Water Data for the Nation inventory

Monitoring location 01474000 is associated with a Stream in Philadelphia County, Pennsylvania. Current conditions of Discharge, Dissolved oxygen, Gage height, and more are available. Water data back to 1959 are available online.

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. Possible pumping from quarry 6 miles upstream. Possible diversions for irrigation. The continuous water-quality monitor operated by the Philadelphia Water Department is located at Lat 40`01'21.5", Long 75`11`53.8", approximately 3,800 feet upstream of gage.
