Water-quality sampling site at elevation station.
DRAINAGE AREA.--8,288 mi².
PERIOD OF RECORD.--October 1972 to September 1976 and April 1981 to September 1999 (monthly maximum, minimum, and mean elevations), October 1999 to September 2002 (daily high, low, and mean elevations), October 2002 to current year.
REVISIONS HISTORY.--WDR NY-90-1: Drainage area.
GAGE.--Water-stage recorder. Datum of gage is NGVD of 1929. To convert elevations to NAVD of 1988, subtract 0.84 ft. Prior to Feb. 27, 2002, at site 1,000 ft upstream at datum 10.00 ft lower.
REMARKS.--Blanks in tables are the result of only one high or low tide during a day or interruption of record.
EXTREMES FOR PERIOD OF RECORD.--Maximum elevation, 15.49 ft, present datum, Jan. 20, 1996; minimum elevation, -4.50 ft, present datum, Mar. 8, 1986.
EXTREMES OUTSIDE PERIOD OF RECORD.--Flood of Feb. 9, 1857, reached an elevation of 21.71 ft, present datum, result of ice jam, from information provided by U.S. Army Corps of Engineers. Flood of Mar. 28, 1913, reached an elevation of 21.45 ft, present datum, discharge, 240,000 ft³/s (estimated, tide affected) from information provided by Board of Hudson River-Black River Regulating District.
PERIOD OF DAILY RECORD1.--WATER TEMPERATURE: February 2002 to current year.
INSTRUMENTATION1.--Water-temperature satellite and telephone telemeter provides 15-minute-interval readings.
REMARKS1.--Temperature readings prior to Oct. 1, 2007, rounded to nearest 0.5 °C.
EXTREMES FOR PERIOD OF DAILY RECORD1.--WATER TEMPERATURE: Prior to Oct. 1, 2007--Maximum, 28.5 °C, Aug. 18, 19, 21, 2002, several days during 2005 summer period, Aug. 3, 4, 5, 2007; minimum (water years 2003-07), 0.0 °C on many days during winter period. WATER TEMPERATURE: After Oct. 1, 2007--Maximum, 29.5 °C, July 27, 2020; minimum, -0.3 °C, Mar. 3, 2009.

NAVD 1988 Datum Conversion Information


Elevation observations and tidal predictions for this station are reported to NGVD 1929. To convert data to NAVD 1988 subtract 0.76 ft. To convert data to MHHW datum subtract 4.54 ft. To convert data to MLLW datum add 1.04 ft. These corrections vary from site to site.

NGVD 1929 is the National Geodetic Vertical Datum of 1929, formerly called "mean sea level" or "Sea Level Datum of 1929." NGVD 1929 was a general adjustment of the first-order level nets fit to mean sea level at 26 tide gages in the US and Canada.
NAVD 1988 is the North American Vertical Datum of 1988, which is a geodetic datum derived from a general adjustment of the first-order level nets fit to 1 tide gage in eastern Canada.
MHHW is mean higher high water, which is a site-specific datum determined by averaging the highest of the 2 high tides that occur each day over a 19-year tidal epoch. For tide gages with less than 19 years of record, this datum is estimated by correlation with long-term tide gages.
MLLW is mean lower low water, which is a site-specific datum determined by averaging the lowest of the 2 low tides that occur each day over a 19-year tidal epoch. For tide gages with less than 19 years of record, this datum is estimated by correlation with long-term tide gages.
