Weatherly Reservoir Dam, located in Union County, New Mexico, was completed in 1914 for the primary purpose of irrigation.


Summary

The dam, standing at a height of 32 feet and with a length of 1382 feet, holds a maximum storage capacity of 1083 acre-feet of water from the Corrumpa Creek-TR. Despite its low hazard potential, the dam's condition assessment was rated as poor during its last inspection in 2014.

With the Office of the State Engineer overseeing its regulation, inspection, and enforcement, Weatherly Reservoir Dam plays a crucial role in water resource management in the region. The dam has a moderate risk factor of 3, but has not had an Emergency Action Plan (EAP) prepared or updated in recent years. Given its significance for irrigation and its location in a semi-arid climate, ensuring the structural integrity and proper maintenance of the dam is essential for both water supply and climate resilience efforts in the area.

Weatherly Reservoir Dam serves as a vital water resource infrastructure in New Mexico, contributing to agricultural activities and water supply reliability in the region. While the dam's structural height and volume are substantial, its condition assessment and risk factor suggest the need for closer monitoring and potential maintenance. As water resource and climate enthusiasts, understanding the role of dams like Weatherly Reservoir in managing water scarcity and ensuring sustainable water use is crucial for promoting resilience in the face of changing climate patterns.

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.
