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.

Have you ever though about some urban fishing in Boulder? Well we did and it turned out to be an amazing decision. We fished from the library all the way down to Arapahoe and had a very successful day.

The fish were sitting mainly on the bottom and very rarely came up to the surface. So we went from using chubbys and san juan worms to going to a straight line nymph rig with a good amount of weight to dredge the bottom.

The flies that we had the most success with were san juan worms, jigged HDA, jigged hairs ears, sow bug, pats rubber legs and jigged green drakes. Most of these flies did not need any weight since they are heavy already but some of the lighter trailers do need a weight near the fly.

Just because there are people in town does not mean it wont be a very good day. Stop by the shop and grab the flies that will help you catch 16+ inch fish in town.
