Forestry is the main economic activity in this valley; recreational tourism, second.

The surface of the Métabetchoune River (except the rapids zones) is usually frozen from the end of November to the beginning of April, however the safe circulation on the ice is generally done from mid-December to the end of March.

Geography

The main watersheds neighboring the Métabetchouane Est river are:

The Métabetchouane Est River takes its source at the mouth of "Lac des Hautes des Terres" (length: 1.1 km (0.68 mi); altitude: 819 m (2,687 ft)). Enclosed between mountains, this lake is linked on the north side by a small stream with the "Lac de la Hauteur" which turns out to be the head lake of the rivière aux Écorces du Milieu. The mouth of "Lac des Hauts des Terres" is located: 2.5 km (1.6 mi) south of the source of the source of rivière aux Écorces du Milieu, at 2.9 km (1.8 mi) northwest of Lac Chagnon, 4.3 km (2.7 mi) northeast of Lac Tentant and 37.4 km (23.2 mi) northeast.

From its source, the course of the Métabetchouane East river descends on 54 km (34 mi), with a drop of 375 m (1,230 ft), according to the following segments:

Upper course of the Métabetchouane East River (from its source) (segment of 18.4 km (11.4 mi))

  • 1.8 km (1.1 mi) southwards crossing 0.7 km (0.43 mi) on Lake Mousseau, then Lake Aramis, to the outlet (coming from the north-west) from Lakes Athos and Porthos;
  • 1.5 km (0.93 mi) to the south, forming a large S, up to the outlet (coming from the east) of Lac Bourbier;
  • 2.4 km (1.5 mi) towards the west by forming a hook towards the south and meandering, until the outlet (coming from the southwest) of lakes Fretin, Tentant and Petit lac Tentant;
  • 2.6 km (1.6 mi) north-east, to the outlet (coming from the north-east) from Lake Sigma;
  • 4.6 km (2.9 mi) to the west, collecting the outlet (coming from the south) from Lac des Margouilies, and branching northwest to the Gratia stream (coming from the north);
  • 5.5 km (3.4 mi) south-east, then south by collecting the discharge (coming from the east) from Badaillac, Lime and Frêle lakes, to the north shore of Missip lake;

Intermediate course of the Métabetchouane East river (segment of 19.3 km (12.0 mi))

  • 6.5 km (4.0 mi) to the west, sometimes winding and collecting the discharge (coming from the south-east) from the Nourrains and Bocage lakes;
  • 2.6 km (1.6 mi) south-west, then north-west, up to Maria stream (coming from the north);
  • 4.6 km (2.9 mi) north-west, up to a bend in the river;
  • 5.6 km (3.5 mi) south-west, to the outlet (coming from the north-west) from lakes Boisseau, Dunoyon and Étang Florissant;

Lower course of the Métabetchouane Est river (segment of 16.3 km (10.1 mi))

  • 3.9 km (2.4 mi) first on 1.8 km (1.1 mi) towards the south-west in a deep valley up to a bend of the river; then on 2.1 km (1.3 mi) towards the south-east, then the south-west, up to the Liane stream (coming from the south-east);
  • 7.8 km (4.8 mi) towards the southwest by forming a large S, crossing a few series of rapids then forming a loop towards the southeast, until the outlet (coming from the north) from the Lake Raidillon;
  • 4.6 km (2.9 mi) to the southwest by forming serpentines at the end of the segment near a marsh area, until it meets the Métabetchouane River (coming from the southeast).[1]

From the confluence of the Métabetchouane East river, the current descends the Métabetchouane North River on 131.5 km (81.7 mi) to the south shore of lac Saint-Jean; from there, the current crosses the latter on 22.8 km (14.2 mi) towards the northeast, then borrows the course of the Saguenay River via La Petite Landfill on 172.3 km (107.1 mi) until Tadoussac where it merges with the Saint Lawrence estuary.[1]
