  • January 22, 2018 - USGS Water Data availability during lapse in Federal funding

    Due to a lapse in Federal funding, the U.S. Geological Survey must suspend those parts of its data collection and distribution processes requiring human intervention. However, automated reporting and serving of telemetered data will continue.

    Users may note some degradation in the quality and completeness of real-time streamflow, groundwater and water-quality data from some reporting stations due to the suspension of field calibrations and adjustments, especially as high flows occur, aquatic vegetation becomes dominant, or ice forms in high altitude streams. The USGS will continue to monitor some performance aspects of its network using a skeleton workforce.

LOCATION.--Lat 43°18'41", long 73°52'02" referenced to North American Datum of 1983, Saratoga County, NY, Hydrologic Unit 02020002, on left bank 1.0 mi downstream from Stewarts Bridge, 1.1 mi west of Hadley, 1.4 mi upstream from mouth, and 1.5 mi downstream from Stewarts Bridge hydroelectric plant.
DRAINAGE AREA.--1,055 mi².
PERIOD OF RECORD.--September 1907 to current year. Published as "near Hadley" 1907-l910, "at Hadley" 1911-32 and "at Conklingville" 1932-52. Records published for present site and former site October 1951 to September 1952.
REVISIONS HISTORY.--WSP 1302: 1908. WSP 1432: 1910-12, 1916-21. WDR NY-83-1: 1968(M), 1971-72(M), 1976-77(M), 1979(M).
GAGE.--Water-stage recorder and crest-stage gage. Datum of gage is 582.00 ft above NGVD of 1929. Prior to Jan. 1, 1911, nonrecording gage at site about 1 mi upstream at different datum. Jan. 1, 1911 to Sept. 30, 1932, at site 0.8 mi downstream at datum 8.82 ft lower. Oct. 1, 1932 to Sept. 30, 1952, at site 3.6 mi upstream at datum 85.47 ft higher.
COOPERATION.--From Oct. 1, 1932 to Dec. 4, 1979, discharge computed by Board of Hudson River-Black River Regulating District from rating developed by U.S. Geological Survey. Since Dec. 4, 1979, discharge computed by U.S. Geological Survey.
REMARKS.--Flow regulated by Great Sacandaga Lake since Mar. 27, 1930 (station 01323500); discharge over spillway, part or all of several days in 1983, 1990, 1993, 2000, 2003-04, 2006-08, 2011 (only spillage since completion of Conklingville Dam in 1930). Extensive diurnal fluctuation caused by release of water from Great Sacandaga Lake, through Elmer J. West hydroelectric station directed by Board of Hudson River-Black River Regulating District and through Stewarts Bridge hydroelectric station.
Water Years 2014-16: Records good except those below about 50 ft³/s, which are fair.
EXTREMES FOR PERIOD OF RECORD.--Maximum discharge, since construction of Great Sacandaga Lake in 1930, 16,500 ft³/s, May 2, 2011, gage height, 10.40 ft; minimum, 4.2 ft³/s, May 4, 1985, Mar. 30, 31, Apr. 1-10, 11, 13, 14, 15, 1992.
EXTREMES FOR PERIOD PRIOR TO REGULATION.--Maximum discharge, prior to construction of Great Sacandaga Lake in 1930, about 35,500 ft³/s, Mar. 28, 1913, gage height, 12.36 ft, site and datum then in use.
