SURFACE WATER SUPPLY OF NORTH ATLANTIC SLOPE BASINS, 1949

SCOPE OF WORK

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

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

water year ending September 30, 1949. The work was begun in 1888 in connection with 

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

stage and contents of lakes and reservoirs have been made at about 11,680 gaging stations 

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

30, 1949, 6,240 gaging stations, including those in Hawaii and Alaska were being maintained by the Geological Survey and cooperating organizations. Miscellaneous discharge 

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

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

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

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

volume, the section on cooperation of the second kind appears on page 12.

DEFINITION OF TERMS

The units in which stream-flow data are presented in this report and other terms used 

herein are defined as follows:

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

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

whose average velocity is. 1 foot per second.

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

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

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

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

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

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

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

with storage for irrigation.

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

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

represents a runoff of 0.0372 inch from 1 square mile.

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

and discharge."

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

a reach of the channel, or an artificial structure.

2 SURFACE WATER SUPPLY, 1949, PART 1

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

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

EXPLANATION OF DATA

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

by a footnote.

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

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

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

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

greater part of the year was determined by the shifting-control method, the slope method, 

or other special methods.

The description of the station gives the type of gage, location, drainage area, records 

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

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

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

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

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

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

crest stage, obtained by use of a water-stage recorder or a nonrecording gage read at the 

time of the crest. Information pertaining to the accuracy of the records and conditions 

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

published in the annual series of reports.

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

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

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

indicate the true daily mean discharge, 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
ACCURACY OF FIELD DATA AND COMPUTED RESULTS 5

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

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

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

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

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

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

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

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

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

feet per second during the month.

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

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

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

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

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

by man.

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

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

but is omitted from succeeding reports.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

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

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

records.

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

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

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

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

square mile" and "runoff in inches" are not published unless storage or diversion records 

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

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

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

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

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

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

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

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

the average annual rainfall over the drainage area is less than 20 inches.
6 SURFACE WATER SUPPLY, 1949, PART 1

Many gaging stations on stre'ams in the irrigated are.as of the United States are situated 

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

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

the station must first be satisfied.

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

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

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

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

subject to revision in succeeding water-supply papers.

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

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

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

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

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

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

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

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

sunmary of yearly discharge at gaging stations at which 10 or more complete years of record 

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

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

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

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

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

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

KENWEBEC RIVER BASIN

Kennebec River at Bingham, Maine

Location.--Water-stage recorder, lat. 45°03'05", long. 69°53'15", at Bingham, Somerset 

"County, 200 feet downstream from highway bridge, half a mile downstream from Austin 

Stream, if miles downstream from Wyman Dam. Datum of gage is 330.2 feet above mean 

sea level, adjustment of 1929.

Drainage area.--2,710 square miles.

Records available.--June 1907 to June 1910, October 1930 to September 1949.

Average discharge.--21 years (1907-9, 1930-49), 4,146 second-feet.

Extremes.--Maximum discharge during year, 14,200 second-feet May 4 (gage height, 9,38 

feet); minimum daily, 830 second-feet Mar. 27,

1907-10, 1930-49: Maximum discharge, 55,200 second-feet Mar. 20, 1936 (gage height, 

14.44 feet), from rating curve extended above 16,000 second-feet on basis of computations of flow at Wyman Dam plus inflow; minimum daily, 110 second-feet Dec. 25, 1947.

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

record, which are good. Flow regulated by Moosehead (see p. 41 ), Brassua, Moxie and 

Spencer Lakes, First Roach, Second Roach, Dead River and Wyman Ponds (see following page). 

Considerable diurnal fluctuation caused by power plants above station.

MERRIMACK RIVER BASIN 77

Merrimack River at Franklin Junction, N. H.

Location. --Water-stage recorder, lat. 43°25'25", long. 71°39'10", at Franklin Junction, 

Merrimack County, 1 mile downstream from confluence of Pemigewasset and Winnipesaukee 

River. Datum of gage is 250.4 feet above mean sea level, unadjusted.

Drainage area.--1.507 square miles.

Kecords available.--.July 1903 to September 1949.

Average discharge.--44 years (1905-49), 2,750 second-feet.

