Opemisca

Lake Opémisca is a long widening of the Chibougamau River, whose waters continue west through the Waswanipi and Nottaway towards James Bay. Cree families have long hunted in the country around Opémisca and Lake Chibougamau. Between 1815 and 1822, the Hudson's Bay Company kept the Rush Lake trading post at nearby Lake Chevrillon, another widening of the Chibougamau. The name Opémisca has also been written Opamiska.
