It is a run-of-river generating station with an installed capacity of 752 megawatts (1,008,000 hp), a head of 17.99 meters (59.0 ft), and a reservoir of 26 square kilometers (10 sq mi).

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.
