Notice to Mariners

Champlain Canal – Waterford and Halfmoon

May 19, 2022

The Canal Corporation today announced that Locks C-1 in Waterford and C-2 in Halfmoon will have scheduled operations for all northbound recreational traffic throughout the navigation season.  Lock C-1 will pass northbound traffic daily on the odd hours (7am, 9am, 11am, 1pm, 3pm, 5pm, 7pm, and 9pm).  Lock C-2 northbound traffic will be locked through when all vessels from Lock C-1 arrive at Lock C-2.  Southbound traffic will remain on demand.  

Additionally, these locks will operate on a "double draining" procedure.  After northbound vessels enter the lock chamber, the lock will be filled, drained, and refilled before the vessels can exit the lock proceeding northbound.  For all southbound traffic, vessels can exit the lock after the initial draining.  A second refilling and draining of the lock will occur after all vessels have left the lock. 

These measures are being implemented as risk reduction strategies to mitigate the spread of the round goby, an aquatic invasive species, in the Champlain Canal.

In addition, mariners are advised that based on the initial eDNA sampling data, the round goby has not migrated north of the confluence of the Mohawk and Hudson Rivers in Waterford at this time; therefore, Locks C-7 and C-8 in Fort Edward will operate under normal on-demand locking procedures until further notice.

Mariners may learn how they can help mitigate the spread of aquatic invasive species here.
