Summary
Built in 1968, this dam stands at a height of 25 feet and has a length of 455 feet, providing a storage capacity of 51 acre-feet. Situated on the TR Little White River, this dam is regulated by the South Dakota Department of Environment and Natural Resources (DENR) and undergoes regular inspections, enforcement, and permitting processes to ensure its safety and compliance with state regulations.
Despite being classified as low hazard potential with a condition assessment of "Not Rated," Krogman Louie No.1 plays a crucial role in water resource management and flood control for the surrounding area. With a maximum discharge capacity of 192 cubic feet per second, this dam serves as a vital infrastructure for mitigating potential flooding events and protecting downstream communities. Managed by the Natural Resources Conservation Service, this dam exemplifies the importance of maintaining and regulating water resources to ensure both human safety and environmental sustainability.
As an integral part of the St. Paul District's water infrastructure, Krogman Louie No.1 highlights the collaboration between private owners, state agencies, and federal designers in managing and maintaining critical water resources. With its historical significance dating back to the late 1960s, this dam continues to serve its primary purpose of water storage and flood control, contributing to the overall resilience of the local ecosystem and communities. As water resource and climate enthusiasts, the preservation and proper management of structures like Krogman Louie No.1 are essential for adapting to changing climate patterns and ensuring the long-term sustainability of our valuable water reserves.

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.
