Colorado Stream Update: The St. Vrain is looking good and both the public and private sections have been fishing better than average for quality browns and rainbows.

Current Conditions at Saint Vrain:

Now is a great time for heading up to old iconic Lyons, Colorado for some quality fly fishing. If you feel like scratching the itch give us a call or visit our website to try some world class fly fishing on our very own Williams Ranch. Now is a great time for searching the water with dry and dropper rigs and shallow nymph rigs.

The fly fishing has been great, good hatches of Blue Winged Olives and midges will excite and challenge all levels of anglers. The creek has been on fire! For a nice change of pace try stripping micro black streamers. The best results have been with small black wooly buggers and Belly Ache Minnows. The creek has been producing some better than average this fall! Nymph rigs and streamer rigs have been producing big fish in the creek’s deepest slots. Try an egg pattern (size 16) trailed by a small midge or mayfly (size 18-20). 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 56-59 degree weather. The water temperature was between 40-43 degrees and Slightly Off.
