Rio Chama below Abiquiu Dam Fishing Guides and Conditions, New Mexico

About the Rio Chama below Abiquiu Dam

The Rio Chama below Abiquiu Dam is a tailwater in high desert canyon country northwest of Santa Fe, running from the dam down toward the Rio Grande confluence at Espanola. The reach immediately below the dam holds trout year-round because releases pull cooler water from the reservoir, and the surrounding landscape of red sandstone and cottonwood bottom is some of the most photographed in New Mexico. The USGS gauge below Abiquiu Dam reads stage and discharge, and on this river the discharge number is the whole story.

Releases here are managed for irrigation delivery, flood control and downstream water rights rather than for fishing, and they change substantially through the year. Low winter and early spring flows in the low hundreds of cubic feet per second make the river wadeable and the fish accessible. Summer irrigation releases can push flows into the thousands, which turns the reach into a high-volume float and largely ends practical wade fishing until the water comes back down.

Rainbow trout are stocked and supplemented by holdover fish that grow well on a good invertebrate base, and wild brown trout are present through the reach and reach respectable size. Northern pike have established themselves in the system and are caught by trout anglers often enough to be worth mentioning. Channel catfish occupy the warmer lower water toward the confluence.

Fishing strategy follows the gauge more closely here than on almost any other New Mexico water. Check the release before driving, because a river that fished perfectly last week can be unrecognizable today. The upper reach above the reservoir through the Chama Canyon wilderness is a separate and celebrated float fishery under its own permit system, and should not be confused with this tailwater. Public access below the dam is good but scattered.

Seasons

Spring: often the best wading of the year before irrigation season begins, with moderate flows, baetis hatches and willing rainbows through March and April.
Summer: high irrigation releases dominate. The reach becomes a float rather than a wade, and fishing quality depends entirely on where the release is set week to week.
Fall: flows drop back as irrigation demand ends, and September through November usually gives the most consistent wade fishing and the best brown trout activity ahead of spawning.
Winter: low, clear, cold releases and very light pressure. Midge fishing on mild days is productive, and access roads are usually passable but check conditions.
