Colorado Stream Update: The St. Vrain still has open water

Current Conditions at Saint Vrain:

The mornings are getting chilly so expect fish to be found slow and low, on nymph rigs. Target seams, current breaks, and deep pools that provide holding areas. Flies like princes, Hare's ears and worms are landing some nice fish beneath. Follow these offerings with a more selective pattern like small barrs emerger, or an RS2. Midges are becoming a major part of the trouts diet as we move into the cold months. Don't be afraid to swing a streamer! Small leeches, slump busters and woolybuggers are good ideas. Expect the warmest part of the day to be the most productive. Expect more ice to show as the next round of winter storms hits.

The fishing is good.  Clear skies and 36-39 degree weather. The water temperature was between 32-35 degrees and Crystal Clear.
