Colorado Stream Update: The Williams fork is still in a winter state, but fish are feeding regularly.

Current Conditions at Williams Fork:

The fork continues to produce consistently for those nymphing slow and deep. The river is still in a bit of a winter state, and nymphing tiny midges remains the best way to trigger an eat. Run a slightly larger point fly, and trial a midge off the back. Expect strikes to be soft, as fish are still moving slow. start your drifts higher in the water column and work towards the bottom by adding split shot.

Our guides suggest productive patterns like the Zebra Midge or Money Midge.  The fishing is fair.  Clear skies and 32-35 degree weather. The water temperature was between 32-35 degrees and Crystal Clear.
