WSP 1302; figures of daily discharge published in previous water-supply 

papers not equivalent because \of inflow from sewage effluent); October 1950 to September 

1954 in Special Report 16 of Nfew Jersey Department of Conservation anc1 Economic Development (figures of daily discharge published in previous water-supply papers not equivalent because of inflow from sewage effluent); October 1954 to September 1960. Published 

as "near Boonton" 1903-4 and as "at Boonton" 1906-37.

Gage.--Water-stage recorder. Concrete control since Nov. 5, 1936. Datuir of gage is 195.68 

ft above mean sea level (New Jersey Geological Survey bench mark). Msr. 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.--54 years (1906-60), 138 cfs (adjusted for sewage effluent since October 1930).

Extremes.--Maximum discharge during year, 1,730 cfs Sept. 13 (gage height, 5.82 ft); minimum daily, 0.8 cfs Oct. 3-6.

1903-4, 1906-60: Maximum daily discharge, 7,560 cfs Oct. 10, 1903; practically no 

flow for many days.

Remarks.--Records excellent except those below 10 cfs, which are good. Fecords given herein represent flow over control only. Flow regulated by Boonton Reservoir 2,000 ft above 

station and by Splitrock Reservoir 16^ miles above station (see p. 152). Sewage effluent from Rockaway Valley trunk sewer is discharged to Rockaway River fOO ft below station. Most of the water for sewage effluent is diverted by water departments or companies by pumping from wells in vicinity of Wharton, Dover, Denville, and Boonton. 

Water diverted from Boonton Reservoir for municipal supply for Jersey City (see p. 152).

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

furnished by Jersey City.

Revisions.--Monthly and yearly figures of discharge per square mile and runoff in inches, 

previously published in water-supply papers for 1906-53 may not represent natural flow 

because of uncertainty in the adjustments for effect of regulation, diversion, and 

evaporation.

1903 (gage height, 3.85 ft); no flow over dam during several months of most years.

Remarks . Records given herein represent flow over intake dam only. Water diverted above 

intake dam for municipal supply of Newark (see p. 154). Plow regulated by Oak Ridge, 

Canlstear, Clinton Reservoirs, and Echo Lake (see p. 152).

Cooperation. Records, in millions of gallons, furnished by Department of Public Affairs 

Division of Water, Newark. '

Revls Ions . Monthly and yearly figures of discharge per square mile and rvnoff In inches 

previously published in water-supply papers for 1925-53 may not represent natural flow 

because of uncertainty In the adjustments for effect of regulation and evaporation

ft above mean sea level, datum of 1929. Mar. 7, 1903, to Dec. 31, 1904, staff gage at 

main spillway at different datum.

Average discharge.--21 years, 502 cfs (unadjusted).

Extremes. Maximum discharge during year, 5,740 cfs Apr. 6 (gage height, 11.93 ft, at 

Pequannock); minimum daily, 92 cfs July 26.

1903-4, 1940-60: Maximum discharge observed, 28,340 cfs Oct. 10, 1903 (gage height, 

14.3 ft, site and datum then in use) , by computation of peak flow over dam; no flow 

Aug. 18-20, 1904.

Remarks.--Records good. Water diverted from reservoirs on Pequannock and Wanaque Rivers 

for municipal supply (see p. 154). Flow regulated by Oak Ridge, Canistear, Clinton, 

and Echo Lake Reservoirs on Pequannock River and by Greenwood Lake and Wanaque Reservoir on Wanaque River (see p.152,153 ). Some diurnal fluctuations at low flow caused 

by powerplant on Wanaque River.

Revisions (water years). WSP 1202: 1945(M). Monthly and annual figures of discharge per 

square mile and runoff in inches, 1940-53, may not represent natural fow because of 

uncertainty in the adjustments for effect of regulation, diversion, and evaporation, 

and should not be used.

PASSAIC RIVER BASIN 

3895. Passaic River at Little Falls, N. J.

141

Location. Lat 40°53'05", long 74 0 13'35", on left bank 0.6 mile downstream from Beatties 

Dam in Little Falls, Passaic County, and 1 mile upstream from Peckman River.

Drainage area. 762 sq mi.

Records available.--September 1897 to September 1960. Monthly discharge only for September 1897 to September 1925, published in WSP 1302. Published as "at Paterson" 

September 1897 to September 1955.

Gage. Water-stage recorder. Datum of gage is 120.00 ft above mean sea level (Passaic 

Valley Water Commission bench mark). Prior to Jan. 8, 1933, staff gage and Jan. 8, 

1933, to Sept. 30, 1955, water-stage recorder, at site 3.7 miles downstream at mean 

sea level datum (New Jersey Geological Survey bench mark).

Average discharge. 63 years, 1,202 cfs (unadjusted).

Extremes. Maximum discharge during year, 7,140 cfs Apr. 7 (gage height, 7.15 f;); minimum daily, 95 cfs July 25, 26.

