Overview
Upper Boulder Creek in Boulder Canyon
Small freestone pocket water below Barker Reservoir, with lots of willing trout that reward short, precise drifts.
Upper Boulder Creek's canyon section is the stretch below Barker Reservoir, where the creek drops through Boulder Canyon beside Boulder Canyon Drive. It's small freestone water made of plunge pools, rock-studded pockets, short riffles and narrow seams. Boulders, streamside brush and the canyon walls all limit your casting room. Rainbow and brown trout make up most of the fishing, and you'll catch the occasional brook trout. Most of the fish are small, but there are a lot of them. The canyon is easy to fish and easy to reach, so it's also a popular place.
Read the complete overview
Dry flies and nymphs work best on this section, and the fish are eager to eat a variety of insects most times. That doesn't mean any fly will work on every drift. Matching the hatch or using a bug seine will help you find the flies you need to catch a bunch of fish here. A quick look at what's crawling on the rocks or floating in the seams tells you whether to start with a mayfly, caddis, stonefly or terrestrial. After that, presentation does most of the work. Make short, accurate casts, get a drag-free drift through each pocket, and stay out of sight of the fish you're about to cast to.
Watch for one local clue. Around the junction with the Boulder Falls tributary, the water can look different in clarity and flow. If you notice that contrast, use it to decide where to fish before you think about changing flies. Work a short drift through the softer seam or behind a boulder near the edge before you start cycling patterns.
Freestone pocket water and riffles between boulders. Spring snowmelt and storms change the flow and clarity, so check conditions before you go.
Small water with short casts to pockets and narrow seams. Rocks, brush and the canyon walls limit your casting room.
Easy. The trout are usually willing, so the skill is in staying out of sight and getting a short, drag-free drift.
Easy, with the creek running close to Boulder Canyon Drive. Use signed public access only, because a roadside pullout alone doesn't mean you can fish there.
Many. There are plenty of trout in the pockets, so a good drift is often rewarded and it pays to keep moving.
Rainbow Trout, Brown Trout, Brook Trout Small. Most fish are modest rainbows and browns, with the occasional brook trout. This is fun numbers fishing, not trophy water.
Fit
Is the Canyon Section Right for Your Trip?
What this water rewards, and when another stretch will suit you better.
- Short dry-dropper or nymph drifts through rock pockets and small seams.
- Plenty of willing small trout and a good place to sharpen your drift control.
- A canyon outing where you can compare water clarity at different signed public stretches.
- A spring-through-fall day trip close to Boulder, with dog-friendly water where leash rules allow.

Other Boulder-Area Options
Nearby water for winter or more technical fishing when the canyon isn't the right call.
Closer four-season option downstreamLower Boulder Creek - Town SectionLower Boulder Creek is downstream in the same corridor and is also easy small freestone water. It's fishable in all four seasons, which makes it the closer choice once the canyon turns icy.It's town water with different access, and the city special regulation runs from the upper end of Eben G. Fine Park downstream to 55th Street. Check those rules for that reach instead of applying the canyon's.
Year-round small tailwaterSouth Boulder Creek - Tailwater SectionSouth Boulder Creek's tailwater section is a small tailwater fishable in all four seasons. It's a good choice when you want winter fishing or a more technical day.It's rated medium difficulty, and tailwater trout can be more selective, so expect smaller flies and more precise drifts than in the canyon. It's a separate water with its own approach.
