    Click to hidestation-specific text

    This station is operated in cooperation with:
       National Weather Service
       U.S. Geological Survey


    LOCATION.--Lat 42°00'08", long 76°38'05" referenced to North American Datum of 1983, Chemung County, NY, Hydrologic Unit 02050105, on right bank 100 ft upstream from bridge on State Highway 427, 0.7 mi southwest of Chemung, and 10.0 mi upstream from mouth.
    DRAINAGE AREA.--2,506 mi2.
    PERIOD OF RECORD.--September 1903 to current year (gage heights only for some winter periods).
    REVISED RECORDS.--WSP 891: 1935-39. WSP 1432: 1904, 1907, 1915. WSP 2103: Drainage area. WDR NY-74-1: 1973.
    GAGE.--Water-stage recorder. Datum of gage is 778.63 ft above NGVD of 1929 (levels by Corps of Engineers). Prior to Jan. 10, 1930, nonrecording gage on highway bridge 60 ft upstream at same datum.
    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, 77,800 ft3/s, Jan. 20, 1996, gage height 19.71 ft; minimum discharge, 104 ft3/s, Sept. 3, 1991, gage height, 2.82 ft.
    EXTREMES FOR PERIOD PRIOR TO REGULATION.--Maximum discharge, prior to construction of Tioga, Hammond and Cowanesque Lakes in 1979, 189,000 ft3/s, June 23, 1972, gage height, 31.62 ft, from floodmark, from rating curve extended above 65,000 ft3/s on basis of slope-area and velocity-area studies at gage height 19.57 ft, and slope-area and contracted-opening measurements at gage heights 23.97 ft and 31.62 ft, respectively; minimum discharge, 49 ft3/s, Aug. 14, 1911, gage height, 1.47 ft.
