    This station is operated in cooperation with:
       NYS Department of Environmental Conservation
       Pennsylvania Department of Environmental Protection


    LOCATION.--Lat 41°45'24", long 75°03'27" referenced to North American Datum of 1983, Wayne County, PA, Hydrologic Unit 02040101, on right bank 0.5 mi downstream from Callicoon Creek, 0.5 mi downstream from Interstate Bridge 7, and 0.8 mi southeast of Callicoon. Water-quality sampling site at discharge station.
    DRAINAGE AREA.--1,820 mi2.
    PERIOD OF RECORD.--June 1975 to current year.
    REVISED RECORDS.--WDR NY-82-1: Drainage area. WDR NY-86-1: 1975-84 (M). WDR NY-04-1: 2003.
    GAGE.--Water-stage recorder and crest-stage gage. Datum of gage is 734.88 ft above NGVD of 1929.
    REMARKS.--Records good except those for estimated daily discharges, which are poor. Entire flow from 371 mi2 of drainage area controlled by Pepacton Reservoir (station 01416900), and 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. Satellite and telephone gage-height and temperature telemeter at station.
    EXTREMES FOR PERIOD OF RECORD.--Maximum discharge, 144,000 ft3/s, June 28, 2006, gage height, 20.38 ft; minimum discharge, 306 ft3/s, Sept. 24, 25, 1997; minimum gage height, 2.20 ft, Sept. 13, 1977, Aug. 23, 1985.
    PERIOD OF DAILY RECORD1.--SPECIFIC CONDUCTANCE: June 2012 to current year.
    WATER TEMPERATURE: June 1975 to current year.
    INSTRUMENTATION1.--Water-temperature and specific-conductance satellite and telephone telemeter provides 15-minute-interval readings. Prior to May 1989, water-temperature recorder provided one-hour-interval readings.
    EXTREMES FOR PERIOD OF DAILY RECORD1.--SPECIFIC CONDUCTANCE: Maximum, 111 uS/cm, Apr. 28, 2013; minimum, 34 uS/cm, June 28, 2013.
    WATER TEMPERATURE: Prior to Oct. 1, 2007--Maximum (water years 1976-2007), 30.5 °C, July 12, 1987; minimum, 0.0 °C on many days during winter periods.
