Summary
With a height of 16 feet and a length of 700 feet, this dam serves as a vital water resource for the area, providing a maximum storage capacity of 60 acre-feet and a normal storage of 25 acre-feet. Despite its low hazard potential, the dam is regulated by the South Dakota Department of Environment and Natural Resources, ensuring that it meets state permitting, inspection, and enforcement requirements.
Managed by a private owner, Sd Noname 184 plays a crucial role in flood control and water supply management in the region. With a maximum discharge capacity of 4000 cubic feet per second, the dam helps mitigate the risk of flooding during heavy precipitation events. Although the condition of the dam is currently not rated, it is essential for the owner to ensure regular inspections and maintenance to uphold its structural integrity and safety standards.
Representing a significant piece of infrastructure in the area, Sd Noname 184 stands as a testament to the importance of water resource management in the face of changing climate patterns. With the support of state regulatory agencies and adherence to safety protocols, this dam continues to serve its purpose effectively, safeguarding the community and environment against potential water-related risks.

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.
