Le Bras (Ferrée River tributary)

The Le Bras (in English: The Arm River) flows through the municipalities of La Pocatière (MRC of Kamouraska Regional County Municipality) and Saint-Roch-des-Aulnaies (MRC of L'Islet Regional County Municipality), in the administrative regions of Bas-Saint-Laurent and Chaudière-Appalaches, at Quebec, in Canada.

The Le Bras River is a tributary of the east bank of the Ferrée River, which flows 240 m further north on the south shore of the St. Lawrence River. This last confluence is located in the small hamlet of Village-des-Aulnaies, located southwest of the village of La Pocatière and northeast of the village of Saint-Roch-des-Aulnaies.

Geography
The Le Bras river has its source at Bourgelas lake (length: 0.8 km; altitude: 197 m) located in La Pocatière. This lake is located 6.0 km southeast of the south shore of the St. Lawrence River, 7.1 km southwest of the village center from Saint-Onésime-d'Ixworth, at 5.3 km south of the center of the village of La Pocatière and at 12.2 km at the east of the village center of Saint-Roch-des-Aulnaies. This lake is located near the limit of the municipality of Saint-Onésime-d'Ixworth. Its mouth is located to the north-west.

From this lake, the Le Bras river flows in a forest and agricultural zone over 14.6 km, divided into the following segments:
 * 2.0 km towards the southwest in La Pocatière in a forest zone, crossing Lac Perdu (length: 160 m; altitude: 168 m) to its mouth. This lake is located in a small valley on the east side of Montagne des Marais and on the north side of Coteau Pelé, near the limit of Saint-Roch-des-Aulnaies;
