Summary
2, also known as Pena Blanca Dam, is a key structure in flood risk reduction efforts in Mesquite, New Mexico. Owned by the local government and regulated by the Office of the State Engineer, this earth dam stands at a height of 55 feet and spans 2740 feet in length. Completed in 1965 by the USDA NRCS, this dam plays a crucial role in managing the flow of the Pena Blanca Arroyo.
With a high hazard potential and poor condition assessment, Apache Brazito Mesquite Dam No. 2 requires regular inspections and maintenance to ensure its structural integrity. The dam features an uncontrolled spillway with a width of 900 feet and other controlled outlet gates. Despite its moderate risk assessment rating, this dam presents challenges that must be addressed to mitigate potential hazards and ensure the safety of surrounding communities in the event of a flood.
For water resource and climate enthusiasts, Apache Brazito Mesquite Dam No. 2 serves as a fascinating case study in dam infrastructure and flood risk management. As efforts continue to maintain and improve this essential structure, it highlights the importance of proactive measures in safeguarding water resources and communities from the impacts of extreme weather events.

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.
