FOR IMMEDIATE RELEASE

ALBANY—The New York Power Authority (NYPA), working with the New York State Canal Corporation, will begin the seasonal removal of the remaining flashboards and fish deterrent system at Vischer Ferry beginning on Tuesday, Nov. 8.  The flashboards at Crescent Dam will then be removed on or about Dec. 9. The Crescent and Vischer Ferry dams are located on the Mohawk River in the Towns of Niskayuna, Clifton Park and Colonie. 

Governor Andrew M. Cuomo announced, on Sept. 26, an extended navigation season to assist boaters stranded by flood damage to portions of the Eastern Erie Canal. The water levels resulting from the removal of the flashboards will be sufficient for the passage of vessels during the extended navigation season that starts in late November and runs through mid-December. Typically, the navigation season on the Canal system runs from May 1 through November 15.

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.

Flashboards, used to regulate water levels at the hydroelectric power plants, seasonally raise the pond level upstream of the Crescent and Vischer Ferry Dams.  Many of the flashboards were damaged by debris washed into the river during the flood.

The schedule is:

Monday, Nov. 7:
PM water levels at Vischer Ferry drop to elevation 211 feet (ft.) by Tuesday AM.

Tuesday, Nov. 8:       
AM water levels at Vischer Ferry drop to 0.3 to 0.5 ft. below crest.  Removal of flashboards at Vischer Ferry is started.  PM water levels at Vischer Ferry rise to 0.1 ft. above crest.

Wednesday, Nov. 9: 
AM water levels at Vischer Ferry drop to 0.3 to 0.5 ft. below crest.  Removal of flashboards at Vischer Ferry continues.  PM water levels at Vischer Ferry rise to 0.1 ft. above crest.

Thursday, Nov. 10:
AM water levels at Vischer Ferry drop to 0.3 to 0.5 ft. below crest.  Removal of flashboards and the fish deterrent system at Vischer Ferry is completed.  PM water levels at Vischer Ferry return to crest, elevation 211.0 ft.  

Approx. Friday, Dec. 9:
AM water levels at Crescent drop to 0.5 ft. below crest, elevation 183.5 ft.  Removal of flashboards at Crescent is completed.  PM water levels at Crescent rise to crest, elevation 184.0 ft.  

Barring any complications or inclement weather, the removal of the flashboards and fish deterrent systems will be completed at Vischer Ferry by Monday, Nov. 10 and at Crescent by Dec. 9.  Unforeseen precipitation and high water conditions may delay this schedule.  Any questions regarding this work should be directed to John Osinski in NYPA’s Albany Office at 518-433-6742.
