Summary
The dam, constructed for the primary purpose of water resource management along the TR Bad River, has a storage capacity of 310 acre-feet and a maximum discharge rate of 550 cubic feet per second. Despite being of Earth dam type and having uncontrolled spillways, the dam is regulated and inspected by the South Dakota Department of Environment and Natural Resources (DENR) to ensure its safety and compliance with state regulations.
With a significant hazard potential and a moderate risk assessment rating, Sd Noname 205 is closely monitored for any potential safety concerns. Although its condition assessment is currently listed as "Not Rated," the dam's risk management measures and emergency action plan readiness remain undisclosed. As one of the many structures under the jurisdiction of the St. Paul District of the US Army Corps of Engineers, Sd Noname 205 plays a vital role in water resource management in the Haakon County area, serving as a critical infrastructure for flood control and water supply purposes.
As water resource and climate enthusiasts, it is essential to recognize the importance of dams like Sd Noname 205 in ensuring water security and mitigating risks associated with extreme weather events. By understanding the regulatory oversight, storage capacity, and risk assessment of such structures, we can better appreciate their role in safeguarding communities and ecosystems against potential water-related hazards. The data on Sd Noname 205 serves as a reminder of the ongoing efforts to manage and maintain our water infrastructure for a sustainable and resilient future.

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.
