The best walleye fishing in the US and Canada! There’s no question about the Missouri River being a great walleye fishery. There are lots of deep and shallow gravel pits and sunken islands throughout the entire river system. I believe there are many great walleye waters in the US and Canada, but by far there is no other area than the Missouri River near Chamberlain that will compare with the numbers of 1 to 3 pound class walleye that are caught each year. There is also the possibility of an 8 or 9 pound walleye to be caught, both on Lake Francis Case and Lake Sharpe. Lake Francis Case and Lake Sharpe are high quality walleye lakes managed by the South Dakota Department of Game, Fish, and Parks.
