Water Data for the Nation inventory

Monitoring location 01474500 is associated with a Stream in Philadelphia County, Pennsylvania. Current conditions of Barometric pressure (BP), Discharge, Dissolved oxygen, and more are available. Water data back to 1869 are available online.

Calibration of specific conductance, dissolved oxygen, and pH 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. The 30-minute precipitation data for this station are temporary and will only be displayed for 120 days. Time series of 1-hour or cumulative daily values will NOT be available for retrieval following the 120-day display period. Although the instrumentation is calibrated at least once a year, the temporary classification means that documented routine inspections and other quality assurance measures are not performed that would make the data acceptable for archival, retrieval, or future use in general scientific or interpretive studies.
