Summary
Built in 1956 by the Natural Resources Conservation Service, this earthen dam stands at a height of 18 feet and has a length of 350 feet, providing a storage capacity of 65 acre-feet. The dam is regulated by the South Dakota Department of Environment and Natural Resources, with state permitting, inspection, and enforcement procedures in place to ensure its safe operation.
Despite its low hazard potential and current "Not Rated" condition assessment, Sd Noname 194 plays a crucial role in water resource management within the region. With a maximum discharge capacity of 1500 cubic feet per second, the dam serves as a vital structure for flood control and water storage along the Cheyenne River. While the dam has not been modified in recent years and lacks detailed risk assessment measures, its importance in mitigating potential water-related disasters cannot be understated.
As water resource and climate enthusiasts continue to monitor the state of dams like Sd Noname 194, it is essential to recognize the critical role these structures play in safeguarding communities and ecosystems from the impacts of extreme weather events. By staying informed about the regulatory oversight, maintenance, and emergency preparedness efforts surrounding dams like Sd Noname 194, stakeholders can work towards ensuring the long-term resilience and sustainability of water infrastructure in South Dakota and beyond.

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.
