I have used a jig with a minnow or a single hook with a minnow. In Hillman, they have the minnows that they call "blues" and they always worked well. Yes, you can catch them in 10 feet of water, more so in the daytime as they come up looking for minnows along the shore etc, but I always fished for them in deeper water for the bigger splake. Don't overlook Avalon Lake, between Atlanta and Hillman either... it is loaded with Splake just like Clear lake and some native lake trout.
I have fished for them many times. I always seemed to do well for them at dusk and even after dark up to 7 pm or so. If you have a flasher, try fishing in deep water after dark and about 10 feet off the bottom. I have had a friend who has scuba dived Clear Lake and he was surprised by the giant crappie in Clear Lake. Good Luck....
