Colorado Stream Update: The Willy's Fork is fishing decently

Current Conditions at Williams Fork:

As winter really settles in fish are being found more and more in deep holding areas. Target the warmest part of the day and be sure to get your flies low and slow. Nymph-rigs fished in deep holding runs with an attractor fly such as a Prince, Hare's ear or leech followed by a selective emerger or midge offering is a good place to start. Fishing a streamer is never a bad idea. The lower section near the Colorado is also fishing well with deep nymph rigs.

Winter fishing conditions are in effect  The fishing is good.  Clear skies and 32-35 degree weather. The water temperature was between 32-35 degrees and Crystal Clear.
