Colorado Stream Update: At 17.5 CFS at Lyons, Colorado's St. Vrain is flowing well and fishing has been fair to good on this iconic Colorado river. It is no wonder why famous writer's like John Gierach call the Vrain, Home.

Current Conditions at Saint Vrain:

Now is a great time for a visit to the Vrain, fishing has been fair to good and anglers have been productive with nymph fishing and dry & dropper fishing rigs. 7.5 to 9 foot leaders and 5x-7x tippets.

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. The brown trout are spawning. Watch your step to avoid damaging spawning beds. Try an egg pattern (size 16) trailed by a small midge or mayfly (size 18-20). 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. A shorter three weight fly rod is the best tool for the job right now.  The fishing is good.  Clear skies and 60+ degree weather. The water temperature was between 40-43 degrees and Slightly Off.
