Summary
Constructed in 1960 by the Natural Resources Conservation Service, this earth dam stands at 21 feet in height and spans 340 feet in length. With a storage capacity of 66 acre-feet and a maximum discharge of 1260 cubic feet per second, Sd Noname 47 serves as a crucial water resource infrastructure in the region.
Despite being regulated by the South Dakota Department of Environment and Natural Resources, Sd Noname 47 has a low hazard potential and is currently rated as "Not Rated" in terms of its condition assessment. While it has not been inspected recently, the dam is equipped with state permitting, inspection, and enforcement processes in place to ensure its safety and functionality. With its strategic location and purpose, Sd Noname 47 plays a vital role in water management and climate resilience efforts in the area.
As a key component of the St. Paul District's water infrastructure, Sd Noname 47 contributes to flood control, irrigation, and water supply needs in the region. Its stable condition, low hazard potential, and compliance with state regulations make it a reliable asset for water resource management. With ongoing monitoring and support from the relevant authorities, Sd Noname 47 continues to play a crucial role in safeguarding water resources and enhancing climate resilience 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.