Extremes.--Maximum discharge during year, 17,500 second-feet Jan. 1 (gage height, 13.99 

reet); minimum daily, 225 second-feet Oct. 23.

1903-49: Maximum discharge, 83,000 second-feet Mar. 19, 1936 (gage height, 36.4 

feet, from floodmarks), from rating curve extended above 30,000 second-feet on basis of 

velocity-area studies, slope-area determination, and computation of flow over dam; 

minimum daily, that of Oct. 23, 1948.

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

which are fair. Flow regulated by power plants and by Franklin Falls Reservoir, Squam, 

Little Squam, Newfound, Winnipesaukee, Winnisquam, Wentworth, Merrymeeting, and other 

Lakes. See pages 81, 86 for description and monthly change in contents of many of 

these reservoirs.

mean sea level, datum of 1929.

Drainage area. --Total above gage, 4,635 square miles; 'net above gage, 4,425 square miles 

(flow1 diverted from 210 square miles for use of Boston metropolitan district and city of 

Worcester). Prior to July 1, 1937, | net above gage, 4,424 square miles (flow diverted 

from 211 square miles for use of Boston metropolitan district and city of Worcester).

Records available. --June 1923 to September 1949.

Average discharge. --26 years, 6,976 second-fteet (adjusted for wastage into Merrimack River).

Extremes . --Maximum discharge during year, 24,600 second-feet Jan. 8 (gage height, 47.65 

Feet); minimum daily, 262 second-feet July 31.

1923-49: Maximum discharge, 173,000 second-feet Mar. 20, 1936 (gage height, 68.4 

feet, from f loodmarks ) ; minimum daily, 199 second-feet Sept. 23, 1923.

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

and those below 1,000 second-feet, which are good. Figures of daily discharge include 

water wasted in diverting drainage from basins of Sudbury and South Branch Nashua Rivers 

and Lake Cochituate for use of Boston metropolitan district. Flow regulated by power 

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

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

Location.--Water-stage recorder, lat. 41°54'30", long. 71°54'30", at Putnam, Windham

county, 600 feet downstream from Muddy Brook (Little River) and 3 miles downstream from 

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

Drainage area. 331 square miles.

Kecords available.--December 1929 to September 1949.

Average discharge.--20 years, 541 second-feet.

Extremes.--Maximum discharge during year, 1,820 .second-feet Jan. 6 (gage height, 5.95 

reet); minimum, 18 second-feet Aug. 7 (gage height, 1.60 feet); minimum daily, 26 

second-feet Aug. 7.

1929-49: Maximum discharge, 20,900 second-feet Sept. 21, 1938 (gage height, 19.45 

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

Muddy Brook (Little River) 2 miles upstream from its mouth; minimum, 8.5 second-feet 

Oct. 26, 1935; minimum daily, 11 second-feet Oct. 5, 12, 1930.

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

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

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

caused by many dams and reservoirs above station., largest of which is Lake Chaubunagungamaug 

with an estimated usuable capacity of 207,000,000 cubic feet.

* Winter discharge measurement made on this day. 

a No gage-height record; discharge computed on basis of weather records and records for East Branch 

Eightmile River near North Lyme.

b Stage-discharge relation affected by ice.
MENUNKETESUCK RIVER BASIN 

Menunketesuck River near Clinton, Conn.

231

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

downstream from Cobbs Bridge, 1.7 miles north of Clinton, Middlesex County, 2.4 miles 

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

Drainage area. 11.6 square miles.

Kecoras available. June 1941 to September 1949.

extremes (unaqjus'ted for storage or diversion) . Maximum discharge during year, 510 secondfeet Dec. di (gage neigrvc, 5.is reet, oacicwater from debris), from rating curve extended 

above 270 second-feet on basis of logarithmic plotting; minimum, 0.03 second-foot Aug. 

22-24 (gage height, 0.68 foot).

