Summary
This dam serves the primary purpose of regulating water flow in the TRIB-BAD RIVER, with a storage capacity of 108 acre-feet. Managed by the Natural Resources Conservation Service, the dam is under state regulation and inspection, ensuring its safety and functionality for water resource management in the region.
With a low hazard potential and a current condition assessment of "Not Rated," Sd Noname 26 plays a crucial role in mitigating floods and providing reliable water supply for the area. Despite its age, the dam remains structurally sound and meets state permitting and enforcement standards. The dam's location in a rural setting underscores its importance for local water resource management and highlights the collaborative efforts of private ownership and government agencies in safeguarding water infrastructure in South Dakota.
As climate change impacts water availability and quality, dams like Sd Noname 26 play a vital role in sustainable water management practices. With a maximum discharge capacity of 3400 cubic feet per second, the dam serves as a critical infrastructure for flood control and water storage, showcasing the importance of proactive maintenance and monitoring to ensure its continued effectiveness in the face of evolving climate challenges.

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.
