SCOPE OF WORK

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

year ending September 30, 1957. 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 13,750 gaging stations in the 48 States and at many others in the Territories of Alaska and Hawaii. On September 30, 1957, the Geological Survey and cooperating 

organizations were maintaining 7,030 gaging stations, including those in Alaska and Hawaii. 

Discharge measurements only were made at many other points in the 1957 water year. 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records of discharge prior to publication, and other unpublished data concerning the 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, 1957, PART 1-B

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

published reports.

DOWNSTREAM ORDER OP LISTING GAGING STATIONS

Beginning with the series of reports for the water year ending September 30, 19S1, 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 sta- ~ 

tion are lisbed 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, 1957, 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 

dally records Is not changed.

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

rating table, and a table showing the dally 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 1957 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 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 daturas 

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 dally 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 nonrecordlng gage read at the time of the crest.
EXPLANATION OF DATA 7

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.

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, 1957, 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 published each year for all reservoirs for which records are published on a daily 

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

Discharge measurements and determinations of peak flows made at sites other than gaging 

stations are listed at the end of each report.

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 quality-of-water records collected at gaging stations on a regular basis and published in the quality-of-water reports. At many other 

gaging stations quality-of-water data are obtained at irregular intervals and published 

as "miscellaneous analyses" in quality-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.

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.
PUBLICATIONS 9

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, figures of 

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

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

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

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

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

comparison with the observed discharge.

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.

beginning In 1941, from Z areas about 3.5 acres each near College Park, Md.j and beginning In 1951, 

from 4 areas, 30 to 1,570 acres, In Dutchess County, N. Y.

HYDROLOGIC CONDITIONS

During the 1957 water year streamflow ranges from slightly above median in central 

Pennsylvania to about 30 percent below median in parts of Maryland and New York. Early 

November floods in Delaware, Maryland, southern New Jersey, and south-central Pennsylvania 

resulted in maximum discharges of record at a few short-term gaging stations. Cocolamus 

Creek near Millerstown, Pa., where records are continuous since 1930, had a record peak. 

Streamflow declined rapidly during July to September and remained deficient throughout the 

area. The gaging station on Great Egg Harbor River at Folsom, N. J., had record-low 

monthly mean discharges for July and August; the minimum flow in 32 years of record occurred Sept. 6. Potomac River at Paw Paw, W. Va., had record-low monthly mean discharge 

for August, and the daily discharge Sept. 8 was the lowest in 20 years of record. On 

Sept. 8, 9, Cacapon River near Great Cacapon, W. Va., had the lowest discharge in 34 years 

of record. For three long-term gaging stations in the area covered by this report, a comparison of the monthly and yearly mean discharge for the 1957 water year with the median 

discharge for the period 1921-45 is shown in figure 3 on the following page.

Cedar Swamp Creek at Glen Cove, N. Y.

Location. Lat 40°51'45", long 73°38'05", on right bank Just downstream from highway bridge 

at 8- by 10-foot concrete culvert outlet at pond In Pratt Park, 1 block west of post 

office, Glen Cove, Nassau County.

Drainage area.--About 11 sq ml.

Records available. October 1938 to September 1957.

Gage.--Water-stage recorder and concrete control. Datum of gage Is 15.93 ft above mean 

sea level, adjustment of 1912. Prior to Sept. 10, 1957, at same site at datum 0.06 ft 

lower.

Average discharge. 19 years, 7.40 cfs.

Extremes.--Maximum discharge during year, 1,010 Cfs May 14 (gage height, 5.548 ft), from 

rating curve extended above 220 cfs by logarithmic plotting; minimum, 4.04 cfs July 22; 

minimum gage height, 0.672 ft June 18.

1938-57: Maximum discharge, 1,040 cfs Aug. 12, 1955 (gage height, 5.62 ft), from 

rating curve extended above 230 ci's by logarithmic plotting; minimum, 3.34 cfs Nov. 15, 

1946 (gage height, 0.583 ft), flow reduced temporarily, cause unknown.

Remarks.--Records excellent except those for periods of shifting control, backwater from 

debris, or no gage-height 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 569 for results of discharge measurements of 

Long Island streams at sites other than regular gaging stations.

22 STKEAMS ON LONG ISLAND

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

Location.--Lat 40°51 I 25", long 73°27'50", on left bank 270 ft upstream from State Hlghway 25A, at Cold Spring Harbor State Pish Hatchery, Nassau County, and 1 mile southwest 

of village of Cold Spring Harbor, Suffolk County.

Drainage area. About 7.3 sq ml.

Records available. July 1950 to September 1957.

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

level, datum of 1929.

Average discharge. 7 years, 2.48 cfs (unadjusted).

Extremes. Maximum discharge during year, 16.9 cfs May 4 (gage height, 0.616 ft); maximum 

gage height, 1.217 ft Jan. 16 (backwater from high tide); minimum discharge, 0.98 cfs 

May 10 (gage height, 0.157 ft).

