Geography
The main neighboring watersheds of the Blanche river are:
 * north side: Beaudoin stream, Milieu stream, rivière du Pin, Gabriel River;

 * south side: Etchemin River;
 * west side: Dix stream, Bœuf River.

The Blanche river has its source in the Massif du Sud, in the Notre Dame Mountains, in the municipality of Saint-Luc-de-Bellechasse. This spring is located 10.4 km south of the center of the village of Saint-Philémon and 3.1 km south-east of the summit of mont du Midi.

From its source, the Blanche river flows in a forest zone over 10.5 km distributed according to the following segments:
 * 1.4 km towards the south in Saint-Philémon, to the municipal limit of Saint-Magloire;

The confluence of the Blanche river is located upstream of the confluence of the Bourget river and 4.8 km east of the center of the village of Saint-Luc-de-Bellechasse.
