Hey BRC, I hunt out that way myself and intern with the TWRA agents in charge of Oak Ridge WMA. The only days you are allowed on land is during early goose season on a few select weekends. You can however throw on some waders and stand on the bank. Iffen you want to meet up and go for a hunt sometime let me know. I've got an area I'm planning on giving a try on Monday. Haven't been there, but it looks like a great spot. Let me know what you wanna do.
As for TVA land you can do whatever you want. I hunt some TVA land there and you can setup right on the bank.
We can hook up next year for the first weekend of the goose hunt. After that they all head for the parks. I tried hunting them the second weekend and came up empty handed. After that we can hit it up for early woodie season. Me and my buddy saw a ton of woodies and I'll need a new hunting partner as he's going in the Navy in June, and my brother is usually busy with JROTC on the weekends. If you're down this way tomorrow evening I'll be in the archery department at Gander Mountain (I could also be in firearms or fishing too, just hit the orange button on the archery counter and I'll head over). If not I work sunday from 10-7. We'll get something going if you want.
