FOR IMMEDIATE RELEASE

ALBANY—The New York Power Authority (NYPA), working with the New York State Canal Corporation, will oversee the water drawdown for the seasonal removal of flashboards and fish bypass systems at Vischer Ferry and Crescent dams beginning on Monday, Nov. 26. Flashboards, used to regulate water levels at the hydroelectric power plants, seasonally raise the pond level upstream of the Crescent and Vischer Ferry Dams.

The Vischer Ferry Dam (Lock 7) spans the Mohawk River between Vischer Ferry, Saratoga County, and Niskayuna, Schenectady County. The Crescent Dam (Lock 6) is between Crescent, Saratoga County, and Colonie, Albany County.

The schedule is:

Monday, Nov. 26:
PM water levels at Vischer Ferry drop to elevation 211 feet (ft.) by Tuesday AM. This lowering represents a reduction of approximately 2 ft. below water levels normally observed during the canal navigation season.

Tuesday, Nov. 27:       
AM water levels at Vischer Ferry rise to 213.3 ft.  AM water levels at Crescent drop to 0.5 ft. below crest, elevation 183.5 ft.
