Flashboards to be Reinstalled at Crescent and Vischer Ferry Dams, Beginning July 29
- No Impact on Boating in Navigational Channel Anticipated -
July 24, 2014
FOR IMMEDIATE RELEASE
ALBANY—The New York Power Authority (NYPA), working with the New York State Canal Corporation, plans to reinstall flashboards at the Crescent and Vischer Ferry Dams located on the Mohawk River in Niskayuna, Clifton Park and Colonie beginning July 29.
Several of the flashboards were strained due to high river flows caused by heavy rains earlier this summer and will be reinforced then reinstalled. The dams sustained no damage. The work is not expected to impact boating in the navigational channel. Flashboards are plastic and/or wooden planks that are installed in the spring to raise water levels upstream of the dam.
Staff members from NYPA’s Blenheim-Gilboa Pumped Storage Power Plant will direct the work, which will be conducted by a maintenance crew from the Waterford Maintenance Section of the Canal Corporation using a self-propelled, flat bottom boat or scow.
Water levels at the Vischer Ferry Dam in Niskayuna will drop to six inches below the top of the dam during the evening of Tuesday, July 29, to allow for reinstallation of the flashboards on July 30 and 31.
On Friday, August 2, the pool at the Crescent Dam in Halfmoon will be drawn down six inches below the top of the dam to complete the reinstallation of flashboards at that location. Following the work, water levels at the Crescent and Vischer Ferry Dams will be restored as river flows permit.
Unforeseen precipitation and high water conditions may delay this schedule. The adjusted water levels may affect some boats in shallow waters. They should have no impact on boating within the navigation channel.
Any questions regarding this work should be directed to Dave Weiman, New York Power Authority at 518-287-6340.
