Located in Los Lunas, New Mexico, the Los Morros Business Park Offsite Drainage Dam 5 is a crucial element in flood risk reduction along the Los Lunas Arroyo.


Summary

Built in 2009 by Easterling Consultants LLC, this earth dam stands at 15 feet high and spans 1250 feet in length. With a storage capacity of 101.7 acre-feet, this dam plays a vital role in protecting the surrounding area from potential flooding events.

Managed by the Office of the State Engineer in New Mexico, this dam has a low hazard potential and is deemed to be in satisfactory condition as of the last assessment in 2013. Equipped with an uncontrolled spillway and needle outlet gates, the dam is designed to handle a maximum discharge of 1122 cubic feet per second. Despite its moderate risk assessment rating, the dam's risk management measures and emergency action plans are not explicitly outlined, raising questions about its preparedness for potential disasters.

As a part of the local government's infrastructure, the Los Morros Business Park Offsite Drainage Dam 5 serves as a critical component in safeguarding the community against flood-related risks. With its strategic location and design features, this dam stands as a testament to effective water resource management and climate resilience efforts in the region.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