1950-57: Maximum discharge, 108 cfs Sept. 11, 1954 (gage height, 1.332 ft, backwater from aquatic vegetation), from rating curve extended above 21 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 no 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 569 for results of discharge measurements of Long Island streams at sites 

other than regular gaging stations.

Smithtown Branch.

Drainage area. About 27 sq mi.

Records available. October 1943 to September 1957.

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

level, datum of 1929.

Average discharge. 14 years, 41.76 cfs.

Extremes.--Maximum discharge during year, 75.5 cfs Apr. 5 (gage height, 0.902 ft); minimum, 

28.0"ofs July 23 (gage height, 0.600 ft); minimum daily, 30.7 cfs July 24.

1943-57: Maximum discharge, 324 cfs Oct. 15, 1955 (gage height, 1.96 ft), from 

rating curve extended above 128 cfs by logarithmic plotting; minimum, 18.6 cfs Feb. 9, 

1951 (gage height, 0.460 ft); minimum daily, 20.0 cfs Oct. 6, 1947.

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

or backwater from aquatic vegetation, 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 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. See page 569 for results of discharge measurements of Long Island 

streams at sites other than regular gaging stations.

li'evel, datum of 1929. 

Average discharge.--15 years, 33.13 cfs.

Extremes.--Maximum discharge during year, 128 cfs Apr. 11 (gage height, 0.927 ft); minimum, 

2.04 cfs Dec. 31 (gage height, 0.129 ft, backwater from aquatic vegetation); minimum 

dally, 6.4 cfs July 4.

1942-57: 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 dally, 

3.67 cfs Aug. 2, 1944.

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

backwater from aquatic vegetation, which are good, and those for periods of backwater 

from debris, which are fair. Plow 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 levels are collected, some of which 

are published In water-supply papers. See page 569 for results of discharge measurements of Long Island streams at sites other than regular gaging stations.

Note.--Backwater from aquatic vegetation Oct. l, 2, Oct. 6 to Nov. 8, Nov. 14 to Dec. 1, Feb. 18 

to Mar. 16, Mar. 19 to Apr. 9, Apr. 11 to June 5, June 7 to July 23, July 26 to Aug. 9, Aug. 11 to 

Sept. 28. Discharge per square mile and runoff in inches not computed because much of surface flow 

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

drainage.
26 STREAMS ON LONG ISLAND 

Swan River at East Patchogue, N. Y.

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

It miles upstream from mouth, and l£ miles east of Patchogue.

Drainage are a. About 8.8 sq mi.

Records available.--October 1946 to September 1957.

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

level, datum of 1929.

Average discharge. 11 years, 12.74 cfs.

Extremes. Maximum discharge during year, 39 cfs May 20, from rating curve extended above 

17 cfs by logarithmic plotting; maximum gage height, 1.117 ft Aug. 9 (backwater from 

debris below control); minimum discharge, 0.16 cfs Dec. 19 (gage height, 0.058 ft); 

minimum daily, 7.13 cfs Sept. 16.

1946-57: Maximum discharge, 47 cfs Aug. 12, 1955 (gage height, 1.521 ft, backwater 

from debris below control), from rating curve extended above 18 cfs by logarithmic 

plotting; maximum gage height, 1.801 ft Sept. 11, 1954 (backwater from debris below 

control); minimum discharge, 0.1 cfs Feb. 6, 1947 (gage height, 0.050 ft); minimum 

daily, 6.1 cfs Oct. 18, 1953.

Remarks. Records excellent except those for periods of backwater from 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 ground-water levels are collected, some of which are published in water-supply papers. See page 569 for results 

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

stations.

28 STREAMS ON LONG ISLAND

Connetquot River near Oakdale, N. Y.

Location. Lat 40°44'50", long 73°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 1957.

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. 14 years, 39.75 cfs.

Extremes. Maximum daily discharge during year, 62.6 cfs Apr. 6; minimum daily, 22.3 cfs 

Sept. 6.

1943-57: Maximum daily discharge, 263 cfs Oct. 16, 1955; minimum daily, that of 

Sept. 6, 1957.

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

"air.

_ _ _ _ _ record or backwater from aquatic vegetation, leaves", or high tide, which are fair. Flow 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 streamflow, records of ground-water levels are collected, some of which are published in water-supply papers. See page 569 for results 

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

stations.

Extremes. Maximum discharge during year, 27.5 cfs Apr. 2 (gage height, 0.716 ft, backwater from debris): minimum, 1.32 cfs Aug. 19 (gage height, 0.191 ft, backwater from 

aquatic vegetation).

1948-57: Maximum discharge, 129 cfs Oct. 15, 1955 (gage height, 1.411 ft), from 

rating curve extended above 32 cfs by logarithmic plotting; minimum, that of Aug. 19, 

1957.

