I don't know about Wisconsin but in the U.P of Michigan their is the Sylvania Wilderness area, it is in Ottawa National Forest, its right on the Wisconsin / Michigan border it has 34 lakes, 21,000 acres and is canoe only, and has some great fishing for smallies their are special fishing reg's and it has gin clear water you can see 20' down. It was also protected before the lumber companies could get their hands on it, so it has some of the oldest trees in this part of the country.
   If you are interested you can email me and I'll give up a couple of my fishing hotspots and lakes.
