Summary
Built in 1950, this Earth-type dam stands at a height of 18 feet and spans 450 feet in length, with a storage capacity of 98 acre-feet. Despite its age, the dam is considered to have a low hazard potential and its condition remains unrated.
Owned and regulated by the South Dakota Department of Environment and Natural Resources (DENR), Sd Noname 125 is subject to state permitting, inspection, and enforcement. The dam is equipped with outlet gates and can handle a maximum discharge of 6500 cubic feet per second. Although there are no associated structures or emergency action plans in place, the dam meets state jurisdiction and regulatory requirements.
Located in a remote area with no specific city designation, Sd Noname 125 is overseen by the St. Paul District of the US Army Corps of Engineers. With Dusty Johnson (R) as the Congressional Representative for the district, the dam plays a crucial role in managing water resources and mitigating flood risks in the region. Despite its unassuming name, Sd Noname 125 stands as a testament to the vital role of private dams in water resource management 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.
