Above the confluence of the spring Branch you'll catch a few rainbows (very few but there are some), Smallies, and Goggleye.
Below the spring branch there are rainbows, browns, smallmouth, and Goggleye. And you just have to put in some time to learn which areas are holding them. The recent stockers are almost always in a tight school tucked into a small area the size of your dinner table and once you find one you can repeat that drift and catch a limit real quick. The browns, and the rainbows that have been there awhile act more like trout are supposed to act, and you just have to work for them.
Bennett to Barclay is a nice float, and about the only one to consider due to the shuttle difficulties of the Niangua.
