This is a good refernce for regualtions and there are also maps of all trout water in the state. The thing about Ga is that some of the water, is on private property. So you will have to beat the bushes a little to find water that is open to the public. That beiing said, most of the Major water ways designated as TW are fishable and have reasonable access. The Delayed Harvest areas are good and several of the guys on here can give you advice on directions and quality of fishing. Good luck and feel free to send a PM if you have other questions as well.
It is an excellent book. It gives great descriptions as well as directions to find trout streams. The things that he wrote regarding the streams that I am familiar with are right on point. He really seems to know what he's talking about. I'd reccommend the book to anyone.
