The lower part of the valley of this watercourse is served by route 138 which runs along the northwest shore of the St. Lawrence River and by the road of the rang Sainte-Anne. The "chemin des érables" and Port-au-Saumon Lake Road serve the upper reaches of this stream.

Forestry is the main economic activity of the sector; recreational and tourism activities (including vacationing around Lac au Saumon), second.

The surface of this stream is generally frozen from mid-December to late-March. Nevertheless, safe ice traffic is generally from late December to mid-March.

The Port-au-Saumon River has its source at "Lac du Port-au-Saumon" (length: 0.7 km (0.43 mi); altitude: 288 m (945 ft)) which is clover-shaped deformed and in forest area. The resort is developed around the northern appendage of the lake. The mouth of the lake is at the bottom of the eastern appendage.

From the mouth of Port-au-Saumon Lake, the course of the Port-au-Saumon River descends by traveling 20.8 km (12.9 mi) according to the following segments:

Upper part of the Port au Saumon River (segment of 15.1 km (9.4 mi))

  • 4.3 km (2.7 mi) easterly along the south side of Port-au-Saumon Lake Road, then south-east, winding to the confluence of the Lake of Port au Saumon (coming from the north);
  • 3.3 km (2.1 mi) southeast winding to a creek (coming from the west);
  • 7.5 km (4.7 mi) south winding to a creek (coming from the west);

Lower part of the Port au Saumon River (segment of 5.7 km (3.5 mi))

  • 4.9 km (3.0 mi) northeasterly under the Sainte-Anne Rang Road Bridge, forming a southerly curve across a series of rapids over this segment to the bridge of the Route 138 (Malcom-Fraser Boulevard);
  • 0.8 km (0.50 mi) southeasterly crossing a series of rapids to the east shore of Port-au-Saumon Inlet which is interelected in the Gulf of St. Lawrence. Sabere and Camarine Islands guard the exit of this bay.[3]
