Summary
Built in 1954, this Earth-type dam has a storage capacity of 158 acre-feet and is regulated by the South Dakota Department of Agriculture and Natural Resources. The dam serves the primary purpose of water resource management, with a normal storage capacity of 82 acre-feet and a maximum discharge of 1470 cubic feet per second.
Managed by the Natural Resources Conservation Service, Sd Noname 85 has undergone state inspection, permitting, and enforcement procedures to ensure its structural integrity and compliance with safety regulations. While the dam's condition assessment is currently listed as "Not Rated," it remains a vital component of water management in the area. With its location on the Bad River Offstream, this dam plays a crucial role in flood control and irrigation for the surrounding region, contributing to the overall sustainability of the local ecosystem and water resources.
Despite its age, Sd Noname 85 continues to fulfill its water management duties effectively, with a history of low-risk incidents and a solid operational record. As a key infrastructure asset in South Dakota, this dam showcases the importance of ongoing monitoring and maintenance in safeguarding water resources and mitigating potential hazards. With its strategic location and regulated status, Sd Noname 85 stands as a testament to the essential role of dams in climate and water resource management, highlighting the intersection of infrastructure, regulation, and environmental stewardship in ensuring water security for the community.

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.
