Portneuf River East


The Portneuf East River is a tributary of the Portneuf River, flowing on the northwest shore of the Saint Lawrence River, in the territory from Lac-au-Brochet, in the La Haute-Côte-Nord Regional County Municipality, in the administrative region of Côte-Nord, Quebec, Canada.
From route 138, the forest road “Chemin de la Rivière des Cèdres” goes up the valley of the Portneuf river to the mouth of the Rivière des Cèdres. From there, a secondary forest road goes north-west to the peninsula south of the mouth of the Portneuf East river. The mountainous topography of the Portneuf East River hinders the development of a forest road for this valley.
Forestry is the main economic activity in the sector; recreational tourism, second.
The surface of the Portneuf East River is usually frozen from the end of November to the beginning of April; however, safe circulation on the ice is generally made from mid-December to the end of March.
