Click to hidestation-specific text

This station is operated in cooperation with:
   NYS Department of Environmental Conservation


LOCATION.--Lat 41°52'02", long 75°12'50" referenced to North American Datum of 1983, Wayne County, PA, Hydrologic Unit 02040101, on right bank at Lordville-Equinunk Interstate Bridge at Lordville, 9.7 mi southeast of Hancock. Water-quality sampling site at discharge station.
DRAINAGE AREA.--1,590 mi2.
PERIOD OF RECORD.--Maximum only--June 2006, July 2006 to current year.
REVISED RECORDS.--WDR NY-82-1: Drainage area.
GAGE.--Water-stage recorder and crest stage gage. Datum of gage is 835.00 ft above NGVD of 1929.
REMARKS.--Records good except those for estimated daily discharges, which are poor. 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. Satellite and telephone gage-height and temperature telemeter at station.
EXTREMES FOR PERIOD OF RECORD.--Maximum discharge 126,000 ft3/s, June 28, 2006, gage height, 28.87 ft, from floodmark, from rating curve extended above 39,000 ft3/s on basis of runoff comparisons with nearby stations; minimum discharge, 371 ft3/s, Sept. 6, 2008, Sept. 28, 2010; minimum gage height, 5.37 ft, Sept. 28, 2010.
EXTREMES OUTSIDE PERIOD OF RECORD.--Maximum discharge, 95,600 ft3/s, Sept. 18, 2004, gage height, 23.53 ft, from floodmark, and 102,000 ft3/s, Apr. 3, 2005, gage height, 25.20 ft, from floodmark, both by runoff comparisons with nearby stations.
PERIOD OF DAILY RECORD1.--WATER TEMPERATURE: October 1967 to August 1971, June 1973 to May 1996, July 2006 to current year.
INSTRUMENTATION1.--Water-temperature satellite and telephone telemeter provides 15-minute-interval readings. From June 1987 to June 1989, water-temperature satellite telemeter provided one-hour-interval readings. From June 1973 to November 1989, water-temperature recorder provided one-hour-interval readings. Prior to August 1971, water-temperature recorder provided continuous recordings.
EXTREMES FOR PERIOD OF DAILY RECORD1.--WATER TEMPERATURE: Prior to Oct. 1, 2007--Maximum (water years 1968-70, 1973, 1975-86, 1989, 1991-95, 2007), 30.5 °C, June 16, 1976, July 10, 1981; minimum (water years 1968-71, 1974, 1977-78, 1980-96, 2007), 0.0 °C on many days during winter period.
WATER TEMPERATURE: After Oct. 1, 2007--Maximum, 27.4 °C, June 10, 2008; minimum, 0.0 °C on many days during winter period in 2011 and 2013 water years.
