Built in 1946, this earth dam stands at 41 feet high with a hydraulic height of 30 feet, creating a storage capacity of 721 acre-feet. The dam spans 362 feet in length and has a spillway width of 200 feet, designed as an uncontrolled spillway to manage a maximum discharge of 23,000 cubic feet per second.
Managed by the Office of the State Engineer, Fenton Lake Dam is in fair condition with a high hazard potential. The dam's last inspection in June 2020 revealed its moderate risk level and its emergency action plan was last revised in January 2016. Despite its age, Fenton Lake Dam continues to provide a vital recreational and environmental resource for the surrounding area, contributing to the conservation of the Rio Cebolla river ecosystem and offering opportunities for outdoor enthusiasts to enjoy its serene waters and scenic surroundings. With ongoing state regulation and inspection, Fenton Lake Dam remains a key component of water resource management in New Mexico.
