Sainte-Anne Ouest River

The Sainte-Anne Ouest river rises at the mouth of Lake Annette (length: 1.4 kilometres (0.87 mi); altitude 626 metres (2,054 ft)). This lake is located on the southern slope of the watershed boundary with Batiscan Lake (Quebec). Its mouth is located at:

• 2.6 kilometres (1.6 mi) south of Batiscan Lake (Quebec);
• 25.0 kilometres (15.5 mi) northwest of the confluence of the Sainte-Anne Ouest river and the Neilson River;
• 47.6 kilometres (29.6 mi) north of the confluence of the Bras du Nord and the Sainte-Anne River.[1]

From the mouth of Lake Annette, the Sainte-Anne Ouest river flows over 40.9 kilometres (25.4 mi) generally southward entirely in the forest zone, with a drop of 427 metres (1,401 ft).[1]

The course of the Sainte-Anne Ouest river descends in the following segments:

Upper course of the Sainte-Anne Ouest river (segment of 15.9 kilometres (9.9 mi))

• 2.0 kilometres (1.2 mi) towards the south-east crossing Lake Querré, then Lake Fairchild (length: 2.2 kilometres (1.4 mi); altitude 687 metres (2,254 ft)) on 1.2 kilometres (0.75 mi)) to its mouth;
• 4.0 kilometres (2.5 mi) to the east, in particular by crossing the Lac Le Gardeur (length: 3.3 kilometres (2.1 mi); altitude 604 metres (1,982 ft)) over its full length to its mouth;
• 2.9 kilometres (1.8 mi) to the south in a deep valley, notably crossing an unidentified lake (length: 0.9 kilometres (0.56 mi); altitude 585 metres (1,919 ft)) on its full length, up to the outlet (coming from the east) of a set of lakes including Lac Nollet;
• 0.6 kilometres (0.37 mi) westward curving southwards, to the outlet of Cunningham Lake (coming from the northwest);
• 6.4 kilometres (4.0 mi) towards the south in particular by crossing Pinsart Lake (length: 0.8 kilometres (0.50 mi); altitude 534 metres (1,752 ft)), then branching towards west, to the outlet (coming from the northwest) of a set of lakes including Nessa, aux Bleuets, Gorren and Insipide;

Lower course of the Sainte-Anne Ouest river (segment of 25.0 kilometres (15.5 mi))

• 2.9 kilometres (1.8 mi) towards the southwest by collecting the discharge (coming from the northwest) from Lake Betty, then crossing Lake William (length: 1.3 kilometres (0.81 mi); altitude 491 metres (1,611 ft)) on 0.9 kilometres (0.56 mi) south-east to its mouth;
• 2.2 kilometres (1.4 mi) towards the south-east by crossing some rapids until the discharge (coming from the east) of two unidentified lakes;
• 2.8 kilometres (1.7 mi) to the south, in particular by crossing Lake Drucilla (length: 1.3 kilometres (0.81 mi); altitude 451 metres (1,480 ft)) on 0.9 kilometres (0.56 mi) to its mouth;
• 1.1 kilometres (0.68 mi) towards the west by forming a curve towards the north to go around a mountain, up to a bend of the river, corresponding to the discharge (coming from the northwest) of a set of lakes;
• 8.3 kilometres (5.2 mi) in a deep valley, first towards the south-east and bifurcating towards the south, up to the stream of Crapaud (coming from the north-east);
• 1.8 kilometres (1.1 mi) to the south in a deep valley and crossing some rapids, until the Red stream (coming from the west);
• 5.9 kilometres (3.7 mi) in a deep valley crossing some rapids, first towards the east by collecting the discharge (coming from the south) from an unidentified lake, bending towards the south-east by collecting the discharge (coming from the southwest) of a group of lakes, and bypassing an island at the end of the segment, to its mouth.[1]

The Sainte-Anne Ouest river flows at the confluence of the Neilson River; this confluence becomes the source of the Bras du Nord. From there, the current generally descends south following the course of the latter to the northwest bank of the Sainte-Anne River. From this last confluence, the current descends on 76.0 kilometres (47.2 mi) generally towards the south and the southwest by following the course of the Sainte-Anne river, until the northwest bank of St. Lawrence River.[1]

The toponym "Rivière Sainte-Anne Ouest" was formalized on December 5, 1968 at the Place Names Bank of the Commission de toponymie du Québec.[2]
