I use to fish the heck out of Lake sinclair that's a little south of you. I never did any good with plastic worms or such once the water got cold. I mostly used cranked baits and spinner baits and I moved them pretty slow. When the weather was really bad, I'd get my big ol balso b in white and I'd fish it around the banks in coves that were near deep water. I caught some really nice bass that way. A friend of mine use to catch a lot of spotted bass on Lanier in the winter time. He would locate schools of bass on channels and drop offs down to 60 foot deep and then he would drop a silver spoon down on top of them and jig it up and down off the bottom. When you do this, the fish don't really hit it, they just take it in their mouths as if falls, so you have to pay alot of attention to your line. If the line stops moving before it gets to the bottom, set the hook. You also have to keep the line tight enough to where you can feel the spoon flutter as it falls, if it stops fluttering jack some jaws.
