Click to hide 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.

PERIOD OF RECORD - July 2012 to current year.
GAGE - Water-stage recorder. Datum of gage is NGVD of 1929.
REMARKS - Satellite telemeter for elevation at station. Gaps in record caused by equipment malfunctions are filled with estimated data from nearby gage 01304562 Peconic River at Hwy 105 Riverhead, NY.
EXTREMES OUTSIDE PERIOD OF RECORD - Storm tide of Dec. 11, 1992, reached an elevation of 4.8 ft, from high-water mark at site 0.6 mi northwest.
EXTREMES FOR PERIOD OF RECORD - Maximum elevation, 7.37 ft, Oct. 29, 2012; minimum elevation, -3.66 ft, Jan. 5, 2018.
PERIOD OF RECORD - August 2012 to current year.
PERIOD OF DAILY RECORD - WATER TEMPERATURE: August 2012 to current year. SALINITY: August 2012 to current year. DISSOLVED OXYGEN: August 2012 to current year. pH: August 2012 to current year. TURBIDITY: August 2012 to current year. NITRATE: August 2012 to current year.
INSTRUMENTATION - Water-quality monitor provides 6-minute-interval readings collected from 1.6 ft above bottom. Nitrate analyzer provides 30-minute-interval readings collected from 1.6 ft above bottom. Salinity record computed from specific-conductance readings.
REMARKS - Satellite telemeter for water temperature, specific conductance, dissolved oxygen, pH, turbidity, and nitrate parameters at station.
