Water Data for the Nation inventory

Monitoring location 01473900 is associated with a Stream in Montgomery County, Pennsylvania. Current conditions of Discharge, Dissolved oxygen, Gage height, and more are available. Water data back to 1961 are available online.

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.
