The Blanche River (in French: Rivière Blanche) flows in the administrative region of Chaudière-Appalaches, in the province of Quebec, in Canada, in the regional county municipality of:

  • MRC Bellechasse Regional County Municipality: municipalité of Saint-Philémon;
  • MRC Les Etchemins Regional County Municipality: municipalities of Saint-Magloire and Saint-Luc-de-Bellechasse.

The Blanche River is a tributary of the north shore of Etchemin River which flows toward north and empties on the shore into the St. Lawrence River, in front of Quebec.


The main neighboring watersheds of the Blanche river are:

The Blanche river has its source in the Massif du Sud, in the Notre Dame Mountains, in the municipality of Saint-Luc-de-Bellechasse. This spring is located 10.4 kilometres (6.5 mi) south of the center of the village of Saint-Philémon and 3.1 kilometres (1.9 mi) south-east of the summit of mont du Midi.

From its source, the Blanche river flows in a forest zone over 10.5 kilometres (6.5 mi) distributed according to the following segments:

  • 1.4 kilometres (0.87 mi) towards the south in Saint-Philémon, to the municipal limit of Saint-Magloire;
  • 0.6 kilometres (0.37 mi) towards the south, in Saint-Magloire;
  • 3.2 kilometres (2.0 mi) south, to the 12e-Rang road;
  • 3.8 kilometres (2.4 mi) towards the south-east, up to the 10th Rang;
  • 1.5 kilometres (0.93 mi) south-east, then south-west, to its confluence.

The Blanche river flows onto the north bank of the Etchemin River which here constitutes the municipal limit between Saint-Luc-de-Bellechasse and Sainte-Sabine. The confluence of the Blanche river is located upstream of the confluence of the Bourget river and 4.8 kilometres (3.0 mi) east of the center of the village of Saint-Luc-de-Bellechasse.


The toponym Rivière Blanche was formalized on 18 July 1973 at the Commission de toponymie du Québec. Before 1973, its official name was Rivière Etchemin Nord-Est although its current name was visible on some maps long before its officialization.
