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.

After several days of melt, I went to Boulder Creek to check it out. As usual I took my favorite BC rod; a Sage 2wt Circa. By the way, the only rod better for BC than this would be made out of bamboo. There is a lot of work being done around and in the creek so combined with our recent melt there is significant stain in the water from Four Mile down. I started in the clear water above that but below the tunnel. Above the tunnel it is still pretty locked up, but that should change within the next couple of days as this heat wave moves through.

The water temp is predictably below 40 and the fish are generally on the bottom taking small insects. I got most of my fish on a #20 Tailwater tiny. Although, I got an inspection on a Hippie Stomper. One of the good things about BC since the flood is that there is a greater variety of fish species and size; like this yearling Bow:

I then decided to try the stained water and caught a few on a pink Squirmy Wormy with a gold bead in the first climbing area. I finished in the Kayak pools above Eben G where it was slow, but I did get to see two large Bows come up to kiss my Royal Chubby.

Consider the food, fish, and terrain, I’m expecting great things from BC this year.