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 569 for results of discharge measurements of Long Island streams at sites

Location. Lat 40°43 I 40", long 73°14'40", on right bank just upstream from Union Avenue in 

Bay Shore, Suffolk County, 4,500 ft upstream from mouth.

Drainage area. About 5 sq mi.

Records available. August 1945 to September 1957.

Gage. Water-stage recorder and concrete control. Datum of gage is 6.64 ft above mean sea 

level, datum of 1929.

Average discharge. 12 years, 6.10 cfs.

Extremes. Maximum discharge during year, 28 cfs Apr. 2 (gage height, 0.890 ft, backwater 

from aquatic vegetation); minimum, 2.56 cfs Aug. 2, 9, 18 (gage height, 0.298 ft). 

1945-57: Maximum discharge, 112 cfs Oct. 16, 1955 (gage height, 2.31 ft, from 

floodmarks), from rating curve extended above 34 cfs by logarithmic plotting; minimum, 

1.49 cfs Nov. 10, 1949 (gage height, 0.215 ft), result of temporary obstruction at 

culvert upstream.

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

or debris, which are good, and those for periods of no gage-height 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 569 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 and 

3,000 ft upstream from mouth.

Drainage area. About 23 sq mi.

Records available.--October 1944 to September 1957.

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

level, datum of 1929.

Average discharge. 13 years, 9.47 cfs.

Extremes. Maximum discharge during year, 33.1 cfs Apr. 5 (gage height, 0.867 ft); minimum, 3.0 cfs Aug. 2 (gage height, 0.252 ft, backwater from aquatic vegetation); minimum daily, 3.35 cfs Aug. 2.

1944-57: Maximum discharge, 110 cfs Oct. 16, 1955 (gage height, 1.672 ft, from 

reconstructed gage-height graph); 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.

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

or debris, which are good. 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 watersupply papers. See page 569 for results of discharge measurements of Long Island 

streams at sites other than regular gaging stations.

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 569 for results 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.--20 years (1937-57), 12.02 cfs.

Extremes. Maximum discharge during year, 66.7 cfs Oct. 7 (gage height, 1.17 ft, from 

reconstructed gage-height graph); minimum, 2.80 cfs Aug. 3 (gage height, 0.332 ft).

1903, 1936-57: Maximum discharge, 180 cfs Aug. 12, 1955 (gage height, 1.833 ft), 

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

0.322 ft).

Remarks.--Records good except those for periods of no gage-height 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 569 for results 

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

stations.

STREAMS ON LONG ISLAND 35

Wantagh Stream at Wantagh, N. Y.

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

boundary of village of Wantagh, Nassau County.

Drainage area.--About 17 sq mi.

Records available . June to October 1883 (fragmentary) and July to October 1903, published 

in Professional Paper 44, September 1937 to September 1957.

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.--20 years (1937-57), 10.09 cfs.

Extremes. Maximum daily discharge during year, 70.9 cfs Apr. 5; minimum daily, 3.65 cfs 

July 26, 27.

1903, 1937-57: Maximum daily discharge, 139 cfs Jan. 4, 1944; maximum discharge 

prior to beginning of diversion in November 1955, 340 cfs June 1, 1952 (adjusted to 

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

daily discharge, 1.84 cfs Sept. 12, 1943.

Remarks. Records fair. Prior to Nov. 4, 1955, 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. Subsequent to Nov. 3, 1955, permanent diversion of a substantial portion of the flow through west branch of Wantagh Stream. Discharge figures given are those of combined flows in main and diversion channels. 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 569 for results of discharge 

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

1942.

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

from debris, 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 569 for results of discharge measurements 

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

HUDSON RIVER BASIN 65

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

Location. Lat 43°27 I 20", long 75°19'25", on left bank at lock 69, 2 miles south of 

Boonvllle, Onelda County.

Records available. September 1915 to September 1942 (canal seasons only), October 1942 to 

September 1957.

Gage. Water-stage recorder and concrete control. Datura of gage Is 1,105.56 ft above mean 

sea level, datura 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 Lanslngklll spillway, 100 ft downstream from spillway headgates, 600 ft 

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

Extremes. 1915-57: Maximum daily discharge recorded, 323 cfs Nov. 30, 1915; practically 

no flow at times when no water Is being diverted.

Remarks. Records good except those for periods of backwater from debris at main gage or 

auxiliary gage, or shifting control at main gage, which are fair, and-those for periods 

of ice effect at main gage, which are poor. 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 Oct. 1 to May 30, Aug. 22 to Sept. 30, when no water was diverted, made up of 

leakage through headgates and runoff from area draining into canal above station.

Discharge, In cubic feet per second, water year October 1956 to September 1957

66 HUDSON KIVEK BASIN

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 hatchery, 

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

Drainage area. 150 sq mi.

