Lake Leatherwood would be a great choice! There is a trail that circles the lake and multiple places to fish along it. I would recommend fishing right from the dam though for crappie. Take some silver shineee hineees made by Arkie which can be bought at any local wal-mart or some minnows. Fish them 10' to 20' off the dam and you should catch some!
