The course of the Couchepaganiche river crosses the township of Caron.

The lower part of the Couchepaganiche river valley is served by the route 169 which runs along the southeast shore of lac Saint-Jean. This valley is also served by some secondary forest roads, especially for forestry and recreational tourism activities.

Forestry and agriculture are the main economic activities in this valley; recreational tourism, second.

The surface of the Couchepaganiche River is usually frozen from the beginning of December to the end of March, however the safe circulation on the ice is generally made from mid-December to mid-March.

Toponymy 
Joseph-Laurent Normandin notes in his "Travel Journal"... from 1732 the name "Guspajganichiche" to designate this river. In his deposition of 1823, the explorer François Verreault affirms that this small river is called "Koushpygish", Innu term meaning "where the water rises a little". However, the “Little Dictionary of Geographical Names of the Saguenay”, published in 1944, notes that “Koushpaiganish” is an Innu word meaning “small river of embarkation”, a meaning also attributed to him by the explorer Normandin.

The toponym “Rivière Couchepaganiche” was formalized on December 5, 1968, at the Place Names Bank of the Commission de toponymie du Québec.
