mi northeast of Waterford, and 3.4 mi downstream from dam at Lock 2 of
the Champlain (Barge) Canal.
PERIOD OF RECORD.--
October 1887 to September 1956, October 1976
to current year. Prior to October 1976, published as "at

). Daily discharge records from October 1976 to September

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. October 1976
to January 1978, nonrecording gage 200 ft downstream.
Flow regulated appreciably by Great Sacandaga Lake
since March 1930 (station 01323500) and Indian Lake (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
