[1] Apart from the passage of the river in a small hamlet of Pont-Rouge (near Lake André), the Blanche river flows especially at the border between the agricultural and forest environment, the main economic activities of this small valley.

[2] The surface of the Blanche River (except the rapids areas) is generally frozen from the beginning of December to the end of March; however, safe circulation on the ice is generally from late December to early March.

The water level of the river varies with the seasons and the precipitation; the spring flood occurs in March or April.

The Blanche River rises at Lac Blanc located in the northwestern part of the municipality of Sainte-Catherine-de-la-Jacques-Cartier.

[3] The toponym "Rivière Blanche" was formalized on December 5, 1968, at the Place Names Bank of the Commission de toponymie du Québec.
