Hoh Bloackage/float info.

Hey guys so im heading to the coast on Monday. My question is as stated above. I will be floating from park-line down the first day and maybe 101 down later on in the week. I need to know if there is any blockages or obstacles that i should be aware of on the river? I know park-line down usually has some sweepers but i have never done this float so any info is greatly appreciated. Also what shuttles services are there now> I use to have Bob shuttle my boat but I'm not sure if hes still doing it. I will be floating by myself in my watermaster I am confident and proficient on the sticks but still learning. Again thanks ahead of time to any responses.
