Summary
Completed in 1975, this earth dam stands at a height of 67 feet with a structural height of 85 feet and a length of 15,570 feet. With a storage capacity of 13,200 acre-feet and a surface area of 550 acres, the dam plays a vital role in protecting the surrounding areas from potential flooding events.
Managed by the local government and regulated by the Office of the State Engineer, Las Cruces Dam is subject to regular inspections to ensure its structural integrity and safety. The dam has a high hazard potential but is currently assessed as being in satisfactory condition. With a maximum discharge capacity of 30,400 cubic feet per second, the dam is equipped with an uncontrolled spillway that is 400 feet wide. Despite its moderate risk level, Las Cruces Dam remains a key component of the region's water resource and climate management infrastructure, safeguarding the community against the impacts of extreme weather events.
Named after the city of Las Cruces, this vital flood risk reduction structure plays a crucial role in mitigating the potential impacts of flooding in the area. With a history of effective operation and maintenance, Las Cruces Dam continues to serve as a reliable defense against the threat of inundation, highlighting the importance of proactive water resource management in the face of changing climate conditions.

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.
