Summary
Constructed in 1966 by the Natural Resources Conservation Service, this earth dam stands at a height of 27 feet and has a length of 236 feet. With a maximum storage capacity of 22 acre-feet and a normal storage of 5 acre-feet, Sd Noname 28 plays a crucial role in water resource management in the area.
Despite its importance, Sd Noname 28 is classified as having a low hazard potential and has not been rated for its condition. However, the dam is regulated by the South Dakota Department of Environment and Natural Resources, which ensures that it undergoes regular inspections and maintenance. With a maximum discharge capacity of 546 cubic feet per second, the dam is equipped to handle potential flooding events and protect downstream communities.
While Sd Noname 28 has not been assessed for its emergency preparedness measures or risk management strategies, its presence serves as a vital infrastructure component for water supply and flood control in the region. As climate change continues to impact water resources, the proper maintenance and regulation of dams like Sd Noname 28 will be essential to mitigating risks and ensuring the safety of surrounding communities.

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.
