Schuylkill River at Norristown, PA - 01473500

October 1927 to May 1933, at site 0.6 miles downstream, at different datum. October 1983 to September 1993, annual maximums from crest-stage gage located 0.7 miles downstream, at different datum. 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. Reported drainage area includes that of Stony Creek, which enters the gage pool 1200 ft downstream of gage.
