Summary
Constructed in 1937, this earth dam stands at a height of 28 feet and has a storage capacity of 140 acre-feet. Despite being regulated by the South Dakota Department of Environment and Natural Resources (DENR), the dam is currently rated as having a low hazard potential and its condition has not been formally assessed.
Owned by a private entity, Sd Noname 180 serves as a vital water resource in the region, providing a maximum discharge of 840 cubic feet per second. While the dam has not been modified in recent years and lacks a formal emergency action plan, it meets state permitting and inspection requirements. The presence of this dam underscores the importance of responsible water management in the face of changing climate patterns.
As climate enthusiasts and water resource advocates, it is crucial to monitor the condition of structures like Sd Noname 180 to ensure their continued safety and efficacy. With a focus on sustainability and risk management, efforts can be made to enhance the resilience of dams in the face of evolving environmental challenges. By staying informed and engaged in the regulation and oversight of critical water infrastructure, we can work towards a more secure and sustainable future for our water resources.

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.
