The best fishing tends to be in spring and early summer. You can take nice catches of largemouth bass and walleye in the shallow areas. There also is a nice muskie and northern pike population, and you can take bluegill, white bass and crappie there throughout the year. He rates Lake Marie as being the best for bass. It can be tough fishing for bass, because there are a lot of shad, but some real nice fish are taken there each year.
Shad also attract walleye and muskie.
Most walleye are taken by trolling. You'll also find some northern pike in these same spots. Most of these areas can be located on maps. I'd rate crappie and white bass fishing as fair. Gadzinowski gives a thumbs up on Catherine and Channel Lakes for both walleye and muskie.
