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

LOCATION.--Lat 41°49'12", long 74°38'08" referenced to North American Datum of 1983, Sullivan County, NY, Hydrologic Unit 02040104, on right bank at downstream end of outlet channel, 1,650 ft downstream from Neversink Dam and State Highway 55, 2.0 mi southwest of Neversink, and 2.6 mi upstream from Wynkoop Brook.
DRAINAGE AREA.--92.6 mi2.
PERIOD OF RECORD.--October 1941 to current year.
REVISED RECORDS.--WDR NY-72-1: 1961 (M), 1968 (M). WDR NY-82-1: Drainage area.
GAGE.--Water-stage recorder and concrete control. Datum of gage is 1,255.24 ft above NGVD of 1929 (levels by Board of Water Supply, City of New York). Prior to Jan. 17, 1953, at site 650 ft downstream at datum 0.20 ft lower. Jan. 17, 1953 to Apr. 16, 1954, at present site at datum 0.41 ft higher.
REMARKS.--Records good. Subsequent to June 1953, entire flow from 92.5 mi2 of drainage area controlled by Neversink Reservoir (station 01435900). Part of flow diverted for New York City municipal supply. Remainder of flow (except for conservation release and spill) impounded for release during periods of low flow in the lower Delaware River basin, as directed by the Delaware River Master. Satellite gage-height telemeter at station.
EXTREMES FOR PERIOD OF RECORD.--Maximum discharge since construction of Neversink Reservoir, 12,300 ft3/s, Apr. 3, 2005, gage height, 12.99 ft, outside gage height was about 14.8 ft, from floodmark, from rating curve extended above 6,000 ft3/s; no flow for all or part of each day Sept. 22-24, Oct. 26-29, 1954.
EXTREMES FOR PERIOD PRIOR TO REGULATION.--Maximum discharge prior to construction of Neversink Reservoir, 22,300 ft3/s, Nov. 25, 1950, gage height, 11.23 ft, site and datum then in use, from rating curve extended above 2,600 ft3/s on basis of contracted-opening and critical-depth measurements of peak flow; maximum gage height, 11.65 ft, Sept. 27, 1942, site and datum then in use.

Peak Flow and Stage Information

USGS provisional real-time discharge data can differ from NYCDEP discharge data at flows less than 300 ft3/s as a result of debris or other obstructions affecting the USGS stage-discharge relationship. USGS and NYCDEP data may also differ as a result of accuracy limitations of the stage-discharge rating and the release valve ratings. Release valve changes are recorded at the stream-gaging station after a brief period due to travel time between the two locations.
