Summary
Built in 1950 by the Natural Resources Conservation Service, this earth-type dam stands 22 feet tall and stretches 550 feet in length. With a storage capacity of 150 acre-feet and a maximum discharge of 3700 cubic feet per second, Sd Noname 182 serves primarily for flood control purposes.
Managed by the South Dakota Department of Environment and Natural Resources, Sd Noname 182 is regulated, permitted, inspected, and enforced to ensure its safety and compliance with state regulations. Despite being classified as low hazard potential with a condition assessment of "Not Rated," the dam's emergency action plan status, risk assessment, and risk management measures are currently undisclosed. The dam has not been modified in recent years, and its last inspection date, as well as inspection frequency, remain unspecified.
With its strategic location along the TR-WHITE RIVER, Sd Noname 182 plays a crucial role in managing water resources and mitigating potential flood risks in the region. As a significant earth-type dam in South Dakota, its infrastructure and operational status are closely monitored by state regulatory agencies to ensure public safety and environmental protection. While the dam's emergency preparedness and risk assessment details are yet to be fully disclosed, its historical significance and functional importance in water resource management underscore the need for ongoing monitoring and maintenance 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.
