Johnston Station at the US84 Bridge provides access to the Altamaha River, a major river system that drains nearly 14,000 square miles of southeastern Georgia. This is a significant waterway with an average flow of over 14,500 cubic feet per second and a moderate gradient of 0.6 feet per mile. The river maintains an average velocity of 3.45 feet per second, indicating a steady current that paddlers should respect. As a Stream Order 8 river, the Altamaha is substantially larger than most creeks and smaller rivers, making it suitable for various types of boating activities.
