Maybe....I did a paddle a stretch upstream of Marion several years ago. Plenty of water. Put in was easy...take out was under bridge on 221. If you can get a copy of Benners book Carolina Whitewater it will probably give more details
Yes I've done it several times. In Marion you can put in just past Tom Johnson camping center on Old Greenlee Rd. There's a public access there. You could float to Lake James, but If you're going for smallies no need to go further then River breeze campground. All still water beyond there. This is a nice float for being so close to town. Not many people and you can often see deer. It will require a lot wading and yak dragging due to how shallow it is between the pools.
