Marr's Perch Lake Lodge.
On the Seine river system. Excellent walleye, pike, perch, and smallmouth fishing. Sweet cabins, restaurant/bar. Boat docks are nice. Several nice lakes on this system all the way down to the dam. Lots of flooded timber too.
If you go, concentrate on the four corners area, banning lake, diversion, sunshine bridge, and I bay. In banning there is a little rocky island that just has one little tree growing out of it. Every pass netted us either an eye or a smallie.
If you want pike, go under the train tracks into little McCaulley lake. The pike are everywhere, but this lake has a lot of weeds and the pike are nice in there.
Good luck.
