Try Minnetonka. I fish over by the Wayzeta (sp?) Marina alot. In the spring when the weeds are just starting to green the carp congregate under the lights on the docks. Go there on a calm starry weeknight and it can be insane. I've got 'em up to 20lbs, but I've seen bigger that wouldn't bite. The most fish I've seen there at one time is about 100, and they're all pretty decent. We even get some bass, muskie, pike, eyes, gills, and craps coming by too.
