Geography


The Blanche River flows northward mainly in agricultural (or forest, in places) territory on the south shore of the St. Lawrence River.[1]

A marshy area (2.3 kilometres (1.4 mi) by 1.7 kilometres (1.1 mi)) straddling the limit of the municipalities of Sainte-Eulalie and Daveluyville (Defoy sector) constitutes the head of the waters of this river. This area is located in the Rang des Épinettes; it is drained by the Paquin stream (to the north), by the Vigneault stream (to the south) and the Béland stream (to the east). This area is located northeast of Saint-Samuel-de-Horton, southwest of Daveluyville, east of Sainte-Eulalie and south of autoroute 20.[1]

The course of the Blanche river descends on 51.1 kilometres (31.8 mi), with a drop of 67 metres (220 ft), according to the following segments:
