The "Grand-Saint-Louis river" originates in an agricultural area on the border of Saint-Sylvère and Bécancour. This area is located near the Route des Peupliers, north of the Bécancour River and west of the village of Bécancour. In this head area (east of the Bécancour River, four roads are designated by tree names: poplars, cherry trees, beech trees, elms and spruce trees.
From the intermunicipal limit between Saint-Sylvère and Bécancour, the course of the river flows in forest and agricultural area, over 12.9 km, with a drop of 60 metres (200 ft), according to the following segments:
- 1.3 km north-west, in a forest area, to the bridge over the Route des Peupliers;
- 1.7 km to the northwest, in an agricultural area up to the beech road;
- 2.1 km north, to route 226;
