Carillon hydroelectric generating station

The Carillon generating station (in French: centrale de Carillon) is a 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 m, and a reservoir of 26 km2. The dam spans the river between Carillon and Pointe-Fortune, Quebec.

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