LOCATION.--Lat 42°49'45", long 73°40'00"
referenced to North American Datum of 1927, Saratoga County, NY,
Hydrologic Unit 02020003, 0.4 mi upstream from dam at Lock 1 of the
Champlain (Barge) Canal, 2.8 mi northeast of Waterford, and 3.4 mi
downstream from dam at Lock 2 of the Champlain (Barge) Canal.
DRAINAGE AREA.--4,605 mi2.
PERIOD OF RECORD.--October 1887 to September 1956, October 1976
to current year. Prior to October 1976, published as "at
Mechanicville" (01335500, drainage area 4,500 mi2).
Daily discharge records from October 1976 to September 1981 are
published with suspended-sediment data as 01335770 Hudson River at
REVISED RECORDS.--WDR NY-99-1: 1998.
GAGE.--Water-stage recorder. Since October 1, 1998,
supplementary water-stage and taintor gate-position recorders, 0.4 mi
downstream at dam at Lock 1. Datum of gage is NGVD of 1929. Prior to
October 1976, various gages at site 5.8 mi upstream at different datum.
Prior to February 1978, nonrecording gage 200 ft downstream.
REMARKS.--Records fair except those for estimated daily
discharges, which are poor. Flow regulated appreciably by Great
Sacandaga Lake since March 1930 (see station 01323500) and Indian Lake
(see station 01314500). Diurnal fluctuation caused by powerplants
upstream from station. Water is diverted into St. Lawrence River basin
through Glens Falls feeder, Bond Creek, and Champlain (Barge) Canal,
and occasionally may be received from that basin through summit level
of Champlain (Barge) Canal at Dunham Basin. Water-discharge data for
July 1992 through May 1994 based on records for Hudson River at
Stillwater (01331095) and Hoosic River near Eagle Bridge (01334500) due
to reconstruction of dam at Lock 1. Satellite and telephone gage-height
telemeter at station.
EXTREMES FOR PERIOD OF RECORD.--Maximum discharge since
construction of Great Sacandaga Lake, 118,000 ft3/s, Jan. 1,
1949; maximum gage height, 36.38 ft, May 30, 31, 1984; minimum daily
discharge, 614 ft3/s, Feb. 1, 1931; minimum instantaneous
discharge not determined.
EXTREMES FOR PERIOD PRIOR TO REGULATION.--Maximum discharge
prior to construction of Great Sacandaga Lake, 120,000
ft3/s, Mar. 28, 1913.