1897-1960: Maximum dally discharge, 28,000 cfs Oct. 10, 1903; no flow July 3-5, 

1904, July 16, 23, 1905.

Remarks.--Records excellent. Diurnal fluctuation at medium and low flow caused by 

hydroelectric plant at Beatties Dam. Flow regulated by reservoirs in Rockaway, 

Pequannock, and Wanaque River basins (see p. 152). Large diversions for municipal 

supply from Passaic River above Beatties Dam, and from Rockaway, Pequannock, and 

Wanaque Rivers (see p. 154). In addition, the Commonwealth Water Co. diverts small 

amounts from Canoe Brook near Summit (average for 1960 was 4.3 cfs) and from Passaic 

River (average for 1960 was 7..6 cfs); that company and the city of East Orange also 

divert water for municipal supply by pumping from wells.

Cooperation. Records collected in cooperation with Passaic Valley Water Commission.

Revisions (water years). Monthly and yearly figures of discharge per square mile and

runoff in inches, previously published in water-supply papers for 1926-53, may not represent natural flow because of the uncertainty in the adjustments for the effect of 

regulation and diversion above station.

ELIZABETH RIVER BASIN 155

3935. Elizabeth River at Elizabeth, N. J.

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

Avenue Bridge in Elizabeth, Union County, and 3.3 miles upstream from mouth.

Drainage area.--30.2 sq mi, of which 

the station.

!.2 sq mi contributes to a storm sewer which bypasses

Records available. October 1921 to September 1960.

Gage.--Water-stage recorder and concrete control. Datum of gage is 5.23 ft abov? 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.--39 years, 23.6 cfs (unadjusted).

Extremes. Maximum discharge during year, 2,130 cfs Sept. 12 (gage height, 12.42 ft, from 

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

contracted-opening measurements at gage heights 13.19, 13.88, and 15.02 ft; minimum 

daily, 7.7 cfs Oct. 18, Nov. 22, Sept. 5.

1921-60: Maximum discharge, 2,720 cfs July 23, 1938, from rating curve extended 

above 1,100 cfs on basis of contracted-opening measurements of peak flow at gage height 

13.05 ft; 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 of no gage-height record, which are fair. 

Diversion by pumpage from Hammock well field, in Union, for municipal supply by Elizabe thtown Water Co. probably reduces the flow past the station. Occasional regulation 

by Drsino Lake.

Revisions (water years). WSP 1552: Drainage area, 1922-23, 1927-29(M), 1932, 1933-34 (M), 

1938(P), 1942(M) , 1944(P), 1945(M), 1948(P), 1952-53(M). Monthly and yearly adjusted 

figures of discharge per square mile and runoff in inches, previously publish?d 

1921-53, may not represent natural flow because of uncertainty In adjustments for 

effect of diversion and pumpage from wells above station and should not be ussd.

Note. No gage-height record Jan. 27 to Mar. 7, June 24 to July 29; discharge estimated on basis 

weather records and records for Second River at Belleville and Railway River near Springfield.
156 RAHWAY RIVER BASIN

3945. Rahway River near Springfield, N. J.

Location. Lat 40°41 1 11", long 74"18 I 44", on left bank 50 ft downstream from bridge on 

U.S. Highway 22, 100 ft downstream from Pope Brook, and 1? miles south of Springfield, 

Union County.

Drainage area. 25.5 sq mi.

Records available. July 1938 to September 1960.

Gage.--Water-stage recorder and concrete control. Datum of gage is 66.17 ft above mean 

sea level, datum of 1929.

Average discharge. 22 years, 26.6 cfs (unadjusted).

Extremes. Maximum discharge during year, 911 cfs Sept. 12 (gage height, 5.27 ft); minimum 

daily, 3.3 cfs July 26.

1938-60: Maximum discharge, 1,940 cfs July 23, 1938 (gage height, 7.41 ft), from 

rating curve extended above 900 cfs on basis of contracted-opening measurement of peak 

flow; minimum, 0.9 cfs Sept. 7-9, 11, 12, 1944, Oct. 4, 5, 1957 (gage height, 1.18 ft).

Remarks. Records excellent. Water for municipal supply diverted from river by city of 

Orange. The flow past this station is affected by diversions by pumpage from wells by 

Orange, South Orange, Short Hills Water Co., and Springfield station of Elizabethtown 

Water Co.

Revisions (water years).--WSP 1622: 1945. Monthly and yearly adjusted figures of discharge per square mile and runoff in inches, previously published in 1938-53, may not 

represent natural flow because of uncertainty in the adjustments for the effect of regulation, diversion, and pumpage from wells above station and should not be uaed.

170 RARITAN RIVER BASIN

4020. Millstone River at Blackwells Mills, H. J.

Location. Lat 40°28'30", long 74°34 I 34", on left bank 30 ft downstream from highway

bridge at Blackwells Mills, Somerset County, and 0.3 mile downstream from Six Mile Run.

Drainage area.--258 sq mi.

