St. Vrain Creek River Report

St. Vrain Creek River Report


Flows have dropped a bit, but are still above average. There is open water from Button Rock passed Lyons, though a few shady areas have ice shelves in the canyon. Fish are pretty spooky with the clear water, so a dry dropper and lighter tippet will spook less fish. Midges are the primary hatch, and on the less windy days fish will ride to a well presented dry, though the majority of the action is subsurface.


For Dries, use a Micro Chubby, Morgan's Midge, Purple Haze, Parachute Adams, AR's BWO, Griffith's Gnat, High Vis No See Um Midge, and a Stimulator.


For nymphs, use a Jigged Zebra, Juju Baetis, Walt's Worm, Glo Bug, Prince Nymph, 2 Bit Hooker, Rainbow warrior, Zebra Midge, Pat's Rubberlegs, and RS-2.

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.
