The heart of the St. Lawrence-FDR Power Project is the Robert Moses-Robert H. Saunders Power Dam which first generated power in 1958. It is one of North America's largest-and most economical-power producers. The entire project encompasses over 37 miles of the St. Lawrence River Valley and includes two control dams and three huge locks used by ocean-going cargo ships and tankers. The visitors center at the power dam features state-of-the-art exhibits on energy, electricity and the area's history. Learn how the power dam and the St. Lawrence Seaway were built, in what was one of the largest construction projects of its type in the world.
From the Dwight D. Eisenhower Lock Viewing Deck and Interpretive Center you can watch huge tankers and ships being lifted or lowered 42 feet in the lock chamber. A parking area on the north side of the lock provides a vantage point when the viewing deck is closed. Call ahead to determine when ships will be arriving at the locks, 315-769-2422.
