Bernier River (Saint-Maurice River tributary)

The Bernier River is a tributary of the Saint-Maurice River, flowing on the north shore of the Saint Lawrence River, entirely in the municipality of Saint-Boniface, in the Maskinongé Regional County Municipality, in the administrative region of Mauricie, at Quebec, in Canada.

The course of the Bernier River generally descends to the southeast, in forest or agricultural areas. Its course passes between the village of Saint-Boniface and the city of Shawinigan.

The river surface is generally frozen from mid-December to the end of March. Safe traffic on the ice is generally from late December to early March. The water level of the river varies with the seasons and the precipitation.