Records available.--June 1903 to December 1904 (gage heights and discharge measurements 

only), August 1921 to September 1960. Published as "at Millstone" 1903-4.

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

26.97 ft above mean sea level, datum of 1929. June 27, 1903, to Dec. 31, 1904, staff 

gage at bridge 2.0 miles downstream at Millstone at different datum. Aug. 4, 1921, to 

Aug. 16, 1928, staff gage at present site and datum.

Average discharge. 39 years (1921-60), 365 cfs.

Extremes. Maximum discharge during year, 8,030 cfs Sept. 13 (gage height, 11.07 ft); minimum, 38 cfs Oct. 1 (gage height, 1.39 ft).

1921-60: Maximum discharge, 18,300 cfs Sept. 21, 1938 (gage height, 15.29 ft, from 

floodmark), from rating curve extended above 6,900 cfs on basis of slope-area measurement of peak flow; minimum, about 5 cfs Sept. 16, 1923.

Remarks.--Records good. Inflow to and losses from Delaware & Raritan Canfl above station. 

Plow slightly regulated by Lake Carnegie (capacity, 310,000,000 gal) ard by several 

smaller reservoirs (capacity, 49,800,000 gal).

Revisions [water years).--MSP 1552: 1924-25(M), 1926. Monthly and yearly figures of 

discharge per square mile and runoff in inches, previously published in 1938-43, 

1945-57, may be subject to considerable error because of diversion to cr inflow from 

Delaware & Raritan Canal, and storage and evaporation in Lake Carnegie and should not be 

used.

flow (a peak overflow of about 4,400 cfs bypassed gage, based on computation of flow 

over Lower Seeley Dam 4.4 miles upstream by New Jersey Department of Conservation and 

Economic Development); no flow at times.

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

which are fair. Water diverted from Baltusrol well field by Commonwealth Water Co. and 

from wells in vicinity of Mountainside and Scotch Plains by Plainfield-Onion Water Co. 

for municipal supply and from private and industrial wells in Plainfield and vicinity.

During extreme high stages considerable overflow above gage from Green Brook basin to 

adjacent Cedar Brook basin, which returns to Green Brook 5.1 miles below gage by way of 

Bound Brook.

a No gage-height record; discharge estimated on basis of records for Matchaponix Bpoolt at Spots 

wood and South River at Old Bridge, 

e Waste gate open.
180 RARITAN RIVER BASIN

4055. South River at Old Bridge, N. J.

Location. Lat 40°24 1 22", long 74°22'08", on right abutment of Duhernal Dsm, 0.6 mile 

south of Old Bridge, Middlesex County, 2.3 miles upstream from Deep Rur, and 9.1 miles 

upstream from mouth.

Drainage area.. 94.6 sq mi.

Records available. August 1939 to September 1960.

Gage. Water-stage recorder above concrete dam. Datum of gage is at mean sea level, 

3atum of 1929.

Average discharge. 21 years, 138 cfs (unadjusted).

Extremes. Maximum discharge during year, 2,430 cfs Sept. 13 (elevation, 11.20 ft), from 

rating curve extended above 770 cfs on basis of laboratory rating; minimum daily, 

27 cfs Oct. 1.

1939-60: Maximum discharge, 4,250 cfs Sept. 15, 1944 (elevation, 11.71 ft), from 

rating curve extended above 770 cfs on basis of laboratory rating; minimum daily, 

2.0 cfs Aug. 14, 1957.

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

Records given herein include flow over spillway and direct diversion from pond for 

dilution of industrial wastes in sewer which discharges into river Just below dam. 

The flow past this station is affected by pumpage from well fields for industrial use 

by Duhernal Water Co. and Peter J. Schweitzer Co. Some regulation by luhernal Lake 

(capacity, 138,000,000 gal).

Cooperation. Water-stage recorder inspected and record of diversion to sewer furnished 

by Duhernal Water Co.

Revisions. Monthly and yearly adjusted figures of discharge per square mile and runoff 

in inches, previously published in water-supply papers for 1939-53, may not represent 

natural flow because of uncertainty in the adjustments for the effect cf regulation in 

reservoir and pumpage from wells above station and should not be used.

Discharge, in cubic feet per second, water year October 1959 to September 1960

1912-60; Maximum discharge, 53,300 cfs Aug. 24, 1933 (gage height, 20.6C 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, atout 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 

controlled by Pepacton Reservoir (see p. 286). Part of flow diverted for municipal 

supply of city of New York. Remainder of flow (except for conservation releases and 

spill) impounded for release during periods of low flow in the lower Delaware River 

basin, as directed by the Delaware River Master.

Falls Bush Kill, and 2? miles upstream from mouth and Mongaup, Sullivan County.

Drainage area.--202 sq mi.

Records available. August 1939 to September 1960.

