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 up to 18″+.

Fishing Report Date: 01-14-2018

Today we went out to fish on Boulder Creek for a little bit while before the temperatures change and the snow comes. We had a great day with very active fish, but it came with limitations. The most productive times we found were from 11:30 to 2:30 and once the sun began to lower and the temperatures drop, fishing was poor.

We found our best luck in fishing the deeper pools and runs. There were some fish holding in the shallow waters but they were not interested in eating. Either way, we utilized a dry dropper rig for pretty much the entire day. One major adjustment we made to the rig was to add extra length onto the dropper. Instead of the standard 12-16inches, we extended it from 18-30 inches depending on the depth of the pool.

Working patterns for dries were no existent, but we did see a few refusals on a split wing Adams(16) and a missing link(16). Nymphs stole the show and really produces when we used poison tungs(18-20), midge bombs(18-22), zebra midges(20-26), pellets(16) and mercury midges(16-20).
