Colorado Stream Update: Fishing has been decent - Expect flows to rise soon

Current Conditions at Williams Fork:

Fishing has been good to great on the Willy's. Nymphing is producing the most strikes. Smaller flies are getting the job done, like Zebra midges in black and green. Small PT's, Juju Baetis, and top secrets are also ideal patterns. Flows are steady bust should increase soon. Some rainbows are staging to spawn so keep an eye out. Make sure to adjust your depth accordingly as incresing flows will spread fish out.

The weather is warming up outside and it is beginning to look like spring again! For a good chance at hooking a big fish try dead drifting mayfly patterns. Our guides suggest productive patterns like the Zebra Midge or Money Midge.  The fishing is good.  Partly Cloudy skies and 44-47 degree weather. The water temperature was between 36-39 degrees and Slightly Off.
