Yep. There is never any water in the Ark early in May, it will be a rocky low water float. Probably your best bet for that early in the season on the Ark will be the Royal Gorge, but that's still really a class III trip with a couple class IV rapids at low water.
It's pretty much the opposite corner of the state, but the Upper Animas outside of Durango has a better chance of having water and it is a serious full day class IV run with a couple class V rapids.
