Blanche River (Montmorency River tributary)


The Rivière Blanche is a tributary of the east bank of the Montmorency River. It flows in the unorganized territory of Lac-Jacques-Cartier, in the La Côte-de-Beaupré Regional County Municipality, in the administrative region of Capitale-Nationale, in the province of Quebec, in Canada.
This valley is served by two secondary forest roads going up each side of the course of the river; a third forest road serves the upper part. Forestry is the main economic activity in this valley; second, recreational tourism.
Because of its altitude, the surface of the upper part of the Blanche River is generally frozen from the end of November to the beginning of April; however, safe circulation on the ice is generally done from mid-December to the end of March. The lower part of the river course has a freezing period of about a week less than the upper part. The water level of the river varies with the seasons and the precipitation; the spring flood occurs in March or April.
