Chuck,
We fished the Elk a few weeks ago and floated from the dam to Ferris Creek Bridge. You can wade at Farris Creek and the dam, as well as Van Zant Bend (which I believe is still public access). Take some midges and if you don't have any midges, take some midges. A BHPT will also do the trick, but I would think about taking some midge patterns ;^}.
Also, we camped at Tims Ford State Park, which was clean and camper friendly. We had a great weekend and I am sure you will too. Let us know how you do.
