Summary
The dam stands at a height of 20 feet and has a storage capacity of 66 acre-feet, with a normal storage level of 32 acre-feet. Situated on Cut Meat Creek-TR, the dam serves the purpose of water resource management in the region and is regulated by the South Dakota Department of Environment and Natural Resources.
Although Krogman Dam is classified as having a low hazard potential and a moderate risk assessment, it is not currently rated for its condition. The dam features an uncontrolled spillway with a width of 70 feet and does not have any outlet gates. Despite its relatively low hazard potential, the dam plays a crucial role in the local water resource infrastructure and contributes to the overall management of water supply and flood control in the area.
Enthusiasts of water resources and climate will find Krogman Dam to be an intriguing structure, with its unique design and purpose. As a key component of the water management system in Mellette, South Dakota, the dam stands as a testament to the importance of sustainable water resource development and the role of private entities in ensuring the safety and efficiency of water infrastructure. With its completion in 2000 and ongoing regulatory oversight, Krogman Dam remains a vital asset in the region's efforts to manage water resources effectively in the face of changing climate patterns.

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.
