Summary
Standing at a height of 21 feet with a length of 255 feet, this dam has a storage capacity of 428 acre-feet and a maximum discharge of 399 cfs. Despite being classified as having a significant hazard potential, the dam's condition assessment is currently listed as "Not Rated."
Operated by the Natural Resources Conservation Service, Sd Noname 208 is regulated and permitted by the South Dakota Department of Environment and Natural Resources. The dam is subject to state inspections, enforcement, and jurisdiction, ensuring its compliance with safety standards and regulations. While the dam has not been modified in recent years, it is considered to have a moderate risk level based on a risk assessment rating of 3.
With Dusty Johnson (R) as the representative of the area, Sd Noname 208 poses as a critical infrastructure for water resource management and flood control efforts in the region. As water resource and climate enthusiasts, it is essential to monitor and assess the condition of such dams to ensure the safety and sustainability of our water infrastructure in the face of changing climate patterns and increasing water demands.

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.
