Boulder Creek Fishing Report

Our Boulder Creek fishing report will give you an idea of what flies to use and general conditions you can expect. Boulder Creek is one of Boulder’s most prized possessions, running from Barker Reservoir through town past the campus of CU and out into the flats of Colorado. From start to finish this is a fine trout fishery full of wild browns, rainbows, and even some colorful brookies up towards the town of Nederland. If you can really devote some time to fishing the creek there are even a few cutthroats to be found. Go for the Boulder Creek grand slam!

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 Boulder Creek 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 caddis hatches on the creek makes for some of the best evening fishing Boulder has to offer.  A simple dry fly with a dropper hanging off the back will light up fish all day long and into the night.

The creek fishes well from start to finish, hitting bigger browns outside of town, or even in town, more rainbows than you can stick in one day up in the canyon and brookies that will keep you grinning until dark near the upper stretches of the creek. The fish size averages around 8in, but there are plenty of larger fish to be had in the creek up to 18″+.

It looks like we have seen the last snow and it is starting to warm up. That means the fishing is also getting hot and they are feeding on the bigger bugs.  We probably have a short window on Boulder Creek before the water comes up.  With a nice warm forecast, the fishing should warm up in the morning and be productive all day

George, Hanna, Caroline, Emily, Elizabeth and I went out to Boulder Creek for a mid day fishing trip and found great success. The water has come up and is a hint off color but the visibility is still good. And the fish are actively moving to grab food out in the faster currents.

We concentrated on the upper canyon using a dry dropper set up. Working dries included Chubby Chernobyls, Hippie Stompers and JC Specials. We kept the sizes smaller since it is earlier in the season, so 14 to 16. We had a few takes here and there but the bigger fish seemed to be more willing to take the fly.

Working nymph for today were Beaded Pheasant Tails, Rainbow Warriors, Brushhogs and Frenchies. All of the sizes I used were in the 16 to 18 range. I used 16 inches of tippet from my dry to ensure that the nymph sank deeper where the fish seemed to be held up.

Overall the creek was fishing great and the dry fly action was picking up tremendously.  Be sure to stop by the shop for you gear and book a trip with us.
