The "Inconnue River" is a tributary of the east bank of the rivière des Perdrix, which flows towards the south bank of the Bras Saint-Nicolas; from there, the current flows to the southeast shore of the rivière du Sud (Montmagny); the latter flows north-east to the south shore of the St. Lawrence River.[1]

The Inconnue River has its source on the north slope of the Notre Dame Mountains, in the township of Bourdages, in the municipality of Cap-Saint-Ignace. Several branches of mountain and forest streams feed the head of the Inconnue River.[1]
From its source, the Inconnue River flows through mountainous and forested areas over 5.9 kilometres (3.7 mi), divided into the following segments:
- 3.1 kilometres (1.9 mi) southwesterly in Cap-Saint-Ignace, to the limit between Cap-Saint-Ignace and Notre-Dame-du-Rosaire;
- 2.8 kilometres (1.7 mi) north-west in Notre-Dame-du-Rosaire, until its confluence.[1]
The Inconnue River flows on the east bank of the Perdrix River (Bras Saint-Nicolas) in a small valley north of the Érables mountain. This confluence is located 14.3 kilometres (8.9 mi) from the south shore of the St. Lawrence River, 8.4 kilometres (5.2 mi) north of the village of Notre-Dame-du-Rosaire and at 15.8 kilometres (9.8 mi) southeast of the Montmagny highway bridge.[1]
