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: 04-29-2016

Antonio was out on the creek yesterday.  Here is his report.

“Cold and Snowy day at B.C. Canyon (30 to 37F).

The water above Four Mile Canyon still at a perfect level and pretty clear, but very cold.

The fishing in the first hours of day was very hard and we had some takes only around 10am. The real action came after 12:30, and with a small increase in the water temperature the fish started to feed.

Chubby on top, PT (sizes 14 and 16) and Jigged Caddis Pupa are still producing most of the fish. Elk Air Caddis, Parachute Adams, and Purple Haze can be very fun if fishing a single fly rig.

It is good to see that the fish are already spread out what make the fishing way more fun!”

As always, with weather like this, be careful driving up and down B.C. Canyon.  Roads can be icy and pullouts are less obvious.  If you are wearing felt boots, be extra cautious on the snow covered/ice covered rocks.

Good luck out there!
