I found the following odd:
"If Watts is correct, the Water Witch would be just the third Civil War shipwreck — along with the ironclad CSS Georgia and the blockade runner CSS Nashville — to be found out of dozens known to have been sunk in Georgia waters, said Dave Crass, Georgia's state archaeologist."
I guess they aren't counting the CSS Jackson on the Chattahootchie.
