Summary
Constructed in 1957, this earth dam stands at a height of 20 feet and spans a length of 520 feet, providing a storage capacity of 96 acre-feet. While the dam is classified as low hazard potential, it is regulated and inspected by the South Dakota Department of Environment and Natural Resources (DENR) to ensure its structural integrity and safety.
Managed by the Natural Resources Conservation Service, Sd Noname 193 plays a crucial role in water resource management within the area, with a maximum discharge capacity of 1200 cubic feet per second. Despite its age, the dam's condition assessment remains unrated, highlighting the need for regular monitoring and maintenance to uphold its functionality. The dam's primary purpose and associated structures are not specified, emphasizing the importance of ongoing assessments and risk management measures to mitigate any potential hazards.
Located within the St. Paul District of the US Army Corps of Engineers jurisdiction, Sd Noname 193 is a key infrastructure supporting water resource management in the region. With its state-regulated status and compliance with inspection and permitting requirements, this dam serves as a vital component in the local water supply system. As climate enthusiasts and water resource stakeholders, it is essential to stay informed about the condition and management of Sd Noname 193 to ensure sustainable water resource practices in the area.

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.