Records available. October 1927 to September 1957 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 

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

datum.

Average discharge.--36 years (1921-57), 395 cfs (unadjusted).

Extremes. Maximum discharge during year, 1,040 cfs Apr. 23 (gage height, 4.08 ft); minimum, 99 cfs June 13 (gage height, 1.34 ft); minimum daily, 110 cfs June 12.

1927-57: 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 Jan. 17, 1931.

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

f

ood. During canal navigation season, water is diverted from Black River through 

orestport 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.

HUDSON RIVER BASIN 67

West Canada Creek at Hinckley, N. Y.

Location. Lat 43°18'20", long 75°07'10", on right bank at Hinckley, Oneida County, 1 mile 

downstream from Hinckley Dam, 1^ miles east of Prospect, and 6j miles upstream from 

Steuben Creek.

Drainage area. 375 sq mi.

Records available. June 1919 to September 1957.

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

Gas & Electric Co. datum).

Average discharge. 38 years, 992 cfs (unadjusted).

Extremes. Maximum discharge during year, 2,590 cfs May 21 (gage height, 5.73 ft); minimum, 350 cfs Sept. 30 (gage height, 3.71 ft); minimum daily, 350 cfs Sept. 30.

1919-57: Maximum discharge, 17,100 cfs Oct. 2, 1945, computed on basis of peak flow 

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

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

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

Remarks. Records excellent. 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.

1 mile downstream from North Creek, and 4 miles upstream from mouth and Herklmer.

Drainage area. 556 sq ml.

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 1957 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. 37 years (1920-57), 1,331 cfs.

Extremes. Maximum discharge during year, 11,400 cfs Jan. 23 (gage height, 6.36 ft); minimum, 143 cfs Aug. 29 (gage height, 1.48 ft); minimum dally, 344 cfs Sept. 1, 13.

1920-57: 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 dally, 59 cfs 

Sept. 2, 1929.

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

and surveyor.

Remarks. Records excellent except those for periods of Ice effect or no gage-height record, which are good. Since 1916, flow slightly regulated by Hlnckley 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 Nlnemlle feeder during canal 

navigation season.

70 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 Rocky Rift 

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

Palls, Herkimer County.

Drainage area. 1.348 sq mi.

Records available. February to April 1901 and October 1927 to September 1957 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 1,800 ft upstream at different datum.

Average discharge. 30 years (1927-57), 2,777 cfs.

Extremes. Maximum discharge during year (river channel only), 10,600 cfs Feb. 27 (gage 

height, 11.29 ft); maximum gage height 15.34 ft Jan. 23 (ice jam); minimum discharge 

(river channel only), 500 cfs Sept. 1 (gage height, 4.50 ft); minimum daily (including 

canal), 686 cfs Sept. 10.

1927-57: 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 gageheight record, which are fair. Records of daily discharge include diversion at Rocky 

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

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

Canal (flowing south) and Lansing Kill, and 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). 

Records of chemical analyses and water temperatures for the water year 1957 are given in 

WSP 1520.

HUDSON RIVER BASIN 75

Mohawk River at Cohoes, N. Y.

Location. Lat 42 e47'05", long 73e42'25", 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 1957.

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. 32 years, 5,690 cfs.

Extremes. Maximum discharge during year, 23.000 cfs Jan. 24 (gage height, 14.90 ft); minimum, 49 cfs Oct. 14 (gage height, 3.52 ft); minimum daily, 101 cfs Sept. 29.

1925-57: Maximum discharge, 130,000 cfs Mar. 19, 1936 (gage height, 22.57 ft), from 

rating curve extended above 34,500 cfs by logarithmic plotting; minimum, 6 cfs Sept. 28, 

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

Remarks. Records excellent except those for periods of ice effect, which are 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 and suspended sediment loads for 

the water year 1957 are given in WSP 1520.

HUDSON RIVER BASIN 77

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.

Records available.--February 1946 to September 1957.

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

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

bypass channel at datum 10.59 ft higher.

Average discharge. 11 years, 13,930 cfs.

Extremes. Maximum discharge during year, 43,400 cfs Jan. 24; maximum gage height, 19.62ft 

Jan. 24; minimum daily discharge, 1,380 cfs Sept. 2; minimum gage height, 14.37 ft 

Sept. 3.

1946-57: 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. 

Records do not include flow in bypass channel (a diversion from Mohawk River entering 

Hudson River 1| miles downstream). Average flow in bypass channel during current year 

was 16 cfs. Appreciable regulation by Sacandaga Reservoir (see p. 48) , Indian Lake 

(see p. 41), and Delta, Hinckley, and Sehoharie 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 (seep, 51,52), and Champlain Canal and 

occasionally may be recieved from that basin through summit level of Champlain Canal at 

Dunham Basin. Records of water temperatures for the water year 1957 are given in 

WSP 1520.

