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 2024
01304650 SHELTER ISLAND SOUND AT SHELTER ISLAND NY
LOCATION - Lat 41°02'39.5", long 72°19'01.1" referenced to North American Datum of 1983, Suffolk County, NY, Hydrologic Unit 02030202, at South Ferry Inc. ferry service property.
SURFACE-WATER RECORDS
PERIOD OF RECORD - November 2020 to current year.
GAGE - Water-stage recorder. Estuary elevation record is available in ft above NGVD of 1929 and ft above NAVD of 1988.
REMARKS - Satellite and modem telemeter for elevation at station. Elevations are not 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. Gaps in record caused by equipment malfunctions are estimated by comparison with estuary elevation data from USGS station 01304200 Orient Harbor at Orient, NY.
EXTREMES FOR PERIOD OF RECORD - Maximum elevation, 5.78 ft above NGVD of 1929 (4.84 ft above NAVD of 1988), Apr. 4, 2024; minimum elevation, -2.46 ft above NGVD of 1929 (-3.40 ft above NAVD of 1988), Mar. 2, 2021.
WATER-QUALITY RECORDS
PERIOD OF DAILY RECORD - WATER TEMPERATURE: September 2022 to current. SALINITY: September 2022 to current. pH: September 2022 to current. DISSOLVED OXYGEN: September 2022 to current. TURBIDITY: September 2022 to current. TAL-PE: September 2022 to current.
INSTRUMENTATION - Water-quality monitor provides 6-minute-interval readings collected from 1.5 ft above the bottom. Multi-parameter water-quality sonde measures temperature, specific conductance, pH, dissolved oxygen, turbidity, and TAL-PE.
EXTREMES FOR PERIOD OF DAILY RECORD - WATER TEMPERATURE: Maximum, 27.7 'C, July 29, 2023; minimum, -1.2 'C, Jan. 28, 2025.
SALINITY: Maximum, 32.0 psu, Dec. 27, 2022; minimum, 25.6 psu, May 16, 2024.
pH: Maximum, 8.3 standard units, several days in January 2024; minimum, 7.3 standard units, Sept. 11, 2023.
DISSOLVED OXYGEN: Maximum, 13.2 mg/L, Jan. 24, 25, 26, 2025; minimum, 2.3 mg/L, July 13, 2023.
TURBIDITY: Maximum, 67.6 FNU, Dec. 24, 2022; minimum, <0.3 FNU, on many days. [<, actual value is known to be less than the value shown]
CHLOROPHYLL FLUORESCENCE: Maximum, 121.41 ug/L, 30.23 RFU, Apr. 5, 2024; minimum, 0.00 ug/L, 0.00 RFU, on several days.
PHYCOERETHRINE FLUORESCENCE: Maximum, >280 ug/L, >100 RFU, Feb. 16, 2025; minimum, 0.00 ug/L, 0.00 RFU, on several days.
