Colorado

Colorado's designation of Gold Medal trout waters has become a benchmark of quality recognized by anglers worldwide, and the state earns that reputation with a remarkable collection of tailwaters, freestone rivers, and mountain streams distributed across some of the highest terrain in the Lower 48. The South Platte River system, from Cheesman Canyon's technical spring creek-like currents to the wide riffles of Deckers, produces trout of extraordinary size and selectivity that will test even the most accomplished nymph fisherman. Meanwhile, the Frying Pan River below Ruedi Reservoir has earned a near-mythical reputation for trophy rainbows that sip tiny midges in gin-clear tailwater flows.

The Arkansas River corridor from Leadville to Canon City offers one of the longest stretches of Gold Medal water in the state, with brown trout populations that thrive in the freestone pocket water and deep runs carved through high-desert canyon walls. The Colorado, Eagle, and Roaring Fork rivers on the Western Slope provide exceptional dry fly fishing during summer, when prolific hatches of green drakes, pale morning duns, and caddis bring large trout to the surface in breathtaking Rocky Mountain valleys. For those willing to hike above timberline, Colorado's alpine lakes and streams hold native greenback cutthroat trout in some of the most stunning settings imaginable, with fishing at elevations exceeding twelve thousand feet.

Colorado's proximity to the Denver metropolitan area means that some waters see significant pressure, but the state's vast public lands and extensive network of trails provide access to remote fishing that rivals anything in the West. The Gold Medal program itself, which recognizes waters capable of sustaining at least sixty pounds of trout per acre and at least twelve fish of fourteen inches or larger per acre, ensures that designated stretches receive the management attention necessary to maintain trophy-caliber fisheries. Special regulations on these waters typically include artificial flies and lures only, with reduced bag limits or catch-and-release requirements.

The Colorado fishing calendar begins in earnest with spring midge and blue-winged olive hatches on the tailwaters, building through the runoff period in May and June to peak activity in July and August when terrestrial patterns and attractor dry flies produce explosive surface takes. Fall fishing from September through November is arguably the finest season, with low water, reduced crowds, spawning brown trout aggressively defending their redds, and reliable afternoon hatches of blue-winged olives that can produce the best dry fly fishing of the year.