1941-49: Maximum discharge, 870 second-feet Nov. 12, 1947 (gage height, 6.72 feet), 

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

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

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

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

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

daily diversion from Kelseytown Reservoir as measured by venturi meter. During periou_ 

of low flow, diversions from Kelseytown Reservoir are compensated for by release of 

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

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

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

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

discharge record for periods of low flow Oct. 1 to Nov. 11, June 12-15, June 18 to 

Sept. 1, Sept. 4-30 is a summation of daily flow at gaging station and dally diversion 

from Kelseytown Reservoir, minus daily draft on Killingworth Reservoir adjusted for 

daily change in contents in Kelseytown Reservoir. Draft on Killingworth Reservoir is 

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

taken of evaporation from the reservoir surfaces. Plow at recording gage station regulated by Killingworth and Kelseytown Reservoirs and by diversion for domestic water 

supply from Kelseytown Reservoir.

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

water uo.

HOUSATONIC RIVER BASIN 237

Housatonic River at Stevenson, Conn.

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

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

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

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

Drainage area. 1,545 square miles.

KecOrda available. August 1928 to September 1949.

Average discharge'. 21 years, 2,502 second-feet (adjusted since 1936).

Extremes.--rcajTStruin discharge during year, 51,800 second-feet Dec. 31 (gage height, 19.97

 ieet); minimum,.44 second-feet Sept. 20 (gage height, 0.50 foot); minimum daily, 50 

second-feet Sept. 11.

 1928-49: Maximum discharge, 69,500 second-feet Mar. 12, 1936 (gage height, 23.5 

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

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

Remarks. Records excellent. Ordinary flow completely regulated by Stevenson hydroelectric plant. Plow regulated by Candlewood Lake, Lake Zoar and Shepaug Reservoir having a combined usable capacity of 6,600,000,000 cubic feet (see following page), 

and by small diversion from basin at Shepaug Reservoir.

HOUSATONIC RIVER BASIN 241

Shepaug River- at Woodvllle, Conn.

Location.--Nonrecording gages at dam at outlet of Shepaug Reservoir, lat. 41°43'16", long.

 73°17'40", 1 mile north of Woodvllle, Litchfield County, and 3 miles upstream from 

Bantam River.

Drainage area. 38.0 square miles.

Records available. October 1935 to September 1949.

Average discharge. 14 years, 81.6 second-feet (adjusted).

Extremes . Maximum discharge observed during year, 5,160 second-feet Dec. 31; no flow

 Nov. 2 to Dec . 29.

1935-49: Maxijnum discharge observed, 6,000 second-feet Sept, 21, 1938; no flow at 

times.

Remarks. Records good'except those for periods of rapidly changing stage, which are 

rair. Discharge computed on basis of flow over spillway, through floodgates, and 

through fountain at toe of dam. Rating curves for floodgates and fountain computed 

by means qf a temporary sharp-crested weir below dam. Rating curve for spillway computed for discharges below 18.5 second-feet by means of same weir and for discharges 

above 18.5 second-feet by a formula selected to fit spillway-crest sections. Gages 

at dam usually read once daily. Water diverted from Shepaug Reservoir for municipal 

supply of Waterbury. Plow regulated since September 1933 by Shepaug Reservoir (see 

p. 238).

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

Revisions (water years). W 971: 1936-42.

mean sea level, datum of 1929.

Drainage area.--9.20 square miles.

Kecoras available. November 1943 to September 1949.

.Extremes. --Maximum discharge during year, 534 second,-feet Jan. 6 (gage height, 4.67 feet); 

minimum, 0.40 second-foot Aug. 11 (gage height, 0.89 foot).

1943-49: Maximum discharge, 1,330 second-feet Sept. 15, 1944 (gage height, 9.36 

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

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

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

Medium flow affected slightly by detention reservoir 2 miles above station (capacity, 

about 26 acre-feet at spillway level or 50 acre-feet at crest of concrete dam).

254 STREAMS ON LONG ISLAND

Mill Neck Creek at Mill Neck, N. Y.

Location.--Water-stage recorder and steel sheet-piling control, lat. 40~53'15", long. 

7a"a3'55", at Beaver Dam and highway bridge on Peeks Lane (Cleft Road) in Mill Neck, 

Nassau County. Datum of gage is 6.55 feet above mean sea level, adjustment of 1912.

Drainage area. About 11.5 square miles (revised).

Keeords available.--January 1937 to September 1949.

Average discharge.--12 years, 9.64 second-feet.

Extremes.--Maximum discharge during year, 40.8 second-feet Dec. 31 (gage height. 0.820 

root); minimum, 6.46 second-feet July 4 (gage height, 0.256 foot).

