The river Rivière aux Outardes ( English Outardes River ) flows through the administrative regions Saguenay – Lac-Saint-Jean and Côte-Nord in the Canadian province of Québec .
The river has its origin in the Monts Otish in central Labrador . From there it flows exclusively in a southerly direction. It flows through the lakes Lac Plétipi and Lac des Îles Brûlées . It then widens in the form of the 650 km² dammed Outardes 4 reservoir . Finally, the Rivière aux Outardes flows into the confluence of the Saint Lawrence River at Pointe-aux-Outardes , about 20 km southwest of Baie-Comeau .
At its mouth, the Rivière aux Outardes widens and flows over a sandbank, so that the water here is very shallow. There are several islands in the estuary bay. Mention should be made here of Île Blanche , a 23 m high rock made of white granite, and Île de la Mine , a bare red rock 15 m high.
The river was originally called Cane or Caen by Jean Alfonse in 1544 . The name Rivière aux Outardes first appeared on the maps by Jacques-Nicolas Bellin from 1744 and 1764 . Today outardes is the Canadian-French word for Canada geese . The Innu named the river Pirebistibit, Peritibistokou, Pletipishtuk or Piletipîstuk Shipu .
The most important tributaries include:
- Rivière à l'Argent
- Rivière à Villéon
- Rivière du Bois Long
- Rivière Matonipi
As part of the Manic Outardes project , several dams and hydroelectric power stations were built along the river in the 1960s and 1970s. There are three hydropower plants operated by Hydro-Québec :
- Réservoir aux Outardes 2 - 3 Francis turbines, 523 MW , built 1974–1978 (above the mouth at Chute-aux-Outardes )
- Réservoir aux Outardes 3 - 4 Francis turbines, 1026 MW, built 1965–1969
- Réservoir aux Outardes 4 - 4 Francis turbines, 785 MW, built 1964–1969
