Summary
Built in 1953, this earth dam stands at a height of 20 feet and has a length of 499 feet, providing a storage capacity of 64 acre-feet. Despite being regulated by the state and having state jurisdiction, the dam is classified as low hazard potential with a condition assessment of 'Not Rated'.
Managed by the Natural Resources Conservation Service, Sd Noname 104 is equipped with state permitting, inspection, and enforcement processes in place. The dam has a maximum discharge capacity of 720 cubic feet per second and is designed to serve various purposes, although the primary purpose is not specified in the data. With its strategic location and importance in water resource management, Sd Noname 104 plays a crucial role in the local ecosystem and climate resilience efforts in South Dakota.
While the dam's emergency preparedness measures and risk assessment details are not provided, its overall low hazard potential and state-regulated status indicate a commitment to safety and effective management. As a significant structure in the St. Paul District, Sd Noname 104 contributes to the sustainability of water resources and environmental protection in the region, making it a vital asset for water resource and climate enthusiasts to monitor and support.

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.
