Fly Fishing Cimarron River - Below Eagle Nest Dam

Fly fishing Cimarron River below Eagle Nest Dam reveals one of New Mexico's hidden gem tailwater fisheries, offering technical small-stream fishing in the stunning granite canyon setting of Cimarron Canyon State Park. This 10-mile section flows from the base of Eagle Nest Dam downstream through Cimarron Canyon to Ute Park, with the river tumbling through a narrow gorge of towering granite palisades, dense conifer forest, and car-sized boulders that create an endless series of plunge pools, pocket water, and short technical runs. Flows typically range from just 15 to 50 CFS, making this an intimate wade-only fishery where stealth, precision, and light tackle are essential. The cold, consistent dam releases provide temperature stability that supports healthy trout year-round, giving this diminutive river productivity that belies its modest size.

Brown trout and rainbow trout inhabit the canyon, with browns being the dominant species. NMDGF stocks rainbows periodically near campground access points, supplementing a self-sustaining brown trout population. Fish generally range from 10 to 15 inches, with experienced anglers targeting deeper plunge pools and undercut boulder gardens occasionally connecting with browns in the 16- to 20-inch class. A 7.5- to 8.5-foot rod in 2- to 4-weight is the ideal tool, with 9-foot leaders tapered to 5X or 6X tippet standard for the clear tailwater flows.

Midges are the year-round staple, with size 20-26 larvae, pupae, and adults making up a significant portion of the trout diet during winter and early spring. Baetis mayflies provide critical dry fly fishing from March through May and again September through November, with size 18-22 blue-winged olives hatching reliably on cloudy days. Summer brings caddis, small stoneflies, and terrestrial activity — elk hair caddis, small stimulators, and foam ant and beetle patterns produce from July through September. Unlike New Mexico's freestone streams, the Cimarron fishes well during spring runoff when surrounding rivers are blown out, making it an excellent backup destination during the unpredictable spring transition.

Cimarron Canyon State Park provides the access framework. US-64 runs through the canyon between Eagle Nest and Cimarron with multiple pullouts and campgrounds. The Palisades Sills area near the upper end is dramatic and popular, where granite walls close in and the river flows through a narrow, boulder-choked gorge. Maverick and Tolby campgrounds provide additional access downstream. A state parks day-use fee or annual pass is required. The village of Eagle Nest sits at the upper end, the town of Cimarron at the lower end, with Angel Fire just south offering resort accommodations. Doc Thompson's High Country Anglers in nearby Taos/Angel Fire area and Taos Fly Shop (about an hour west) provide flies, gear, and local knowledge. Albuquerque International Sunport (ABQ) is approximately three hours northeast via I-25 and US-64.
