Colorado Stream Update: Boulder Creek and Boulder Canyon are on fire! The fishing has been fair to good and hatches have been prolific. Now is a great time for rock hopping Boulder Creek with a dry and dropper rig.

Current Conditions at Boulder Creek:

Now is a great time for prospecting the creek with dry and dropper rigs. A Stimulator or Elk Hair Caddis size 16 makes for a great dry fly when dropped with Copper John and BH Pheasant Tails. Look for fish to be rising in the slow pockets and seams. 7.5 foot leaders and 4x-5x tippet will fool the wily brown trout that call Boulder Creek home. Good luck and have fun on Colorado's Boulder Creek!

Our local creeks provide the dry fly angler with amplitude of opportunity close to Denver and Boulder! Get on the water now for some great dry fly fishing and great trips! Now is some of the best fishing of the year! All you need is a big attractor dry fly and a bead head dropper. Its dry dropper season on Boulder Creek! Bring a stimulator and a prince nymph and be prepared for a day of non-stop action! The creek is fishing good in the morning, leaving the afternoon available for tubing and touring downtown Boulder! The creek may be the best fishing on Colorado‚Äôs Front Range right now. It seems as though a brown trout is feeding in every pocket! The creek is on fire! Attractor dries and bead head droppers are producing fish left and right. Guides are catching many fish sight fishing. Lots of bugs are hatching but the trout seem to be eating just about anything and fly fishing trips have been good. The evening caddis hatch has been epic look for some excellent fly fishing reports to come! Lots of stoneflies ensure the dry fly fisher an exciting day on the water. It is wet wading season bring your shorts and wading boots!  The fishing is fair.  Clear skies and 60+ degree weather. The water temperature was between 44-47 degrees and Slightly Off.
