Geography

edit

The Hidden River rises at the mouth of Valmont Lake (length: 0.7 kilometres (0.43 mi); altitude: 122 metres (400 ft)). This lake is located in the southern part of a large swamp area which extends in the sector of Shawinigan-Sud, in Lac-à-la-Tortue and Saint-Narcisse. This source is located at:

  • 4.1 kilometres (2.5 mi) north of the village of Notre-Dame-du-Mont-Carmel;
  • 8.7 kilometres (5.4 mi) east of downtown Shawinigan-Sud;
  • 10.0 kilometres (6.2 mi) south-east of the village center of Saint-Narcisse.

From its source, the Cachée river flows on 17.6 kilometres (10.9 mi), according to the following segments:

  • 3.7 kilometres (2.3 mi) towards the south-west, by crossing the chemin du rang Saint-Louis, up to the Lamothe road bridge;
  • 2.6 kilometres (1.6 mi) south-west, up to the Chemin Saint-Louis road bridge;
  • 2.9 kilometres (1.8 mi) (or 1.8 kilometres (1.1 mi) in a direct line) to the south, crossing route 157 and winding up to veterans road bridge;
  • 8.4 kilometres (5.2 mi) (or 4.1 kilometres (2.5 mi) in a direct line) towards the south-west, winding up to its confluence.[2]

The Cachée river flows on the east bank of the Saint-Maurice river upstream of the La Gabelle dam. The confluence of the Cachée river is located upstream of the La Gabelle dam at:

  • 0.8 kilometres (0.50 mi) upstream of the La Gabelle dam;
  • 2.2 kilometres (1.4 mi) south-east of the railway bridge spanning the Saint-Maurice river.

Toponymy

edit

The sinuousness of its course at the bottom of a flow in the lower part explains the hidden character of the river. The Hidden Coast of the old road segment connecting Shawinigan-Sud and Cap-de-la-Madeleine included curves at the bottom of the flow which formerly caused several road accidents.
