Dirty Devil from Hanksville to Powell gets run a fair amount, I wouldnt say "regularly" but it does see its share of traffic.
its class II all the way, the toughest part is getting good flows.
in the bios section of WSR there is a pic of one Utah boater, Im sorry I dont remember which one, his picture is a self shot he took on a solo mission down that a couple years ago when it flooded at 15,000 or something.
Im duckie'n down Muddy and Im bringing my pops too, who doesnt boat much, so it should be a good time
