Monitoring location 01473000 is associated with a Stream in Montgomery County, Pennsylvania. Current conditions of Discharge, Gage height, Precipitation, and more are available. Water data back to 1914 are available online.
June 1914, to Sept. 6, 1921, non-recording gage at site 1,650 ft downstream at datum 3.29 ft lower. Sept. 7, 1921, to Sept. 13, 1927, non-recording gage at present site and datum. Regulations from Green Lane Reservoir since December 1956 and from the Bradshaw Distributary since October 1994. Unknown amounts from pumpage to the Limerick power plant on the Schuylkill River. The 15-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.
