Colorado Stream Update: Boulder Creek

Current Conditions at Boulder Creek:

Boulder Creek is slowly coming into summer form. Time to get those dry flies out for the upper canyon. Nymphing the deeper pools with nymphs are producing some nice fish. Dry dropper rigs are working better further up the canyon. Midge and beatis patterns are working the best under the indicator. Get out and check out Boulder Creek.

The fishing is good.  Partly Cloudy skies and 52-55 degree weather. The water temperature was between 52-55 degrees and Slightly Off.

Angling University: Up your game.
