Rivière Assinica is a remote wilderness river flowing westward through the Nord-du-Québec region of Quebec, Canada, within the Eeyou Istchee Baie-James municipality. Stretching approximately 59.2 kilometers (36.8 miles) in length, the river originates from a cluster of lakes — including Assinica, Comencho, Waposite, Cachisca, and Opataca — and serves as a tributary of the Broadback River, which ultimately drains into Rupert Bay south of James Bay. The river descends from an elevation of roughly 359 meters (1,178 feet) at its headwaters near Assinica Lake to approximately 291 meters (955 feet) at its confluence with the Broadback River. This is true boreal wilderness fishing, set within a landscape dominated by the forestry and outdoor tourism industries, offering anglers a genuinely remote and unspoiled experience in the Canadian north.

The confluence of Rivière Assinica with the Broadback River is a natural focal point for anglers, as these junction areas concentrate fish in northern river systems. The source lake chain — particularly Assinica Lake and the connected lakes of Waposite and Opataca — represents productive stillwater fishing adjacent to the river system. The transition zones between the lakes and the flowing river sections are also worth targeting.
