Yamaska

Yamaska is the mouth of the Yamaska River on the south shore of the St Lawrence, where the river enters Lake Saint-Pierre after a course of 177 kilometres from the Eastern Townships. The name is traced to Abenaki words meaning where rushes grow, a reference to the marsh at the river mouth, the Baie de Lavallière. Champlain called the river Rivière de Gennes in 1609. When the seigneurie of Yamaska was granted to Michel Leneuf de La Vallière, the river was also called rivière des Savanes.
