Sunken Drift Boat
Did you see a partially (or fully) sunken drift boat at the runout below lower Disaster Falls? It belongs to a family friend of mine who ran it with me two weeks ago when the Green was around 4600. He had flotation compartments in the bow and stern, but after flipping in the big water in Lower Disaster, it wasn't upside-down-floating very well and pinned on a near-surface rock in the class II below and the river flowed over the top. The front of the boat went over the rock and the back caught and the boat settled over the rock, so it was basically upside down with the rock right in the middle of the boat, and was 95% submerged. There wasn't anything we could do with it at that level. At that level, you could have passed it in a raft without noticing it was anything but a rock if you didn't look closely. It seemed like at least one of the compartments hadn't maintained airtightness because it really wasn't floating much before it went down. With the big spike in flows last week I assume the wreck either dislodged and "floated" downstream until the next pin or echo park, or is just totally under water and won't be retrievable until much lower flows.
It was definitely a tough and expensive learning experience for my friend--that boat was definitely not qualified for a high water Dolores trip. I wouldn't want to be rowing anything less than a Grand Canyon Dory at those levels, as far as hard boats go. We had a big enough group that it didn't totally ruin the trip, the food and critical gear was on rafts. He did lose a pricey boat and a nice partner stove, though (at least for now).
