USGS Water-Year Summary 2024

01302845 FROST CREEK AT SHEEP LANE BRIDGE AT LATTINGTOWN, NY

LOCATION - Lat 40°54'18.4", long 73°35'35.5" referenced to North American Datum of 1983, Nassau County, NY, Hydrologic Unit 02030201, at Sheep Lane bridge, in Lattingtown.

REVISIONS HISTORY - Estuary elevation record for the period June 22 through Sept. 21, 2010 was revised on May 8, 2025 based on equipment malfunction. Estuary elevation record from Sept. 5, 2018 to Aug. 16, 2023 was revised on Mar. 21, 2025 based on computational error.

SURFACE-WATER RECORDS

PERIOD OF RECORD - December 2007 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 1.08 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. Gaps in record caused by equipment malfunctions are filled with estimated data from nearby gage 01302600 West Pond at Glen Cove NY and 01304057 Flax Pond at Old Field NY.

EXTREMES OUTSIDE PERIOD OF RECORD - Storm tide of Dec. 11, 1992, reached an elevation of 11.9 ft above NGVD of 1929 (10.82 ft above NAVD of 1988), from high-water mark at site 0.78 mi north-northeast.

EXTREMES FOR PERIOD OF RECORD - Maximum elevation, 11.12 ft above NGVD of 1929 (10.04 ft above NAVD of 1988), Oct. 29, 2012; minimum elevation, -0.58 ft above NGVD of 1929 (-1.66 ft above NAVD of 1988), Apr. 17, 2014.

WATER-QUALITY RECORDS

PERIOD OF RECORD - December 2007 to current year. Sampling depth records for December 2007 to current year are unpublished and available in files of the Geological Survey.

PERIOD OF DAILY RECORD - WATER TEMPERATURE: December 2007 to current year. SALINITY: December 2007 to current year.

INSTRUMENTATION - Water-quality monitor provides 6-minute-interval readings collected from 0.5 ft above bottom. Salinity record computed from specific-conductance readings.

REMARKS - Satellite telemeter for water temperature, specific conductance, and sampling depth parameters at station. Station discontinued from Oct. 1, 2011, to Sept. 30, 2012.

EXTREMES FOR PERIOD OF RECORD -

WATER TEMPERATURE: Maximum, 34.4 °C, July 18, 2013; minimum, -1.7 °C, on many days.

SALINITY: Maximum, 32.6 psu, Jan. 2, 2018; minimum, 4.1 psu, July 1, 2015.
