    This station is operated in cooperation with:
       NYS Department of Environmental Conservation


    LOCATION.--Lat 41°23'10", long 73°57'20" referenced to North American Datum of 1927, Orange County, NY, Hydrologic Unit 02020008, on right bank at South Dock at West Point. Water-quality sampling site at elevation station.
    DRAINAGE AREA.--12,596 mi2.
    PERIOD OF RECORD.--October 1991 to February 2012, June to September 2013. Records for June 1989 to September 1991 are unpublished and available in files of the Geological Survey.
    GAGE.--Water-stage recorder. Datum of gage is NGVD of 1929.
    REMARKS.--Prior to October 2002 published as maximum, minimum, and mean elevation. 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. Satellite and telephone elevation and water-quality telemeter at station.
    EXTREMES FOR PERIOD OF RECORD.--Maximum elevation, 7.65 ft, Aug. 28, 2011; minimum elevation, -4.26 ft, Mar. 14, 1993.
    EXTREMES OUTSIDE PERIOD OF RECORD.--Flood of Oct. 29, 2012, reached an elevation of 9.60 ft, from floodmark.
    PERIOD OF DAILY RECORD1.--SPECIFIC CONDUCTANCE: October 1991 to February 2012, June to September 2013. Records for February 1990 to September 1991 are unpublished and available in files of the Geological Survey.
    WATER TEMPERATURE: October 1991 to February 2012, June to September 2013. Records for February 1990 to September 1991 are unpublished and available in files of the Geological Survey.
    pH: June to September 2013.
    DISSOLVED OXYGEN: June to September 2013.
    TURBIDITY: June to September 2013.
    INSTRUMENTATION1.--A continuous water-quality monitor with water temperature, specific conductance, pH, dissolved oxygen and turbidity provides 15-minute-interval readings.
    EXTREMES FOR PERIOD OF DAILY RECORD1.--SPECIFIC CONDUCTANCE: Maximum, 12,600 uS/cm, Sept. 23, 1995; minimum, 102 uS/cm, May 30, 1996.
    WATER TEMPERATURE: Prior to Oct. 1, 2007--Maximum, 29.0 °C, Aug. 12, 13, 14, 2005; minimum, 0.0 °C on many days during winter periods, except 1998, 2002.
    WATER TEMPERATURE: After Oct. 1, 2007--Maximum, 28.2 °C, July 24, 27, 2010; minimum, -0.2 °C on many days during 2009 winter period.
