Overview

Fly Fishing Lower Boulder Creek Through Town

Lots of small trout, plenty of pockets and a path along the water make this an easy place to sharpen your short game

Lower Boulder Creek through town is a small freestone creek with plenty of trout, an easy walking path right along the water and a lot of holes, runs and riffles packed into a short distance. The trout are mostly small rainbows, cutbows and browns. They're usually more opportunistic than picky, so this is a good place to work on the short game: reading a pocket, landing a fly where you meant to and getting a clean drift before the current grabs your line. If you try to stick to your traditional overhead cast, you'll find more trees than fish. A short sidearm cast or a roll cast that stays under the branches will put you on far more trout than a long, pretty loop that ends up in a cottonwood.

Read the complete overview

The fishing follows the creek's freestone rhythm. It fishes best roughly between 50 and 400 cfs, rises with spring snowmelt and settles into lower, clearer water from late summer into fall. Spring through fall is the prime stretch. Winter is still worth a look, though, because when the temperatures warm up you can find fish even in the dead of winter in the holes. Midges, Blue-Winged Olives, caddis, Pale Morning Duns, small stoneflies and summer terrestrials all have a place in your box, and a simple dry-dropper or a single dry covers most days.

This is a popular town creek, and in summer especially you'll share it with people on the path and in the water. The easy fix is to move on to the next riffle and let the first one settle. From the upper end of Eben G. Fine Park downstream to 55th Street, the city reach is limited to artificial flies and lures, and trout must be released immediately. The path gets you close to the water, but a path or a bank across from a house doesn't automatically mean public fishing access, so use the signed public approaches.

Water typeFreestone

A freestone creek that rises with spring snowmelt and drops through late summer and fall. It fishes best roughly between 50 and 400 cfs.

Water sizeSmall

Small water with lots of holes, runs and riffles, and trees over much of it. Short casts are the rule.

DifficultyEasy

The trout are plentiful and fly choice is forgiving. The real challenge is casting under branches and getting a clean drift in short pockets.

AccessEasy

The Boulder Creek Path runs right along the creek. Use the signed public approaches and stay out of private yards.

Fish numbersMany

There are plenty of trout spread through the pockets, so moving to new water usually beats pounding one spot.

Fish sizeSmall

Rainbow Trout, Cutbow Trout, Brown Trout Expect mostly small rainbows, cutbows and browns. Light gear makes them fun, and quick handling makes for a clean release.

Same creek, wilder settingUpper Boulder Creek - Canyon SectionUpper Boulder Creek's canyon section is another small, easy freestone reach, upstream beyond town. Go there if you like this creek's pocket-water fishing but want it away from the town path.It's fishable from spring through fall rather than year-round, and the canyon is different enough that it needs its own plan. Don't just bring the town approach upstream.Another easy town creekSt Vrain Creek - Town SectionSt. Vrain Creek's town section is also a small, easy freestone reach in town, and the short-cast pocket game carries over well.It's a separate Front Range trip and is fishable from spring through fall rather than in all four seasons.
