NOTICE - January 13, 2017 - The NY Water Science Center is transitioning to a new data management software package. While you may not have noticed this transition, some sites may have problems or delays in being updated. We are actively monitoring these conditions and are resolving them as quickly as possible. Thank you for your patience!

LOCATION.--Lat 41°26'28", long 74°36'07" referenced to North American Datum of 1983, Orange County, NY, Hydrologic Unit 02040104, on right bank just upstream from bridge on Guymard Turnpike, 0.5 mi downstream from Basher Kill, 0.8 mi southeast of Godeffroy, 1.7 mi south of Cuddebackville, and 8.5 mi upstream from mouth.
DRAINAGE AREA.--307 mi2.
PERIOD OF RECORD.--Gage heights and discharge measurements, August to October 1903 and August 1909 to April 1914, and twice-daily figures of discharge for January 1911 to December 1912 (which do not represent daily mean discharges because of diurnal fluctuation) are published in WSP 97, 261, 321, 351, and 381. July 1937 to current year. August to October 1903, published as "Navesink River at Godeffroy, NY."
REVISED RECORDS.--WSP 1502: 1951(M). WDR NY-82-1: Drainage area. WDR NY-87-1: 1986. WDR-US-2007: 2006.
GAGE.--Water-stage recorder and crest-stage gage. Datum of gage is 459.66 ft above NGVD of 1929 (levels by Corps of Engineers). Prior to Apr. 30, 1914, nonrecording gages at same site (August to October 1903 at datum 0.98 ft higher).
REMARKS.--Prior to 1949, diurnal fluctuation at low and medium flow caused by powerplant at Cuddebackville. 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 releases and spill) impounded for release during periods of low flow in the lower Delaware River basin, as directed by the Delaware River Master. Occasional regulation by Pleasure Lake at South Fallsburg. Water Year 2014: Records good. Water Year 2015: Records good except those for estimated daily discharges, which are poor.
EXTREMES FOR PERIOD OF RECORD.--Maximum discharge, since construction of Neversink Reservoir in 1953, 33,000 ft3/s, Aug. 19, 1955, gage height, 12.49 ft; minimum discharge not determined.
EXTREMES FOR PERIOD PRIOR TO REGULATION.--Maximum discharge, prior to construction of Neversink Reservoir in 1953, 24,500 ft3/s, Nov. 26, 1950, gage height, 11.79 ft; minimum observed, no flow July 21, 22, 28, 1911, result of regulation.
