St. Vrain Creek River Report
6-5-2026
Flows are back down, but still decent all things considered. That being said, flows are still strong, so be careful while wading. Fish will be in areas that block current, and the pocket water can fish good. In town, you'll have tubers and swimmers to contend with. Otherwise, the Vrain in the Park has been fishing great! Hatches continue to be midges, BWO's PMD's and Caddis.
...
For Dries, use a Super Man Caddis, AR PMD Adult and Emerger, Griffith's Gnat, Purple Haze, Foam Run Caddis, AR'S BWO Adult and Emerger, Film Critic, Fin Fetcher Caddis, Dry Humper, Sparkle Dun BWO and a Chubby Chernobyl.
...

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.
