Colorado Stream Update: With a stable flow in the mid-70s CFS, the Williams Fork has been in prime winter condition of late

Current Conditions at Williams Fork:

For the most part trout here are pooled up in deep, slow water which is pretty standard behavior for trout in Colorado. During the warmest parts of the day we are seeing trout move into riffles and sipping small midge clusters off of the surface. The crowds are surprisingly sparse right now making this a great option to get some quality trout to net as well as a little elbow room!

Tiny tippets and small midge and mayfly patterns are hooking the most fish. Try nymph fishing with different styles and sizes of midge patterns. Use a long 9’ or 10’ rod to get the most control out of your nymph rig. To imitate a midge cluster try using a Griffith’s Gnat (size 18-24). The winter fly fishing in Colorado is great.  The fishing is good.  Clear skies and 48-51 degree weather. The water temperature was between 36-39 degrees and Crystal Clear.
