Altamaha-Ha is the name of the lake monster that inhabits the Altamaha River, tributaries, and marshes near Darien, Georgia. The monster is somewhat eel-like in appearance. Because the Altamaha-Ha lives in a river it is not technically a "lake monster". It is from 10 to 40 feet in length, and 1 to 2 feet in width. It has been reported since at least the early 1960s. It has been sighted many times, frequently varying in length but fairly consistent in shape. This may suggest multiple creatures.
