Georgia has a reciprocal agreement with many of its neighboring states with regard to fishing inter-state waters. This means you won’t have to worry about straying into another state if you have your Georgia state fishing license on you. In other words, you'll be able to fish the waters along the borders with Alabama, Florida, North Carolina, and South Carolina. Keep in mind, however, that this doesn't cover all inter-state waters. For example, Georgia does have a reciprocal agreement with Florida regarding fishing licenses, but that only covers freshwater fishing near the border – St. Mary’s River and Lake Seminole, to be precise. If you're planning on fishing with a fishing license from another state, it's best that you check which exact waters you can fish with your local DNR. You should also familiarize yourself with the local size and bag limits before you drop your lines.
