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.

Took advantage of the nice weather and did some checking in on Boulder Creek over the weekend. As of Saturday it was open from around the justice center down. Everything from there up was iced over and out of play. Super low flows are keeping the majority of the fish in the deepest holes throughout town. Found larger fish in the library section. Some fish were holding in the shallows near the edge basking in the sun. Many times these are prime targets for a really shallow dry-dropper rig. Go small up top (think 20-24) for the dry and use an unweighted midge emerger trailed behind it. If you’re focusing on the deep stuff, get heavy and let it soak. An typical deep indicator rig will be the best bet for these holes. Have some type of attractor up top (Prince variant, Walt Worm, Jake’s DB Worm, Tung Surveyor, Copper John) with something tiny (#18-22 – zebra midge, pure midge, mercury midge, top secret, black beauty, Blue Poison Tung) trailed off the bend.

For the most part the fish seemed to be in the winter doldrums. They would eat, but most of the time it required multiple force feedings before they were willing to play. Look for the warmer weather to get some bugs going which should wake them up a bit. Plus, it doesn’t matter how many you end up with if you can even convince one to eat a dry on a JANUARY day!
