Beware
Wappapello is a lower end eater. BIG TIME. Stay in the boat lanes (River channel). If you have never been there before get a map before hand and read it.
Wappapello was built as a flood control lake, they flooded swamp forest of Cypress trees. Before they flooded it the cut down the cypress trees and the stumps are still there (JUST UNDER the Water Line) 60 years later. Being Cypress they will for the next 60 years also.
good map of the lake