Gage. Water-stage recorder. Datum of gage is 625.05 ft above mean sea level (datum of 

Srange and Rockland Utilities, Inc.). Prior to July 6, 1956, water-stage recorders at 

sites 25 ft upstream on Rio tailrace and 200 ft upstream on natural channel, at datum 

4.0 ft higher.

Average discharge. 21 years, 343 cfs (unadjusted).

Extremes. Maximum discharge during year, 1,930 efs Apr. 6 (gage height, 6.18 ft); maximum 

daily, 1,820 cfs Apr. 7; minimum, 17 cfs Jan. 26 (gage height, 0.47 ft).

1939-60: Maximum daily discharge, 12,300 efs Aug. 19, 1955; minimum daily, 6 cfs 

Oct. 1, 1939.

Remarks. Records excellent except those below 100 cfs, which are good, and those for 

periods of no gage-height record, which are fair. Entire flow completely regulated by 

Rio hydroelectric plant except for runoff from about 7 sq mi of drainage area below 

Rio Dam of Orange and Roekland Utilities, Inc., and during periods of spill from Rio 

Reservoir. Flow also regulated by storage in Swinging Bridge, and Toronto Reservoirs, 

and in Cliff Lake (see p. 286) and smaller reservoirs above station.

Drainage area. 3,076 sq mi.

Records available.--October 1904 to September 1960.

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

1929. 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, stfff or 

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

Extremes.--Maximum discharge during year, 71,500 cfs Apr. 4 (gage height, 12.69 ft); minimum, 866 cfs Sept. 4 (gage height, 1.83 ft); minimum daily. 1,100 ofs Sept. 4.

1904-60: Maximum discharge, 233,000 cfs Aug. 19, 1955 (gage height, 23.91 ft, from 

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

slope-area measurement of peak flow; minimum, 175 cfs Sept. 23, 1908 (gage flight, 

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

Maximum discharge previously known, 205,000 cfs Oct. 10, 1903 (gage heigtt, 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 good. Flow regulated by Lake Wallenpaupack, and by Toronto, Cliff Lake, 

and Swinging Bridge Reservoirs (see p. 286) and smaller reservoirs. Large diurnal 

fluctuations at medium and low flow caused by powerplants on tributary streams. Subsequent to September 1954, entire flow from 371 sq mi of drainage area controlled by 

Pepacton Reservoir (see p. 286). Part of flow diverted for municipal supply of city of 

New York. Remainder of flow (except for conservation releases and spill) impounded for 

release during periods of low flow in the lower Delaware River basin, as directed by 

the Delaware River Master. Records of suspended sediment loads for the water year 1960 

are given in WSP 1741.

230 DELAWARE RIVER BASIN

4375. Neversink River at Godeffroy, N. Y.

Location. Lat 41°26 I 30", long 74°36'10", on right bank Just upstream from highway bridge, 

half a mile downstream from Basher Kill, three-quarters of a mile southeast of 

Godeffroy, Orange County, 2 miles south of Cuddebackville, and 8^ miles upstream from 

mouth.

Drainage area.--302 sq mi.

Records available.--August to October 1903, August 3909 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 1960 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 0.98 ft higher. 

Aug. 22, 1909, to Jan. 21, 1910, staff gage and Aug. 1, 1910, to Apr. 30, 1914, chain 

gage, at present datum.

Extremes.--Maximum discharge during year, 5,200 cfs Aug. 19 (gage height, 7.55 ft, backwater from aquatic vegetation); minimum, 102 cfs Oct. 1.

1903, 1909-14, 1937-60: Maximum discharge, 33,000 cfs Aug. 19, 1955 (gage height, 

12.49 ft), from rating curve extended above 11,000 cfs on basis of slo*>e-area aeaSUrement of peak flow; practically no flow several times in July 1911.

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

vegetation, or shifting control, which are fair. Subsequent to June 1953, entire flow 

from 91.8 sq mi of drainage area controlled by Neversink Reservoir (se? p. 287). Part 

of flow diverted for municipal supply of city of New York, Remainder of flow (except 

for conservation releases and spill), impounded for release during periods of low flow 

in the lower Delaware River basin, as directed by the Delaware River Mister. Prior to 

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

Cuddebackville.

Revisions (water years).--WSP 821: Drainage area. WSP 1502: 1951(M).

Average discharge.--21 years (1939-60), 6,408 cfs (unadjusted).

Extremes.--Maximum discharge during year, 74,900 cfs Apr. 5 (gage height, 19.09 ft); minimum, 1,240 cfs Aug. 18 (gage height, 4.67 ft); minimum daily, 1,460 cfs Aug. 18.

1939-60: Maximum discharge, 250,000 cfs Aug. 19, 1955 (gage height, 35.15 ft), from 

rating curve extended above 90,000 cfs on basis of flood-routing study; 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 present rating curve extended above 90,000 cfs).

Remarks.--Records excellent except those for period of ice effect, which are' good. Diurnal fluctuation at medium and low flow caused by power-plants on tributary streams. 

