Le Petit Bras (Amédée River tributary)

The Petit Bras rises from a small lake (length: 0.3 km (0.19 mi); altitude: 187 m (614 ft)). This lake is located at:

• 2.7 km (1.7 mi) west of Castelnau Lake;
• 4.5 km (2.8 mi) west of lac à la Chasse (Baie-Comeau);
• 7.1 km (4.4 mi) north-west of the mouth of Le Petit Bras.

Le Petit Bras flows on 11.8 km (7.3 mi) with a drop of 137 m (449 ft), according to the following segments:

• 0.7 km (0.43 mi) first towards the south, then towards the northwest where it intersects the route 389, up to a bend of the river corresponding to a stream (coming from the northwest);
• 4.8 km (3.0 mi) first forming a hook towards the south, then towards the south-east by collecting a stream (coming from the south) and three streams (coming from the north) to a bend in the river where the current turns east, crossing a marsh area before flowing south into Petit Bras Lake;
• 2.1 km (1.3 mi) towards the south by crossing on 1.6 km (0.99 mi) the lake Petit Bras (altitude: 69 m (226 ft)) over its full length; then crossing a small lake on 0.4 km (0.25 mi) where the current turns south, to its mouth;
• 1.4 km (0.87 mi) south-west passing from the west side of the Jean-Noël-Tessier industrial park, to a stream (coming from the north-west);
• 2.8 km (1.7 mi) to the southeast by crossing route 138 to a bend in the river where the current turns southwest, until its mouthpiece.[2]

The Petit Bras flows on the northeast bank of the Amédée River, that is to say:

• 5.4 km (3.4 mi) north-east of the mouth of the Manicouagan River;
• 1.9 km (1.2 mi) north-west of the mouth of the Amédée River.[2]

The toponym "Le Petit Bras" was formalized on August 2, 1974, at the Place Names Bank of the Commission de toponymie du Québec.[3]
