Summary
Located in Jackson County, it serves as a crucial structure on a tributary of the Bad River. With a height of 16 feet and a length of 450 feet, the dam has a storage capacity of 60 acre-feet, making it essential for water resource management in the area.
Although classified as low hazard potential, Sd Noname 166 is regulated by the South Dakota Department of Environment and Natural Resources, ensuring that it meets state inspection, enforcement, and permitting requirements. The dam has not been rated for its condition, but it continues to play a vital role in flood control and water supply in the region. The structure also falls under the jurisdiction of the St. Paul District of the US Army Corps of Engineers.
As a significant part of South Dakota's water infrastructure, Sd Noname 166 stands as a testament to the importance of sustainable water resource management and climate resilience. With its strategic location and functionality, this dam serves as a key player in safeguarding communities and ecosystems against flooding and ensuring a reliable water supply for various purposes.

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.
