    This station is operated in cooperation with:
       NYS Department of Environmental Conservation


    LOCATION.--Lat 45°00'00", long 73°30'03" referenced to North American Datum of 1983, Clinton County, NY, Hydrologic Unit 02010006, on left bank 500 ft upstream from bridge on Creek Road at Perry Mills, and 7.5 mi upstream from Corbeau Creek.
    DRAINAGE AREA.--243 mi2.
    PERIOD OF RECORD.--September 1928 to September 1968, annual maximum only--1985, 1987-89, March 1990 to current year.
    GAGE.--Water-stage recorder and crest-stage gage. Datum of gage is 164.93 ft above NGVD of 1929.
    REMARKS.--Records good except those for estimated daily discharges, which are poor. At flows greater than about 2,000 ft3/s, significant undetermined amounts of flow bypass the gage. Records prior to October 1968 affected by diurnal fluctuation at low and medium flow by sawmill immediately upstream. Occasional regulation by Chazy Lake (usable capacity, about 765 mil ft3) from which the Clinton Correctional Facility at Dannemora (Saranac River basin) obtains its water supply (about 1 ft3/s). Satellite and telephone gage-height telemeter at station.
    EXTREMES FOR PERIOD OF RECORD.--Maximum discharge, 9,700 ft3/s, Nov. 9, 1996, gage height, 12.24 ft; maximum gage height, 12.91 ft, from floodmark in gage house, Feb. 28, 2000 (ice jam); minimum discharge, about 0.8 ft3/s, Sept. 18, 1932; minimum gage height, 1.22 ft, Sept. 6, 14, 1999.