Flow regulated by Lake Wallenpaupack and by Pepacton, Swinging Bridge, Toronto, Cliff 

Lake, and Neversink Reservoirs (see p. 287) and smaller reservoirs. Diversion from 

Pepacton and Neversink Reservoirs (see p. 290).

4560. Musconetcong River near Hackettstown, N. J.

Location. Lat 40°53 I 10", long 74°48'00", on right bank 75 ft upstream from Saxton Falls 

Dam, half a mile upstream from Delaware, Lackawanna and Western Railroad bridge, and 

3 miles northeast of Hackettstown, Warren County.

DrainaKe area.--70.0 sq mi.

Records available. September 1921 to September 1960.

Gage.--Water-stage recorder above concrete dam. Datum of gage is 630.93 ft above mean sea 

level (New Jersey Geological Survey bench mark). Prior to Aug. 21, 1923, staff gage 

and Aug. 21, 1923, to July 19, 1938, water-stage recorder, at site 2,000 ft downstream 

at datum 26.97 ft lower.

Average discharge. 39 years, 121 cfs (unadjusted).

Extremes.--Maximum discharge during year, 867 cfs Sept. 13 (gage height, 2.63 ft); mlnimum daily, 16 cfs July 26.

1921-60: Maximum discharge, 2,170 cfs Aug. 19, 1955 (gage height, 3.97 ft), from 

rating curve extended above 600 cfs by logarithmic plotting; no flow part of Sept. 6, 

1951, Feb. 4, 5, 1957, when water was below spillway, waste gate was closed, and no 

flow through swimming pool.

rhich are fair, 

id gate. Plow

Cooperation.--Water-stage recorder operated by employee of Morris Canal & Banking Co.

Revisions (water years).--WSP 1051: 1944-45. Monthly and yearly figures of discharge 

per square mile and runoff in inches, previously published in water-supply papers for 

1926-53, may not represent natural runoff because of uncertainty in the adjustments 

for the effects of regulation, diversion,and evaporation and should not be used.

Discharge, in cubic feet per second, water year October 1959 to Septemler I960

Flood of Oct. 10, 1903, reached a stage of 35.9 ft, from floodmark (discharge, 

275,000 cfs).

Remarks. Records excellent. Diurnal fluctuation at medium and low flow caused by powerplants on tributary streams. Flow regulated by Lakes Hopatcong and Wallenpaupack and 

by Pepacton, Swinging Bridge, Toronto, Cliff Lake, Neverslnk and Wild Creek Reservoirs 

(see p. 286) and smaller reservoirs. Diversion from Pepacton and Neverslnk Reservoirs 

(see p. 290) and to Delaware Division Canal (see diversion below). Results of discharge measurements, In cubic feet per second, of Delaware Division Canal at Durham 

aqueduct 1 mile south of Rlegelsville, Pa., are given herewith:

Ft abDve mean sea level, datum of 1929.

Extremes.--Maximum discharge during year, 4,860 cfs Sept. 12 (gage height. 8.3 ft, from 

graph based on gage readings); minimum observed, 21 cfs Sept. 7, 8, 9 (gage height, 

0.29 ft) .

1958-60: Maximum discharge, 5,180 cfs July 6, 1958 (gage height, 8.57 ft, from 

floodnark); minimum daily, 19 cfs July 12, 1959.

FlDod of Aug. 9, 1942, reached a stage of 12.49 ft, from floodmark (discharge, 11,900 

cfs, oy slope-area measurement of peak flow).

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

which are fair. The Borough of Downingtown diverted water from a point above station 

for manicipal water supply, equivalent to a mean discharge at station of 0.5 cfs.

4865. Beaverdam Creek near Salisbury, Md.

Location. Lat 38°21'05", long 75"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 1960. 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 bench mark). Prior to Sept. 28, 1938, 

at site on left bank at datum 9.02 ft higher.

Average discharge.--25 years (1929-32, 1938-60), 23.2 cfs.

Extremes. Maximum discharge during year, 214 cfs Sept. 12 (gage height, 11.40 ft); minimum daily, 3.7 cfs Aug. 28-31.

1929-60: 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-watermark 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 ice effect, which are fair, and those 

below 5 cfs, which are poor. Records include flow over spillway plus leakage through 

floodgates. Occasional regulation at low and medium flow caused by mill above station.

upstream from highway bridge at East Sidney, Delaware County, 4 miles upstream from 

mouth, and 4-| miles east of Unadilla.

Drainage area. 102 sq mi (measured by Corps of Engineers).

Records available. November 1949 to September 1952 (monthly elevations and contents), 

October 1952 to September 1960.

Gage.--Water-stage recorder. Datum of gage is at mean sea level (levels by Corps of 

Engineers).

Extremes.--Maximum elevation during year, 1,194.4 ft Apr. 6 (contents, 25,060 acre-ft); 

minimum, 1,115.5 ft Sept. 8, 9 (contents, 62 acre-ft).

