I travel to Colorado almost every summer to fish for a few days. Typically, I visit in late July. This year I went out the last week of June due to low water. The water was low but the streams were fishable. The streams are still going to be low but you won't have to deal with elevated water temps and hopefully not as much wildfire smoke.
You may already know this but Fairplay puts you in reach of the South Platte ( I like Elevenmile Canyon), the Arkansas, and if you want to drive and the pass is still open the Taylor River. The Taylor is my favorite. It is where I stay when i go out there.
