Summary
Built in 1958, this dam on the TR-Bad River stands at a height of 49 feet and has a storage capacity of 53 acre-feet. The dam spans 419 feet in length and has a maximum discharge rate of 1260 cubic feet per second. Despite its age, Herman #7 is considered to have a low hazard potential and is currently rated as "Not Rated" in terms of its condition assessment.
Managed by the Natural Resources Conservation Service, Herman #7 is regulated by the South Dakota Department of Environment and Natural Resources. The dam is regularly inspected, permitted, and enforced to ensure its safety and compliance with state regulations. While the dam has not been assessed for its emergency action plan or risk management measures, it remains a crucial structure for water resource management in the area.
With its strategic location and role in controlling water flow on the Bad River, Herman #7 serves as a vital infrastructure for the community. As water resource and climate enthusiasts, understanding the design, construction, and maintenance of dams like Herman #7 is essential for sustainable water management practices in the region.

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.
