Summary
With a height of 38.7 feet and a length of 1873 feet, this earth dam provides a critical function in managing water flow and mitigating potential flood damage in the area. The dam has a storage capacity of 249.9 acre-feet and a spillway width of 155 feet to handle maximum discharges of up to 12,445 cubic feet per second.
Managed by the local government of Albuquerque, Raymac Detention Dam is regulated by the Office of the State Engineer in New Mexico. The dam has been assessed as being in satisfactory condition, with a high hazard potential due to its location and purpose. Regular inspections are conducted every five years to ensure its continued effectiveness in flood risk reduction. While the dam poses a moderate risk, appropriate risk management measures are in place to address any potential issues and ensure the safety of the surrounding community and environment. For water resource and climate enthusiasts, Raymac Detention Dam stands as a testament to effective engineering and management practices in safeguarding against the impacts of 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.
