Juniata River at Huntingdon, PA - 01559000

Flow slightly regulated September 1941 to June 1972. Since December 15, 1985 low flows slightly regulated by Warrior Ridge Hydroelectric Plant, 4 mi upstream (reservoir capacity 400 acre-ft). The 1-hour 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.
