Addison's Scale, Gear List, Owyhee River

I've been done with my Owyhee trip for a week now. Since starting work on the Oregon Desert Trail late last year it's been my goal to hike/packraft the entire 750 miles. This Owyhee chunk has me up to 425 miles, and I'll complete the trail in September with the section between Bend and Plush, Oregon.

For a packraft alternate in the Owyhee canyon, I'll be putting together specifics on which sections are suitable at low water to paddle; from 3 Forks to the area just after Iron Point I would recommend paddlers be comfortable scouting and running low flow to at least Class III. From Five Bar to 3 Forks and from Iron Point on I think less experienced paddlers would be fine (200 cfs and less). Stay tuned for more details.

All this rating of rapids in a remote canyon however is a bit of a faulty science. After talking with Kirk at length about what a Class III looks like road-side, compared to a Class III in a canyon days away from civilization, it seems like there could be a better rating system. Not all rapids are equal depending on your surroundings. 

He shared this video with me about Addison's scale that separates rapids or rivers into ratings based on the difficulty, danger, and exposure. Based on this rating boaters can get a much better picture of the true risk involved in a rapid or river.

For example, with the trip I just completed at low flow on the Owyhee, there wasn't too much difficulty in the rapids, definitely some maneuvering and scouting, so I'd rate it a difficulty of Class III. The danger - risk of injury or death, was also in the realms of 3, however I think some of the portages may have been 4, getting around The Ledge, Half Mile, and Widowmaker involved some serious rock scrambling, lifting and lowering of the boat, climbing...even being very careful I slipped and cracked my tailbone good on one portage. Risk can be high, so I'm inclined to go with a 4. As for exposure, you are far far away from help on the Owyhee. If I had to hike out it would be days to help. I had a Delorum Inreach beacon, so that could have brought help to me, but that could take at least a day as well. So for exposure I would give the Owyhee a C rating. So for the Owyhee at low flow I give it a Class III-4-C rating.


Now for my gear list. I definitely had some extras that I should have brought, but 4 pairs of socks??? Don't know how that happened. I brought 2 throw bags, but didn't need 2. So below is mostly what I brought, but leaving off the extraneous things that I regretted bringing.
