Moses-Saunders Power Dam, Hydroelectric dam on St. Lawrence River, Ontario and New York
Moses-Saunders Power Dam is a concrete structure that spans the St. Lawrence River between New York and Ontario, controlling water flow between the two regions. The installation includes multiple spillways and turbine chambers built into the main structure.
Construction started in 1954 as part of the Saint Lawrence Seaway project to improve navigation and power generation. Its completion in 1958 created a new reservoir and permanently altered the river's water dynamics.
The dam is named after two engineers and represents shared water management between the US and Canada. It stands as a daily reminder of cooperation across the border for the communities it serves.
The site is best viewed from the shoreline or nearby viewpoints to see the full structure. Visitors should be aware that direct access to the facility itself may be restricted for safety reasons.
The facility includes specialized passages for American eels that allow them to complete their annual migrations. These channels were specifically engineered to protect this fish population despite the dam's presence.