1949-60: Maximum elevation, that of Apr. 6, 1960; minimum, 1,115.0 ft Aug. 31, 1953 

(contents, 56 acre-ft).

Remarks. Reservoir is formed by concrete dam and rockfill dike, completed by Corps of 

Engineers in June 1950 for flood control; first used for flood regulation on Mar. 28, 

1950. Usable capacity, 33,550 acre-ft between elevations 1,115.0 ft (sill of conduits) 

and 1,203.0 ft (crest of spillway). Dead storage, 56 acre-ft. Floods are controlled 

by the operation of five gates. Water is stored during high flows and released when 

downstream conditions warrant.

Cooperation.--Capacity curve furnished by Corps of Engineers.

27.30 ft higher.

Average discharge.--20 years, 175 cfs (adjusted).

Extremes. Maximum discharge during year, 4,000 cfs Apr. 7 (gage height, 6.19 ft); minimum, 2.3 cfs Apr. 6 (gage height, 0.49 ft).

1940-60: Maximum discharge, 7,250 cfs Dec. 30, 1942 (gage height, 7.62 ft, site and 

datum then in use), from rating curve extended above 4,000 cfs by logarithmic plotting; 

minimum. 1.2 cfs (result of construction operations) Aug. 13, 14, 17, 1949 (gage height, 

0.32 ft).

Maximum discharge known, 16,700 cfs in July 1935, by computation of flow over dam 

and from floodmarks.

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

which are fair. Since November 1949, flow regulated by East Sidney Reservoir (see 

preceding page).

Extremes.--Maximum discharge during year, 30,400 cfs Apr. 1 (gage height, 12.00 ft); minimum, 144 cfs Oct. 1 (gage height, 2.48 ft, backwater from aquatic vegetation).

1912-60: Maximum discharge, 96,000 cfs July 8, 1935 (gage height, 20.3 ft, from 

floodmarks), from rating curve extended above 32,000 cfs on basis of slope-area measurement of peak flow; minimum, 84 cfs Sept. 19, 25, 1939 (gage height, 2.24 ft).

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

aquatic vegetation, which are fair. Since March 1942, flood flows partly regulated by 

Whltney Point Reservoir (see p. 332).

1929. Prior to Aug. 29, 1956, wire-weight gage and crest-stage gage at site 250 ft upstream at same datum.

Average discharge. 6 years, 13.2 cfs.

Extremes. Maximum discharge during year, 578 cfs Nov. 28 (gage height, 2.91 ft), from 

 rating curve extended above 12 cfs; minimum, 0.2 cfs Oct. 5, 6, Sept. 8-11; minimum gage

height, -0.09 ft July 29, 30.

1954-60: Maximum discharge, 1,240 cfs Oct. 14, 1955 (gage height, 6.77 ft, site then

in use), from rating curve extended above 230 cfs on basis of slope-area measurement of

peak flow; no flow at times.

Remarks. Records good except those above 20 cfs prior to Nov. 28 and those for periods of 

Tce~effect, which are fair. This station is operated as the control station in connection with a study of the effect of comprehensive soil conservation measures on 

streatnflow and suspended sediment loads of Corey Creek. Records of suspended sediment 

loads and water temperatures for the water year 1960 are given in WS? 1741.

350 SUSQUEHANNA RIVER BASIN

5245. Canisteo River below Canacadea Creek, at Hornell, N. Y.

Location. Lat 42°18'5Q", long V7°39'05", on right bank 235 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 mi.

Records available. August 1942 to September 1960.

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

sea level (Corps of Engineers bench mark).

Average discharge.--18 years, 165 cfs.

Extremes.--Maximum discharge during year, 4,490 cfs June 15 (gage height, 8.89 ft); minimum daily, IV cfs Sept. 8.

1942-60: 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 measurement of peak 

flow; minimum, 7.4 cfs Sept. 13, 14, 1955.

Remarks.--Records good except those for periods of ice effect, partly obstructed intake, 

or no gage-height record, which are fair. 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. 345), and, since October 1948, by Almond Reservoir (see p. 348); normal 

regulation insufficient to materially affect figures of monthly runoff.

Cooperation. Records of diversion from Carrington Creek furnished by city of Hornell.

5575. South Bald Eagle Creek at Tyrone, Pa.

Location. Lat 40°41'00", long 78°14>05", on left bank 0.2 mile upstream from plant of 

West Virginia Pulp and Paper Co., at Tyrone, Blair County, 0.2 mile upstream from 

Laurel Run, and 1.3 miles upstream from mouth.

Drainage area.--44.1 sq mi.

Records available.--October 1944 to September 1960.

Gage.--Water-stage recorder. Datum of gage is 921.80 ft above mean sea level, datum of 

1929. Oct. 1, 1944, to Nov. 15, 1950, water-stage recorder and Nov. 16, 1950, to 

Nov. 30, 1952, wire-weight gage and high-water staff gage, at site half a mile downstream at datum 17.99 ft lower.

