LOCATION.--Lat
41°45'24.3", long 75°03'26.7" referenced to North
American Datum of 1983, Wayne County, PA, Hydrologic Unit 02040101, on
right bank 0.5 mi downstream from Callicoon Creek, 0.5 mi downstream
from Interstate Bridge 7, and 0.8 mi southeast of Callicoon.
DRAINAGE AREA.--1,820 mi².
PERIOD OF RECORD.--June 1975 to current year.
REVISIONS HISTORY.--WDR NY-82-1: Drainage area. WDR NY-86-1:
1975-84 (M). WDR NY-04-1: 2003.
GAGE.--Water-stage recorder and crest-stage gage. Datum of gage
is 734.88 ft above NGVD of 1929 and 734.33 ft above NAVD of 1988
(VERTCON).
REMARKS.--Entire flow from 371 mi² of drainage area controlled
by Pepacton Reservoir (station 01416900), and entire flow from 454 mi²
of drainage area controlled by Cannonsville Reservoir (station
01424997). Part of flow from 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 2014-18: Records good except those for estimated daily
discharges, which are poor.
EXTREMES FOR PERIOD OF RECORD.--Maximum discharge, 144,000
ft³/s, June 28, 2006, gage height, 20.38 ft; minimum discharge, 306
ft³/s, Sept. 24, 25, 1997; minimum gage height, 2.20 ft, Sept. 13,
1977, Aug. 23, 1985.
PERIOD OF DAILY RECORD1.--SPECIFIC CONDUCTANCE: June
2012 to March 2014, December 2014 to current year.
WATER TEMPERATURE: June 1975 to current year.
INSTRUMENTATION1.--Water-temperature and
specific-conductance satellite and telephone telemeter provides
15-minute-interval readings. Prior to May 1989, water-temperature
recorder provided one-hour-interval readings.
REMARKS1.--Temperature readings prior to Oct. 1,
2007, rounded to the nearest 0.5 °C. Water temperature is affected by
release of water from upstream reservoirs. Interruption of record was
due to malfunction of recording instrument. Specific conductance
records considered poor in water years 2015-17.
EXTREMES FOR PERIOD OF DAILY RECORD1.--SPECIFIC
CONDUCTANCE: Maximum, 252 uS/cm at 25 °C, July 5, 6, 2018;
minimum, 34 uS/cm at 25 °C, June 28, 2013. WATER TEMPERATURE: Prior to
Oct. 1, 2007--Maximum (water years 1976-2007), 30.5 °C, July 12, 1987;
minimum, 0.0 °C on many days during winter periods. WATER TEMPERATURE:
After Oct. 1, 2007--Maximum, 30.4 °C, July 7, 2010; minimum, -0.3 °C,
Dec. 2, 2007.
