Colorado Stream Update: The water is a bit off-color through Lyons but the fishing is great!

Current Conditions at Saint Vrain:

The fishing on the St. Vrain has been quite good despite the off-color tint to the water. The key here is to fish soft holding water. Trout are holding close to the bank and behind structure where they can find a respite from the fast current. With that said, it's also the beginning of Dry-Dropper season on the St. Vrain! Amy's Ants, Chubby Chernobyl Ants, Charlie Boy Hoppers. Yellow Stimulators, and large Caddis are all working great as your lead dry fly. Trail that with 18-20" of 4-5x tippet with a Graphic Caddis or black RSII and you'll be good to go!

The fishing is good.  Clear skies and 52-55 degree weather. The water temperature was between 40-43 degrees and Slightly Off.
