## Geography

[edit]

The main neighboring watersheds of the Blanche river are:

* to the north: Old Mill Creek, Osgood River, Sunday River, Perry River;
* to the east: Bécancour River, rivière de l'Or, Prévost-Gilbert River;
* in the south: Bécancour River, Coleraine River;
* to the west: Bécancour River, Bagot River.

The Blanche River draws its source from a mountain stream located on the east side of Mont Saint-Adrien and west of downtown Thetford Mines.

The Blanche river flows on 8.2 kilometres (5.1 mi) towards the south, mainly in forest territory, according to the following segments:

* 2.0 kilometres (1.2 mi) south to the road;
* 3.7 kilometres (2.3 mi) southward, up to route 122 which it cuts to the southwest of the city of Thetford Mines;
* 2.5 kilometres (1.6 mi) towards the south, until its mouth.[1]

The Blanche River empties on the north shore of the Bécancour River, northeast of Black Lake, near an open pit mine.
