Colorado Stream Update: The key to fishing the St. Vrain is finding open water

Current Conditions at Saint Vrain:

The St. Vrain through Lyons isn't completely locked up so areas of the creek that receive high sunlight will most likely be fishing well. Nymphs like size #20 micro-mayflies, #20 black beauties, and size #20 black zebra midges will work well under a strike indicator.

The fishing is slow.  Clear skies and 20-23 degree weather. The water temperature was between 36-39 degrees and Crystal Clear.
