- 6.6 km (4.1 mi) south of the confluence of the "Bras à Pierre" and the Saint-Jean River.[2]
From the mouth of its source, the course of "Bras à Pierre" descends on 9.0 km (5.6 mi), according to a drop in level of 194 m (636 ft) according to the following segments:
- 3.0 km (1.9 mi) towards the north especially in the marsh area in a valley in a valley surrounded by high mountains, collecting the discharge (coming from the west) of a small lake, as well as the discharge (from the east) from another small lake, to a stream (from the east);
- 0.4 km (0.25 mi) westward, to a stream (coming from the west);
- 5.6 km (3.5 mi) towards the north in a valley between the mountains and forming a hook towards the west and a loop towards the east at the end of the segment, up to the mouth.[2]

- follows the course of the Saint-Jean River on 26.0 km (16.2 mi) generally towards the northeast;
- crosses Anse Saint-Jean on 2.9 km (1.8 mi) to the north;
