ALBANY—The New York Power Authority (NYPA) will oversee the water drawdown to install flashboards at the Vischer Ferry and Crescent dams beginning on Tuesday, May 7. Flashboards are plastic and/or wooden planks that are installed in the spring to raise water levels upstream of the dams for navigation purposes. These activities will affect water levels which may affect marinas, boats and docks.

 

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 Waterford, Saratoga County, and Colonie, Albany County.

 

Monday, May 6:

A gradual drawdown begins at the Vischer Ferry dam as water levels between Erie Canal Locks E7 and E8 drop between 6 inches and 2.0 feet (depending on river flows) below water levels normally observed during the canal non-navigation season. (Elevation 210.5’ Barge Canal Datum).

 

Tuesday, May 7:       
Morning water levels at Vischer Ferry at 6 inches below dam crest to allow for installation of the flashboards at Dam D (Elevation 210.5’ Barge Canal Datum). Evening: Water level at Vischer Ferry rise approximately 7 inches. (Elevation 211.1’ Barge Canal Datum).

 

Wednesday, May 8:

Morning water levels at Vischer Ferry drop approximately 7 inches to allow for installation of flashboards at Dam F and the fish deterrent system, (Elevation 210.5’ Barge Canal Datum). Evening water levels at Vischer Ferry rise approximately 7 inches. (Elevation 211.1’ Barge Canal Datum).

 

Thursday, May 9:

Morning water levels at Vischer Ferry drop approximately 7 inches to accommodate the installation of flashboards at Dam E. (Elevation 210.5’ Barge Canal Datum). Afternoon: Work barge travels from Lock E7 to Lock E6 at the Crescent dam. Evening water levels at the Vischer Ferry dam rise approximately 7 inches (Elevation 211.1’ Barge Canal Datum).

 

Friday, May 10:

Morning water levels at Vischer Ferry rise to Navigation season levels from Elevation 211.1’ Barge Canal Datum to Elevation 213.3’ Barge Canal Datum. At Crescent, a drawdown begins as water levels between the Erie Canal Locks E6 and E7, are lowered.  Water levels will drop between 6 inches and 2 feet, depending on river flows, to 6 inches below the dam crest to accommodate the installation of flashboards at Crescent dam (Elevation 183.5 Barge Canal Datum). Evening water levels at Crescent pond rise to top of flashboards, navigation season levels, as river flows permit. (Elevation: 185.0’ Barge Canal Datum).

Barring any complications or inclement weather, the installation of the flashboards will be completed by May 10. 2019.  Unforeseen precipitation and high water conditions may delay this schedule.  Any questions regarding this work should be directed to Mario Roefaro, New York Power Authority at 315-792-8335.
