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°30'32", long 74°59'09" referenced to North American Datum of 1983, Sullivan County, NY, Hydrologic Unit 02040101, on left bank 1.6 mi upstream from Lackawaxen River, and 4.6 mi northwest of Barryville.
DRAINAGE AREA.--2,020 mi2.
PERIOD OF RECORD.--October 1940 to current year.
REVISED RECORDS.--WDR NY-82-1: Drainage area. WDR NY-04-1: 2003.
GAGE.--Water-stage recorder and crest-stage gage. Datum of gage is 600.22 ft above NGVD of 1929.
REMARKS.--Subsequent to September 1954, entire flow from 371 mi2 of drainage area controlled by Pepacton Reservoir (station 01416900), and subsequent to October 1963, entire flow from 454 mi2 of drainage area controlled by Cannonsville Reservoir (station 01424997). Part of flow of 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. Water Years 2014-15: Records good except those for estimated daily discharges, which are poor.
EXTREMES FOR PERIOD OF RECORD.--Maximum discharge prior to current degree of regulation, 130,000 ft3/s, Aug. 19, 1955, gage height, 26.40 ft, from floodmarks in gage house, from rating curve extended above 57,000 ft3/s on basis of slope-area measurement at gage height 23.19 ft; maximum discharge since current degree of regulation, 151,000 ft3/s, June 28, 2006, gage height, 28.97 ft, from floodmark in gage house, from rating curve extended as explained above; minimum discharge, 122 ft3/s, Sept. 5, 1953, gage height, 1.11 ft.
PERIOD OF DAILY RECORD1.--WATER TEMPERATURE: October 1967 to current year (no winter record for water years 1969-76).
INSTRUMENTATION1.--Water-temperature satellite and telephone telemeter provides 15-minute-interval readings. From October 1975 to September 1995, water-temperature recorder provided one-hour-interval readings. Prior to October 1975, water-temperature recorder provided continuous readings.
REMARKS1.--Temperature readings prior to Oct. 1, 2007, rounded to the nearest 0.5 °C.
EXTREMES FOR PERIOD OF DAILY RECORD1.--WATER TEMPERATURE: Prior to Oct. 1, 2007--Maximum (water years 1968-75, 1980-81, 1983, 1985-96, 1998-2001, 2003-07), 32.5 °C, July 9, 10, 1993; minimum (water years 1968, 1977-2007), 0.0 °C, on many days during winter periods, each year except water years 1980-82.
WATER TEMPERATURE: After Oct. 1, 2007--Maximum, 32.0 °C, July 7, 8, 2010; minimum (water years 2008, 2010-15), -0.1 °C, Feb. 13, 2012, many days during 2013 winter period, Dec. 22, 26, 2013, and several days during 2015 winter period.
