I would second lake despair for good walleye action.. but to get some good size fish you need to know where to fish..
the lake is a busy lake with anglers but very scenic with a couple mechanical boat portages you can end up boating in to 9 differnt big lakes.
it would be a good choice! as would all the others mentioned so far.. to many good places to choose from makes it hard.. kinda like pickin what deer stand to sit in on any given night!
good luck where ever ya go.. if ya go to lake despair my folks owned the resort next to bill and nells and i would be happy to point ya in the right direction on places to fish!
