       NYS Department of Environmental Conservation


    LOCATION.--Lat 44°27'05", long 73°38'33" referenced to North American Datum of 1983, Clinton County, NY, Hydrologic Unit 02010004, on left bank 1.8 mi downstream from confluence of East and West Branches, and 1.8 mi east of Au Sable Forks.
    DRAINAGE AREA.--446 mi2.
    PERIOD OF RECORD.--August 1910 to September 1968, March 1990 to current year. Prior to October 1924, published as "at Au Sable Forks". Monthly discharge only for winter periods during 1911 and 1913 water years, published in WSP 1307.
    REVISED RECORDS.--WSP 1307: 1911-19 (M), 1922-24 (M).
    GAGE.--Water-stage recorder and crest-stage gage. Datum of gage is 505.65 ft above NGVD of 1929. Prior to Oct. l, 1924, nonrecording gage at site 1.5 mi upstream at different datum.
    REMARKS.--Records good except those for estimated daily discharges, which are poor. Occasional regulation by Fern Lake and Taylor Pond in Black Brook basin and Upper and Lower Ausable Lakes. Satellite and telephone gage-height telemeter at station.
    EXTREMES FOR PERIOD OF RECORD.--Maximum discharge, 46,500 ft3/s, Aug. 28, 2011, gage height, 15.54 ft, from rating curve extended above 16,000 ft3/s on basis of runoff comparison of peak flows from contracted-opening measurements at gage heights 13.83 ft and 15.54 ft at site 3.9 mi downstream; minimum discharge, practically no flow July 21, 1912, result of unusual regulation.
    EXTREMES OUTSIDE PERIOD OF RECORD.--Flood of Feb. 23, 1990 (ice jam), reached a stage of 14.5 ft, from floodmark 200 ft upstream from gage.
