Summary
Constructed in 1950, this earth dam stands at 26 feet high and spans 600 feet in length, with a storage capacity of 220 acre-feet. Managed by the South Dakota Department of Environment and Natural Resources (DENR), the dam is regulated, inspected, and enforced by the state, ensuring its safety and compliance with standards.
Although the dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment, it plays a crucial role in flood control and water management along the TR-BAD RIVER. With a maximum discharge capacity of 450 cubic feet per second, Sd Noname 164 helps to mitigate the risk of flooding and protect downstream areas. Despite not having a formal Emergency Action Plan (EAP) in place, the dam is monitored and maintained to meet safety guidelines.
Managed by the St. Paul District of the US Army Corps of Engineers, Sd Noname 164 serves as a vital infrastructure for water resource management in the region. With its strategic location and low hazard potential, this dam contributes to the overall resilience of the water system and demonstrates the importance of effective regulation and inspection in ensuring the safety and functionality of critical water infrastructure.

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.
