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


LOCATION.--Lat 42°01'28.5", long 75°07'09.4" referenced to North American Datum of 1983, Delaware County, NY, Hydrologic Unit 02040102, on right bank 800 ft downstream from Baxter Brook, and 1,100 ft downstream from Harvard Road bridge at Harvard. Water-quality sampling site at discharge station.
DRAINAGE AREA.--458 mi2.
PERIOD OF RECORD.--October 1934 to June 1967, November 1977 to current year.
REVISED RECORDS.--WDR NY-82-1: Drainage area. WDR NY-84-1: 1978-81(M).
GAGE.--Water-stage recorder and crest-stage gage. Datum of gage is 1,007.41 ft above NGVD of 1929. Prior to Aug. 12, 1958, at site 1,100 ft upstream at datum 0.65 ft higher, and from Aug. 12, 1958 to June 30, 1967, at site 200 ft downstream at same datum.
REMARKS.--Records good 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, 22,100 ft3/s, June 28, 2006, gage height, 16.61 ft; minimum discharge, 7.2 ft3/s, Oct. 13, 1954, gage height, 1.63 ft, site and datum then in use.
EXTREMES FOR PERIOD PRIOR TO REGULATION.--Maximum discharge prior to construction of Pepacton Reservoir, 31,400 ft3/s, Sept. 22, 1938, gage height, 16.93 ft, site and datum then in use, from rating curve extended above 20,000 ft3/s on basis of slope-area measurement at gage height 15.58 ft, datum then in use.
PERIOD OF DAILY RECORD1.--WATER TEMPERATURE: June 1978 to current year.
INSTRUMENTATION1.--Water-temperature satellite and telephone telemeter provides 15-minute-interval readings. Prior to June 1994, water-temperature recorder provided one-hour interval readings.
EXTREMES FOR PERIOD OF DAILY RECORD1.--WATER TEMPERATURE: Prior to Oct. 1, 2007--Maximum (water years 1978, 1981-82, 1984-2007), 28.0 °C, June 30, 1981; minimum (water years 1979-87, 1989-2007), 0.0 °C on many days during winter periods, except 1989, 1998.
WATER TEMPERATURE: After Oct. 1, 2007--Maximum, 22.8 °C, June 10, 2008, July 18, 2010, June 21, 2012; minimum, -0.2 °C, Feb. 11, 29, 2008.
