USGS 01310740 REYNOLDS CHANNEL AT POINT LOOKOUT NY

PROVISIONAL DATA SUBJECT TO REVISION

Click to hidestation-specific text
The 6-minute meteorological data for this station are temporary and will only be displayed for 120 days. Although the instrumentation is calibrated at least once/year, the temporary classification means that documented routine inspections and other quality assurance measures are not performed that would make the data acceptable for archival, retrieval, or future use in general scientific or interpretive studies.

> Site Information
    LOCATION.--Lat 40°35'36", long 73°35'03" referenced to North American Datum of 1927, Nassau County, NY, Hydrologic Unit 02030202, at Town of Hempstead East Marina, 750 ft east of Loop Parkway Bridge, in Point Lookout. Water-quality monitor at site 100 ft north.
    PERIOD OF RECORD.--December 1997 to current year. January 1974 to June 1994, in files of Town of Hempstead Department of Conservation & Waterways. Precipitation, wind speed and direction, air temperature, relative humidity, and barometric pressure records for March 1998 to current year, and solar radiation records for August 2004 to current year, are unpublished and available in files of the Geological Survey.
    GAGE.--Water-stage recorder. Datum of gage is NGVD of 1929. January 1974 to June 1994, water-stage recorder at site 150 ft northeast.
    REMARKS.--ELEVATION WY 2014: Records rated good, except those for Oct. 1-22, Oct. 28 to Jan. 19, Jan. 29, June 21 to July 6, Aug. 12-18, 26-31, Sept. 11-20, which are fair, Oct. 23-27, Jan. 20-28, Jan. 30 to June 20, July 31 to Aug. 11, Sept. 1-10, 29-30, which are poor and July 7-30 which were deleted. Periods of missing record were estimated with MISTE using a linear regression with 01310521 and 01311143. Satellite and telephone elevation, precipitation, and wind speed and direction telemeters at station. Telephone telemeter for air temperature, relative humidity, barometric pressure, and solar radiation parameters at station.
    EXTREMES FOR PERIOD OF RECORD.--Maximum elevation, 9.90 ft, Oct. 29, 2012; minimum elevation, -4.28 ft, Mar. 9, 2005.
    EXTREMES OUTSIDE PERIOD OF RECORD.--Storm tide of Sept. 27, 1985, reached an elevation of 7.3 ft, from information provided by Town of Hempstead Department of Conservation & Waterways.
