Summary
Built in 1955, this Earth-type dam serves the purpose of off-stream water storage, with a maximum capacity of 110 acre-feet and a normal storage level of 54 acre-feet. The dam has a length of 370 feet and is regulated by the South Dakota Department of Agriculture and Natural Resources. Despite being inspected in 1973, its current condition remains unrated.
Managed by the Natural Resources Conservation Service, Sd Noname 81 plays a crucial role in water resource management in the region. It has a maximum discharge capacity of 1700 cubic feet per second and ensures water availability for agricultural and environmental purposes. Although its emergency action plan status and risk assessment are not specified, the dam continues to provide valuable benefits to the community while adhering to state regulatory standards for inspection and enforcement.
As an essential component of the local water infrastructure, Sd Noname 81 contributes to the overall water management efforts in South Dakota. With its strategic location and operational efficiency, the dam helps mitigate water scarcity issues and supports sustainable development in the region. Climate and water resource enthusiasts can appreciate the significance of this structure in maintaining a reliable water supply for various stakeholders, while also emphasizing the importance of ongoing monitoring and maintenance to ensure its continued effectiveness in the face of changing environmental 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.
