Rivière Pikauba is a wild and remote waterway winding through the heart of Quebec's Laurentides Wildlife Reserve in the Saguenay–Lac-Saint-Jean region. Originating from Pikauba Lake in the unorganized territory of Lac-Pikauba, the river follows a complex course of approximately 118 kilometers, beginning with southward segments before turning northwest through deep forested valleys and ultimately flowing north into Lake Kénogami, a few kilometers southwest of the Jonquière borough in the City of Saguenay. The river forms part of the 3,390 km² watershed of Lake Kénogami, which drains into the Saguenay River and eventually reaches the St. Lawrence estuary at Tadoussac. This is genuine Quebec wilderness — dense boreal forest, dramatic valley terrain, and clear, cold water that defines classic brook trout habitat.