Cooperation. PoMerPlant records furnished by Ford Motor Co. in connection with a Federal 

Power Commission project.

Discharge, in cubic feet per second, water year October 1956 to September 1957

HUDSON RIVER BASIN 85

Rondout Creek at Rosendale, N. Y.

Location.--Lat 41°50'35", long 74°05'10", on left bank 30 ft upstream from upper highway 

bridge (relocated) 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 1957, in reports of Geological Survey. January 1914 to January 1919 

in reports of State engineer and surveyor.

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

1929. Prior to January 1919, chain gage on highway bridge 150 ft downstream at datum

4 .0 ft lower.

Extremes --Maximum discharge during year. 4,530 cfs Apr. 6 (gage height, 7.06 ft); maximum 

gage height, 7.11 ft Jan. 23 (ice jam); minimum discharge, 8.6 cfs Sept. 26, 29; minimum gae;e height observed, 1.15 ft Oct. 30; minimum daily discharge, 25 cfs July 25.

19U1-3, 1906-19, 1926-57: Maximum discharge, 35,800 cfs Oct. 16, 1955 (gage height, 

CD.8 ft, from floodmarks), from rating curve extended above 15,000 cfs on basis of 

contracted-opening determination at gage height 23.93 ft; minimum, 4.1 cfs Aug. 19, 

1954; minimum gage height observed, that of Oct. 30, 1956; minimum daily discharge, 

8.5 cfs Sept. 3U, 1948.

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

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

Some regulation by Rondout Reservoir since October 1950. Subsequent to May 1951, 

entire flow above Merriman Dam (drainage area, 94.4 sq mi), except for conservation 

releases and during periods of spilling, diverted from Rondout Reservoir for water 

supply of city of New York. Diversion from Rondout Creek through the emergency connection to the Delaware Aqueduct at Lackawack for water supply of city of New York 

began in April 1944.

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

Shawangunk Kill at Pine Bush, N. Y.

Location.--Lat 41°37'05", long 74°17'40", on left bank 50 ft downstream from Hardenburg 

Bridge, half a mile northeast of Pine Bush, Orange County, 2-J- miles downstream from 

Pakanasink Creek and 11 miles above mouth at Ganahgote.

Drainage area. 102 sq mi (revised).

Records available.--September 1924 to September 1932, June to September 1957.

Gage.--Water-stage recorder. Altitude of gage is 305 ft (from topographic map). Prior to 

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

Average discharge. 8 years (1924-32), 154 cfs.

Extremes.--Maximum discharge during period, 90 cfs Sept. 4 (gage height. 1.28 ft); minimum, 

2.3 cfs July 21, 22; minimum gage height, 0.47 ft Aug. 19, 20.

1924-32, 1957: Maximum discharge, 7,350 cfs (revised) 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 determination 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, that of July 21, 22, 1957.

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 cfs, 

based on unit runoff at Winterton and at Ganahgote).

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

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

papers indicated.

Location. Lat 40 0 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 1957.

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.--36 years, 23.0 cfs (unadjusted).

Extremes.--Maximum discharge during year, 1,500 cfs Aug. 26 (gage height, 8.49 ft); minimum daily, 5.5 cfs Oct. 14.

1921-57: 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. Diversion by pumpage from Hammock well field, in Union, for municipal supply by Elizabethtown Water Co. probably reduces the flow past the station. 

Plow occasionally regulated at Ursino Lake Dam.

stilling box at left end of dam at same datum.

Average discharge. 35 years, 47.6 cfs.

Extremes. Maximum discharge during year, 518 cfs Apr. 6 (gage height, 3.19 ft); minimum, 

0.2 cfs Oct. 1-22, leakage through dam when Ravine Lake was filling.

1922-57: Maximum discharge, 3,410 cfs Mar. 15, 1940 (gage height, 5.85 ft), from 

rating curve extended above 500 cfs by weir formula; no flow at times when Ravine Lake 

was filling.

Stage of 7.6 ft, from floodmark, occurred July 23, 1919 (discharge, about 7,000 cfs).

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

when Ravine Lake was filling, which,are fair. Figures of discharge include 2 cfs diverted by small turbine at dam Apr. 11 to Sept. 30.

Rarltan River at Manvllle, N. J.

Location. Lat 40°33'18", long 74°35'02", on left bank at downstream side of highway 

bridge at Manvllle, Somerset County, l£ miles upstream from Millstone River.

Drainage area.--490 sq ml.

Records available.--June 1903 to March 1907 (published as "at Flnderne"), August 1908 to 

April 1915 (gage heights only, published In WSP 521), August 1921 to September 1957.

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

1929. 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. 36 years (1921-57), 758 cfs (adjusted for diversion since Oct. 1, 

1940) .

Extremes. Maximum discharge during year, 10.800 cfs Apr. 5; maximum gage height, 13.1 ft 

Apr. 5, 6; minimum dally discharge, 22 cfs Aug. 20.

