The Caniapiscau Reservoir is a reservoir on the upper Caniapiscau River in the Côte-Nord administrative region of the Canadian province of Quebec. It is the largest body of water in Quebec and the second largest reservoir in Canada.
The Caniapiscau Reservoir, formed by two dams and forty-three dikes, is the largest reservoir in surface area of the James Bay Project. As headpond, it feeds the power plants of the La Grande complex in the winter and provides up to 35% of their production. Its total catchment area is about 36,800 square kilometres.
The reservoir was named after Lake Caniapiscau that was flooded during the formation of the reservoir. The name is an adaptation of the Cree or Innu toponym kâ-neyâpiskâw, which means "rocky point".