Average discharge.--16 years, 80.8 cfs (adjusted for diversion from October 1950 to November 1952).

Extremes. Maximum discharge during year, 1,550 cfs Mar. 31 (gage height, 4.27 ft); minimum, 3.5 cfs Oct. 4, 5 (gage height, 0.26 ft).

1944-60: Maximum discharge, 5,140 cfs Nov. 25, 1950 (gage height, 7.5 ft, from 

floodmarks, at site and datum then in use), from rating curve extended above 2,100 cfs 

on basis of contracted-opening measurement of peak flow; minimum, 2.2 cfs Sept. 26, 27, 

1959 (gage height, 0.20 ft).

Maximum stage known, about 15 ft Mar. 17 or 18, 1936 (site and datum in use prior to 

Dec. 1, 1952).

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

which are fair. Prior to Oct. 1, 1950, daily discharges were affected by diversion 

from the basin of a small quantity of water for boiler feed makeup for West Virginia 

Pulp and Paper Co. From Oct. 1, 1950, to Nov. 30, 1952, in addition to the effects of 

above diversion, daily discharges were affected by diversion into the basin, by West 

Virginia Pulp and Paper Co., of water from ground-water sources. Daily discharges 

subsequent to Nov. 30, 1952, are not affected by diversion.

466 POTOMAC RIVER BASIN

6030. North Branch Potomac River near Cumberland, Md.

Location.--Lat 39°37'16", long 78°46'24", on left bank at downstream side of Wlley 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 1960. Gage-height records collected at various 

sites about 2 miles upstream from September 1901 to December 1932, and thereafter at 

present site, are contained in reports of U.S. Weather Bureau.

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

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

Average discharge.--31 years, 1,213 cfs (unadjusted).

Extremes. Maximum discharge during year, 22,200 cfs Mar. 31, May 8; maximum gage height, 

17.36 ft May 8; minimum discharge, 135 cfs Aug. 29.

1929-60: 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 measurement 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 good except those for periods of Telemark readings, which are fair. Regulation by reservoir on Stony River, about 79 miles above station (see p. 456), and 

since December 1950, by reservoir on Savage River (see p. 459). Prior to July 1957, 

small amount of inflow from industrial wastes and sewage from city o p Cumberland from 

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

Chesapeake and Ohio Canal prior to 1935.

Records available. October 1938 to September 1960.

Gage.--Water-stage recorder. Datum of gage is 487.88 ft above mean sea level (Corps of 

Engineers bench mark). Prior to Mar. 25, 1939, wire-weight gage at bridge 250 ft downstream at same datum.

Average discharge. 22 years, 3,107 cfs.

Extremes. Maximum discharge during year, 62,300 cfs May 9 (gage height, 28.27 ft); minimum, 318 cfs Aug. 29.

1938-60: Maximum discharge, 111,000 cfs Oct. 16, 1942 (gage height, 38.36 ft); minimum, 189 cfs Sept. 28, 29, 1959.

Maximum stage known, 54.0 ft Mar. 18, 1936 (discharge, 240,000 cfs, from rating 

curve extended above 85,000 cfs on basis of slope-area measurement of peak flow at site 

5 miles upstream at Okonoko, W. Va.).

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

fair. Low flow affected by Stony River Reservoir (see p. 456) and, since December 

1950, by Savage River Reservoir (see p. 459).

staff gage a few hundred feet downstream from Middle Bridge, 1.2 miles upstream at 

datum about 12 ft higher. Aug. 21, 1928, to July 13, 1933, staff gage at Burnside 

Bridge at same datum.

Average discharge.--37 years (1897-1903, 1904-5, 1930-60), 268 cfs (adjusted for inflow 

since 1930).

Extremes.--Maximum discharge during year, 2,660 cfs June 18 (gage height, 7.14 ft); minimum, 35 cfs Oct. 13; minimum daily, 61 cfs Oct. 13.

1928-60: Maximum discharge, 12,600 cfs July 20, 1956 (gage height, 16.73 ft), from 

rating curve extended above 4,300 cfs on basis of contracted-opening measurement of 

peak flow; minimum, 9.4 cfs Nov. 22, 1957, result of regulation caused by construction 

work above station; minimum daily, 50 cfs Sept. 29, 1930, Feb. 1, Oct. 4, 1931.

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

Flow slightly regulated by powerplant above station. Regulation greater prior to 1936. 

Since 1928, records include pumpage from Fotomac River for municipal srpply of 

Hagerstown. This water later enters Antietam Creek above station as sewage.

Catoctin Creek (Virginia) and 6 miles upstream from Monocacy River.

Drainage area. 9,651 sq mi.

Records available .--February 1895 to September 1960.

Gage. Water-stage recorder. Datum of gage is 200.54 ft above mean sea level, adjustment 

of 1912. Prior to Sept. 2, 1902, wire-weight gage on downstream side of bridge at 

datum about 0.45 ft higher. Sept. 2, 1902, to Oct. 28, 1929, chain gage at same site 

at present datum.

