USGS Water-Year Summary 2021
01311143 HOG ISLAND CHANNEL AT ISLAND PARK, NY
LOCATION - Lat 40°36'31.8", long 73°39'22.0" 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. Datum of gage is NGVD of 1929.
REMARKS - Elevation WY 2014: Records good, except those for Oct. 26 to Dec. 3, June 11 to Aug. 21, Sept. 25-30, which are fair, Dec. 4 to Jan. 1, Aug. 22 to Sept. 24, which are poor, and Jan. 2 to May 28, which were deleted. Periods of missing record were estimated with MISTE using a linear regression with 01311145 and 01310740. Satellite elevation telemeter at station.
EXTREMES OUTSIDE PERIOD OF RECORD - Storm tide of Dec. 11, 1992, reached an elevation of 7.3 ft, from high-water mark at site 1.1 mi south-southwest.
EXTREMES FOR PERIOD OF RECORD - Maximum elevation, 10.89 ft, Oct. 29, 2012; minimum elevation, -4.22 ft, Feb. 20, 2015.
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 Sampling depth records for October 2010 to current year are unpublished and available in files of the Geological Survey.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 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, chlorophyll, nitrate, and sampling depth parameters at station. Interruptions of record were due to the malfunction of water-quality monitors or sensors. WATER TEMPERATURE WY 2016: Records excellent. SALINITY WY 2016: Records excellent, except those for Oct. 1-13, May 12 to June 7, June 26 to July 23, Sept. 5-7, 12-26, which are good, Oct. 14-23, July 24-30, Sept. 27-30, which are fair, and Oct. 24 to Nov. 17, July 31 to Aug. 10, which are poor.
