Summary
The dam has a storage capacity of 56 acre-feet and serves the primary purpose of water resource management along the TR-BAD RIVER. Managed by the South Dakota Department of Environment and Natural Resources (DENR), the dam is regulated, permitted, inspected, and enforced to ensure its safety and functionality.
With a significant hazard potential and a condition assessment that is currently not rated, Sd Noname 8 is a crucial structure in the region that requires attention and monitoring. Despite being non-rated in condition assessment, the dam has a maximum discharge capacity of 525 cubic feet per second and plays a vital role in flood control and water supply management in the area. The dam is not operated by the US Army Corps of Engineers but is designed and maintained by the Natural Resources Conservation Service.
As a key infrastructure in South Dakota, Sd Noname 8 warrants continued evaluation and risk management measures to ensure its resilience in the face of changing climate conditions and potential hazards. The dam's association with the St. Paul District of the US Army Corps of Engineers and its significant storage capacity highlight its importance in water resource management for the region. Continuous monitoring and maintenance will be essential to uphold the safety and functionality of Sd Noname 8 for the community it serves.

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.
