How about Lake Mendota, Lake Monona, Lake Waubesa, Yahara River, Lake Wisconsin, Wisconsin River...
Just kidding.
I'm not really familiar with that part of AR, but the Arkansas River and Lake Dardenale is close by to you. Not sure if they have any walleyes. Dardenale should have some nice bass in it although I've never fished it, just heard from BASS magazine. Bull Shoals Lake has walleye, but I don't fish it either. The Buffalo River should start picking up soon for smallies.
