Summary
Designed by Scanlon & Associates, this earth dam stands at a height of 9.5 feet and has a hydraulic height of 8.6 feet. With a storage capacity of 234 acre-feet, this dam plays a crucial role in managing stormwater runoff and protecting the surrounding areas from flooding.
Owned and regulated by the local government, the Se Storm Drainage Detention Dam is inspected regularly to ensure its structural integrity and functionality. Despite being assessed as in fair condition during the last inspection in January 2019, the dam is classified as having a significant hazard potential, emphasizing the importance of continuous monitoring and maintenance. With a moderate risk rating, measures for risk management and emergency response preparedness are essential to safeguard the community in the event of a flood.
As part of the flood risk reduction infrastructure in Artesia, New Mexico, the Se Storm Drainage Detention Dam serves as a critical component in the overall water resource management strategy for the area. Its location on the Pecos River tributary and its uncontrolled spillway design with a width of 118 feet reflect the engineering considerations made to handle peak discharges of up to 2840 cubic feet per second. Climate enthusiasts and water resource experts alike can appreciate the role this dam plays in protecting the local community and environment from 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.
