Lake of the Woods in Coldwater, Michigan
They have a bunch of waleye in that lake right? I've thought about ice fishing there, iirc
This particular lake is pretty small, and while we've caught all kinds of bass, crappie and bluegills, I've never seen a walleye. There's a nearby lake called Coldwater Lake that's larger and might have larger variety of fish. Never been at the lake in winter though - my MIL's cottage isn't heated, so it's only used from spring to fall.
