Until recently I had no idea that the Colorado River just past the mouth of the Dirty Devil was hundreds of feet northwest and 140 feet higher than the historic river location/elevation before Powell reservoir and the "Dominy Formation" of silt. Could a Pearce Ferry style rapid appear upriver from the North Wash "ramp"?
The Dirty Devil drains about 4,300 square miles, could a large rain/melt event force debris out of the mouth steering the Colorado towards its historic channel leaving North Wash high and dry like Hite's boat ramp?
I don't know the answers, but the good folks over at Returning Rapids of Cataract Canyon
have been presenting some facts, they recently released a presentation based on this area and the interesting changes wrought by the reservoir and resulting sediment. It's worth a read and my opinion is that this volunteer effort could use our support. (I'm not affiliated though I may donate/volunteer.)
I have only been to the North Wash boat ramp on a river trip twice, including last year when it was in great shape after grading and very usable three years ago. If I manage to hitch a ride again this spring, I know that everybody on that trip will be prepared to go all the way to Bullfrog because some rigs are too big to carry if North Wash is a mess.
The Returning Rapids effort has been brought up before on this site last summer but that was before their website and excellent trip reports:
If you have about an hour to burn this presentation is very interesting and well done. https://www.youtube.com/watch?v=5lFfUbEuj6Q On a side note if you are doing a fall Cat trip I've never been and would be interested in joining up with a group with a motor. Have equipment, boat, truck...
