The Rio Chama is the river you fish when the San Juan is a zoo, and the one that quietly gives up the biggest brown trout in New Mexico. The stretch below El Vado Dam is the draw: cold bottom-release water holds between roughly 40 and 55 degrees all year, and it grows browns that push past 20 inches with real regularity — the state-record brown came out of this water. It's a medium-sized river over a gravel-and-cobble bottom, not the tiny spring creek some people expect, and it fishes like a technical tailwater: small bugs, good drifts, and fish that have seen flies before.

What makes the Chama worth the drive is that it's really several rivers stacked on one drainage, so something is usually fishing well. The El Vado tailwater is the trophy water and wades cleanly at 300-800 CFS, with a designated three-mile catch-and-release stretch starting about a mile and a quarter below the dam. Downstream, the Rio Chama Wildlife Area cuts through a volcanic gorge — pocket water, deep pools, undercut banks, and a rock bottom that will test your ankles, but trout densities run well over a thousand fish per mile. Below that, the Wild & Scenic canyon from Cooper's El Vado Ranch down to Big Eddy is a multi-day float through red-rock wilderness with Class II-III water, more of a raft-and-camp trip than a day of wading and requiring a BLM permit for overnights. Way at the bottom, the short tailwater below Abiquiu Dam is the mellow winter option — gentle Class I flows and mostly stocked and holdover rainbows, with less pressure than El Vado.

The catch, as always with a dam river, is the dam. El Vado releases swing hard for irrigation and storage, so the same run that fished beautifully at 400 CFS can be blown out past 2,500 during the May-June runoff push, and Abiquiu turns off-color when releases jump. Check the gauge below the dam before you commit to the drive — this is not a river to show up at blind. Most anglers stage out of Santa Fe, about two hours south, or the little village of Chama up north, and the same Santa Fe shops that run the San Juan handle Chama trips and shuttles.

Species

  • Brown Trout
    Primary · Sep-Nov · 12-20"+

    The dominant fish and the reason to come. The El Vado tailwater grows the state's largest browns — wild, self-sustaining fish to 24 inches show up every year. The fall pre-spawn streamer bite is the best window for a genuine trophy; the rest of the year they eat small nymphs deep and hold along cut banks and in the gorge's undercut pockets.

  • Rainbow Trout
    Common · Apr-Jun, winter · 10-16"

    Wild holdovers scattered through the gorge and freestone water; the reach below Abiquiu Dam is mostly stocked and holdover rainbows and fishes best in winter on midge rigs. Reliable on baetis and midges in the tailwaters, and a good target when the browns get moody.

  • Kokanee Salmon
    Seasonal · Oct-Dec · 12-18"

    Not a fly target, but part of the fishery: kokanee drop out of El Vado Lake in the fall, and a special snagging season runs Oct 1 - Dec 31 from the lake down to the western Rio Chama Wildlife Area boundary. Worth knowing about if you see people fishing them and want to understand the closure lines.

Ideal wading flow300–800 CFS
Blow-out>2,000 CFS
Ideal water temp48–58°F

Fall (brown pre-spawn aggression, BWO, October caddis) and spring (BWO, pre-runoff) are prime. Winter is the sleeper — the below-Abiquiu tailwater and year-round midge fishing stay productive when everything else is frozen. Summer is dam-dependent: excellent once runoff drops off, tough during the May-June release peak. The El Vado tailwater stays cold (40-55 degrees) year-round, so temperature is rarely the limiter there — flow is.

Sections

4 sections on this river

El Vado Tailwater

WadeBrown Trout · Rainbow Trout

The trophy water. Cold bottom-release flows out of El Vado Dam hold 40-55 degrees year-round over a gravel-and-cobble bottom, and the brown trout here grow bigger than anywhere else in New Mexico — the state record came from this reach, and fish past 20 inches show up every season. A designated three-mile catch-and-release, artificial-only stretch begins about 1.3 miles below the dam. It fishes like a technical tailwater: small nymphs and good drifts at 300-800 CFS, with a BWO and midge dry-fly game on overcast days. Parking areas with vault toilets and foot trails line the reach.

Best for: Trophy brown trout on nymphs and streamers, plus technical BWO and midge dry-fly work for rainbow trout. Fall pre-spawn is the best shot at a genuine wall-hanger brown.

Rio Chama Wildlife Area

WadeBrown Trout · Rainbow Trout

Below the tailwater the river drops into a volcanic gorge — pocket water, deep pools, undercut banks, and current fast enough to demand good footing on slick rock. It's some of the most productive public-access trout water in the state, with density estimates well over a thousand trout per mile. Wild brown trout hold in the pockets and along the cut banks, mixed with holdover rainbow trout. Nymphing the pocket water and swinging or stripping streamers through the deeper slots is the game. Multiple parking areas with trails drop anglers to the river near the Rio Brazos confluence.

Best for: Wild brown trout and holdover rainbow trout on nymphs and streamers in fast pocket water. High fish density; technical wading.

Wild & Scenic Canyon (Cooper's to Big Eddy)

FloatBrown Trout · Rainbow Trout

A wilderness float through red-rock canyon — roughly 24 miles of Class II-III water from the Cooper's El Vado Ranch put-in down to the Big Eddy take-out above Abiquiu Reservoir. This is a raft-and-camp trip more than a day of wading, and overnight floats need a BLM permit. The fishing is opportunistic: streamers and attractor dries thrown from the raft for brown trout, with pull-overs to wade the best runs. The draw is the scenery, the wildlife, and the near-total lack of pressure.

