St. Vrain Creek River Report

St. Vrain Creek River Report

4-1-2025

Not much has change don the Vrain over the weekend. Flows are starting to creep back up, but are still below historical average for this time of year. The canyon stretch to Button rock remains pretty skiny, with lots of spooky fish. Lyons continues to be the better bet, but expect some swimmers and sunbathers in the prime fishing pools. Hatches have been primarily Midges, but on cloudy days in Lyons you will see a few BWO's hatching. If you flip some rocks over you will see plenty of baetis, and caddis nymphs, which are a good idea to add. 

...

For Dries, use a Micro Chubby, High Viz Quill Midge, AR's BWO Emerger, Borrof's Midge, Mole Fly, Slick Midge, High Vis BWO, Griffith's Gnat, and a Hippy Stomper.

...

For nymphs, use a Perdichigon, Boroff's Homie, Juju Baetis, Rainbow Warrior, Rock Grinder, AR's Perdigon, Simple PTN, 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.
