Colorado Stream Update: Fishing has been good!

Current Conditions at Waterton:

Fishing has been decent through Waterton. Expect flows and water clarity to fluctuate with the warmer weather as of late. The bug life has ramped up this week and fish have been caught looking up, in softer water. The best bet for an eat remains sub-surface, try running a hopper dropper rig. Although the hopper might not see too much action it makes for a very sensitive nymph rig.

The fishing is great but the crowds close to Denver are thick! Lots of bugs on the water and the fish are eating.  The fishing is good.  Overcast skies and 52-55 degree weather. The water temperature was between 40-43 degrees and Slightly Off.
