Summary
Constructed in 1956 by the Natural Resources Conservation Service, this earth dam stands at a height of 22 feet and has a storage capacity of 141 acre-feet. With a low hazard potential and a condition assessment that is currently not rated, Sd Noname 212 plays a crucial role in regulating water flow and storage in the region.
Managed by DENR and subject to state regulation, Sd Noname 212 serves as a key infrastructure for water resource management in South Dakota. Despite its age, the dam continues to operate effectively with a maximum discharge capacity of 459 cubic feet per second. The surrounding area includes the city of MIDLAND and is under the jurisdiction of St. Paul District, ensuring proper maintenance and inspection of the structure.
For water resource and climate enthusiasts, Sd Noname 212 offers a fascinating example of how private ownership can contribute to the sustainability of water infrastructure. As the dam remains in compliance with state permitting and inspection requirements, it serves as a model for responsible water management. With its historical significance and ongoing function in the region, Sd Noname 212 stands as a testament to the importance of maintaining and regulating water resources for the benefit of local communities and the environment.

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.
