By no means an expert on rafting AK rivers. However, in the 70's I did raft the Tonsina River near Valdez. One piece of advice FWIW.
This river was a glacier river and loaded with sediment. Advice I was given was that since this was a glacier river loaded with sediment was that if you went overboard any pockets would collect sediment and if full enough drag you under. Because of this, I would recommend not wearing waders or hip boots in the raft. Rain gear and knee high boots would seem appropriate.
The Tonsina River was a whitewater river and I did get knocked off the raft because of a sweeper and miscommunication going around an island. Beware of the sweepers, they can be deadly. I was wearing regular hiking boots, heavy wool pants, and especially important, the best life preserver available at the time (a mae west). Obviously, I came out ok but that water was COLD. Fantastic trip, had a great time and saw about 30-40 Bald Eagles that day.
