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.

Fishing Report Date: 04-13-2015

I noticed that flows had come up some out of Barker Reservoir on my drive down over the weekend, so I decided to give some of the juicy looking water up high a go. I spent most time around the Castle Rock climbing area just a few miles below Nederland.

The water is still crystal clear that high, so sight fishing was fun and easy. There is a thick layer of muck on the streambed at the moment, so after starting out with a euro-rig and picking up too much junk every other cast, I switched over to a shallow dry-dropper rig. I ran a size 18 parachute adams up top and mixed up the dropper, although it usually always included something with a tungsten bead so it would get down quickly.

I had a few takes on the dry, and saw a few fish coming up sporadically, but for the most part it was the nymphs that were pulling fish. Successful nymphs included #20 mercury black beauty, #20 mercury red zebra midge, #18 Poison Tungs in Blue, Black and Red variations and size 18 Brush Hogs.
