Geography

The main watersheds neighboring the "Rivière aux Montagnais" are:

The Montagnais river rises at the mouth of Lac Magny (length: 0.6 kilometres (0.37 mi); altitude: 499 metres (1,637 ft)). This misshapen lake has four bays; its mouth is located at the bottom of the south-eastern bay.

From its source (mouth of Lake Magny), the course of the Montagnais river descends on 27.4 kilometres (17.0 mi), with a drop of 99 metres (325 ft), according to these segments:

Upper part of Rivière aux Montagnais (segment of 6.7 kilometres (4.2 mi))

  • 0.5 kilometres (0.31 mi) south, to the north shore of Lac aux Cailloux;
  • 0.5 metres (1 ft 8 in) eastward across Lac aux Cailloux (length: 0.9 kilometres (0.56 mi) in the shape of a boot; altitude: 494 metres (1,621 ft)) until its mouth;
  • 2.4 metres (7 ft 10 in) towards the south-east, crossing across a large area of marsh, to the south shore of lac aux Montagnais;
  • 3.3 kilometres (2.1 mi) north, then north-west across Lac aux Montagnais (length: 3.8 kilometres (2.4 mi); altitude: 494 metres (1,621 ft)) to its mouth located at the bottom of a bay on the west shore;

Lower part of the Rivière aux Montagnais (segment of 20.7 kilometres (12.9 mi))

  • 0.7 kilometres (0.43 mi) towards the northwest, up to the Amitié stream;
  • 10.8 kilometres (6.7 mi) towards the northwest in particular by collecting the discharge (coming from the southwest) of the Potvin lake and by forming some serpentines, until its confluence of the ruisseau Contourné;
  • 2.6 kilometres (1.6 mi) south, then southwest up to a bend in the river;
  • 4.0 kilometres (2.5 mi) towards the northwest by forming some large coils and collecting the discharge (coming from the north) from lakes Couillard, Coulombe and Petit lac Coulombe, up to the discharge of the lake Corbeil;
  • 2.6 kilometres (1.6 mi) towards the northwest to a stream (coming from the north), then towards the west, forming a hook towards the northwest at the end of the segment, until its mouth.[1]

From the confluence of the Montagnais river, the current descends:
