Bk it very well could be done. And i only see two problems, scout time, and pulling everybody together on a minutes notice. The river gets high enough but it does not stay high enough very long. and theres thngs you and your team are going to have to talk about on the bank long before you ever get in a raft. First you need atleast ten people that you trust, and not just to get up and go fishing i mean TRUST!!!!!!!! With your lives.three of you in a boat and the rest at the most dangerous spots.I have alot of whitewater experiance, From big water to tech water. And the way i see it is that the stretch between deadline and painted rock is the water i would pay carefull attention to. There is a drop right before the corner leading in to painted rock that will be your toughest challenge. Stay in the middle and brace wth all you have. This is the first place that i would have two people set up with throw bags. Its not too bad of a swim but this is the one rapid that has a very big keeper hole. If the raft gets held you will be glad they are there. After that is saddle rock and three steps. You will hit the wall at the first drop in three steps but dont worry. Point your boat at the rock and hit it square, you will roll off the wall just fine. But dont waste any time geting turned back around. because now you have to hit the second drop and if you dont hit it square it wil flip you. This is where i would have two more people with throw bags to fish for people. you have alittle time before the next drop so if you do flip the throw bagers should be able to get you all but i would still have someone below the last drop fishing for people. Thats the brunt of the river if you get through that you are home free. kids take innertubes below that. As far as the rest of the safety make sure everybody knows the white water position. And your throw bager know how to work a throw bag and how to use there butts for mechanical advantage.The rest is the comunication in the boat the person rowing has the most experiance and is the person calling the shots period. The two paddle assists must listen even if they think you are wrong. They need to be able to just hear a comand and do it. Because making it down depends on it. Good luck and take your time preparing.

P.S. If you do flip try to get everybody back on the boat its alot easier for saftey to hit the boat with a throw bag than a single person floating in the water. And besides the boat is the bigest life preserver you have
