Summary
Constructed in 1960, this dam stands at a height of 13 feet and has a length of 370 feet, with a storage capacity of 156 acre-feet. The dam is regulated by the South Dakota Department of Environment and Natural Resources and is inspected, permitted, and enforced by state authorities to ensure its safety and compliance with regulations.
Located on the TR-Bad River, Sd Noname 31 serves as a crucial water resource for the surrounding area, with a maximum discharge of 1050 cubic feet per second. Despite being classified as having a low hazard potential, the dam's condition is currently not rated, highlighting the need for ongoing monitoring and maintenance. Managed by the Natural Resources Conservation Service, this dam plays a vital role in water management and conservation efforts in the region.
While specific details such as the dam's structural integrity and emergency preparedness are not currently assessed, the presence of Sd Noname 31 underscores the importance of sustainable water resource management in the face of climate change and increasing water scarcity. As water resource and climate enthusiasts, it is crucial to stay informed and engaged in the maintenance and regulation of vital infrastructure like Sd Noname 31 to ensure the resilience of our water systems in the face of evolving environmental challenges.

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.
