I don't know how far you're willing to travel. There's a Martha's Quarry I've heard of in Tennessee, somewhere outside Nashville, and of course Pennyroyal Blue Springs in Hopkinsville, a town in southwestern KY. I don't know that I'd want to drive all that way to dive them, but then again, if you wanted to take a long weekend and knock out a few quarry dives over 2 or 3 days, well, that's an option. Tennessee has a Dale Hollow Lake some dive, but I don't think it's near you.
I don't know that much about the diving in Arkansas, but perhaps some of the locations there might be of interest.
