Summary
Built in 1960, this earth dam stands at a height of 27 feet and spans 750 feet in length, with a storage capacity of 285 acre-feet. Managed by the Natural Resources Conservation Service, Sd Noname 147 is regulated by the South Dakota Department of Environment and Natural Resources, ensuring compliance with state permitting, inspection, and enforcement requirements.
With a significant hazard potential, Sd Noname 147 has not been rated for its condition and does not have an emergency action plan in place. Despite these gaps in preparedness, the dam plays a crucial role in flood control and water storage activities in the region. It is important for water resource and climate enthusiasts to monitor the maintenance and safety measures of Sd Noname 147 to prevent potential risks and ensure the protection of downstream communities and ecosystems.
As part of the St. Paul District of the US Army Corps of Engineers, Sd Noname 147 serves as a key infrastructure for water management in South Dakota. While the dam has not been modified in recent years, ongoing risk assessments and management measures are essential to mitigate any potential threats and uphold the structural integrity of this vital resource. With Dusty Johnson (R) representing the area in Congress, there is a need for continued collaboration between federal, state, and local agencies to safeguard Sd Noname 147 and its surrounding environment for future generations.

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.
