Rivière au Saumon (Saint-Jean River tributary)

The rivière au Saumon (English: Salmon River) is a tributary of the Saint-Jean River, flowing in the unorganized territory of Lac-Jérôme, in the Minganie Regional County Municipality, in the administrative region of Côte-Nord, in the province of Quebec in Canada.

Forestry is the main economic activity in this valley.

Geography
The salmon river draws its source at the mouth of a small lake (length: 0.4 km; altitude: 490 m) in the unorganized territory of Lac-Jérôme. The mouth of this lake is located at:
 * 93.3 km north-west of the village center of Havre-Saint-Pierre;
 * 72.5 km north-west of the mouth of the Saint John River;
 * 47 km north-west of the mouth of the Salmon river.

From its source, the Salmon river flows over 71.7 km with a drop of 468 m, entirely in the forest zone, according to the following segments:

Upper course of the salmon river (segment of 30.6 km)


 * 9.4 km first south to the outlet (coming from the southwest) of two lakes; then south-east to the lake ?; then south across the lake? (length: 5.2 km; altitude: 376 m), to its mouth. Note: This lake is characterized by a first peninsula attached to the east shore, stretching to the southwest on 1.1 km and a second peninsula attached to the west shore, s' stretching over 0.7 km to the east;
 * 6.4 km first towards the south-east, crossing a small triangular lake at the end of the segment, to its mouth;
 * 14.8 km first south-east on 7.7 km to the northwest shore of Lac Collas; then east and south across Collas Lake (length: 7.1 km matching the shape of a soup ladle with the handle on the south side; altitude: 274 m) over its full length to its mouth. Note: this lake receives 5 lake discharges, the largest of which comes from the south;

Lower course of the salmon river (segment of 41.1 km)


 * 10.2 km towards the east by forming a loop towards the north, followed by another towards the south to bypass a mountain, collecting the discharge (coming from the north) from Robin lake, crossing the lake Le Bouthiller (length: 1.7 km; altitude: 249 m) on 2.8 km, to its mouth;
 * 8.9 km first towards the east to a bend in the river corresponding to the outlet (coming from the east) of several lakes; then south, crossing Renfrew Lake (length: 3.6 km; altitude: 223 m) on 2.8 km, to its mouth. Note: Renfrew Lake is characterized by a large rectangular peninsula attached to the west shore, stretching for 1.1 km to the east; which gives the lake the shape of a question mark backwards;
 * 16.8 km towards the south-east by collecting the discharge (coming from the north) of Lake Esnault and the discharge (coming from the southwest) of a set of lakes, up to the discharge (from the northwest) of Lac Douayren;
 * 5.2 km towards the east in a deep valley, forming a loop towards the north, then curving towards the south-east, until its mouth.

The Salmon River flows on the west bank of the Saint-Jean River, about halfway between the southern limit of Labrador and the north shore of the Gulf of Saint Lawrence. This confluence is located at:


 * 27.9 km north-west of the village center of Mingan;
 * 32.5 km north of the mouth of the Saint-Jean river (i.e. near the village of Rivière-Saint-Jean);
 * 13 km west of Manitou Lake which is part of the hydrographic side of the Mingan River.

From the mouth of the Salmon river, the current descends the course of the Saint-Jean River towards the southwest on 43.4 km, to the north shore of Gulf of Saint Lawrence.
