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 a guided trip out on the creek between the bridge at the Red Lion and up to Doherty park. It was destined to be a good day as we hooked up on my first demonstration cast! Water clarity was great, and we spotted most of the fish we caught before ever casting to them. We had the best luck at the back of pools with a #18 Tungsten Pheasant Tail. Tying the PT with orange thread and a CDC collar really gets the creek fish extra excited! The larger, river right hole above the island held some very colorful Brookies. Every hole larger than about 4 feet in diameter was good for 4-5 fish. Our rig was a 9′ 5x leader, 12″ of 5x tippet to either a #16 Royal Chubby or a #16 Red Hippie Stomper, followed by 18″ of 6x to the dropper.

Great Day on Boulder Creek
