Rivière Blanche is a stream located in Quebec, Canada, flowing through a region rich in both natural beauty and angling opportunity. The river is part of the broader Zec de la Rivière-Blanche territory, a controlled harvesting zone (ZEC) of 729 km² situated on the eastern slope of the Batiscan River valley and the northern slope of the rivière à Pierre, within the Portneuf Regional County Municipality in the Capitale-Nationale administrative region. The ZEC was incorporated in 1978 following the abolition of private hunting and fishing clubs on public lands, and today it is managed by L'Association sportive Miguick, Inc. (ASM). The Blanche River's headwaters originate at Lac-Blanc, and the river is one of five rivers within the ZEC territory, all of which are open to sport fishing. The surrounding landscape is characterized by boreal forest, and the highest peak within the ZEC reaches 426 m (1,398 ft) at Mount View.
