Colorado Stream Update: "Colorado's St. Vrain is fly fishing great with dry flies and droppers. We are catching lots of quality rainbow trout and our fly fishing guides have come back with excellent fishing reports."

Current Conditions at Saint Vrain:

We caught some nice fish in the shallow riffles that were rising to emerging midge patterns like a size 20 Griffith's Gnat. It was awesome to see some of the first rising fish of the spring fly fishing season!

The fishing is good.  Clear skies and 48-51 degree weather. The water temperature was between 36-39 degrees and Crystal Clear.
