Summary
Completed in 1951, this earth dam stands at a height of 17.8 feet with a structural height of 25 feet and a length of 6774 feet. With a storage capacity of 720 acre-feet and a spillway width of 100 feet, the dam plays a crucial role in managing water flow and reducing potential hazards in the region.
Despite its significance in flood control, the Mclead Flood Control Dam is currently assessed as being in poor condition, with a high hazard potential. The dam is regulated and inspected by the Office of the State Engineer in New Mexico, ensuring its compliance with state regulations and enforcement. However, with a risk assessment rating of moderate and an inspection frequency of 5 years, there is a pressing need for improved risk management measures and potential rehabilitation to enhance the dam's effectiveness in safeguarding the surrounding area from flood events.
As a focal point for water resource and climate enthusiasts, the Mclead Flood Control Dam stands as a testament to the ongoing efforts to mitigate flood risks and protect communities in Doña Ana County. With its historical significance and critical role in water management, the dam serves as a reminder of the importance of infrastructure resilience in the face of changing climate patterns and increasing water-related challenges.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
