Summary
Built in 1954, this earth dam stands at a height of 20 feet and spans 620 feet in length, with a storage capacity of 160 acre-feet. Situated on the TR-Bad River, this structure serves a vital role in managing water resources and mitigating flood risks in the region.
Despite being labeled as low hazard potential, the condition of Sd Noname 58 is currently not rated, highlighting the need for regular inspections and assessments to ensure its safety and functionality. While the dam's emergency action plan status and risk management measures are unknown, its location in a relatively remote area underscores the importance of proactive maintenance and monitoring to protect surrounding communities and the environment from potential hazards.
With its unique design and historical significance, Sd Noname 58 represents a key piece of infrastructure in South Dakota's water management system. As climate change continues to impact water resources and extreme weather events become more frequent, the importance of maintaining and updating structures like Sd Noname 58 to ensure their resilience and reliability is more crucial than ever for the sustainability of the region's water supply and flood protection efforts.

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.
