[1] Forestry is the main economic activity in the upper half of this valley; agriculture, in the lower part.

[2] The surface of the Rivière à la Chasse is usually frozen from the beginning of December to the end of March, except the rapids; however, traffic on the ice is generally safe from mid-December to mid-March.

The Rivière à la Chasse originates at the confluence of several forest streams (altitude: 270 m (890 ft)) in Sainte-Hedwidge.

This confluence is located between the villages of Saint-Prime and Pointe-Bleue, either: From the mouth of Rivière à la Chasse, the current crosses Lac Saint-Jean to the east for 39.5 km (24.5 mi) to the northeast, follows the course of the Saguenay River via the Petite Décharge on 172.3 km (107.1 mi) eastwards to Tadoussac where it merges with the Estuary of Saint Lawrence.

[2] The toponym "rivière à la Chasse" was formalized on December 5, 1968, at the Place Names Bank of the Commission de toponymie du Québec.
