Summary
Built in 1955, this earth dam stands at a height of 30 feet and has a storage capacity of 84 acre-feet, with a normal storage level of 52 acre-feet. The dam plays a crucial role in water resource management in the region, with a maximum discharge capacity of 735 cubic feet per second.
Managed and regulated by the South Dakota Department of Environment and Natural Resources (DENR), Sd Noname 210 is classified as having a significant hazard potential. Despite not being rated for its condition assessment, the dam is subject to regular state inspections, enforcement, and permitting to ensure its structural integrity and safety. The dam's emergency action plan status, risk assessment, and management measures are currently not specified, highlighting the need for ongoing monitoring and evaluation.
While the dam has not been modified in recent years and lacks detailed information on certain aspects like spillway type and outlet gates, its critical role in water storage and flood control cannot be understated. With its location in a rural area and its association with the St. Paul District of the US Army Corps of Engineers, Sd Noname 210 serves as a vital infrastructure piece for the local community and underscores the importance of effective dam management in the face of changing climate conditions.

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.
