My understanding is the Lake Allatoona is mostly just stocked with bass, and tons of crappie.

Crappie usually travel in schools, so you can catch several at a time. They like hanging around logs, boat docks, etc.

Minnows are their favorite and small artificials that imitate minnows work well too. Fish for crappies with lightweight 2 to 4 pound line with light spinning tackle.
