South Platte River, Colorado
Cheesman Canyon & Deckers — The Front Range's most accessible world-class trout fishery
The South Platte River through Cheesman Canyon and the Deckers area is the most significant and accessible trout fishery on Colorado's Front Range — a Gold Medal water that sits just 60 miles from Denver yet delivers a quality of fishing that rivals destinations requiring a full day's travel. For the 3 million residents of the Denver metro area, this is home water, and the river has been managed with that significance in mind.
Cheesman Canyon is the crown jewel — a dramatic granite gorge where the South Platte cuts through billion-year-old Precambrian rock before opening into the Deckers valley. The canyon section is accessible only on foot (approximately 2.5 miles of trail from the lower trailhead), and this moderate barrier to access preserves a genuinely special fishery. The canyon holds exceptional populations of wild brown and rainbow trout in deep pools and pocket water that have seen generations of fly fishers.
The Deckers section — accessible by road — receives more pressure but offers excellent fishing for prepared anglers, particularly during the famous winter midge hatches that draw anglers from across the Front Range on cold January weekdays. The South Platte's winter midge hatches are Colorado's answer to tailwater winter fishing — when most streams are frozen or unfishable, Deckers and the South Platte continue to produce quality action.
Summer PMD and Caddis hatches provide the classic dry fly experiences, while the September and October period sees outstanding BWO fishing in the canyon as cooling temperatures trigger heavy autumn emergences.
Cheesman Canyon — Lower Trailhead
Park at the lower trailhead and hike 2.5 miles into the canyon. Well-maintained trail on canyon rim. The finest water on the South Platte. No crowds on weekdays.
Deckers — River Road
Paved road access along the river. Multiple pull-offs and formal access sites. Most pressure on weekend afternoons. Best early morning or weekdays.
Wigwam Club Water — Member Only
Private stretch in the canyon managed for trophy fishing. Member access only — contact Wigwam Club for information.
Brown Trout
Dominant in the canyon section. Wild fish averaging 14–18 inches with the canyon's largest exceeding 24 inches. Most active during fall BWO hatches and winter midges.
Rainbow Trout
More common at Deckers and in faster water throughout. Wild fish responding well to PMD and Caddis patterns in summer.
Winter midge fishing at Deckers on a warm January or February day is one of Colorado's great underrated experiences — go on a weekday for solitude.
Cheesman Canyon requires a 2.5-mile hike each way. Carry more water than you think you need — the canyon's elevation deceives.
The South Platte's fish are among the most educated trout in Colorado. Tiny flies (size 22-26), fine tippet (6x-7x), and perfect drag-free drifts are the price of admission.
September BWO hatches in Cheesman Canyon can trigger simultaneous rising throughout the entire canyon — be prepared for the most memorable dry fly afternoon of your year.