1903-7, 1921-57: Maximum discharge. 36,100 cfs Sept. 22, 1938 (gage height, 20.42 

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; maximum gage 

height, 22.1 ft Aug. 19, 1955; minimum discharge, about 15 cfs Sept. 12, 1932 (does not 

Include water diverted to Johns-Manvllle plant).

Remarks. Records good except those for periods of Ice effect or those when fall was used 

as a factor, which are fair. Diversion to Johns-Manvllle plant, 1,500 ft above station, returned to river 0.6 mile below station. Slight diurnal fluctuation at low 

flow.

Revisions (water years). WSP 801: 1904 (M), 1933(M).

RARITAN RIVER BASIN 

Green Brook at Plainfield, N. J.

143

Location. Lat 40°36'50", long 74"25'55", 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 1957.

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

sea level, datum of 1929.

Average discharge. 19 years, 12.0 cfs (unadjusted).

Extremes. Maximum discharge during year, 285 cfs Apr. 5 (gage height, 2.41 f|t); minimum 

daily, 0.3 cfs June 21.

1938-57: 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 (a peak overflow of about 4,000 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. Water diverted from Baltusrol well field by Commonwealth Water 

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

Water Co. for municipal supply and from private and industrial wells in Plainfield 

and vicinity. Diurnal fluctuation at low flow caused by pumping from wells near river 

in Plainfield. During extreme high stages there is considerable overflow from Green 

Brook basin to adjacent Cedar Brook basin, which returns to Green Brook 5.1 miles 

below gage by way of Bound Brook.

DELAWARE RIVER BASIN 169

East Branch Delaware River at Pishs Eddy, N. Y.

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

bridge at Pishs Eddy, Delaware County, Just upstream from Pish 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 1957.

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, 8,270 cfs Apr. 6 (gage height, 9.67 ft); maximum 

gage height observed, 10.95 ft Jan. 23 (ice jam); minimum daily discharge, 190 cfs 

Sept. 10; minimum gage height, 1.90 ft Sept. 10.

1912-57: 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, no gage-height record, 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. 244). 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 basin, as directed by the Delaware River Master.

Revision. WSP 756: Drainage area.

188 DELAWARE RIVER BASIN

Wallenpaupack Creek at Wilsonville, Pa.

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

 stock, at Kimble, 3 miles east of dam at lat 41°27 I 35", long 75°11'10", at Wilsonville, 

Wayne County, l£ miles south of Hawley.

Drainage area. 228 sq mi.

Records available . October 1918 to September 1921 and June 1926 to September 1957 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.--41 years (1913-22, 1925-57), 370 cfs (adjusted for storage).

Extremes.--1913-22 . 1925-57: 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 output, 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 during year. Flow regulated by Lake Wallenpaupack (see p. 244).

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

water-surface elevations in lake furnished by Pennsylvania Power and Light Co., in connection with a Federal Power Commission project.

Revisions (water years).--WSP 756: Drainage area. WSP 1432: 1920-21.

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 Jervis, Orange County, 1-j miles upstream from Neversink River, and 6.5 miles downstream from Mongaup River.

Drainage area. 3,076 sq mi.

Records available. October 1904 to September 1957.

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, staff or 

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

Extremes.--Maximum discharge during year, 42,400 cfs Apr. 7 (gage height, 9.76 ft); mini- 

 mum, 504 cfs Sept. 27 (gage height, 1.43 ft); minimum daily, 828 cfs Sept. 29.

1904-57: 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 basis of slopearea determination of peak flow; 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 period of ice effect, which are good. Flow 

regulated by Lake Wallenpaupack, and by Toronto, Cliff Lake, and Swinging Bridge Reservoirs (see p. 244) and small 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. 244). 

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.

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

25, Nov. 30 to Dec. 2, Dec. 30 to Feb. 6,
DELAWARE RIVER BASIN 195

Neversink River at Godeffroy, N. Y.

Location. Lat 41°26'30", 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.--3Q2 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 1957 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 45y.66 ft above mean sea level (levels by

"(Torps of Engineers). August to October 1903 staff gage at datum 0.98 ft higher (revised). Aug. 22, 1909, to Jan. 21, 1910, staff gage and Aug. 1, 1910, to Apr. 30, 

1914, chain gage, at present datum (revised).

Extremes.--Maximum discharge during year, 2,680 cfs Jan. 23 (gage height, 5.99 ft), result 

of release from upstream ice jam; minimum, 48 cfs June 11 (gage height, 2.69 ft), result of regulation, cause unknown.

1903, 19U9-14, 1937-57: Maximum discharge, 33,000 cfs Aug. 19, 1955 (gage height, 

12.49 ft), from rating curve extended above 11,000 cfs on basis of slope-area measurement 

of peak flow; practically no flow several times in July 1911 (revised).

