I was hoping the "walk up from the lower take out" method Dave said would be available. Seems like it should since nothing I read said the actual river was closed - just the upper access, but haven't had the occasion to get out there yet and try it.
If it was available, I am pretty cool with doing the paddle upstream\walk upstream method. I end up finishing back at the car and normally have a walk back up the hill anyway.
If anything, this should mean some of those nice sandy beaches might be pretty deserted for all but us intrepid boaters.
