Summary
Constructed in 1959 by the Natural Resources Conservation Service, this dam stands at a height of 38 feet and has a storage capacity of 31 acre-feet. With a low hazard potential, this dam has not been rated for its condition assessment, but it is regulated and inspected by the South Dakota Department of Environment and Natural Resources.
Despite its age, Herman #5 remains a vital structure for water resource management in the area, providing necessary storage and flood control along the Bad River. While it lacks detailed information on spillways, locks, and other associated structures, the dam has a maximum discharge capacity of 504 cubic feet per second. The dam is also situated within the St. Paul District of the US Army Corps of Engineers jurisdiction, ensuring proper oversight and maintenance.
As a key element of the water infrastructure in Jones County, South Dakota, Herman #5 plays a crucial role in mitigating flood risks and ensuring water availability for agricultural and municipal needs. Although the dam's condition assessment is currently not rated, its low hazard potential suggests that it remains a safe and reliable structure. With regular inspections and enforcement by state regulatory agencies, Herman #5 continues to serve its purpose effectively in managing and controlling water resources 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.
