Summary
Standing at a height of 29 feet with a length of 639 feet, this dam serves the primary purpose of water resource management along the TR-Bad River. With a maximum storage capacity of 51 acre-feet and a normal storage of 32 acre-feet, Herman #8 plays a crucial role in regulating water flow and mitigating potential flood risks in the area.
Managed by the DENR and regulated by the state of South Dakota, Herman #8 has undergone various inspections to ensure its structural integrity and functionality. Despite being classified as having a low hazard potential and not yet rated for its condition assessment, Herman #8 remains a key component in the overall water resource infrastructure of the region. With an emergency action plan yet to be prepared and limited risk assessment measures in place, there is a need for continued monitoring and maintenance to uphold the safety and efficiency of this essential water management structure.
Supported by federal funding and designed by the Natural Resources Conservation Service, Herman #8 stands as a testament to the collaborative efforts in maintaining water resource sustainability and climate resilience in the face of changing environmental conditions. As water resource and climate enthusiasts, staying informed about the status and management of dams like Herman #8 is crucial for understanding the interconnectedness of water systems and the importance of proactive conservation efforts for a more sustainable 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.
