       New York City Department of Environmental Protection
       NYS Department of Environmental Conservation
       Ulster County


    LOCATION.--Lat 42°02'16", long 73°58'19" referenced to North American Datum of 1983, Ulster County, NY, Hydrologic Unit 02020006, on left bank at downstream side of bridge on Glasco Turnpike, 0.8 mi east of Mount Marion, 1.6 mi downstream from Plattekill Creek, and 4.5 mi upstream from mouth.
    DRAINAGE AREA.--419 mi2.
    PERIOD OF RECORD.--Occasional miscellaneous discharge measurements, 1902, 1951, 1956, 1966, 1967, 1969. April 1907 to December 1913 (furnished by Board of Water Supply, City of New York), January 1914 to March 1918 (monthly discharges only, furnished by Board of Water Supply, City of New York, published in WSP 1302), March 1970 to current year.
    GAGE.--Water-stage recorder and crest-stage gage. Datum of gage is 40.15 ft above NGVD of 1929. Prior to Aug. 12, 1970, nonrecording gage at same site (at different datum April 1907 to March 1918).
    REMARKS.--Records good except those for estimated daily discharges, which are fair. Flow from 256 mi2 of drainage area regulated by Ashokan Reservoir since Sept. 9, 1913. Water diverted from Schoharie Creek through Shandaken Tunnel (station 01362230) since Feb. 3, 1924, enters Esopus Creek about 12.2 mi upstream from Ashokan Reservoir. Diversion from Plattekill Creek for water supply of village of Saugerties. Slight diversion at headwaters into Cooper Lake for water supply of Kingston. Diversions upstream during summer months for irrigation purposes. Diversions for water supply of city of New York made from Ashokan Reservoir (station 01363400). Discharge records for this station now represent the natural flow from 112 mi2, together with conservation releases and spillage during high stages from the upstream reservoirs. Satellite and telephone gage-height telemeter at station.
    EXTREMES FOR PERIOD OF RECORD.--Maximum discharge observed, 28,000 ft3/s, Apr. 26, 1910, gage height, 25.10 ft, datum then in use; maximum discharge since March 1970, 30,500 ft3/s, Apr. 3, 2005, gage height, 26.46 ft, outside gage height was 26.19 ft, from crest-stage gage; minimum discharge, 5.3 ft3/s, Aug. 10, 1999, gage height, 11.51 ft.
