The Blanche River (, , ) is a stream flowing in the municipalities of Saint-Ubalde, Saint-Thuribe, Saint-Alban and Saint-Casimir, in Portneuf RCM, Capitale-Nationale, Quebec, Canada.
The White River flows mainly in an agricultural environment, while passing near the villages of Saint-Ubalde and Saint-Casimir.
An undulating plain marks the region of Saint-Casimir (Quebec). This clayey plain is carved out by the Sainte-Anne River and its tributaries, including the Blanche River.
The Blanche River meanders towards the Sainte-Anne River. To the south, the hills are gneissic rocks (Clark and Globensky 1975: 10) belonging to the Laurentian highlands called the âÂÂPetite Laurentides of BatiscanâÂÂ.

On bridges, numbers are usually found on the bridge. (French)</blockquote>
The Blanche River watershed is located mainly in a forest environment, with the exception of the downstream section of the river, i.e. in a highly agricultural environment.
