Quote(s) of the Day: "We had a great day fly fishing in Colorado, the big fish were eating and we are pleased to have another great fly fishing report!"

Fishing Highlights:

The big fish were on the feed. We landed numerous rainbow trout in the 5-10 pound class. This is as good as fly fishing gets in Colorado and close to Denver and Boulder!

The fishing is fantastic.  Clear skies and 48-51 degree weather. The water temperature was between 36-39 degrees and Crystal Clear.
