Colorado Stream Update: Walker Ranch is fishing very well at the current flow of 220 cfs

Current Conditions at South Boulder Creek:

Now that the flow is up and running fish have moved around and are feeding on a variety of insects. Golden Stones and Caddis Larva are hooking lots of fish under an indicator. Black Streamers like an articulated Sex Dungeon are also hooking some of the larger fish in this stretch. While the flow remains in the low-200s its a good time to hit South Boulder Creek below Gross Res!

The water is high but we are still catching fish. Be persistent. The fish are still there! Fishing is decent close to Boulder. The key to catching fish is working the slow seams and holes.  The fishing is good.  Clear skies and 24-27 degree weather. The water temperature was between 32-35 degrees and Crystal Clear.
