    DRAINAGE AREA.--5,982 mi2.
    PERIOD OF RECORD.--October 1914 to current year. Monthly discharge only for some periods, published in WSP 1305. Gage-height records collected at same site since April 1905 are contained in reports of U.S. Weather Bureau.
    GAGE.--Water-stage recorder. Datum of gage is 955.84 ft above National Geodetic Vertical Datum of 1929. Prior to Sept. 16, 1932, nonrecording gage, and Sept. 16-30, 1932, water-stage recorder, at present site at datum 2.00 ft higher.
    REMARKS.--Flow regulated by Allegheny Reservoir 74 mi upstream since 1965, by Chautauqua Lake since 1941, by Tionesta Lake since 1940, by Union City Reservoir since 1971, and by Woodcock Creek Lake since January 1974. U.S. Army Corps of Engineers satellite telemeter at station.
    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.

    EXTREMES OUTSIDE PERIOD OF RECORD.--Flood of Mar. 17, 1865 reached a stage of 25.0 ft, and that of Mar. 26, 1913 a stage of 24.6 ft, from graph based on gage readings, discharge, 196,000 ft3/s and 191,000 ft3/s, respectively, from rating curve extended above 120,000 ft3/s. Maximum discharge since at least 1864 is that of Mar. 17, 1865.
    GAGE HEIGHTS OF IMPORTANCE.-
    Supplied by NWS: Action stage-13 ft; Flood stage-17 ft; Moderate flood stage-19 ft; Major flood stage-21 ft.
