Water-Year
Summary
instructions
and
information
- Water-Year Summary reports summarize a year of hydrologic data in a printer-friendly format.
- For water years 2014 onward, choose a water year and parameter and an on-demand Water-Year Summary report will be generated.
- For water years 2006 through 2013, choose a water year and an Annual Water Data Report will be provided.
- For water years 2005 and earlier, Annual Water Data Reports may be available in digital format.
- Not all sites have reports available for every water year.

WATER-QUALITY RECORDS
PERIOD OF RECORD - November 2010 to current year.
PERIOD OF DAILY RECORD - 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.
SUSPENDED-SEDIMENT CONCENTRATION: November 2010 to September 2011, October 2012 to current year.
SUSPENDED-SEDIMENT DISCHARGE: October 2012 to current year.
COOPERATION - In cooperation with the New York City Department of Environmental Protection.
INSTRUMENTATION - An optical turbidity sensor provides readings at 15-minute intervals since November 2010.
REMARKS - 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.
EXTREMES FOR PERIOD OF DAILY RECORD - 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.
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.
