   New York City Department of Environmental Protection


> Site Information
LOCATION.--Lat 41°52'45.6", long 74°08'43.3" referenced to North American Datum of 1983, Ulster County, NY, Hydrologic Unit 02020006, on right bank at downstream side of abandoned bridge abutment upstream from Hurley Mountain Road, 5.6 mi downstream from Ashokan Reservoir, 1.2 mi southwest of Lomontville.
DRAINAGE AREA.--279 mi².
PERIOD OF RECORD.--November 2013 to current year.
GAGE.--Water-stage recorder and crest-stage gage. Datum of gage is 191.93 ft above NGVD of 1929 and 191.20 ft above NAVD of 1988 (VERTCON).
REMARKS.--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. Diversions for water supply of City of New York made from Ashokan Reservoir (station 01363400).
Water Years 2014-19: Records fair except those for estimated daily discharges, which are poor.
EXTREMES FOR PERIOD OF RECORD.--Maximum discharge, 4,300 ft³/s, Sept. 30, 2015, gage height, 7.91 ft; minimum discharge, 2.4 ft³/s, Oct. 3, 4, 2014, gage height, 2.01 ft.
EXTREMES OUTSIDE PERIOD OF RECORD.--Flood of Apr. 3, 2005, reached a stage of 16.68 ft, from floodmark on left bank 30 ft downstream from gage.
PERIOD OF DAILY RECORD1.--SUSPENDED-SEDIMENT DISCHARGE: November 2013 to current year.
REMARKS1.--Turbidity data are collected every 15 minutes using an in-situ turbidity probe located in a 2 inch pipe about 100 ft across stream on left bank in a separate gage shelter. Daily suspended-sediment load and concentration are derived from a regression equation relating turbidity to suspended-sediment concentration.
EXTREMES FOR PERIOD OF DAILY RECORD1.--SUSPENDED-SEDIMENT CONCENTRATION: Maximum daily mean, about 210 mg/L, Mar. 30, 2014; minimum daily mean, <1 mg/L, on many days during 2014-15 water years.
SUSPENDED-SEDIMENT DISCHARGE: Maximum daily, 770 tons, Sept. 30, 2015; minimum daily, about 0.01 ton, Oct. 3, 2014, May 30, 2015.
