Summary
Completed in 1966, this earth dam stands at a height of 13 feet and has a length of 590 feet, providing a storage capacity of 156 acre-feet. Managed by the South Dakota Department of Environment and Natural Resources (DENR), this dam is subject to state regulations, inspections, and enforcement to ensure its safety and compliance with standards.
Despite its low hazard potential and current "Not Rated" condition assessment, Sd Noname 127 plays a vital role in water resource management in the region. With a maximum discharge capacity of 1800 cubic feet per second, this dam helps regulate water flow and supports various downstream activities. While the dam has not been modified in recent years and lacks certain assessment information, its operation remains essential for maintaining water supply and environmental sustainability.
As a key structure in the St. Paul District of the US Army Corps of Engineers, Sd Noname 127 serves as a critical component of the local water infrastructure. While there are no associated structures or emergency action plans documented for this dam, its presence and regulation by state authorities highlight the importance of monitoring and maintaining water resources in South Dakota. Climate enthusiasts and water resource specialists alike can appreciate the significance of Sd Noname 127 in supporting the region's ecological balance and water management 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.
