Me and my boys have done quite well on Flatheads down on Table Rock Lake. Bluegill and Green Sunfish are very easy to come by. A little hook and a small piece of worm around any bank area should get you some quick and easy bait. This spring we set out trotlines for 5 or 6 days and caught lots of Flatheads under 10 pounds. One 21 pounds, and one 50 pounder. All these were caught out of Aunt Creek State Park which is close to where you will be. However I've ran lines a couple times on other areas of Tablerock and caught them just as well. As you already know, the bigger the bait, the better. We had 2 pound Flathead eat huge Green Sunfish on 9/0 hooks. Good luck and let us know how you do!
