Vallée River

The Vallée River (in French: rivière Vallée) is a tributary of the west bank of the Chaudière River which flows northward to empty onto the south bank of the St. Lawrence River. It flows in the municipalities of Saint-Elzéar and Siante-Marie-de-Beauce, in the La Nouvelle-Beauce Regional County Municipality, in the administrative region of Chaudière-Appalaches, in Quebec, in Canada.

The main neighboring watersheds of the Vallée river are:
 * north side: rivière des Îles Brûlées, Chaudière River;
 * east side: Chaudière River, Saint-Elzéar stream;
 * south side: Aulnaies stream, Savoie River;

The Vallée river has its source in a mountainous area, in the municipality of Saint-Elzéar. This head area is located 2.5 km west of the center of the village of Saint-Elzéar, at 6.0 km west of Chaudière River and 8.0 km northeast of Mont-Sainte-Marguerite.

From its source, the Vallée River flows over 9.8 km in agricultural and forest areas, divided into the following segments:
 * 1.5 km north, in Saint-Elzéar, to a country road;
