The eastern part of the Amédée river valley is served by forest roads and indirectly by the Trans-Québec-Labrador road; the lower part, by the route 138.[1]

Besides the urban area (Baie-Comeau sector) at the end of the segment, forestry is the main economic activity in this valley.[2]

The surface of the Amédée River is usually frozen from the beginning of December to the end of March, except the rapids areas; however, safe circulation on the ice is generally from mid-December to mid-March.

Toponymy

The Amédée river is named in honor of Amédée Couillard-Després, first manager of the sawmill built at the mouth of the river by Damase and Henri Jalbert in 1898.[3],[4]

The toponym “Amédée river” was formalized on December 5, 1968 at the Place Names Bank of the Commission de toponymie du Québec.[5]

Geography

The Amédée River is part of the Manicouagan River watershed. It is supplied by Lake Amédée (length: 2.6 km (1.6 mi); altitude: 81 m (266 ft)) located at 7.9 km (4.9 mi) northwest of downtown town of Baie-Comeau. Lake Amédée is supplied by:

  • north-west bank: two streams,
  • north shore: the outlet of 5 lakes, the outlet of Lake Hibou, the outlet of Lake Marcel;
  • east bank: the outlet of a stream, the outlet of two lakes, the outlet of two lakes.

The Amédée river has a free weir-type dam to regulate the water flow.[6] The river ends with falls located near the site named Vieux Poste before emptying into the St. Lawrence River.

The Amédée river flows flows on 10.1 km (6.3 mi) with a drop of 79 m (259 ft), according to the following segments:

  • 5.9 km (3.7 mi) generally towards the south-east, forming some coils, until the beginning of a widening of the river;
  • 2.7 km (1.7 mi) towards the south-east forming a widening of the river, first on 1.4 km (0.87 mi) by collecting the Couillard stream (coming from the north) to route 138; then on 1.3 km (0.81 mi) towards the south-east passing in an industrial zone (located on the west side of the river) and collecting Le Petit Bras (coming northeast) to the dam;
  • 1.5 km (0.93 mi) towards the south-east crossing two zones of rapids and forming a loop towards the east at the end of the segment, until its mouth.[2]

The Amédée river flows at the bottom of a small bay on the north shore of the Gulf of St. Lawrence, either:
