Altamaha River, GA

Looking for information on the Altamaha River. Planning a @75-mi trip from Lumber City to Jesup (tentatively) in mid-March. Water levels? Difficulty? Camping spots along the way? Contacts who might have info? I’d appreciate any information you have. Thanks!

Also, google earth often is detailed
enough that you can pre-scout some campsite options. River has been relatively low lately, leaving more sandbars, but we often get a lot of rain in Feb. and March.
