Colorado Stream Update: Fish are on the bottom, make sure your flies are too

Current Conditions at Lower Colorado:

The Colorado is fishing so-so. The water is open and fish are feeding but few and far between. It is possible to see rising fish in softer seems and slack water, but the most consitent way to find an eat is nymphing. On big water such as the colorado, run a larger offering as your first fly. Patterns such as Pat's rubber legs, 20-inchers, and leeches serve this purpose well. Expect strikes to come on smaller midges though, in softer deep pockets. Fish are still in winter mode for the most part.

Time to head to Colorado‚Äôs western slope for some of the first fly casts of the year. For best results try fishing heavily weighted stonefly nymphs. Our guides suggest productive patterns like the Zebra Midge or Money Midge. The water is still cold so be sure and look for fish holding in more traditional winter fishing holes.  The fishing is good.  Clear skies and 36-39 degree weather. The water temperature was between 32-35 degrees and Slightly Off.
