Possitive out of all of this

I live in Western Terrebonne and by no means am i excited about the current situation. With the BP Oil Spill Just Dinging a year a couple of weeks ago, wouldn't the increase flow of the river plus the flow through the Morganza Spillway be a good cleaning out of the Marshes of any remaining Oil. I know it kind of sounds dumb, but it is like Mother Nature is cleaning up a mess through a Natural event.
