Colorado Stream Update: The St. Vrain currently has some of the best stream flows on Colorado's Front Range and is fishing great in the early mornings and evenings. Get out and fish!

Current Conditions at Saint Vrain:

Fishing has been fair to good and we are seeing some of the best caddis hatches in the early pm and late evening. Now is the time to tie on an Elk Hair Caddis dropped by a sparkle pupa for some great dry fly fishing results! Flows are ideal for fishing 7.5 foot leaders and 4x-5x tippet.

The St. Vrain is a dry fly fisher’s paradise. Get on the water now for some great dry fly fishing and great trips! Now is some of the best fishing of the year! All you need is a big attractor dry fly and a bead head dropper. Its dry dropper season on Boulder Creek! Bring a stimulator and a prince nymph and be prepared for a day of non-stop action! Lots of bugs are hatching but the trout seem to be eating just about anything and fly fishing trips have been good. The evening caddis hatch has been epic look for some excellent fly fishing reports to come! It is wet wading season bring your shorts and wading boots!  The fishing is good.  Clear skies and 60+ degree weather. The water temperature was between 44-47 degrees and Slightly Off.
