Current Conditions at Boulder Creek:


Boulder Creek near Boulder is low and clear. We saw some fish but they were very spooky. A size 18 Black Rainbow Warrior was the best pattern. Most of the hookups came in the deeper plunge pools. There were a few anglers out and they all had the same report, slow fishing. The creek is low enough making waders optional. A stealthy approach is a must but also difficult on the tree covered banks. I would wait until the water bumps before making the trip.   The fishing is slow.  Overcast skies and 32-35 degree weather. The water temperature was between 36-39 degrees and Crystal Clear.
