The main neighboring watersheds of the Gold River are: The rivière de l'Or draws its source from Lac du Huit located in the municipality of Adstock, east of the Thetford Mines mining area, east of Bécancour Lake, west of route 269.

[1] Its mouth is located on the south shore of the lake, at the end of the Baie des Bouleaux.

The Rivière de l'Or first flows on 1.2 kilometres (0.75 mi) towards the south to Baie des Fortin from lac à la Truite (length: 3.2 kilometres (2.0 mi); altitude: 379 metres (1,243 ft)) that the current crosses on 1.1 kilometres (0.68 mi), bypassing the Pointe du Fer à Cheval, towards the southwest to its mouth located in the extreme west Lake.

Then the river resumes its course on 4.4 kilometres (2.7 mi) towards the south-west, passing the east of Thetford Mines airport, passing west of Mont Adstock, then crossing the route 267, up to the Quenneville stream (coming from the west).

In its last segment, the Gold River flows on 1.9 kilometres (1.2 mi) towards the south, passing to the west of the Poudrier Hills, to empty at the bottom of a bay on the north shore of the Grand lac Saint François.
