Lake Wahtopanah
Also known as the Rivers Reservoir, Lake Wahtopanah is a reservoir on the Little Saskatchewan River just east of Rivers. Provincial surveys list walleye, northern pike, rock bass and perch as the common species, and index netting found walleye the dominant catch. It has produced Master Angler walleye and pike, hosts an annual summer fishing derby, and offers boat launches plus camping at Rivers Provincial Park.
