The River's Story

The Snake River begins at Webster Pass on the Continental Divide, with headwaters in two areas — one near Arapahoe Basin ski area, the other above the historic mining town of Montezuma. These segments meet near Keystone Resort before the combined flow continues 15 miles to Dillon Reservoir, where it joins the Blue River system that eventually feeds the Colorado River.↗↗

The river carries the complicated legacy of a century of silver mining in its upper watershed near Montezuma and Peru Creek. Between Keystone and Montezuma, the pH of the stream drops due to mineral runoff, leaving few trout in that stretch. But water quality has improved significantly through remediation efforts by the ski area, the state, and Trout Unlimited, and the lower Snake near Keystone — where the river runs through National Forest and resort land — supports a healthy, recovering fishery.↗↗

Fishing the Snake River

The Snake River is a moderately-sized stream with a cobble bottom, seldom covered with algae, making wading easy and the pocket water fun to work. Most sections within Keystone Resort are very quiet, seldom heavily fished, and lined with fir and pine trees. The river offers a distinctly different experience from its Gold Medal neighbor downstream on the Blue River — this is eager, beautiful small-water trout fishing.↗↗

Brook trout here are willing eaters. Unlike heavily pressured browns elsewhere, Snake River brookies will smash attractor patterns — Royal Wulffs, Stimulators, and bright Copper Johns all work well. The pocket water demands short, accurate casts into small pools behind boulders, with quick hooksets on any sign of a take. A light 2- or 3-weight rod makes the experience delightful.↗

The junction of Peru Creek and the Snake River is a productive area accessible from the Peru Creek trailhead off Montezuma Road. For those who want to go higher, above Montezuma beavers have created loads of ponds holding brook trout, and a hike to Chihuahua Lake at over 12,000 feet can reward you with Colorado River cutthroat.↗↗

Getting There and Access

The Snake River is accessed from US-6 near Keystone Resort, approximately 1 hour 30 minutes from Denver via I-70 to US-6 at Dillon. The river runs right past the resort village with easy walk-in access from parking areas and multiple crossings. The Snake River recreational bike path follows along or near most of the river from Keystone to the Dillon Reservoir shoreline.↗↗

For the upper river above Keystone, drive Montezuma Road (CR 5) from the resort. It's a dirt road that most passenger cars can handle in dry conditions, though 4WD is recommended for upper sections, especially early in the season. Multiple pulloffs provide walk-in access. A public parking area sits right at the river's inlet to Dillon Reservoir off Highway 6.↗↗

Best Time to Visit

The practical fishing window is July through September. June brings peak snowmelt runoff that makes the river too high and murky. By mid-to-late July, flows drop and clear, and August is typically the best month with active brook trout feeding on caddis, small stoneflies, and terrestrials. September offers cool water and brook trout in their vivid spawning colors. October brings early ice, and November signals the end of the season at this elevation.↗

In winter, the river is frozen and snow-covered — not a fishery at this altitude. But that doesn't mean you can't enjoy the area: ski Keystone's slopes in the morning, then explore the snow-dusted river corridor on foot or snowshoe in the afternoon.↗↗

Combining Your Visit

The Snake River's greatest advantage is its proximity to a full-service mountain resort. After casting a line, you can ride the scenic gondola to Dercum Mountain summit at 10,000 feet, mountain bike one of 55 trails, or simply walk to a pub in River Run Village for a beer. Guided fly fishing trips are available through Keystone Resort's adventure programs. The lower Snake River inlet at Dillon Reservoir attracts big brook trout and offers fishing with reservoir views.↗↗

For those who want a quieter experience, the stretch of the river between the Keystone golf course and the confluence with the Blue River is especially productive. Look for riffles, undercut banks, and pockets around boulders — and remember that within the resort, catch-and-release is required.↗↗
