St. Vrain Creek River Report

St. Vrain Creek River Report

11-4-2025

Flows took a big dive, and are currently below historical average. So, look for the deepest water available, and approach from behind. We have been using dry droppers. While the dry isn't guaranteed a fish, on nicer days it will add a bonus fish or two to the net. It'll also spook less fish than a indicator. One recomendation with the cooler water is to fish in areas with sun to start, especially in the AM. Also, the South Fork will be tough in the National Park area, with some cold temps there. Hatches continue to be midges, BWO's, and Caddis. Midges have been the most prevelant hatch.

...

For Dries, use a Hi Viz Midge, Red Butt Caddis, Purple Haze, Hi Viz Parachute BWO, Superman Caddis, High Vis BWO, Mole Fly, and a Hippy Stomper.

...

For nymphs, use a RS-2, Zebra Midge, Baby Gonga, Poison Tung Juju Baetis, Shot Glass Baetis, Godspeed Caddis, AR's Perdigon, Simple PTN, Thin Mint, Jigged Leech, Tung Stud, 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.
