Columbus and Tombigbee Waterways are not easy to get information on. There are not many maps available and they do not cover the backwater. The best is to select one in the area, and use the Corp maps also. They have the channel and the freebie that the USACE has lightly covers the backwater. There is little on a good map there. Google Maps will give you and Idea of the area. And the backwater can be treacherous in areas. BCB
