Summary
Constructed in 1958 by the Natural Resources Conservation Service, this earth dam stands at a height of 30 feet and stretches 774 feet in length. With a storage capacity of 73 acre-feet, it serves the purpose of water resource management in the region.
Despite being classified as low hazard potential and not yet rated for its condition assessment, Herman #4 is regulated by the South Dakota Department of Environment and Natural Resources. The dam has state jurisdiction and is subject to permitting, inspection, and enforcement by the state regulatory agency. Its location in Jones County, South Dakota, adds to the importance of monitoring and maintaining this structure to ensure the safety of surrounding communities and the integrity of the water resource it manages.
Although specific details on its purposes and operations are limited, the data on Herman #4 highlights the essential role it plays in managing water resources along the TR-Bad River. As a focal point for water enthusiasts and climate advocates, understanding the regulatory framework and structural aspects of this dam underscores the significance of sustainable water management practices in South Dakota.

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.
