The Carillon Generating Station is a run of the river hydroelectric power station on the Ottawa River near Carillon, Quebec, Canada. Built between 1959 and 1964, it is managed and operated by Hydro-Québec. It is a run-of-river generating station with an installed capacity of 752 MW, a head of 17.99 meters (59.0 ft), and a reservoir of 26 square kilometers (10 sq mi).[1] The dam spans the river between Carillon and Pointe-Fortune, Ontario.

Upon completion, the dam raised the water level by over 62 feet (19 m) at Carillon and over 9 feet (2.7 m) at Grenville. This inundated the rapids of Long-Sault, transforming them into calm (deeper) water. The dam also includes a modern lock that facilitates traffic up the Ottawa River, superseding the Carillon Canal.
