I came off Cat 8 days ago, we got 7mph all the way from Waterhole camp to the takeout (6hp motor, four rafts).
Current was good, takeout was an SOB. Muddy, I would consider some portage boards left in your rig for the take out. We got it as the water was coming up a bit and it was a muddy steep bank to the gravel. One guy took his pants off and shuttled gear across the worst of the mud, took us 2.5hrs to derig and carry our stuff up to the trailers.
