Summary
Built in 1957 by the Natural Resources Conservation Service, this earth dam stands at a height of 22 feet and has a length of 713 feet. With a storage capacity of 71 acre-feet, it serves the primary purpose of water resource management on the TR-Bad River.
Managed and regulated by the South Dakota Department of Environment and Natural Resources, Louder Number 3 has a low hazard potential and has not been rated for its current condition. Despite its age, the dam continues to provide essential water storage and management functions for the local area. It is regularly inspected and maintained to ensure its safety and effectiveness in mitigating potential flood risks on the Bad River.
The dam's location within the St. Paul District and its association with the federal agency indicate its importance in the overall water infrastructure of the region. While currently not designated as a high-risk structure, ongoing monitoring and risk assessment measures are crucial to ensuring the continued safety and reliability of Louder Number 3 for both water resource management and climate resilience in the future.

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.
