Alto Lake Dam, located in Ruidoso, New Mexico, is a crucial water supply structure owned by the local government. Completed in 1965, this Earth-type dam stands at a height of 51 feet and has a maximum storage capacity of 449 acre-feet. The dam primarily serves the purpose of water supply, with a normal storage capacity of 299.7 acre-feet and a surface area of 15.4 acres.

Despite its important role in water management, Alto Lake Dam has been assessed to have a high hazard potential and poor condition, as of the last inspection in April 2019. The dam's spillway is uncontrolled, with a width of 20 feet, and it is situated on Eagle Creek. In case of emergencies, the dam's Emergency Action Plan (EAP) preparedness and risk management measures are currently unclear, raising concerns about the dam's ability to withstand potential hazards.

Given its moderate risk assessment and the need for improved maintenance and emergency preparedness, Alto Lake Dam presents a critical area for further evaluation and potential upgrades to ensure the safety and reliability of water resources in the region. Water resource and climate enthusiasts may find this dam's current condition and risk factors particularly intriguing for ongoing monitoring and potential mitigation efforts.
