Water Data for the Nation inventory

From September 1961 to March 1969, gage at present site, at datum 140.70 ft above National Geodetic Vertical Datum of 1929. Calibration of water-quality instrumentation is conducted exclusively by Philadelphia Water Department personnel with USGS oversight. Erroneous or missing data, resulting from instrument malfunction, are not the responsibility of USGS. Regulation is unknown; possible minor pumping and withdrawals upstream, probably from treatment facilities or water intakes. The continuous water-quality monitor operated by the Philadelphia Water Department is located at Lat 40`07'26.1", Long 75`13`07.1", approximately 350 feet upstream of gage.
