The Rivière Caniapiscau is a source river of the Rivière Koksoak in the administrative regions of Côte-Nord and Nord-du-Québec of the Canadian province of Québec . In the Cree language, the river name means "rocky point".
The river originally (before the construction of the Caniapiscau Dam and the discharge of the water) had its origin in Lac Sevestre 53 km southwest of Fermont on the Canadian Shield . The Rivière Caniapiscau flows below the Caniapiscau dam to the north through a wide wooded valley of glacial origin before it joins the Rivière aux Mélèzes to form the Rivière Koksoak.
Since 1985, the upper reaches of the Rivière Caniapiscau has been diverted to the La Grande Rivière river as part of the Baie James hydropower project . On June 13, 1997 the river section above the Caniapiscau reservoir was renamed Rivière René-Lévesque . Now 45 percent of the water flows to James Bay . The Caniapiscau Reservoir, which covers an area of 4,300 km² (or nine times the size of the original Lac Caniapiscau ), fills a depression in the highest part of the Canadian Shield . Before the diversion to James Bay, the catchment area of the Rivière Caniapiscau was 84,500 km², its mean discharge 1700 m³ / s.
