LOCATION.--Lat
41°28'31", long 74°54'46" referenced to North
American Datum of 1927, Pike County, PA, Hydrologic Unit 02040104, at
Shohola-Barryville Bridge at Barryville, just upstream from Halfway
Brook, and 1,000 ft upstream from Shohola Creek.
DRAINAGE AREA.--2,659 mi².
PERIOD OF RECORD.--October 2018 to current year.
GAGE.--Water-stage recorder. Datum of gage is 559.78 ft above
NGVD of 1929.
REMARKS.--Flow regulated by Prompton Reservoir (station
01428900), General Edgar Jadwin Reservoir (station 01429400), and Lake
Wallenpaupack (station 01431700). Large diurnal fluctuations at medium
and low flows caused by powerplants on tributary streams. Subsequent to
September 1954, entire flow from 371 mi² of drainage area controlled by
Pepacton Reservoir (station 01416900), and subsequent to October 1963,
entire flow from 454 mi² of drainage area controlled by Cannonsville
Reservoir (station 01424997). Part of flow from these reservoirs
diverted for New York City municipal supply. 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.
PERIOD OF DAILY RECORD1.--WATER TEMPERATURE: October
1967 to September 1973, March 1975 to current year.
INSTRUMENTATION1.--Water-temperature satellite
telemeter provides 15-minute-interval readings. From March 1975 to
February 1994, water-temperature recorder provided one-hour-interval
readings. Prior to September 1973, water-temperature recorder provided
continuous recordings.
REMARKS1.--Temperature readings prior to Oct. 1,
2007, rounded to the nearest 0.5 °C. Unpublished records of daily
temperatures for May to September 1964-66 are available in files of the
Geological Survey.
EXTREMES FOR PERIOD OF DAILY RECORD1.--WATER
TEMPERATURE: Prior to Oct. 1, 2007--Maximum (water years 1968-73,
1976-78, 1980-82, 1986-88, 1990-2002, 2004-07), 32.0 °C, July 20, 21,
1980; minimum, 0.0 °C on many days during winter periods.
WATER TEMPERATURE: After Oct. 1, 2007--Maximum, 29.8 °C, July 7, 2010;
minimum, -0.1 °C on several days during 2008, 2010, and 2014 winter
periods, Feb. 22, 23, 24, 26, 2011, Jan. 22, 23, 2012.

ICE EFFECTS
ON STREAMFLOW -- During cold weather, stage and discharge values may be
affected by ice at some streamgages. Streamgages experiencing ice
conditions will have the discharge record temporarily disabled to
prevent the display of erroneous discharge values. Display of discharge
record will resume when it is determined that ice conditions are no
longer present. Adjustment of data affected by ice can only be done
after detailed analysis.
