Much of the surface water in southern MO has a gray, milky look. My guess is that it's caused by the limestone that is present throughout much of this State.
Bullheads can be easily caught by fishing with worms on the bottom. But other fish will take the bait too. You could throw out a handline and check it periodically to see how you've done. No need to stay with it, especially if you're catching only BH or nearly all BH. It's a simple thing to try.
