Summary

Built in 1910, this gravity dam stands 29 feet tall and spans 183 feet in length, with a storage capacity of 18,200 acre-feet and a maximum discharge rate of 20,400 cubic feet per second. The dam is regulated by the Federal Energy Regulatory Commission, with inspections conducted by the same agency to ensure its safe operation.

With a high hazard potential and a risk assessment rating of "Very High (1)", the Kings Dam poses significant challenges in terms of emergency preparedness and risk management. Despite the lack of available condition assessment data, the dam still plays a crucial role in water resource management and energy production in the region. Its controlled spillway, Tainter gates, and surrounding infrastructure contribute to the overall functionality and safety of the dam.

As water resource and climate enthusiasts, understanding the complexities and risks associated with structures like Kings Dam is essential for promoting sustainable water management practices and mitigating potential hazards. By staying informed and actively engaging in discussions around dam safety and emergency preparedness, enthusiasts can help ensure the continued resilience of water infrastructure in the face of changing climate conditions and increasing water resource demands.

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.
