Summary
With a maximum storage capacity of 152 acre-feet and a normal storage of 65 acre-feet, this dam serves multiple purposes including flood control, irrigation, and water supply for the region. The dam stands at a height of 25 feet and spans 510 feet in length, with a maximum discharge capacity of 960 cubic feet per second.
Owned and regulated by the state of South Dakota, King Dam is inspected regularly to ensure its structural integrity and safety. With a low hazard potential and a condition assessment currently not rated, the dam meets state jurisdiction requirements for permitting, inspection, and enforcement. Despite its relatively small drainage area of 2 square miles, King Dam plays a crucial role in managing water resources in the region and mitigating potential risks associated with flooding and water scarcity.
For water resource and climate enthusiasts, King Dam represents a vital infrastructure asset in South Dakota's water management system. With the potential to impact local ecosystems and communities, the dam's design and operation are essential considerations in addressing the challenges of climate change and sustainable water resource management. As efforts continue to enhance the dam's emergency action plan and risk assessment measures, King Dam remains a key player in safeguarding water security and resilience in the face of changing environmental conditions.

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.
