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.

From FRA Guide Matthew G:

The Creek is fishing well (~30 fish in just under 5 hours!), plus lots of rises and looks.  Not to put too fine a point on it, but the best flies are basically anything that floats, with anything that doesn’t as a dropper, haha… Seriously though, I had the best luck with Royal Chubbies, and Crystal Flash Stimulators on top, both in size 14-16, and 2 bit hooker, and rainbow warriors on the bottom, both size 18.  I saw some yellow sallies and a nice PMD hatch in the evening.  I think we are starting to get into spinner season in the evenings.

As for where the fish are, they have moved out of the skinnier, faster water where they were a couple weeks ago and into deep slow pockets behind rocks and faster riffles and chutes.  Fishing areas with multiple falls and small, tough-to-access, deep holes was most productive by far.  Don’t neglect any fishy water, and try to hit EVERY hole.  The shores were also productive.  Cloud cover was very beneficial.

Other than that, business as usual in Boulder Canyon.
