Why the concern for sleeping in a tent in spring? I ask because I am planning a multi-day fishing trip to the West Fork of the Chattooga soon. That's a bit downhill from you, but still in the same general region.
In NC if property is privately owned it can be stocked. I think you might have to get a permit to do so. Hatchery must be certified meaning the fish are healthy and parasite free. No clue on how it is in Georgia.
Ended up wet wading last two days of the trip. Fishing was
typical for the Park in April. Caught several each day and all
under 10"s. The biggest was caught on a Beaded Zebra midge.
No stand out nymph. I spent more time following behind my
Son than fishing. His skills are a little rusty after living in
San Diego for the last 6 years. We had a great trip)).
