This station is operated in cooperation with:
   New York Power Authority
   NYS Department of Environmental Conservation


LOCATION.--Lat 42°32'13", long 74°24'38" referenced to North American Datum of 1983, Schoharie County, NY, Hydrologic Unit 02020005, on left bank 100 ft downstream from bridge on State Highway 30, 0.9 mi north of Breakabeen, and 1.1 mi downstream from Keyser Kill.
DRAINAGE AREA.--444 mi2.
PERIOD OF RECORD.--July 1975 to current year.
REVISED RECORDS.--WDR NY-81-1: 1980(M). WDR NY-90-1: Drainage area. WDR-US-2011: 1996.
GAGE.--Water-stage recorder and crest-stage gage. Datum of gage is 686.79 ft above NGVD of 1929 (Soil Conservation Service benchmark).
REMARKS.--Records fair. Considerable regulation of flow by Blenheim-Gilboa Pumped Storage Project about 8 mi upstream. Entire flow, runoff from 315 mi2, except for periods of spill, diverted from Schoharie Reservoir through Shandaken Tunnel into Esopus Creek upstream from Ashokan Reservoir for water supply of City of New York. For days of reservoir outflow greater than 10 ft3/s, see station 01350101. Satellite gage-height telemeter at station.
EXTREMES FOR PERIOD OF RECORD.--Maximum discharge, 134,000 ft3/s, Aug. 28, 2011, gage height, 22.37 ft, outside gage height was 23.47 ft, from floodmarks, from rating curve extended above 27,000 ft3/s on basis of contracted-opening and flow-over-road measurement at gage height about 19.5 ft and runoff comparisons of peak flow with nearby stations; minimum discharge, 1.7 ft3/s, Oct. 14, 1980; minimum gage height, 0.25 ft, Sept. 26, 1985.
