Clayton Dam, located in Union, New Mexico, along the CIMARRON RIVER-TR, is a state-regulated structure primarily used for recreation.


Summary

Built in 1955, this earth dam stands at a height of 82 feet and spans a length of 720 feet, with a storage capacity of 6,630 acre-feet and a surface area of 175 acres. Despite its low hazard potential, the dam is rated in fair condition and undergoes inspections every five years to ensure its structural integrity.

The dam features an uncontrolled spillway with a width of 150 feet, capable of handling a maximum discharge of 24,700 cubic feet per second. With its moderate risk assessment rating, Clayton Dam is monitored by the Office of the State Engineer for state permitting, inspection, and enforcement. The surrounding area, including the downstream residence, benefits from the recreational opportunities provided by the dam, making it a valuable asset for water resource and climate enthusiasts interested in the management and conservation of water infrastructure in New Mexico.

Overall, Clayton Dam serves as a vital component of water resource management in the region, offering both recreational opportunities and essential flood control measures along the CIMARRON RIVER-TR. As a state-regulated structure, it represents a collaborative effort between the state and federal agencies to ensure the safety and efficiency of the dam. With its historical significance and ongoing maintenance, Clayton Dam remains a focal point for water resource and climate enthusiasts interested in the sustainable development and conservation of water infrastructure in the state of New Mexico.

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.
