I fish this area quite a bit. The Toccoa tailwater just outside of Blue Ridge, GA would be a good river for you to fish. A good access point if you are wading is the Curtis Switch boat ramp. There is a pretty good run below the ramp that is wadable when they aren't pushing water.The Hiwassee in Murphy is a warm water fishery.
If you want me specific info about the area contact me directly and I will be happy to share.