1937-49: Maximum discharge, 104 second-feet Sept. 15, 1944, from rating curve 

extended above 25 second-feet on basis of logarithmic plotting; maximum gage height, 

4.85 feet Sept. 21, 1938 (hurricane wave); minimum discharge, 0.09 second-foot Dec. 11, 

1941 (from discharge measurement); minimum gage height, 0.232 foot Dec. 11, 1943.

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

which are good. This station is operated in connection with an inventory of groundwater resources on Long Island. In addition to records of stream flow, records of 

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

vegetation); minimum daily, 32.5 second-feet July 31, Aug. 21.

1943-49: Maximum discharge, 147 second-feet Sept. 14, 1944 (gage height, 1.32 feet, 

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

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

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

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

which are good. Flow partly regulated by cleaning of fish screens and trash racks at 

outlets of Blydenburgh Pond on main stream and ponds on tributaries entering stream 

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

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

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

septemoer iyiy.

Average discharge. 12 years (1937-49), 11.66 second-feet.

Extremes.--maximum discharge during year, 49.3 second-feet May 3 (gage height, 1.025 feet); 

minimum, 6.50 second-feet Aug. 28 (gage height, 0.472 foot).

1903, 1936-49: Maximum discharge, 151 second-feet Jan. 7, 1944 (gage height, 1.616 

feet), from rating curve extended above 68 second-feet on "basis of logarithmic plotting; 

minimum, 3.05 second-feet Sept. 12, 1937 (gage height, 0.36 foot).

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

rrdm aquatic vegetation or debris, which are good. This station is operated in connection with an inventory of ground-water resources on Long Island. In addition to 

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

published in water-supply papers.

1.84 second-feet Sept. 12, 1943.

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. Plow regulated to some extent by Browning Pond, half a mile above station. Thisstation is operated in connection with an inventory of ground-water resources on Long 

Island. In addition to records of stream flow, records of ground-water levels are 

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

276 HUDSON RIVER BASIN

Hudson River at Green Island, N. Y.

Location.--Water-stage recorder, lat. 42°45'10", long. 73°41'20", at Green Island, Albany 

county, just upstream from Troy Lock and Dam and half a mile downstream from 5th branch 

Mohawk River. Datum of gage Is 0.31 foot below mean sea-level, datum of 1989 (Corps of 

Engineers bench mark). Auxiliary gage on bypass channel (6th branch Mohawk River) at 

Arch Street Bridge at datum 10.59 feet higher.

Drainage area.- 8,090 square miles (Including that above site of auxiliary gage). 

Records available. February 1946 to September 1949.

Extremes (main channel).--Maximum discharge during year, 181,000 second-feet Dec. 31 (gage 

neignt, 27.ub reet, from high-water mark in well); maximum daily discharge, 141,000 

second-feet Dec. 31, Jan. 1; minimum daily, 1,270 second-feet Sept. 5; minimum gage 

height, 14.03 feet Aug. 8.

1946-49: Maximum discharge, that of Dec. 31, 1948; maximum daily, that of Dec. 31, 

1948, Jan. 1, 1949; minimum daily, that of Sept. 5, 1949; minimum gage height, 13.92 

feet Sept. 2, 1946.

Flood of Mar. 19, 1936, reached a stage of 29.48 feet at gage on opposite bank (discharge, 215,000 second-feet), from information by Corps of Engineers. Flood of Mar. 

28, 1913, prior to construction of Sacandaga Reservoir and Troy Lock and Dam, reached 

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

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

by Corps of Engineers.

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

ancTthrough lock. Record of flow in bypass channel, which enters Hudson River 1? miles 

downstream, is shown separately. Flow appreciably regulated by Sacandaga Reservoir 

(see p. 283), Indian Lake Reservoir (see p. 279), and Delta, Hinckley, and Schoharie 

Reservoirs (combined capacity, 8,738,000,000 cubic feet). Diurnal fluctuation caused 

by power plants above station. Diversion above station for water supply for New York 

City (see records for Mohawk River at Cohoes and Schoharie Creek at Burtonsvilie). 

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

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

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

from) Oswego River Basin through summit level of Barge Canal near Rome.

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

Power Commission project.

