Summary
Built in 1987 by BOHANNON HUSTON, INC., this earth dam stands at a height of 25 feet and stretches 215 feet in length. With a storage capacity of 53.61 acre-feet and a spillway width of 75 feet, the dam plays a crucial role in managing water flow and protecting the surrounding area from potential flooding.
Managed by the Office of the State Engineer in New Mexico, the Martin Arroyo Dam undergoes regular inspections to ensure its structural integrity and safety. Classified with a high hazard potential, the dam is rated as having a satisfactory condition assessment as of December 2019. With a moderate risk assessment score of 3, the dam is equipped with emergency action plans and protocols in place to mitigate any potential risks or emergencies that may arise.
Beyond its functional purpose, the Martin Arroyo Dam serves as a symbol of effective water resource management and climate resilience efforts in the region. With its strategic location in the Sacramento District and its critical role in flood risk reduction, this dam stands as a testament to the importance of infrastructure in safeguarding communities and ecosystems against natural disasters and climate-related challenges.

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.