Best for: Multi-day float-and-camp trips for brown trout on streamers and attractor dries. Wilderness solitude; whitewater and shuttle logistics required.

Below Abiquiu Dam

WadeBrown Trout · Rainbow Trout · Northern Pike

The mellow winter option: about five miles of gentle Class I tailwater through desert canyon directly below Abiquiu Dam. The water is mostly stocked and holdover rainbow trout plus a few brown trout, and there's good public access on public land right below the dam. It fishes best in winter on midge and nymph rigs when the rest of the drainage is frozen and pressure is light. The one catch is that it goes off-color and fishes poorly when Abiquiu releases spike, so check the gauge first.

Best for: Beginner-friendly winter fishing for stocked and holdover rainbow trout on midges and nymph rigs. Easy wading, low pressure.

Regulations

Current fishing rules and restrictions

Special Trout Water on the Rio Chama, with a three-mile catch-and-release, artificial-only stretch below El Vado Dam and a special kokanee snagging season in the fall. A New Mexico fishing license is required, and overnight Wild & Scenic canyon floats need a BLM permit.

  • Catch-and-release, artificial flies and lures only on the 3-mile stretch beginning about 1.3 miles below El Vado Dam (from roughly a quarter mile below Cooper's, where the gauging cable crosses, down to the Rio Nutrias/Canyon confluence)
  • Special Trout Waters generally require single, barbless hooks; no chumming or baitfish
  • Special kokanee salmon snagging season Oct 1 - Dec 31, from El Vado Lake downstream to the western boundary of the Rio Chama Wildlife Area
  • A New Mexico fishing license is required everywhere
  • Multi-day floats through the Wild & Scenic canyon require a BLM permit

Regulations reflect the 2025-2026 New Mexico cold-water rules — verify current rules before fishing, especially the posted boundaries of the catch-and-release stretch and the kokanee snagging closure lines.

Access & Logistics

Getting there, fly shops, and lodging

Getting There

Chama, NM (upper river); Abiquiu, NM (lower tailwater)

2 hrs from Santa Fe, 2.5 hrs from Albuquerque, 45 min from Chama to El Vado

Fly Shops

Camping & Lodging

Cooper's El Vado Ranch offers cabins plus the private put-in and shuttle for canyon floats. El Vado Lake and Heron Lake State Parks have campgrounds near the upper river; primitive BLM camping lines the Wild & Scenic canyon (permit required for overnight floats). Santa Fe and Abiquiu have full lodging.

El Vado releases swing hard for irrigation — always check the USGS gauge below the dam before driving in. The volcanic rock in the Rio Chama Wildlife Area gorge makes for treacherous wading; felt or studded boots and a wading staff help. The desert canyons get windy, so plan technical dry-fly work around the calmer morning hours.

North-Central New Mexico

Costilla CreekNM

A small high-meadow tailwater in the Valle Vidal north of Taos holding one of the last stronghold populations of pure Rio Grande cutthroat — willing 8-to-12-inch natives on dry-dropper and hoppers, wade-only, and closed until July 1 to protect the spring spawn.

Pecos RiverNM

The trout stream most New Mexicans learned to fly fish on — a small, cold, wadeable snowmelt freestone that drops out of the Pecos Wilderness along NM 63 past Terrero and Cowles. Roadside stocked rainbows and wild stream-bred browns down low, a legendary late-June salmonfly hatch through the canyon, and native Rio Grande cutthroat in the walk-in wilderness headwaters.

Red RiverNM

An Enchanted Circle trout stream that fishes as two rivers under one name — a heavily stocked, roadside rainbow run through the ski town up top, and a wild, spring-fed brown-trout canyon down low that stays cold and open through winter as it drops into the Rio Grande gorge below Questa.

Rio GrandeNM

A big basalt-canyon freestone in the gorge north of Taos — hike-in pocket water for wild browns and native Rio Grande cutthroat that blows out on Colorado snowmelt in May and June and comes alive on caddis and big attractor dries in late summer and fall.

Rio PuebloNM

A small roadside mountain stream along NM-518 near Peñasco — pocket water and plunge pools holding stocked rainbows, wild browns, and native Rio Grande cutthroat in the colder headwaters. Not to be confused with the Rio Pueblo de Taos to the north.

Other regions

Cimarron RiverNM

A small, cold canyon tailwater below Eagle Nest Lake that fishes like a mountain freestone — granite-walled pocket water along US-64 through Cimarron Canyon State Park, packed with wild brown trout (roughly 4,000 per mile) that reward a short cast and a stealthy approach over distance.

Gila RiverNM

New Mexico's wildest trout water — small, tumbling freestone forks in the Gila Wilderness holding native Gila trout, the copper-and-gold rarity you fish for under a free state permit after a long dirt road and a longer walk. Fish run small and the season is short; late September through November is the window.

Jemez RiverNM

A tangle of small freestone trout streams draining the south side of the Valles Caldera — roadside wild-brown water on the Jemez mainstem, East Fork, Rio San Antonio, and Rio Guadalupe, most of it Special Trout Water, with a famous Guadalupe salmonfly hatch in late spring.

San Juan RiverNM

A high-desert tailwater below Navajo Dam where big rainbows and browns key on year-round midges, baetis, and annelids. The Quality Waters in the first few miles fish technical 6X-7X to size 22-26 nymphs; below that the bait water opens up for float and easier wading.
