St. Vrain Creek River Report
9-16-2025
Flows are pretty steady, and the water is starting to cool off nicely in Lyons. Fish will eat dries, nymphs, and streamers, so pick your favorite technique. Just don't forget to do a good swing at the end of your drift. This tactic will only get better as the water continues to cool. Hatches continue to be midges, PMD's, BWO's, and Caddis. Small Caddis have been the most prevelant hatch.
...
For Dries, use a Elk Hair Caddis, Red Butt Caddis, AR's PMD, Hi Viz Parachute BWO, Superman Caddis, High Vis BWO, Patriot, and a Hippy Stomper.
...
For nymphs, use a Hun Caddis Pupa, Zebra Midge, Split Case PMD, BH Peacock Nymph, Juju Baetis, Bubble Back Emerger in PMD, Godspeed Caddis, AR's Perdigon, Kelsar, Thin Mint, Jigged Leech, Panty Dropper PMD, and Twisted Caddis.

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.
