yup,it's possible. theres still a few commercials going out... big river and the Taos companies. they prolly will til october...
I took six loads in 13' achilles down for a whole summer down to 150cfs back in....umm, 2000. I wouldn't call it fun. let's just say it was character building. we didnt have any smaller boats then.and the boss (still doesn't) believe in loading a raft optimally.just maximally.... :/
Obviously, the smaller the craft, the easier it will be. R2ing a really small raft would be fairly painless if you know the lines. you will get stuck like 500,000 times in 5 miles if you didn't. and only half that if you do know the lines.
I did it with Logan, Glenn & Scott last week in tupperware and we still found that it floated fine if your expectations aren't too high.
and you have beer.
I have lots of splat rocks and channels to stern squirt in and flip over without concussing myself, but now its dropped even lower . the pool below souse hole is still plenty deep for rolls.... the waters warm... beats a swift kick in the pants...
But.....since you're asking about rafting I'd say just skip the RC (and the fishing) ... and go float the day section of the Rio Chama....600cfs is nice...and its supposed to stay at 600 for sep/oct.... there is actually more to the rapids at medium flow then higher. the chama is virtually featureless at 1000.its still class II(-III) but at least there is water. the good fishing is prolly over in farmington on the san juan. but i am pretty ignant on the fishing side of things so thats all I could tell you.
