ADDITIONAL INFORMATION

STATION.--01474500 SCHUYLKILL RIVER AT PHILADELPHIA, PA (National stream-quality accounting network station)
LOCATION.--Lat 39`58'04", long 75`11'20", Philadelphia County, Hydrologic Unit 02040203, on right bank 150 ft upstream from Fairmount Dam, 1,500 ft upstream from bridge on Spring Garden Street in Philadelphia, and 8.7 mi upstream from mouth. Water-quality sampling site 1.6 mi upstream.
DRAINAGE AREA.--1,893 mi2.
PERIOD OF RECORD.--October 1931 to current year. Records for January 1898 to December 1912, published in WSP 35, 48, 65, 82, 97, 125, 166, 202, 214, 261, 301, and 381 have been found to be unreliable and should not be used.
GAGE.--Water-stage recorder and concrete control. Datum of gage is 5.74 ft above sea level. Prior to Nov. 25, 1956, water-stage recorder at site on right bank just upstream from Fairmount Dam at same datum. Nov. 26, 1956, to Oct. 6, 1966, water-stage recorder at site on left bank 40 ft upstream from Fairmount Dam at same datum.
EXTREMES OUTSIDE PERIOD OF RECORD.--Flood of Oct. 4, 1869 reached a stage of 17.0 ft, discharge, 135,000 ft3/s, from rating extended above 46,000 ft3/s. Flood of Mar. 1, 1902 reached a stage of 14.8 ft, discharge, 98,000 ft3/s.
FLOOD STAGE.--NOAA, National Weather Service river forecast station flood stage provided to USGS April 1999 is 11 feet.
COOPERATION.--Funding for the operation of this station is provided by the City of Philadelphia, the U.S. Army Corps of Engineers, and the U.S. Geological Survey.
