St. Vrain Creek River Report
St. Vrain Creek River Report
3-10-2025
Flows have dropped a bit, but the water is warming with the nicer weather. Here has been a good bet to target fish with dries, as on the nicer days, plenty of midges are hatching. Observe the fish's nose. If it breaks the surface, they are feeding on adults. If not, try a emerger pattern. Hatches have been primarily Midges, however there are a lot of cased caddis in the river right now. While these are not yet overly active, it would be a good idea to have a few patterns on hand for when the water warms.
...
For Dries, use a Micro Chubby, High Viz Quill Midge, AR's BWO Emerger, Borrof's Midge, Mole Fly, Slick Midge, Palm's Emerger, Griffith's Gnat, and a Hippy Stomper.
...
For nymphs, use a Perdichigon, Boroff's Homie, Foamback RS-2, Rainbow Warrior, Chocolate Thunder, AR's Perdigon, FRA Frenchie, Zebra Midge, Jigged Leech, Aero Baetis, and Foam Wing Emerger.

Fly Fishing the St. Vrain
The creek is full of opportunistic fish that are eager to take a dry fly, so take advantage of the great caddis, blue wing olive and terrestrial fishing. The midges that call the St. Vrain home are active all year and are always a safe bet come the colder months of the year. This is a great chance to get out and test some of those midge patterns that you have been drooling over all winter. The Fishing in the town of Lyons can be fantastic.
