DRAINAGE AREA.--25 mi².
PERIOD OF RECORD.--Miscellaneous measurements--1954, 2010. October 2010 to current year.
GAGE.--Water-stage recorder. Elevation of gage is 700 ft above NAVD of 1988, from topographic map.
REMARKS.--Water Years 2014-23: Records poor.
EXTREMES FOR PERIOD OF RECORD.--Maximum discharge, 12,600 ft³/s, Aug. 28, 2011, gage height, 15.15 ft, but may have been higher during period of missing data on that day; minimum discharge undetermined.
PERIOD OF RECORD1.--November 2010 to current year.
PERIOD OF DAILY RECORD1.--TURBIDITY: DTS12 - November 2010 to September 2011, October 2012 to current year. Analite - August 2022 to current year.
SUSPENDED-SEDIMENT CONCENTRATION: November 2010 to September 2011, October 2012 to current year.
SUSPENDED-SEDIMENT DISCHARGE: October 2012 to current year.
INSTRUMENTATION1.--An optical turbidity sensor provides readings at 15-minute intervals since November 2010.
REMARKS1.--Turbidity data are collected every 15 minutes using an in-situ turbidity probe located in a 2-inch diameter galvanized steel pipe extending 10 ft from the left bank. Daily suspended-sediment load and concentration are derived from a regression equation relating turbidity to suspended-sediment concentration.
COOPERATION1.--In cooperation with the New York City Department of Environmental Protection.
EXTREMES FOR PERIOD OF DAILY RECORD1.--TURBIDITY: DTS12 - Maximum, 1,980 FNU, Feb. 25, 2016; minimum, <0.2 FNU, on many days. Analite - Maximum, 1,380 FNU, Aug. 30, 2023; minimum, <0.2FNU, on several days. [<, actual value is known to be less than the value shown]
SUSPENDED-SEDIMENT CONCENTRATION: Maximum daily mean, 1,630 mg/L, Aug. 28, 2011; minimum daily mean, <1 mg/L, on many days in 2011, 2013-14.
SUSPENDED-SEDIMENT DISCHARGE: Maximum daily, 1,270 tons, Oct. 19, 2012; minimum daily, <0.01 tons, on many days in 2013-14.
