Summary
2, also known as North Salem #2, is a crucial structure owned by the local government in Doña Ana, New Mexico. Constructed in 1957 by the USDA NRCS, this earth dam serves the primary purpose of flood risk reduction along the North Salem Arroyo. With a height of 33 feet and a length of 1793 feet, it provides a storage capacity of 124 acre-feet and can handle a maximum discharge of 5340 cubic feet per second.
Despite its importance in mitigating flood risks, the dam's condition assessment in 2019 rated it as poor with a high hazard potential, highlighting the need for immediate attention and maintenance. The emergency action plan and risk management measures for Hatch Valley Arroyo Dam No. 2 are currently under review, reflecting the ongoing efforts to ensure the safety and resilience of this critical water resource infrastructure. As climate change continues to impact water resources, the effective management and upkeep of dams like this one are essential in safeguarding communities and ecosystems from potential disasters.

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.
