Summary
Built in 1969 by the Natural Resources Conservation Service, this dam stands at 23 feet high and spans 300 feet in length, providing a storage capacity of 106 acre-feet. With a maximum discharge of 1000 cubic feet per second, Sd Noname 259 serves as a crucial water resource infrastructure in the region.
Managed by the South Dakota Department of Environment and Natural Resources, Sd Noname 259 is regulated, permitted, inspected, and enforced to ensure its structural integrity and safety. Despite being classified as low hazard potential, the dam's condition is currently marked as "Not Rated," indicating a need for further assessment. The dam does not have an Emergency Action Plan in place, and there is no information available regarding risk assessment or management measures.
As an essential component of water resource management in the region, Sd Noname 259 presents both opportunities and challenges for climate and water enthusiasts. With its historical significance and ongoing regulatory oversight, the dam serves as a focal point for discussions on dam safety, emergency preparedness, and risk mitigation strategies in the face of changing climate patterns and increasing water resource 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.