Average discharge. 65 years, 9,248 cfs.

Extremes. Maximum discharge during year, 124,000 cfs May 10 (gage height, 20.28 ft); minimum, 1,130 cfs Oct. 1 (gage height, 0.71 ft).

1895-1960: 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 measurement 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 good except those for periods of ice effect, which are fair. Low flow 

aPTected slightly since 1913 by Stony River Reservoir (see p. 456) and since December 

1950 by Savage River Reservoir (see p. 459). Records of water temperatures for the 

water year 1960 are given in WSP 1741.

6452. Watts Branch at Rockville, Md.

Note. Records for the 1960 water year have been withheld pending better definition of 

the"sHge-discharge relation. They will be published in a subsequent annurl report.

6465. Potomac River near Washington, D. C.

Location. Lat 38°S7'36", long 77°08'33", on right bank 1 mile upstream from Little Palls 

Dam, l£ miles northeast of Langley, Fairfax County, Va., 2 miles upstream from District of Columbia boundary line, and 2-| miles upstream from Chain Bridge.

Drainage area. 11,560 sq mi.

Records available. March 1930 to September 1960.

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.--30 years, 11,100 cfs (adjusted for diversions).

Extremes.--Maximum discharge during year, 124,000 cfs May 10 (gage height, 13.66 ft); minimum, 1,030 cfs Oct. 1.

1930-60: 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 Palls for 

water supply).

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

1936.

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

at Great Falls through aqueducts, and since June 1959, from gage pool at Little Falls. 

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

Stony River Reservoir (see p. 456) and since December 1950, by Savage River Reservoir 

(see p. 459).

Average discharge. 5 years, 28.7 cfs.

Extremes. Maximum discharge during year, 1,300 cfs Feb. 18, Apr. 5; maximum gage height, 

5768 ft Apr. 5, in gage well; minimum discharge, 2.4 cfs Oct. 26; minimum gage height, 

1.89 ft July 26.

1955-60: Maximum discharge, 7,620 cfs Aug. 12, 1955 (gage height, 9.95 ft in gage 

well), from rating curve extended above 1,500 cfs on basis of logarithmic plotting and 

a slope-area measurement at 7.93 ft; minimum, 1.1 cfs Aug. 15, 1957; minimum gage 

height, that of July 26, 1960.

Flood of May 5, 1953, reached a stage of 11.9 ft, from floodmark.

Remarks. Records fair except those for periods of ice effect and those below 5.0 cfs, 

which are poor. Some regulation at low and high flow by Lake Barcroft, formerly 

Alexandria Reservoir, on Holmes Run 3.6 miles upstream. Some flow diverted into basin 

at low flow from unknown source.

Discharge measurement made on this day. 

a No gage-height record) discharge estimated on basis of records for station near Bowling Oreen 

(Virginia Division of Water Resources).
DISCHARGE AT PARTIAL-RECORD STATIONS AND MISCELLANEOUS SITES 529

As the number of streams on which streamflow information is.likely to be desired far 

exceeds the number of stream-gaging stations feasible to operate at one time, the Geological Survey collects limited streamflow data at sites other than stream-gaging stations. 

When limited streamflow data are collected on a systematic basis over a period of years 

for use in hydrologic analyses, the site at which the data are collected is called a 

partial-record station. Data collected at these partial-record stations are usable in 

low-flow or floodflow analyses, depending on the type of data collected. In addition, 

discharge measurements are made at other sites not included in the partial-record program. 

These measurements are generally made in times of drought or flood to give better areal 

coverage to those events. Those measurements and others collected for some special reason 

are called measurements at miscellaneous sites.

Records collected at partial-record stations are presented in two tables. The first is 

a table of discharge measurements at low-flow partial-record stations and the second is a 

table of annual maximum stage and discharge at crest-stage stations. Discharge measurements made at miscellaneous sites for both low flow and high flow are given in a third 

table.

Low-flow partial-record stations

Measurements of streamflow in the area covered by this report made at low-flow partialrecord 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. These 

measurements, when correlated with the simultaneous discharge of a nearby stream where continuous records available, will give a picture of the low-flow potentiality of stream. The 

column headed "Period of record" shows the water years in which measurements were made at 

the same, or practically the same, site.

DISCHARGE AT PARTIAL-RECORD STATIONS AND MISCELLANEOUS SITES 547

Crest-stage partial-record stations

The following table contains annual maximum discharges for crest-stage stations A 

crest-stage gage is a device which will register the peak stage occurring between inspections of the gage. A stage-discharge relation for each gage is developed from discharge 

measurements made by indirect measurements of peak flow or by current meter. The date of 

the maximum discharge is not always certain but is usually determined by comparison with 

nearby continuous-rlcord stations, weather records, or local inquiry Only the maximum 

discharge for each water year is given. Information on some lower floods may have been 

obtained but is not published herein. The years given in the period of record represent 

water years for which the annual maximum has been determined.
