Colorado Stream Update: The water is low and clear but now is a great time to go out and fish with a dry-dropper on the St. Vrain!

Current Conditions at Saint Vrain:

The baetis life cycle is in full swing on the St. Vrain through Lyons right now. Copper Johns and Prince Nymphs are working great sub-surface imitating the baetis nymphs while a traditional adult Blue Wing Olive on the surface is inducing a lot of takes as well. As these trout start to turn on their metabolisms from their winter hibernation, early spring on the St Vrain is a great place to get your line wet and catch a few while you're at it.

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