Summary
Built in 1947 by the Natural Resources Conservation Service, this dam stands at a height of 15 feet and has a length of 750 feet. With a storage capacity of 168 acre-feet, it serves the primary purpose of water resource management in the region.
Despite being classified as having a low hazard potential, Sd Noname 126 is regulated and inspected by the South Dakota Department of Environment and Natural Resources. The dam has not been rated for its condition assessment and lacks emergency action plans and inundation maps. However, its historical importance in water management and its location in a vital watershed make it a significant structure for climate and water enthusiasts to monitor.
With a maximum discharge capacity of 525 cubic feet per second, Sd Noname 126 plays a crucial role in flood control and water supply for the surrounding area. While it may not have a designated emergency action plan in place, its low hazard potential and regulated status ensure that it continues to serve its purpose effectively in managing water resources in South Dakota.

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.
