Never been here. What type of bait should I use for fishing? Is license required?, and Is there a fee or charge to fish there?

Yes you need a fishing license, plus extra to catch trout per person, not corn or dog food, you will be fine heavily...no more then 7 fish at a time and not smaller than 7 in.

Where you get a fishing license and k you need

Need a freshwater license to fish, and a trout license on top of that to catch trout. You can use any bait here, live or artificial. You can only use artificial north of Medlock Bridge. Trout limit is 8 per person, per day, no size limit at this particular location. Sourced on Georgia Department of Natural Resources.
