I bet if you stay above the washout you would be fine. The area below the wave is pretty shallow (sub 4") but if you stayed above, or not too far below the wave you would be fine.
The think a bigger concern would be with launching. Im not sure if the NCC allows motorized craft between Deschenes Rapids and Eddy Damn. I think the devil lies in finding a spot to launch as NCC land covers the entire area.
