The Waterford Flight is a set of locks on the Erie Canal in Waterford, New York. Erie Canal Locks E-2 through E-6 make up the combined flight at Waterford, which lifts vessels from the Hudson River to the Mohawk River, bypassing Cohoes Falls. Built in 1915, the Waterford Flight is still in use today as part of the New York State Canal System, which is open to public and commercial traffic. The Waterford Flight is the series of locks with the highest elevation gain relative to its length for any canal lock system in the United States.