Discharge, in second-feet, water year October 1948 to September 1949

286 HUDSON RIVER BASIN

Glens Falls feeder at Glens Falls, N. Y.

Location.--Water-stage recorder, lat. 43 0 17'30", long. 73°39'55", at upstream end of 

feeder canal at city of Glens Falls, Warren County. Auxiliary water-stage recorder 

1,000 feet downstream from cement mill and 3.3 miles downstream from base gage.

Records available (navigation seasons only). May 1927 to September 1949 in reports of 

ueoioglcal Survey. May 1919 to June 19'dl and October 1924 to September 1925 in reports

of State engineer and surveyor.

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

which are fair. Discharge computed by using fall, as determined by auxiliary waterstage recorder as a factor in conjunction with the shifting-control method. Flow regulated in accordance with requirements of Champlain Canal and for floating logs. Operation of feeder discontinued Dec. 4 and resumed Apr. 11; discharge record began 

Apr. 18. During period of no diversion, the feeder may carry a small flow representing 

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

1923 to September 1927 in files of State Department of Public Works.

Average discharge. 22 years (1927-49), 2,787 second-feet.

Extremes.--Maximurn discharge during year (river channel only), 17,300 second-feet Dec. 30 

(gage height, 14.56 feet); minimum (river channel only), 214 second-feet Aug. 18 (gage 

height, 3.75 feet); minimum daily (including canal), 551 second-feet Aug. 28.

1927-49: Maximum discharge (river channel only), 25,300 second-feet Oct. 3, 1945

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

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

(flowing south) and Lansing Kill and possibly from Chenango River Basin through Oriskany 

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

River Basin through summit level of Barge Canal near Rome. Diurnal fluctuation caused 

by power" plants and lock and dams on Barge Canal. Flow partly regulated by Delta and 

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

HUDSON RIVER BASIN 301 

Mohawk River at Cohoes, N. Y.

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

or Niagara Mohawk Power Corp., in Cohoes, Albany County.

Drainage area.--3,456 square miles.

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

plant of New York Power & Light Corp.) and October 1925 to September 1949. December 

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

6 at Crescent Dam).

Average discharge.--31 years (1918-49), 5,688 second-feet.

extremes.--Maximum discharge during year, 86,300 second-feet Dec. 31 (gage height, 20.18 

feet); minimum, 138 second-feet July 20 (gage height, 4.79 feet); minimum daily, 147 

second-feet June 19.

1925-49: Maximum discharge, 130,000 second-feet Mar. 19, 1936 (gage height, 22.57 

feet), from rating curve extended above 34,500 second-feet by logarithmic plotting; 

minimum, 6 second-feet Sept. 28, 1941 (gage height, 3.40 feet); minimum daily 23 secondfeet Aug. 24, 1941.

Remarks.--Records excellent. Records include small diversion just above gage for 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 Lensing 

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

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

level of Barge Canal near Rome. Most of flow of Schoharie Creek above Gilboa Dam, a 

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

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

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

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

Location. Water-stage recorder and concrete control, lat.'40°53'47", long. 74°23'36", 

i,t>uu feet downstream from dam of Boonton Reservoir, Eoonton, Morris County. Datum of 

gage is 195.68 feet above mean sea level (New Jersey Geological Survey bench mark).

Drainage area. 119 square miles.

Kecords available.--January 1906 to September 1949. March 1903 to February 1904 at site 

'I miles downstream.

Average discharge.--41 years (1906-11, 1913-49), 220 second-feet (adjusted).

.Extremes.--maximum discharge during the year, 2,370 second-feet Dec. 31 (gage height, 6.76 

reet, from floodmark in gage house), from rating curve extended above 1,200 second-feet 

by logarithmic plotting; minimum daily, 5.4 second-feet Sept. 10, 11, 26-2&.

1906-49: Maximum discharge, 3,770 second-feet Mar. 12, 1936 (gage height, 8.03 

feet), from rating curve extended above 1,200 second-feet by logarithmic plotting and 

by computation of discharge over Boonton Dam; practically no flow for many days. 

Maximum daily discharge recorded, 7,560 second-feet Oct. 10, 1903.

