Summary
Built in 1946, this earth dam stands at 22 feet tall and has a length of 342 feet, providing a storage capacity of 75 acre-feet. Managed by the South Dakota Department of Environment and Natural Resources, this dam is state-regulated and undergoes regular inspections, ensuring its structural integrity and safety.
Although not rated for its condition assessment, Sd Noname 3 has not undergone any modifications since its completion. With a maximum discharge of 150 cubic feet per second, this dam serves a primary purpose that is not specified in the data. Despite lacking information on its purposes, the dam's operation and maintenance are overseen by the Natural Resources Conservation Service, highlighting the collaborative effort in managing water resources in the region.
Situated within the St. Paul District, Sd Noname 3 has not been associated with any other structures and does not have an Emergency Action Plan prepared. While the dam may not pose a significant risk, continuous monitoring and adherence to regulatory guidelines are crucial to ensure the safety and sustainability of this water resource in South Dakota.

Dam Data Reference
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.
