The easiest way to remove that bedlam sediment, as has been demonstrated on the Fraser, Kennedy Creek, and S Paririe Creek, is to flood the watershed with pink and chum. The amount of sediment that spawning salmon transport downstream is tremendous. Obviously, we are having issues with excessive pink and chum in N Pacific (thanks to the AK hatchery programs) but if sediment is such an issue, let the fish move it out. If Chinook are that important, stop killing the pink and chum.