Remarks.--Records excellent except those for period of fragmentary gage-height record, 

which are good. Figures of daily and extreme discharge represent flow over control and 

effluent from sewage-disposal plant. Flow regulated by Boenton Reservoir (capacity. 

870,000,000 cable feet) and, since December 1948, by Splitrock Reservoir (capacity, 

442,000,000 cubic feet), 16*- miles above station. Water diverted from Eoonton Reservoir for municipal supply of Jersey City.

Cooperation.--Gage-height records for the station and for both of the reservoirs and 

record of sewage-disposal plant effluent furnished by Jersey City.

366 RARITAN RIVER BASIN

Millstone River near Kingston, N. J.

Location. --Water-stage recorder, lat. 40°23'05", long. 74°37'29", at Princeton sewage disposai plant, 1 mile north of Kingston, Middlesex County, and 1 mile downstream from 

Heathcote Brook. Datum of gage is 38.00 feet above mean sea level (New Jersey Geological Survey bench mark).

Drainage area.--173 square miles.

Records available.- May 1933 to September 1949 (discontinued).

Average discharge. --16 years, 239 second-feet.

Extremes . --Maximum discharge during year, 7,230 second-feet Dec. 30 (gage height, 12.86 

I'eet, from floodmark in gage house), from rating curve extended above 4,100 second-feet 

by logarithmic plotting; minimum daily, 22 second-feet Aug. 28.

1933-49: Maximum discharge, 9,820 second-feet Sept. 21, 1938 (gage height, 14.12 

feet, from floodmark in , gage house) from rating curve extended above 4,100 second-feet 

by logarithmic plotting; minimum daily, about 2 second-feet Aug. 21, 23, Sept. 5, 7, 1944.

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

water was probably interchanged between river and Delware & Raritan Canal above station. 

Flow slightly regulated by Lake Carnegie, 2 miles above station, and at low flow, by

girstmill.

Cooperation. --Water-stage recorder inspected by employee of borough of Princeton.

Note. No gage-height record June 18, 19, _3-30, July 1-12, 26-31, Aug. 1-4, 9-28, Sept. 21} discharge computed on basis of 2 discharge measurements, occasional staff-gage readings, and records 

for Millstone River at Blaekwells Mills and Assumpink Creek at Trenton.
RARITAN RIVER BASIN 3u? 

Millstone River at Blackwells Mills, N. J.

Location. Water-stage recorder and concrete control, lat. 40°28'30", long. 74 C 34'34", at 

highway bridge at Blaclcwells' Mills, Somerset County, a quarter of a mile downstream from 

Middlebrush Brook. Datum of gage is 26.97 feet above mean sea level, datum of 1929.

Drainage area. 258 square miles.

Kecprds available. August 1921 to September 1949. June 1903 to December 1904 (gage 

heights only) at site at Millstone, if miles downstream.

Average discharge. 27 years (1922-49), 369 second-feet.

Extremes. Maximum discharge during year, 14,000 second-feet Dec. 31 (gage height, 13.84 

feet), from rating curve extended above 4,000 second-feet on basis of slope-area determination at gage height 15.29 feet; minimum, 25 second-feet Sept. 21, 22 (gage height, 

1.31 feet).

1921-49: Maximum discharge, 18,300 second-fee Sept. 21, 1938 (gage height, 15.29 

feet, from floodmark), by slope-area method; minimum, about 5 second-feet Sept. 16, 

1923.

Remarks.--Records excellent except those above 900 second-feet and those for period of ice 

errect, which are good, and those for period of no gage-height record, which are poor. 

Water was probably interchanged between river and Delware & Raritan Canal.

Drainage area.--34.4 square miles.

Kecprds available.--May 1927 to September 1949. June 1922 to December 1926 at site at

~Patricks corner, 2^ miles upstream.

Average discharge.--21 years (1928-49), 37.5 second-feet (adjusted).

Extremes.--Maximum discharge during year, 944 second-feet Dee. 31 (gage height, 25.51 

I'eet), from rating curve extended above 400 second-feet on basis of weir formula; no 

flow for many days when blow-off gates were closed and water was below spillway.

1927-49: Maximum discharge, 2,660 second-feet Sept. 21, 1938 (gage height, 26.18 

feet), from rating curve extended above 400 second-feet on basis of weir formula; no 

flow at times when gates in dam1 were closed and there was no flow over spillway.

