Perch, crappie, sunfish, walleye, pike, bass, trout (on the great lakes.). You can catch them from the bottom of the state to the top. Coming from Ohio Petenwell and Castle Rock is in the lower middle portion of the state right off the interstate, or you could hug the coast and try Winnebago and the Green Bay area. Too many lakes to list way up north, or stay on I-90 and fish the Mississippi.
