From the greater Wichita area it is about 2hrs to find any really good bass fishing lakes. Bluecat, Flathead, Crappie, Walleye, Saugeye, Whitebass, and Wiper can all be found much closer. Many guys around here have access to great watersheds and sandpits, and catch large numbers of quality fish.
IMO the closest lake that produces quality bass to this area is Butler Co. Lake and it is very small.
