ALL DATA ARE EASTERN STANDARD TIME

USGS 01359139 HUDSON RIVER AT ALBANY NY

PROVISIONAL DATA SUBJECT TO REVISION

Click to hidestation-specific text

 

LOCATION.--Lat 42°38'46", long 73°44'51" referenced to North American Datum of 1983, Albany County, NY, Hydrologic Unit 02020006, on right bank 0.1 mi upstream from bridge on U.S. Highways 9 and 20 in Albany, and 0.7 mi downstream from railroad bridge. Water-quality sampling site at elevation station.
DRAINAGE AREA.--8,288 mi2.
PERIOD OF RECORD.--October 1972 to September 1976, April 1981 to current year.
REVISED RECORDS.--WDR NY-90-1: Drainage area.
GAGE.--Water-stage recorder. Datum of gage is NGVD of 1929. Prior to Feb. 27, 2002, at site 1,000 ft upstream at datum 10.00 ft lower.
REMARKS.--Prior to October 2002 published as maximum, minimum, and mean elevation. 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, 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, 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. Interruption of record was due to malfunction of recording instrument.
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, 29.4 °C, July 23, 2011; minimum, -0.3 °C, Mar. 3, 2009.

Peak Flow and Stage 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.
