    Click to hidestation-specific text

    This station is operated in cooperation with:
       U.S. Army Corps of Engineers - Baltimore District
       U.S. Geological Survey


    LOCATION.--Lat 42°08'47", long 77°03'27" referenced to North American Datum of 1983, Steuben County, NY, Hydrologic Unit 02050105, on right bank adjacent to Corning Glass Works power plant, 500 ft downstream from Bridge Street, 1.7 mi downstream from Cohocton River, at Corning.
    DRAINAGE AREA.--2,006 mi2.
    PERIOD OF RECORD.--Occasional discharge measurements, water years 1941, 1968-69. October 1974 to current year.
    REVISED RECORDS.--WDR NY-78-1: 1976, 1977 (m). WDR NY-83-3: 1982 (M).
    GAGE.--Water-stage recorder. Datum of gage is 900.00 ft above NGVD of 1929.
    REMARKS.--Records good except those for estimated daily discharges, which are fair. High flows significantly regulated by upstream reservoirs. During each year a large part of flow from 45.5 mi2 of drainage area is diverted upstream from Lake Lamoka on Mud Creek, an upstream tributary, into Keuka Lake (Oswego River basin) for power development. Telephone and satellite gage-height telemeters at station.
    EXTREMES FOR PERIOD OF RECORD.--Maximum discharge, since construction of Tioga, Hammond and Cowanesque Lakes in 1979, about 61,000 ft3/s, Jan. 19, 1996; minimum discharge, 95 ft3/s, Sept. 9, 10, 23, 24, 1991, gage height, 14.30 ft.
    EXTREMES OUTSIDE PERIOD OF RECORD.--Flood of June 23, 1972, reached a stage of 40.71 ft, from floodmark, discharge, 228,000 ft3/s, from peak flows determined at upstream and downstream stations adjusted for drainage area and channel storage.
    EXTREMES FOR PERIOD PRIOR TO REGULATION.--Maximum discharge, prior to construction of Tioga, Hammond and Cowanesque Lakes in 1979, 127,000 ft3/s, Sept. 26, 1975, gage height, 32.46 ft; minimum discharge, 210 ft3/s, Aug. 29, 1978.
