    This station is operated in cooperation with:
       NYS Department of Environmental Conservation
       U.S. Geological Survey


    LOCATION.--Lat 42°05'11", long 76°48'04" referenced to North American Datum of 1983, Chemung County, NY, Hydrologic Unit 02050105, on right bank 350 ft upstream from bridge on Pennsylvania Avenue at the north end of George Place at Elmira and 1.0 mi downstream from Hoffman Brook.
    DRAINAGE AREA.--2,162 mi2.
    PERIOD OF RECORD.--Annual maximum only--1988-2009, October 2009 to current year.
    GAGE.--Water-stage recorder and crest-stage gage. Datum of gage is 833.65 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. Diversion upstream from City of Corning and Town of Horseheads for municipal supply, which may include water from several municipal and industrial wells upstream from gage. Telephone and satellite gage-height and precipitation telemeters at station.
    EXTREMES FOR PERIOD OF RECORD.--Maximum discharge, about 71,000 ft3/s, Jan. 20, 1996, gage height, 18.51 ft, from floodmark (ice jam); minimum discharge, 142 ft3/s, Aug. 21, 22, Sept. 25, 26, 27, 2010, gage height 0.87 ft.
