Saguenay catchment area

The Rivière Saguenay ( English Saguenay River ) is a river in the Canadian province of Québec . The name means “where the water comes out” in the Montagnais language .

River course

The Rivière Saguenay is formed by the confluence of the two outflow arms of Lac Saint-Jean - La Grande Décharge and La Petite Décharge - east of Alma . After about 60 km it flows into the Fjord du Saguenay at Saint-Fulgence . This is usually added to the Rivière Saguenay river, so that the actual confluence with the St. Lawrence River is near Tadoussac .

Its catchment area is 88,000 km². Its mean flow rate is 1300 m³ / s, but it can rise to 3000 m³ / s. The 100 m difference in altitude between Lac Saint-Jean and the fjord are used by several run-of-river power plants. The two right tributaries Rivière aux Sables and Rivière Chicoutimi drain the Lac Kénogami reservoir south of Saguenay .

Fjord du Saguenay

The Fjord du Saguenay (or Saguenay Fjord for short ) is 100 km long, up to 278 m deep and up to 3 km wide. It flows into the St. Lawrence River near Tadoussac. In the western part, a 10 km long arm branches off to the southwest, the “ Baie des Ha! Ha! Into which the Rivière Ha! Ha! flows out. The spring tidal range is 5.5 m at the mouth of the fjord at Tadoussac and 6.3 m in the lower part of the Saguenay River at Chicoutimi . The fjord and the river are navigable for ocean-going ships as far as Chicoutimi. The mixing of cold fresh and salt water by the tides makes the fjord mouth an important feeding area for various whale species , especially for white whales .

The Saguenay Fjord is part of the Saguenay – Saint-Laurent Marine Park ( Parc marin du Saguenay – Saint-Laurent ). The banks of the fjord and the surrounding hills form the Parc national du Fjord-du-Saguenay .

Hydropower plants

There are two dams and associated hydroelectric power stations along the river. They are operated by Rio Tinto Alcan and are on the same level at Jonquière .

  • Barrage de Chute-à-Caron ( ) with 224 MW, since 1931, 48.8 m head, maximum flow 585 m³ / s
  • Barrage Shipshaw ( ) with 896 MW, since 1943, 12 turbines, 64 m head, maximum flow 1645 m³ / s
