the mama chama is just about the type of float you're looking for- but it doesn't get releases until july/ august for commercial (or otherwise) permits. it seems like there should be excellent runoff,but the lower chama is dam release from el vado dam. there was random high flows early season one year, to pay water debts down south, but the whole area was closed due to fire danger while the chama ran 1000+. go figure. the three day is super scenic rowing with your feet up on the beer cooler, (tecate- cuz you're in new mexico) with 8 miles of class 2 (3- with flows) on the last day. below 500 cfs it's not really worthwhile (esp. with a loaded gearboat) but we have had to make it to the take out when they turned the water off early at @ 300 cfs (beergoggled
rock dodging!) the day section of the chama has decent play,and is also great for beginning paddlers (cold water tho!!) or camping and doing laps. the shuttle is long, or the folks at the put in can do it for @ <$100. it is a designated wild and scenic river, so a firebox and groover are mandatory, as per the BLM; and theres usually a ranger at the put in.- the taos office does the permits...private permits aren't too hard to get- sometimes... i think... we also rent gear and run commercial trips @ santa fe rafting.
the rio grande is sweet, and it is already flowing- thats all two of our rivers in nm (lol)- not counting creeks. hope this helps- for when there is water on the chama!
see you on the rio-
