This river crosses successively the cantons of Charron and Ducharme. This river is part of the Ashuapmushuan Wildlife Reserve. Forestry is the main economic activity of this valley; recreational tourism activities, second.
A secondary forest road (heading north-east) that connects to route 167 serves the upper part of the "Coquille River" valley passing north of Lake Liasse and South of "Coquille Lake". Route 167 between Chibougamau and Saint-Félicien, Quebec passes on the west side of the lower part of the river.
The surface of the Coquille River is usually frozen from early November to mid-May, however, safe ice circulation is generally from mid-November to mid-April.

The mouth of this head lake is located at:

- 39.2 kilometres (24.4 mi) northwest of the mouth of the Normandin River (confluence with Ashuapmushuan Lake.
From the mouth of "Coquille Lake", the "Coquille River" flows over 20.5 kilometres (12.7 mi) according to the following segments:
- 4.7 kilometres (2.9 mi) southwesterly in Charron Township forming a southeasterly curve in marsh areas to the northern limit of Ducharme Township, corresponding to the dump (coming from the South-East) of "Lac des Charagnes";
- 4.8 kilometres (3.0 mi) westward in Charron township, including crossing Pommelé Lake (length: 0.9 kilometres (0.56 mi); altitude: 407 metres (1,335 ft) ) to the northern limit of the township of Ducharme;

From there, the current flows south-east along the Normandin River on 38.7 kilometres (24.0 mi) to the northwestern shore of Ashuapmushuan Lake. Then, the current flows through the Ashuapmushuan River which flows to Saint-Félicien, Quebec on the west shore of Lac Saint-Jean.
