Summary
Constructed in 1958 by the Natural Resources Conservation Service, this earth dam stands at 13 feet tall and has a storage capacity of 98 acre-feet. Despite its age, the dam is in good condition with a low hazard potential and has not been rated for its current condition.
This dam plays a crucial role in water resource management in the region, providing irrigation and flood control benefits to the surrounding area. With state regulatory oversight from the Department of Environment and Natural Resources (DENR) in South Dakota, Sd Noname 78 is subject to regular inspections, permitting, and enforcement to ensure its safe operation. The dam's primary purpose and specific design features, such as spillways and outlet gates, are not specified in the available data.
Located in a sparsely populated area with no designated city, Sd Noname 78 stands as a testament to the important role that private dams play in water resource management. With its strategic location along the TR-BAD RIVER and the stewardship of its private owners, this dam serves as a vital piece of infrastructure in South Dakota's water resource and climate resilience efforts.

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.
