Fly Fishing the Upper Arkansas Near Leadville

Wild trout, world-class hatches, and a river that begins right in your backyard. Here’s your season-by-season guide to fly fishing the Upper Arkansas River from Leadville, Colorado.

There are rivers you drive hours to reach — and then there's the Arkansas. For guests staying at The Silver Rose of Leadville, one of Colorado's most legendary trout fisheries practically starts at your doorstep. The headwaters of the Upper Arkansas River originate just outside town, born where Tennessee Creek meets the East Fork of the Arkansas, and the fishing is exceptional from late March all the way through November. The Upper Arkansas flows through high alpine meadows, past granite boulders, and into canyon country — carrying wild brown and rainbow trout the entire way. Colorado's Division of Wildlife once called it the state's most popular fishery.

Late March — May

Spring Awakening

As the river wakes from winter, Blue-Winged Olives dominate the morning hatches on overcast days. The legendary Mother's Day Caddis (Brachycentrus) begins building downstream in April — one of the great dry-fly events in the Rocky Mountain West. Nymph in the mornings, watch for surface activity by midday. Note: late May runoff can blow out flows, so fish early in the season.

High Summer Action

Once runoff settles — typically by late June — summer offers the most diverse and exciting fishing of the year. Golden Stoneflies and Yellow Sallies bring fish to the surface on the edges and riffles. Caddis continue into evening, and Pale Morning Dun mayflies produce memorable dry-fly action. A dry-dropper rig shines here: an attractor pattern on top, a nymph below.

Fall's Blue-Winged Olive Reprise

Autumn on the Upper Ark is a quiet reward for those who return after the summer crowds thin. Blue-Winged Olives re-emerge with the cooler, overcast days that brown trout love. Midges begin to matter again. The browns are pre-spawn and opportunistic — streamers stripped through deeper runs can draw explosive takes from the river's largest fish.

Winter Midge Solitude

Winter fishing is not for everyone — but those who embrace it find deep, glass-clear pools and zero competition. Midges reign supreme. Focus on slow, deep water where trout conserve energy, and fish between 10am and 3pm when temperatures nudge upward. BWO hatches can surprise you on the warmest afternoons. Thin tippet (6X–7X) and a light touch are essential.

Know Your Quarry

The Upper Arkansas is home to wild, naturally reproducing brown trout and rainbow trout, with browns making up roughly 75% of the fishery. Expect fish in the 12–18 inch range throughout the season, with larger browns possible — especially in fall.

The river fishes best between 10 a.m. and 4 p.m. Catch-and-release is strongly encouraged throughout the upper river, helping sustain this extraordinary wild fishery for generations to come. A valid Colorado fishing license is required. If it's your first time on this stretch, a half-day with a local guide from Colorado Fly Fishing Guides in Leadville is well worth it.
