[!] ICE EFFECTS ON STREAMFLOW -- During cold weather, stage and discharge values may be affected by ice at some streamgages. Streamgages experiencing ice conditions will have the discharge record temporarily disabled to prevent the display of erroneous discharge values. Display of discharge record will resume when it is determined that ice conditions are no longer present. Adjustment of data affected by ice can only be done after detailed analysis.

USGS 01427510 DELAWARE RIVER AT CALLICOON NY

PROVISIONAL DATA SUBJECT TO REVISION

Click to hidestation-specific text

 

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.
