Summary
The dam, situated on the tributary of Oak Creek, serves the primary purpose of water storage and management. Despite being classified as having a low hazard potential, the dam is regulated by the South Dakota Department of Environment and Natural Resources (DENR) and undergoes regular inspections to ensure its structural integrity and safety.
Managed by a private entity, Krumm Dam plays a crucial role in regulating water flow and storage in the area, with a maximum discharge capacity of 300 cubic feet per second. Although the dam is currently rated as 'Not Rated' in terms of condition assessment, it meets state regulatory standards and is equipped with emergency action plans for effective risk management. With an emphasis on safety and environmental stewardship, Krumm Dam remains a key infrastructure supporting water resource management in the region.
In the event of emergencies or potential risks, the dam has established protocols in place, including updated emergency action plans and contacts. While it is not operated by the US Army Corps of Engineers, Krumm Dam adheres to state regulations and guidelines to ensure its operational efficiency and safety standards. As a vital component of water resource infrastructure in South Dakota, Krumm Dam exemplifies the importance of responsible dam management in mitigating climate impacts and ensuring water security for the surrounding community.

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.
