It is said to be one of the largest river basins in the country, and as such, there are a lot of tributaries to this river.
According to legend, in the waters of the Altamaha, near the city of Darien, there is a strange creature. It appears ever so often and sightings of this creature go back to the times before whites settled the area. The Tama Indians from that area first told tales of a huge water serpent that hissed and bellowed. In the 1920s, timbermen who rode the river reported sighting something that fits the description of 'Altamaha-ha', also known as 'Altie'. Other sightings include a Boy Scout troop from the 1940s and two officials from the Reidsville State Prison from the 1950s."
