ALBANY—The New York Power Authority (NYPA), working with the New York State Canal Corporation, will oversee the seasonal installation of flashboards, buoys and the fish deterrent system at Crescent and Vischer Ferry dams, located on the Mohawk River in the Towns of Niskayuna, Clifton Park and Colonie, starting Monday, April 27.  

Staff members from NYPA’s Blenheim-Gilboa Pumped Storage Power Project will direct the work, which will be conducted by a maintenance crew from the New York State Canal Corporation’s Waterford Section Office, utilizing a self-propelled flat bottom boat, or scow.

Water levels at Vischer Ferry will begin to drop during the evening hours on Monday, April 27, in anticipation of the installation of the flashboards and buoys at Vischer Ferry Dam D beginning on Tuesday, April 28.

The maintenance crew is expected to continue the Vischer Ferry flashboard and buoy installations on Wednesday, April 29 and Thursday, April 30, at Dams E sand F, including the fish deterrent system at Dam F.  Water levels will begin to rise through the evening of Thursday, April 30 and continue through the morning of Friday, May 1. 

During the morning of Friday, May 1, water levels will begin to drop at Crescent pond where the maintenance crew will have moved to install flashboards and buoys during the afternoon.  Crescent pond will begin to rise in the evening on Friday, May 1 as river flow permits.

Throughout the flashboard installation process, water levels will remain above the Canal Corporation's minimum navigation levels above Locks E-6 and E-7.

Barring any complications or inclement weather, the installations will be completed by Friday, May 1, and the water levels restored.  Unforeseen precipitation and high water conditions may delay this schedule.

Any questions regarding this work please contact John Osinski, New York Power Authority, at 518-433-6742.
