Summary
Built in 1958 by the Natural Resources Conservation Service, this dam stands at a height of 13 feet with a length of 520 feet, providing a maximum storage capacity of 102 acre-feet. While it has a low hazard potential, the dam is not currently rated for its condition assessment.
Despite being state regulated and permitted, Sd Noname 39 has not been inspected recently, and emergency action and risk assessment protocols are not up to date. The dam is under the jurisdiction of the South Dakota Department of Environment and Natural Resources, ensuring compliance with state regulations. With its location in a rural area and minimal associated structures, the primary purpose of Sd Noname 39 remains unspecified.
Water resource and climate enthusiasts may find interest in the historical significance of Sd Noname 39 as a part of South Dakota's water infrastructure network. Its presence along the TR-Bad River highlights the importance of dams for water management in the region, while also emphasizing the need for regular inspection and upkeep to ensure public safety and environmental protection. Further research and monitoring of Sd Noname 39 could provide valuable insights into the resilience of such structures in the face of changing climate conditions.

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.
