Rivière Broadback is a magnificent wilderness river in northern Quebec, Canada, flowing approximately 450 kilometers (280 miles) through the boreal landscape of the Eeyou Istchee Baie-James region before emptying into Rupert Bay at the southern end of James Bay, near the Cree community of Waskaganish. Its watershed spans nearly 21,000 square kilometers of remote subarctic terrain. The Cree people, who have hunted and fished these waters for generations, call this river "Chistamiskau Sipi" (deep river) and "Matauchun Sipi" (river where water goes in different directions) — names that speak to its powerful and varied character. The river originates near Lake Trovlus, passes through Lake Quénomisca and the Evans area, and ultimately drains into James Bay. Formed following the retreat of the Tyrrell Sea during deglaciation, the Broadback is a geologically ancient waterway set in a landscape of low mountains, expansive boreal forest, and interconnected lakes. It is a true wilderness destination — little known and little traveled — offering anglers an extraordinary combination of remote solitude, dramatic whitewater, and exceptional fishing for walleye, northern pike, and sea-run brook trout.
