The inlet is about in length from its head at the community of Rivers Inlet, which was a logging and fishing town that was also the home of the Wuikinuxv and their government, the Wuikinuxv Nation, also known variously as the Owekeeno, Awikenox, Oowekeeno and also as the Rivers Inlet people. The main rivers feeding Rivers Inlet are the Kilbella River and its tributary, the Chuckwalla River, and the Wannock River, which feeds the head of Rivers Inlet and was fed by the fresh-water fjord Owikeno Lake, in length, and which was fed by the Tzeo, Sheemahant and Machmell Rivers. The Machmell, the largest, was fed from the northern flank of the Ha-Iltzuk Icefield, one of the largest of the southern Coast Mountains icecaps, and which was capped by the Silverthrone Caldera.
