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.
