Re: July trip to New Mexico & Colorado
Southern Colorado info
Spud Lake: haven't fished it for several years but last time they were rising in the evening.
I would rather see you camp near Hermosa, Cascade and Lime Creeks instead of by Molas. All three are great for numbers of small, easily fooled fish, if you can walk a bit. I only ever fish dries on them.
Durango is a great town (I am here in the summer) for a break from fishing - resturants, shopping, etc.
San Juan; not the experience some people are looking for. There are lots of good size fish in the San Juan but the experience is not without crowds and you are not getting into the back-country. Anyway, a guide would be a good idea if you don't have a lot of experience fishing tailwaters.
Your schedule seems a bit ambitious, or it's my age. You could spend all your vacation fishing the Durango area and spare travel days.
