Summary
Built in 1934 by the Bureau of Reclamation, it serves primarily for irrigation purposes, with additional functions for recreation and water supply. The dam stands at a height of 230 feet, with a hydraulic height of 167 feet, and a length of 1326 feet, creating a reservoir with a normal storage capacity of 196,250 acre-feet and a maximum capacity of 209,330 acre-feet. The dam has a controlled spillway and a high hazard potential, with a very high risk assessment rating.
The El Vado dam is a significant structure in the region, providing vital water resources for agricultural purposes and recreational activities. Its location in the picturesque surroundings of Rio Arriba County makes it a popular spot for water enthusiasts and nature lovers. The dam's operations and regulatory oversight are managed by the Bureau of Reclamation, ensuring its safe and efficient functioning. Despite its age, El Vado continues to play a crucial role in water management and conservation efforts in the area, highlighting the importance of sustainable water resource management in the face of climate change challenges.
As climate change impacts water resources worldwide, the role of dams like El Vado becomes even more critical in ensuring water security for communities and ecosystems. The risk assessment for El Vado indicates a high potential for hazards, underscoring the need for effective risk management measures and emergency preparedness. With its rich history and continued relevance in water management, El Vado stands as a symbol of resilience and adaptation in the face of evolving climatic conditions, serving as a reminder of the intricate relationship between water resources, climate, and human activities.

Dam Data Reference
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.