Revisions.--The maximum discharge for the water year 1951 has been revised to 24,500 

cfs Nov. 26, 1950 (gage height, 11.79 ft), superseding figure published in WSP 1202.

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

aquatic vegetation, which are good. Subsequent to June 1953, entire flow from 

91.8 sq mi of drainage area controlled by Neversink Reservoir (see p. 245). Part of 

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

conservation releases and spillage) impounded for release during periods of low flow in 

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

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

Revisions.--WSP 821: Drainage area.

Rating tables, water year 1956-57, except periods of ice effect or backwater from aquatic 

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

286 SUSQUEHANNA RIVER BASIN

Albrlght Creek at East Homer, N. Y.

Location. Lat 42°40'10", long 76"06"15", on left bank a quarter of a mile upstream from 

highway bridge In East Homer, Cortland County, and half a mile upstream from mouth.

Drainage area. 7.08 sq ml.

Records available. October 1938 to September 1957. Prior to October 1947, published as 

East Homer Creek at East Homer.

Gage. Water-stage recorder and concrete control. 

Average discharge. 18 years (1939-57), 12.3 cfs.

Extremes. Maximum discharge during year, 548 cfs June 13 (gage height, 3.42 ft, from 

floodmark in well); minimum, 0.32 cfs Sept. 10, 11 (gage height, 0.70 ft).

1938-57: Maximum discharge, 787 cfs June 3, 1947, from rating curve extended above 

220 cfs by logarithmic plotting; maximum gage height, 3.80 ft Dec. 30, 1942, from graph 

based on outside gage reading; no flow for part of Aug. 24, 1953, result of probable 

temporary interference upstream; minimum daily discharge, 0.030 cfs Aug. 6, 1955.

Remarks. Records good except those for periods of Ice effect, shifting control, or doubtful 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.

Gage. Water-stage recorder. Datum of gage Is 1,016.58 ft above mean sea level, adjustment of 1912. Prior to Mar. 5, 1937, chain gage on highway bridge at same site and 

datum.

Average discharge. 39 years, 448 cfs.

Extremes. Maximum discharge during year, 4,710 cfs Apr. 6 (gage height, 5.45 ft); maximum 

gage height, 8.14 ft Jan. 23 (Ice jam); minimum discharge, 38 cfs Sept. 11 (gage height, 

0.64 ft, backwater from aquatic vegetation).

1918-57: Maximum discharge, 41,100 cfs July 8, 1935 (gage height, 11.6 ft, from 

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

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

Sept. 6,7, 1954.

Remarks. Records excellent except those for periods of Ice effect or backwater from aquatic vegetation, which are fair. During each year a large part of flow from 45 sq ml of 

drainage area above Lake Lamoka Outlet on Mud Creek, a tributary above this station, Is 

diverted Into Keuka Lake (St. Lawrence River basin) for power development.

Drainage area.--216 sq mi.

Records available.--October 1918 to December 1919, and June 1954 to September 1957 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. 11 years (1910-16, 1917-19, 1954-57), 297 cfs.

Extremes. Maximum discharge during year, 1,320 cfs Dec. 14, Apr. 5; maximum gage height, 

4.72 ft Dec. 14; minimum discharge, 35 cfs Sept. 5 (gage height, 0.38 ft).

1909-19, 1954-57: 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. 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.

Conestoga Creek at Lancaster, Pa.

Location.--Lat 40°03'00", long 76°16'40", on left bank at Pennsylvania Railroad bridge, 

50 ft downstream from small tributary, 500 ft downstream from diversion dam of city 

waterworks, and 0.75 mile east of Lancaster, Lancaster County.

Drainage area.--324 sq mi.

Records available . September 1928 to September 1957.

Gage.--Water-stage recorder and concrete control. Datum of gage is 245.63 ft above mean 

sea level, datum of 1929, supplementary adjustment of 1943. Prior to May 1, 1933, at 

site 600 ft upstream at different datum, excluding small tributary.

Average discharge.--27 years (1928-31, 1933-57), 388 cfs (adjusted for diversion).

Extremes. Maximum discharge during year, 4,040 cfs Apr. 5 (gage height, 7.59 ft); minimum, 19 cfs Aug. 22, 26 (gage height, 2.42 ft).

1928-57: Maximum discharge, 22,800 cfs Aug. 24, 1933 (gage height, 17.52 ft, from 

floodmark in recorder shelter), from rating curve extended above 4,000 cfs on basis of 

slope-area determination of peak flow; probably no flow at times; minimum daily, 7 cfs 

Aug. 11, 1930.

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

Regulation at low flow by waterworks and mill above station. Diversion above station 

for municipal supply of Lancaster.

Revisions. WSP 1202: Drainage area.

Correction. Discharge for supplemental peak of Oct. 27, 1942, not previously published, 

was 3,910 cfs, and that for supplemental peak of Feb. 11, 1943, published in error in 

WSP 971, is corrected to 3,650 cfs.

