Summary
Built in 1988, this earth dam stands at 15 feet tall and stretches 150 feet in length, with a storage capacity of 80 acre-feet. The dam serves a low hazard potential and has not been rated for its condition assessment.
Managed by the South Dakota Department of Environment and Natural Resources (DENR), the McCook Country Club Dam is regulated, permitted, inspected, and enforced by the state. Despite being a private structure, it meets state jurisdiction requirements and is part of the state's water resource management initiatives. With a maximum discharge capacity of 754 cubic feet per second, the dam plays a crucial role in flood control and water storage in the region.
Although lacking specific design and purpose details, the McCook Country Club Dam remains an essential component of the water infrastructure in McCook County. With its strategic location and capacity, the dam contributes to the overall management of water resources and climate resilience in the area. As water resource and climate enthusiasts, understanding the significance of structures like the McCook Country Club Dam is crucial for sustainable water management practices.

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.
