Colorado Stream Update: Saint Vrain is fishing great!

Current Conditions at Saint Vrain:

The St. Vrain is finally recovered from the flood. We are seeing great fishing in the canyon and in Lyons. Lots of larger than average fish are being caught on a well presented dry fly. Flows are around 70cfs which makes for perfect summer conditions.

The fishing is great.  Clear skies and 60+ degree weather. The water temperature was between 60+ degrees and Crystal Clear.