Remarks.--Records good except those for periods when blow-off gates were open, which are 

fair. Figures of discharge include flow over dam and through blow-off gates. Flow 

regulated by Farrington Reservoir (capacity, 87,600,000 cubic feet).

Cooperation.--Water-stage recorder inspected and records of openings of blow-off gates 

1'urnished by employee of city of Hew Brunswick.

388 DELAWARE RIVER BASIN

Delaware River at Port Jervis, N. Y.

Location.--Water-stage recorder, lat. 41 0 22'20", long. 74°41'50", near highway bridge at

Fort Jervis, Orange County, 1^ miles upstream from Neversink River. Datum of gage is

415.35 feet above mean sea level, datum of 1929. 

Drainage area.--3,076 square miles. 

Hecords available. October 1904 to September 1949. 

Average discharge. 45 years, 5,529 second-feet. 

Extremes.--Maximum discharge during year, 87,800 second-feet Dec. 31 (gage height, 14.07

feet), from rating curve extended above 47,000 second-feet by logarithmic plotting;

minimum, 300 second-feet Aug. 29 (gage height, 0.83 foot, from graph based on normal

recession and records for station at Montague, N. J.); minimum daily, 380 second-feet

Aug. 29 (gage height, 1.00 foot).

1904-49: Maximum discharge, 140,000 second-feet May 23, 1942 (gage height, 17.76

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

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

second-feet Sept. 23, 1908.

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

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

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

8, 1904 (Ice jam). 

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

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

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

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

feet). 

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

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

Bridge Reservoirs.

408 DELAWARE RIVER BASIN

Cold Spring Brook at China, N. Y.

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

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

Sanford. Datum of gage is 1,490.76 feet above mean sea level, adjustment of 1912 (levels by Corps of Engineers).

Drainage area.--1.51 square miles.

Records available. October 1934 to September 1949.

Average discharge. 14 years (1935-49), 2.64 second-feet.

Extremes.--Maximum discharge during year, 53.0 second-feet Dec. 30 (gage height, 3.19

reet), from rating curve extended above 17 second-feet on basis of logarithmic plotting; 

minimum, 0.014 second-foot Aug. 27, 28 (gage height, 1.11 feet).

1934-49: Maximum discharge, 335 second-feet Oct. 30, 1935 (gage height, 4.5 feet, 

from floodmarks), from rating curve extended above 55 second-feet on basis of theoretical rating; minimum, 0.007 second-foot Aug. 31, 1944; minimum gage height, 1.075 feet 

Aug. 3, 1936.

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

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

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

flow. In addition to records of stream flow, records of rainfall, temperature, and 

ground-water levels are collected. Weekly records of ground-water elevations for 1949 

are published in Water-Supply Paper 1156.

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

obstructed intake, which are fair. This station is operated in connection with a 

study of the effect of reforestation on stream flow. In addition to records of stream 

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

Weekly records of ground-water levels for 1949 are published in Water-Supply Paper 

1156.

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

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

reforestation on stream flow. In addition to records of stream flow, records of precipitation, temperature, barometric pressure, soil temperature, evaporation, and 

ground-water levels are collected. Weekly records of ground-water levels for 1949 

are published in Water-Supply Paper 1156.

SUSQUEHANNA RIVER BASIN 

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

523

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

150 Teet upstream from Erie Railroad bridge in Hornell, Steuben County, 0.25 mile upstream from Crosby Creek, and 1.5 miles downstream from Canacadea Creek. Datum of gage 

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

Drainage area. 159 square miles.

Records available. August 1942 to September 1949.

Extremes. Maximum discharge during year, 2,220 second-feet Feb. 15 (gage height, 7.66 

reet); minimum daily, 15 second-feet July 8, 9, 12, 16, 17, 20-23, Sept. 15-17.

1942-49: Maximum discharge, 9,340 second-feet May 26, 1943 (gage height, 13.30 

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

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

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

or, sliif ting-control, which are fair. Records include daily diversion (2 to 4 secondfeet) just above control by Erie Railroad Co. An unknown but relatively small amount 

of water diverted is returned to stream above control. City of Hornell diverts an 

average of about 3.5 second-feet for municipal supply from Carrington Creek, a tributary above station; sewage enters river below gage. Since November 1939, flood flows 

affected by Arkport Reservoir.

