About the Conchas Lake
Conchas Lake sits where the Conchas River meets the Canadian in northeastern New Mexico, a long impoundment behind Conchas Dam in San Miguel County with red rock bluffs, juniper and open llano around it. It is one of the larger lakes in a state that does not have many, and it has been a fishing destination since the dam was completed in the late nineteen thirties. The lake runs in two main arms that meet near the dam, and the shoreline is long and broken enough that there is almost always somewhere out of the wind.
Walleye are the headline fish and the reason a good share of the boats are on the water. They spawn on the rocky points and windswept shorelines in early spring and spread into deeper structure as the year warms, and the lake has produced them consistently for decades. White bass are the other mainstay, running in schools that can be located by watching for surface activity on a summer evening and then followed for as long as they stay up.
Largemouth and smallmouth bass both do well here, smallmouth on the rock and largemouth in the brush and the back ends of the arms when the lake is up. Channel and flathead catfish are abundant and grow large in a reservoir with this much forage. Crappie fluctuate with water level and available cover, and in a good year they are worth targeting around the standing timber in the upper arms.
Water level is the single thing to check before making the drive. Conchas is a storage reservoir on a plains river and it swings widely between wet and dry cycles, which moves ramps in and out of service and changes where fish hold from one season to the next. The gauge at the dam reads lake stage rather than temperature, so plan launches around the current level and rely on boat electronics for water temperature.

Seasons
Spring: the strongest window, with walleye spawning on the rock and white bass beginning to school.
Summer: hot and often windy, with fish deep by day and good evening surface activity from white bass.
Fall: cooling water brings walleye and bass back onto the points for a second reliable stretch.
Winter: cold and quiet, with limited boat traffic and fish holding deep near the dam.
