I took a canoe down the Dirty Devil six or seven years ago. I wish I could remember the flows, but can't. We put in at Poison Spider Wash (or something similar?) as to avoid the not-so-canyonesque sections, somewhere downriver of Hanksville, pretty rough rough road, but did it in a Subaru. flows couldn't have been that good, because I DO remember getting out of the boat occasionally and pulling over sandbanks. HUGE cutbanks as you get closer to Powell, watchout, but no "rapids" to speak of...back then at least. yes, good camping and hiking.
