We decided not to go as it was too low. People in kayaks run it as low as 250 cfs, but be prepared for a long day (or days) of boat abuse scraping and pitoning on rocks. It is none the less incredibly beautiful with long continuous class 3 whitewater with a few spicier rapids thrown in here and there. I'd do an overnighter if I had the time.
We lost a lot of snowpack early in the spring after dust storms and wind, bahh! Certainly shortening our season a bit, and the monsoons do not seem to be in full affect either so far this year. Rockwood Gorge is the most exciting part of the run for the least effort and at this level is splashy and fun class 4. Hike in after the trains have passed for the day, after 5:30. You can scout from the tracks. I'd go there, and may later this evening.
