Boulder Creek

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.

Fishing is truly on fire right now on Boulder Creek. Barker reservoir stopped spilling over last week and the water has quickly come down to the perfect level. Many were worried about the level of bug activity we would see post-flood, but as we expected, they are still there and very active right now! The fish seem to be plump and well fed too, which is a great sign!

Just about any technique is taking fish right now. Dry dropper rigs are getting ferocious strikes just about anywhere in the creek, but especially on tailouts behind boulders. With water levels coming down, a lot of the canyon is prime for euro-nymphing as well. Pick apart all the pocket water with heavy euro nymphs and you will pick up quite a few fish.

We’re seeing plenty of Green Drakes, BWOs, PMDs and Caddis throughout the canyon. Pick a fly that represents one of these classes of bug and you should be set. Some of the specific flies we’ve been having great success with include the Hippie Stomper, Psycho Prince, Rainbow Warrior, and Drake Cripple.
