    This station is operated in cooperation with:
       National Weather Service
       New York City Department of Environmental Protection
       U.S. Geological Survey


    LOCATION.--Lat 41°58'23", long 75°10'27" referenced to North American Datum of 1983, Delaware County, NY, Hydrologic Unit 02040102, on right bank 3,000 ft upstream from bridge on County Highway 28 at Fishs Eddy, 0.6 mi upstream from Fish Creek, 4.2 mi downstream from Beaver Kill, and 11 mi upstream from the confluence of East and West Branches near Hancock. Water-quality sampling site at discharge station.
    DRAINAGE AREA.--784 mi2.
    PERIOD OF RECORD.--October 1912 to current year. October 2001 through September 2004 published as East Branch Delaware River above Read Creek at Fishs Eddy (station 01420980). Monthly discharge only for some periods, published in WSP 1302.
    REVISED RECORDS.--WDR NY-82-1: Drainage area.
    GAGE.--Water-stage recorder and crest-stage gage. Datum of gage is 955.96 ft above NGVD of 1929. Prior to Sept. 27, 1928, nonrecording gage, and Sept. 28, 1928 to Nov. 1, 1967, water-stage recorder, at site 3,000 ft downstream at datum 5.0 ft lower. Nov. 2, 1967 to Sept. 30, 2001, at site on left bank at same datum, and Oct. 1, 2001 to Sept. 30, 2004, at site 0.30 mi upstream at same datum.
    REMARKS.--Records fair except those for estimated daily discharges, which are poor. Subsequent to September 1954, entire flow from 371 mi2 of drainage area controlled by Pepacton Reservoir (station 01416900). Part of flow 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. Satellite and telephone gage-height and temperature telemeter at station.
    EXTREMES FOR PERIOD OF RECORD.--Maximum discharge since construction of Pepacton Reservoir, 77,400 ft3/s, June 28, 2006, gage height, 21.43 ft, from rating curve extended above 29,000 ft3/s; minimum discharge, 52 ft3/s, July 23, 1964, gage height, 1.16 ft, site and datum then in use.
    EXTREMES OUTSIDE PERIOD OF RECORD.--Flood of Oct. 9, 1903, reached a stage of 23.6 ft, at site 3,000 ft downstream at datum 5.0 ft lower, from description obtained in April 1939, from local residents who had experienced the flood (discharge, about 70,000 ft3/s, from rating curve extended above 22,000 ft3/s).
    EXTREMES FOR PERIOD PRIOR TO REGULATION.--Maximum discharge prior to construction of Pepacton Reservoir, 53,300 ft3/s, Aug. 24, 1933, gage height, 20.60 ft, site and datum then in use, from rating curve extended above 22,000 ft3/s; minimum daily discharge, 68 ft3/s, Aug. 28, 1949; minimum instantaneous discharge not determined.
    PERIOD OF DAILY RECORD1.--WATER TEMPERATURE: November 1967 to current year. From October 2001 to September 2004, published as East Branch Delaware River above Read Creek at Fishs Eddy (station 01420980).
    INSTRUMENTATION1.--Water-temperature satellite and telephone telemeter provides 15-minute-interval readings. Prior to June 1993, water-temperature recorder since October 1975, provided one-hour-interval readings. Prior to October 1975, water-temperature recorder provided continuous recordings.
    EXTREMES FOR PERIOD OF DAILY RECORD1.--WATER TEMPERATURE: Prior to Oct. 1, 2007--Maximum (water years 1968-75, 1978, 1980-82, 1984, 1986-95, 1999-2003, 2005-07), 31.5 °C, Aug. 2, 1975; minimum (water years 1968-76, 1978-79, 1981-2007), 0.0 °C on many days during winter periods, except 1978.
    WATER TEMPERATURE: After Oct. 1, 2007--Maximum, 27.6 °C, July 18, 2013; minimum, -0.1 °C, Jan. 2, 3, 2013.
