http://www.mvr.usace.army.mil/NavCharts/UMRNavCharts.asp Is about the best you can find, no depths, and it marks the wing dams, you’re best advised to keep you eyes open for them, you can basically see most of them, just look for a ridge of water and the wing dam is usually right in the area, usually a bit upstream of the wave a bit. Be careful out there depending on your boat and water level (which is currently down a bit) you may or may not be able to float over them, and that of course depends dam to dam too. There does seem to be a couple wing dams marker with very little bouys, but don’t count on it. Good luck, and be sure to post some results if you do head out there
