The River Portage, a tributary of the southwestern shore of the Petit Saguenay River flowing successively in the municipalities of L'Anse-Saint-Jean and Petit-Saguenay in the Le Fjord-du-Saguenay Regional County Municipality, in the administrative region of Saguenay-Lac-Saint-Jean, in Quebec, in Canada. The upper part of this river crosses the Zec de l'Anse-Saint-Jean.
The lower portion of the "rivière du Portage" Valley is indirectly served by Route 170 which passes on this point on the east bank of the Petit Saguenay River. The upper part, especially around the "Lac de la Rivière" is served by the "chemin du Portage". Some secondary forest roads serve the rest of the valley, especially in the zec.[2]
Forestry is the first economic activity in the sector; recreational tourism activities, second.
The surface of the Portage River is usually frozen from the beginning of December to the end of March, however, safe ice circulation is generally from mid-December to mid-March.

This headwater body is located between the Mont à l'Ours (Bear Mount) (880m (2,890feet)) and East Mount 712m (2,336feet)), in the southern part of Zec de l'Anse-Saint-Jean.

Lower section of the Portage River (segment of 23.4km (14.5miles))
