About this water

A tailwater river below Eagle Nest Lake through Cimarron Canyon, Colfax County, New Mexico.

Fishing Cimarron River: the full guide

A small river with steady water

The Cimarron River flows out of Eagle Nest Lake through Cimarron Canyon in northern New Mexico, a tailwater whose releases keep it cold and fishable when nearby freestone streams warm. Wild brown trout dominate, with stocked rainbows added, in a canyon of granite palisades that the state protects as a wildlife area.

Wild browns in tight water

The river is small: fifteen to twenty-five feet wide in places, with plunge pools, undercut banks and pocket water. Short casts, careful approaches and small flies are the requirements, and the wild browns reward anglers who fish quietly. Special regulations apply in the canyon, including artificial-only water: check current rules.

Flows and the seasons

Releases from Eagle Nest govern the river and keep summer flows workable, though irrigation demands can drop it low. Spring and fall are the strongest seasons, with summer fishing viable early and late. Winter access depends on snow on Highway 64, which follows the canyon closely.

Colfax County logistics

Cimarron Canyon State Park and the Colin Neblett Wildlife Area provide access with campgrounds and pullouts along Highway 64 between Eagle Nest and Cimarron. The village of Cimarron sits at the canyon mouth, with Philmont Scout Ranch nearby. Eagle Nest Lake above adds a stillwater option in the same drive.

Common questions
