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.

USGS Water-Year Summary 2025
01311143 HOG ISLAND CHANNEL AT ISLAND PARK, NY
LOCATION - Lat 40°36'31.15", long 73°39'22.22" referenced to North American Datum of 1983, Nassau County, NY, Hydrologic Unit 02030202, at Village of Island Park Masone Beach Pier, in Island Park.
SURFACE-WATER RECORDS
PERIOD OF RECORD - October 2010 to current year.
GAGE - Water-stage recorder. Estuary elevation record is available in ft above NGVD of 1929 and ft above NAVD of 1988. To convert NGVD of 1929 elevation to NAVD of 1988 elevation, subtract 1.12 ft.
REMARKS - Satellite telemeter for elevation at station. Elevations are corrected for changes in water density. Blanks in tables are the result of only one high or low tide during a day or interruption of record.
EXTREMES OUTSIDE PERIOD OF RECORD - Storm tide of Dec. 11, 1992, reached an elevation of 7.3 ft above NGVD of 1929 (6.18 ft above NAVD of 1988), from high-water mark at site 1.1 mi south-southwest.
EXTREMES FOR PERIOD OF RECORD - Maximum elevation, 10.89 ft above NGVD of 1929 (9.77 ft above NAVD of 1988), Oct. 29, 2012; minimum elevation, -5.95 ft above NGVD of 1929 (-7.07 ft above NAVD of 1988), Jan. 22, 2019.
WATER-QUALITY RECORDS
PERIOD OF RECORD - October 2010 to current year. Sampling depth records for October 2010 to current year are unpublished and available in files of the Geological Survey.
PERIOD OF DAILY RECORD - WATER TEMPERATURE: October 2010 to current year. SALINITY: October 2010 to current year. DISSOLVED OXYGEN: October 2010 to current year. pH: October 2012 to current year. TURBIDITY: October 2010 to current year. CHLOROPHYLL: October 2010 to current year. NITRATE: March 2011 to April 2022.
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, chlorophyll, nitrate, and sampling depth parameters at station. WATER TEMPERATURE WY 2016: Records excellent.
