Boulder Creek Fly Fishing Report Header

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.

This past week, I took out a fine fisherman by the name of Kyle to learn the art of Euro-Nymphing. We decided that Boulder Creek through town would have the right type of water to learn on, and the fishing has been good there this year. The DOW has stocked the lower sections, from Eben G. Fine to just past the Public Library, with a Hofer strain of cuttbows. These fish are aggressive, and by the looks of their bellies, eating well.

We started our day out by the Justice Center, looking for the bigger deep holes, as the fish have moved into their wintering holes. Find these holes and you will find the fish. Fishing the large man-made holes through town provided the perfect water type to teach Kyle how to tight line nymph. We used the trusty SAGE ESN in a 10ft. 3 wt., and the Greys Streamflex in the 10ft 2wt version. One rod was rigged “Spanish style” that is with a long 20-30 ft. leader to the sighter and then 5ft of tippet to the first fly. The second rod was rigged with a slightly cut back 9ft 4x leader tied to a Strike Foundry curly. From the curly to our lightly weighted flies was about 3-4ft of tippet. The flies we fished today didn’t matter as much as the holding water did. If you’re thinking about making a trip out the creek on a nice day this winter, just focus on any of the water that is deeper than 3 ft.

Fish are eating a variety of things, but your best bet are small bwo nymphs and midge larva, sizes 16-20. A good two fly rig for BC right now would be a pink SJ followed by a small red zebra midge, or small pheasant tail.

Overall our Euro Nymphing trip went well and we caught 25-30 fish with this super effective method!
