In its journey south, the river veers to the southwest to flow over (measured by water) in Saint-Jean-Baptiste where it enters the village. The river then passes between the Mont Rougemont and Mont Saint-Hilaire it bypasses remotely. Then runs almost straight up to the limit of Saint-Mathias-sur-Richelieu, close to the northern part of the former territory of Sainte-Marie-de-Monnoir (merged to Marieville in 2001). Hence, this small river cut Saint-Mathias-sur-Richelieu, diagonally across by water) to enter the Richelieu River, south of the village of Saint-Mathias-sur-Richelieu and north of the city of Richelieu.
