I would suggest trying to reserve a spot on First Island. think it's arguably the best island to camp on, although all are pretty good. There are grass beds directly in front of it (south). I have camped here several times and caught fish both times from the bank. A better suggestion would be to fish at night and at first light from a boat just to the south of the "c" shaped cove. A Tennessee license will be necessary for this area and the closest marina is Holly Creek. I think this is your best bet.