Big Spring at Masonvllle, W. Va.

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

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

Records available.--August 1945 to September 1957.

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

""opographic 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. 12 years, 13.3 cfs. 

Extremes. Maximum discharge during year, 52 cfs Apr. 9 (gage height, 1.77 ft); minimum 

daily, 6.3 cfs Dec. 12, 13.

1945-57: 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 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. Plow from surface is included in the records but is relatively 

small except during heavy rains.

or Big Tonoloway Creek).

Drainage area. 4,073 sq ml.

Records available. October 1932 to September 1957. Gage-height records collected at same 

site since June 1925 are contained In reports of U. S. Weather Bureau.

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. 25 years, 4,064 cfs.

Extremes. Maximum discharge during year, 47,200 cfs Feb. 11 (gage height, 19.43 ft); minimum, 221 cfs Sept. 8 (gage height, 2.17 ft).

1932-57: 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 period of once-daily tape-gage readings, which 

are good, and those for period of Ice effect, which are fair. Slight regulation at low 

flow from powerplants upstream. Low flow affected slightly by Stony River Reservoir 

(see p. 452) and since December 1950 by Savage River Reservoir (see p. 455).

Potomac River at Point of Rocks, Md.

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

U.S. Highway 15 at Point of Rocks, Frederick County, a third of a mile downstream from 

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

Drainage area. 9,651 sq mi.

Records available. February 1895 to September 1957.

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.--61 years (1896-1957), 9,351 cfs.

Extremes.--Maximum discharge during year, 69,200 cfs Apr. 7 (gage height, 13.74 ft); minimum, 787 cfs Sept. 9 (gage height, 0.53 ft).

1895-1957: 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 good except those for period of ice effect, which are fair. Low flow 

affected slightly since 1913 by Stony River Reservoir (see p. 452) and since December 

1950 by Savage River Reservoir (see p. 455).

Revisions (water years). WSF 192: 1895-1905. WSP 1432: 1899, 1901-2, 1904-5, 1912, 

1914(M), 1915, 1918, 1919(M) , 1920, 1921-23(M), 1924, 1925-28(M) , 1930(M) .

Suburban Sanitary Commission bench mark). Prior to June 12, 1942, wire-weight gage at 

same site and datum.

Average discharge. 19 years, 78.2 cfs.

Extremes. Maximum discharge during year, 1,020 cfs Apr. 5 (gage height, 4.30 ft); minimum, 5.8 cfs Aug. 16, 23, 24, 25.

1938-57: Maximum discharge, 3,680 cfs July 18, 1945; maximum gage height, 12.93 ft 

Oct. 16, 1942; minimum discharge observed, 5.6 cfs Sept. 29, 30, Oct. 1, 1941.

Maximum stage known, about 15.5 ft Aug. 23 or 24, 1933, from floodmarks (discharge, 

10,500 cfs, from rating curve extended above 3,000 cfs on basis of velocity-area study).

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

or those based on twice-daily wire-weight-gage readings, which are fair.

Rating tables, water year 1956-57, except periods of loe effect (gage 

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

POTOMAC RIVER BASIN 525

Accotlnk Creek near Accotlnk Station, Va.

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

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

Calamo Branch.

Drainage area. 37.0 sq ml.

Records available. May 1949 to June 1957 (discontinued).

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

Average discharge. 7 years (1949-56) , 38.8 cfs.

Extremes. Maximum discharge during the period October 1956 to June 1957, 1,380 cfs Apr. 6

 (gage height, 10.22 ft); minimum, 4.6 cfs June 20.

1949-57: Maximum discharge, 3,120 cfs Aug. 13, 1955 (gage height, 14.21 ft); minimum dally, 0.6 cfs many days In November, December 1954; minimum gage height, 2.96 ft 

Sept. 10, 1949.

Remarks . Records fair except those for periods of indefinite stage-discharge relation,

 which are poor. Field maneuvers by U. S. Army cause some regulation. Occasional regulation by Fort Belvoir Reservoir 4.2 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.

Remarks. Records do not include diversion by pumps of part of low flow into Anacostia 

River basin since Aug. 12, 1939 (see records for Northwest Branch Anacostia River near 

Colesville). Flow regulated by Triadelphia Reservoir since June 27, 1942 (usable capacity, 3,380,000,000 gal, corrected).

Revisions. Revised figures of discharge, in cubic feet per second, for the water years 

1912, 1915, 1918-1920, 1925-26, 1928, superseding those published in WSP 321, 401, 471,

DISCHARGE MEASUREMENTS AT POINTS OTHER THAN GAGING STATIONS 569

Measurements of streamflow made at points other than regular gaging stations in the 

area covered by this report 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 587.

Discharge measurements made at points other than gaging stations during water year 1957

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 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. 

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.
