Summary

Built in 1940, this earthen dam stands at a height of 14 feet and stretches 500 feet in length. It serves the primary purpose of regulating water flow along the TR-BAD River, with a storage capacity of 105 acre-feet and a maximum discharge of 1300 cubic feet per second.

Despite its age, Temple No.1 has been deemed to have a low hazard potential and is currently in a "Not Rated" condition assessment status. The South Dakota Department of Environment and Natural Resources regulates and inspects the dam regularly to ensure its safety and compliance with state standards. While there is no associated emergency action plan in place yet, the dam's overall risk management measures and guidelines are under review for potential enhancements.

Overall, Temple No.1 plays a crucial role in water resource management in the region and highlights the importance of private ownership in maintaining and regulating critical infrastructure. As water resource and climate enthusiasts, it is essential to monitor and support efforts to ensure the safety and sustainability of dams like Temple No.1 for the benefit of both local communities and the surrounding environment.

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.
