Geography

The Thompson River originates in Thompson Lake (length: 2.1 km (1.3 mi); altitude: 379 m (1,243 ft)) which is located in the territory of zec Lesueur, in the unorganized territory of Lac-Douaire. This deformed lake made in length includes a peninsula attached to the eastern shore and stretching for 0.4 km (0.25 mi) to the southwest. Lake Thompson is fed by the outlet (coming from the northwest) of several lakes: Rolt, Chevalier, Alida and an unidentified lake; as well as by the outlet (coming from the north) of Petit lac Thompson.

From Thompson Lake, the Thompson River descends on 13.7 km (8.5 mi), with a drop of 130 m (430 ft), according to the following segments:

  • 3.1 km (1.9 mi) towards the south-east (leaving the territory of Zec Lesueur) up to a bend of the river corresponding to a stream (coming from the west); then east to Lake Farina which the current crosses for 0.5 km (0.31 mi) south to its mouth;
  • 2.7 km (1.7 mi) south first, partially crossing Lake Farina (length: 0.8 km (0.50 mi); altitude: 263 m (863 ft));
  • 7.9 km (4.9 mi) (or 2.7 km (1.7 mi) in a direct line) towards the southwest by forming numerous coils, collecting the discharge of three small lakes and collecting the discharge of a small lake, to its mouth.[1]

Toponymy
