Colorado Stream Update: Gotta love Boulder Creek in the winter, the crowds are thinning at and there are plenty of wild brown trout to eat your fly! Get out and fish before the storm hits!

Current Conditions at Boulder Creek:

Boulder Creek is low but can still make for some challenging but fun Colorado fly fishing. Now is a great time for dry fly fishing with a Parachute Adams size 18-20 dropped by small 22-24 Zebra midges. 9 foot leaders and 5x tippet will help get the job done.

Try an egg pattern (size 16) trailed by a small midge or mayfly (size 18-20). The water is low and clear and fly fishing reports have been excellent. The fish have seen a lot of pressure this season and they are getting spooky. Use light tippet and longer leaders to avoid spooking fish. Use a light fly rod to make delicate presentations. A shorter three weight fly rod is the best tool for the job right now. This your best bet for good winter days close to Denver and Boulder.  The fishing is fair.  Clear skies and 60+ degree weather. The water temperature was between 40-43 degrees and Slightly Off.
