Summary
5, also known as the Rodey Arroyo Floodwater Retarding Structure, is a crucial flood risk reduction infrastructure located in Doña Ana, New Mexico. The dam, completed in 1958 by the USDA NRCS, stands at 36 feet tall and spans a length of 340 feet along the Rodey Arroyo. With a storage capacity of 255 acre-feet and a drainage area of 2.38 square miles, the dam plays a vital role in managing floodwaters and protecting the surrounding area from potential inundation.
Despite its importance in flood risk reduction, Hatch Valley Arroyos Dam No. 5 is currently assessed to be in poor condition with a high hazard potential. The last inspection in January 2017 revealed the need for maintenance and potential upgrades to ensure the dam's structural integrity and operational efficiency. With a moderate risk rating of 3, there is a pressing need for risk management measures to be implemented to mitigate potential hazards and safeguard the surrounding communities in the event of an emergency. As a state-regulated structure under the jurisdiction of the Office of the State Engineer, ongoing assessments and enforcement are essential to ensure the dam's continued effectiveness in flood control and water resource management in the region.
In light of its critical role in flood risk reduction and water resource management, the condition and maintenance of Hatch Valley Arroyos Dam No. 5 are of utmost importance. With the involvement of state regulatory agencies and the need for risk management measures, it is essential to prioritize the upkeep and potential upgrades of this key infrastructure to ensure the safety and well-being of the communities it serves. As climate change continues to impact water resources and weather patterns, the resilience and functionality of dams like Hatch Valley Arroyos Dam No. 5 are vital in adapting to changing conditions and mitigating the risks associated with extreme weather events.

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.
