Geography

The main neighboring watersheds of Bras Saint-Nicolas are:

The Bras Saint-Nicolas has its source at the confluence of the Méchant Pouce River and Fortin stream, in the municipality of Sainte-Apolline-de-Patton. This spring is located on the west side of the hamlet "L'Espérance", on the north slope of the Notre Dame Mountains.

From its source, the Bras Saint-Nicolas flows over 45.5 kilometres (28.3 mi), divided into the following segments:

Upper course of the river

Lower course of the river

  • 4.3 kilometres (2.7 mi) west, to a road;
  • 2.1 kilometres (1.3 mi) southwesterly in Saint-Eugène, to the municipal limit of Cap-Saint-Ignace;
  • 2.0 kilometres (1.2 mi) southwesterly in Cap-Saint-Ignace, to the highway 20 bridge;
  • 1.7 kilometres (1.1 mi) west, up to the bridge;
  • 2.2 kilometres (1.4 mi) towards the southwest, passing south of the village of Cap-Saint-Ignace, to the road;
  • 3.7 kilometres (2.3 mi) southwesterly, along highway 20, to a road bridge;
  • 3.0 kilometres (1.9 mi) southwesterly in Cap-Saint-Ignace, to the municipal limit of Montmagny;
  • 4.9 kilometres (3.0 mi) towards the south-west, collecting the waters of the rivière des Perdrix (coming from the south-east), then towards the northwest to its confluence.

The Bras Saint-Nicolas empties onto the south-eastern bank of the rivière du Sud (Montmagny). This confluence is located upstream from the route 132 bridge, downstream from the route 283 bridge, in the heart of the village of Montmagny.

Toponymy

In a lower segment, parallel to the St. Lawrence River, the Bras Saint-Nicolas meanders at an altitude of about fifteen meters, crossing a stronghold granted in 1672 to Nicolas Gamache by the intendant Jean Talon. A first hypothesis associates the origin of the toponym "Bras Saint-Nicolas" with this pioneer. Another hypothesis is rather referred to other to Nicolas Després, father of Geneviève Després whose husband, Louis Couillard de Lespinay, had bought the seigneury of Rivière-du-Sud in 1654 and 1655.

In 1802, the toponym “R. St. Nicholas' appears on a map by surveyor Samuel Holland. In 1803, the toponym appeared on a map of Vondenvelden with the generic Bras. In 1815, Joseph Bouchette also identified it by the same generic, a term used to designate a tributary or a subdivision of a watercourse.[1]

The toponym "Bras Saint-Nicolas" was made official on December 5, 1968 at the Commission de toponymie du Québec.[2]