Discharge, in second-feet, water year October 1948 to September 1949

Frankstown Branch Juniata River at Huntingdon, Pa.

Location. Water-stage recorder, lat. 40°29'05", long. 78°01ilO", 450 feet downstream 

from Smithfield Bridge at Huntingdon, Huntingdon County, and 0.8 mile upstream from 

Standing Stone Creek. Datum of gage is 599.69 feet above mean sea level, datum of 

1929, New York-Pennsylvania supplementary adjustment of 1943.

Drainage area. 816 square miles.

Records available.--September 1941 to September 1949 in reports of Geological Survey. 

May 1895 to September 1914 and October 1920 to February 1923 (gage heights and discharge measurements only), September 1941 in reports of Pennsylvania Department of 

Forests and Waters. May 1895 to December 1938 (gage heights only) in reports of U. 

S. Weather Bureau. Records prior to October 1914 obtained at Fourth Street Bridge, 

2,000 feet downstream.

Average discharge . 26 years (1895-98, 1899-1914, 1941-49), 1,127 second-feet.

Extremes. Maximum discharge during year, 7,720 second-feet Dec. 30 (gage height, 6.99 

reet); minimum, 44 second-feet Oct. 16 (gage height, 0.53 foot); minimum daily, 218 

second-feet Oct. 2,

1895-1938, 1941-49: Maximum discharge, 81,000 second-feet Mar. 18, 1936 (gage 

height, 21.87 feet, from floodmark), from rating curve extended above 20,000 secondfeet on basis of computation of flow over dam; minimum observed, 14 second-feet Feb. 

1948 (gage height, 0.27 foot).

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

for periods of shifting control, which are poor. Some diurnal regulation by hydroelectric plant above station. Records of chemical analyses ani water temperatures 

for water year 1949 are given in Water-Supply Paper 1162.

638 POTOMAC RIVER BASIN

Big Spring at Masonville, W. Va.

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

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

of gage, 1,580 feet (from topographic map).

Records available.--August 1945 to September 1949.

Extremes.--Maximum discharge during year, 600 second-feet June 18 (gage height, 2.68 feet), 

from rating curve extended above 100 second-feet by logarithmic plotting; minimum, 7.9 

second-feet Oct. 1-5 (gage height, 0.83 foot).

1945-49: Maximum discharge, that of June 18, 1949; minimum, 4.9 second-feet Oct. 

6-8, 1947.

Remarks.--Records good except those above 40 second-feet and those for periods of no gageheight record, which are fair. Big Spring, which emerges at several places from 50 to 

300 feet above gage, is the source of entire flow except during wet weather when surface drainage from half a square mile enters the stream above gage. Plow from surface 

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

Discharge, in second-feet, water year October 1948 to September 1949

Rappahannock River near Fredericksburg, Va.

Location. Water-stage recorder, lat. 38°19', long. 77°31', ij miles upstream from dam of 

Virginia Electric & Power Co., 2£ miles downstream from Motts Run, and 85 miles upstream from Fredericksburg, Spotsylvania County. Datum of gage is 56.18 feet above mean 

sea level, datum of 1929, Culpeper supplementary adjustment of 1943.

Drainage area. 1,599 square miles.

Kecords available. September 1907 to September 1949.

Average discharge. 42 years, 1,693 second-feet.

Extremes. Maximum discharge during year, 37,400 second-feet Dec. 4 (gage height, 11.34 

feet); minimum, 614 second-feet Oct. 5 (gage height, 1.49 feet).

1907-49: Maximum discharge, 140,000 second-feet Oct. 16, 1942 (gage height, 25.9 

feet, from floodmarks), from rating curve extended above 70,000 second-feet on basis of 

determinations of flow over dam and slope-area determinations at gage heights 25.1 and 

25.9 feet; minimum, 5 second-feet Oct. 11, 12, 1930 (gage height, -0.23 foot). 

Flood of June 1889 was probably several feet lower than flood of October 1942.

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

which are fair.

Revisions (water years). W 801: 1924(M). ¥951: 1937(M).
