St. Vrain Creek River Report
10-27-2026
Flows are up a bit thanks to recent rains. Fish all up and down the Vrain will be in the deeper water, and can be a bit spooky. Dry droppers have been excellent here, as despite the cooler water, the fish are still looking up at times. Hatches continue to be midges, BWO's, Terrestials and 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.
