Cisco to Moab is about 50 miles of mostly flatwater/small riffles with one additional river access point about 25 miles in. There are a few rapids that top out at III/III+ big water style wave trains at high water. It provides great desert scenery with very little if any river traffic. We did it at about 18G in 4 comfortable days. The camping is decent to good. With the snowpacks we've got right now in the state, I'd bet you could expect similar flows (15-30G) in the first half of May, but that's just speculating on what's ultimately a crapshoot. Wish I could give you details but it's been over 10 years. Lemme know if you have any questions, though, and I'll see what I can do anyways.
