Summary

Completed in 1978 under the supervision of the DOI BIA, Seama serves a low hazard potential and is currently assessed to be in a condition that is not available. While not regulated by the state, this dam poses minimal risk and does not have a detailed emergency action plan in place.

Despite its simple structure and lack of state jurisdiction, Seama remains an essential component of water resource management in the region. With its primary purpose and specific dam type not listed, Seama stands as a testament to the intricate network of dams and reservoirs that play a crucial role in maintaining water supply and irrigation in New Mexico. Furthermore, as a federally owned and funded structure, Seama provides a glimpse into the diverse landscape of water management agencies in the state.

Although lacking detailed assessments and emergency protocols, Seama's historical significance and functional capacity highlight the intersection of human ingenuity and environmental stewardship in the management of water resources. As climate change continues to impact water availability and quality, structures like Seama serve as vital tools in mitigating the effects of droughts and floods in the region. With ongoing monitoring and potential updates to its risk management measures, Seama represents a blend of past infrastructure development and future 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.
