Summary
This earth dam, completed in 1936, has a storage capacity of 50 acre-feet and a maximum discharge of 1230 cubic feet per second. Despite not being rated for its condition, Sd Noname 178 is regulated, permitted, inspected, and enforced by the South Dakota Department of Environment and Natural Resources (DENR).
Situated on the TR-CHEYENNE River within the St. Paul District, Sd Noname 178 is overseen by the primary owner who is responsible for its operations. With a normal storage capacity of 25 acre-feet, this dam plays a crucial role in water resource management in the region. While lacking detailed information on its infrastructure and risk assessment, Sd Noname 178 stands as a testament to the enduring efforts in water conservation and climate resilience in South Dakota.
As a vital component of the local water infrastructure, Sd Noname 178 serves as a key resource for water enthusiasts and climate advocates. Its historical significance, regulatory framework, and operational capacity highlight the importance of sustainable water management practices in mitigating environmental risks and ensuring long-term water security. By understanding and appreciating the role of dams like Sd Noname 178, stakeholders can contribute to the preservation and enhancement of water resources in the face of climate challenges.

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.
