The "Rivière du Sud-Ouest" rises from various agricultural streams located around the hamlet Ménardville, west of the village of Farnham, northwest of the village of Sainte-Sabine, south of the village of Sainte-Brigide-d'Iberville, south of route 104 and south of Canadian National Railway section.[1]

From its head (draining a small area of marsh), the Southwest river flows 5.9 km north in agricultural area to the Canadian National railway; 3.0 km north to route 104 in the village of Sainte-Brigide-d'Iberville; 3.6 km north to Martel Creek; 2.4 km northeasterly to autoroute 10; and 3.5 km north-east to its mouth.[1]

The South-West river flows on the west bank of the Yamaska River in the municipality of Saint-Césaire. This mouth is 2.6 km upstream from the Saint-Césaire bridge over the Yamaska River (route 112) and 2.8 km downstream from the Autoroute 10 bridge.[1]
