Summary
Built in 1950, this Earth-type dam stands at a height of 15 feet and has a length of 400 feet, providing a storage capacity of 54 acre-feet. The dam is regulated by the South Dakota Department of Environment and Natural Resources and is inspected, permitted, and enforced by the state agency to ensure its safety and compliance with regulations.
With a low hazard potential and a "Not Rated" condition assessment, Sd Noname 272 serves as a vital structure for water resource management in the area. Its maximum discharge capacity is 600 cubic feet per second, and it plays a crucial role in flood control and water storage. While the dam has not been modified in recent years and its emergency action plan status is unclear, it remains a key component in the region's water infrastructure, contributing to the overall resilience and sustainability of the local water resources.
Managed by a private owner, Sd Noname 272 stands as a testament to the importance of private-public partnerships in maintaining and safeguarding water resources in South Dakota. While the dam's specific purposes and associated structures are not detailed in the data, its role in water management and regulation highlights the collaborative efforts necessary to ensure the protection and sustainability of our valuable water sources in the face of changing climate conditions.

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.
