RaceCourse/Pilar section of the Rio Grande II/III
Rio Chama Day run (monastary to Big eddy) II/III
both have bikable/hitchable shuttles. both are in right now, although the chama is probably higher on weekends
Upper Taos Box V
Lower Taos box (over 600cfs) III/IV
the other creeks are pretty marginal now
Southern CO= Animas, Piedra, Vallecito, etc...
Central CO= Arkansas River,lake creek,OBJ, and many, many others.
gunnison gorge, and westwater on the way back to utah are a good bet.
Colorado people will have better beta for you on whats running. (or look at the flows at the top of the page)
