Colorado Stream Update: The trout of St. Vrain are feeding heavily on Blue Wing Olives right now.

Current Conditions at Saint Vrain:

These trout are starting to feed on the surface more and more, so for you dry fly lovers get on over here to the St. Vrain! Parachute Adams and BWO Comparaduns have worked the best for rising fish, but trail your dry with an olive RSII to cover different water columns as well.

Guides report that the St. Vrain is on fire! Midges and mayflies are everywhere. The water is low and clear and the fish are hungry. Fly fishing trips have been great.  The fishing is good.  Clear skies and 44-47 degree weather. The water temperature was between 40-43 degrees and Crystal Clear.
