Summary
This dam, with a height of 20 feet and a length of 520 feet, serves the primary purpose of water resource management on the TRIB-BAD RIVER. Managed by the South Dakota Department of Environment and Natural Resources (DENR), this dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment.
With a maximum storage capacity of 144 acre-feet and normal storage of 72 acre-feet, Sd Noname 25 plays a crucial role in regulating water flow and providing flood protection in the region. The dam has state jurisdiction and is subject to regular inspections, permitting, and enforcement by the state regulatory agency. Despite not having an Emergency Action Plan (EAP) prepared or meeting certain guidelines, this dam remains a vital infrastructure for water resource management in South Dakota.
Supported by the Natural Resources Conservation Service, Sd Noname 25 is a testament to the collaborative efforts between private owners and government agencies in ensuring the safety and efficiency of water management structures. As climate change continues to impact water resources, dams like Sd Noname 25 will play a crucial role in mitigating risks and ensuring sustainable water management practices in the region.

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.
