From Palisade to Loma is a great run and at the confluence of the Gunnison River is a wave to surf when the waters up, there's another wave that kayakers surf, that's at 23 road. You need to live there or have some one tell you when those waves are goin off. A real neat sup would be Ruby Horsethief on the Colorado R. from Loma CO to Westwater UT(there is a ranger at the Loma launch that checks for portable toilets(a subject for a later discussion). Ruby Horsethief is 26 miles and has a challenging rapid at Black Rocks(class 2+ at times). The Palisade run through GJ has a hole you wouldn't want to get caught in(it's location is just down stream from the new expressway bridge, around 27.5 rd but can be avoided in the fast moving water on the left)(also the Gunnison River waves can be avoided on the right). I've done all of these runs either by canoe or kayak and I can't wait to get back and do these on sup. Another one is Whitewater, CO to GJ on the Gunnison R.

The Loma to Westwater is a great paddle. Steve "Hammie" Hamilton and I did it last July running at 5000cfs +. We started before 6:00 A.M. and avoided the dreadful afternoon winds which I encountered the second time by leaving at 10:00 A.M.
It takes about 5 hours, if you're in good condition, 6+ hours with a lunch break and not "pushing". Black Rocks does gets narly, but when in doubt, get on your knees, sit, or straddle the board for that short portion. If you paddle it in one day, neither a fire pan or toilet is an issue. Can't wait to do it again when I return from Florida in May. Doing about 5 races down here.
My other favorite paddle is Potash, UT. (near Moab), to the confluence of the Co. R. and Green R. A 3 day trip with your gear attached to the front of the board. A must do paddle. I could keep going.
Colorado is a beautiful state to paddle. So many rivers and mountain lakes. But I'm preaching to the choir. Stay warm.
