Boulder Creek

Latest Guide Report

Report by: Randy Hanner

It was chilly most of the day, with temps in the 40-50s. We fished a bit early at castle rock. The fishing was a little tough with the cold weather. We used dry droppers for this trip until the afternoon when we fished nymphs a bit. The fish weren’t rising at all and all of the strikes came on the droppers. We were able to get a couple on black zebra midges. Later in the day we moved close to Eben G.Fine park and fished the slower moving pools with red San Juan’s and bright flashy midges on our nymph rigs. We were able to get a few on the nymph rigs with the san Juan’s being the flavor of choice. Overall the fishing was a little slow I think due to the fresh cold front that came in the night before. We had a nice time out, and on a warmer day I think my guys would’ve done very well.

About Boulder Creek Fly Fishing

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 up to 18″+.
