I would check the Colo. Game and Fish web.. My step daughter just moved to Carbondale, Colo. area.. There are a couple famous fly waters near there..
But the Game and Fish has a pretty good web on fishing.. I looked up warm water fishing and found lots of info.. Something you might keep in mind, the runoff here is very high in most of Wyoming.. I don't know about Colo.. But you might want to look into lakes.. Not as cool as wading a stream, but some great fishing can be had there..
