Summary

Managed by the Natural Resources Conservation Service, this dam on the TR-BAD RIVER has a storage capacity of 73 acre-feet and a maximum discharge of 630 cubic feet per second. While the dam is classified as low hazard potential, its condition is currently not rated, indicating a need for further assessment.

Despite its age, Sd Noname 113 is regulated and inspected by the South Dakota Department of Environment and Natural Resources, ensuring its compliance with state regulations and safety standards. The dam's primary purpose and associated structures are not specified, but its location within the St. Paul District of the US Army Corps of Engineers suggests a level of federal oversight. With a normal storage capacity of 32 acre-feet, this dam plays a crucial role in water resource management and climate resilience in the region.

As a hub for water resource and climate enthusiasts, Sd Noname 113 presents an intriguing case study of dam infrastructure in South Dakota. With its historical significance, state jurisdiction, and regulatory compliance, this privately owned dam serves as a key component of the local watershed, providing essential water storage and flood control capabilities. As efforts to address climate change and enhance water security continue to gain momentum, the role of dams like Sd Noname 113 in sustainable water management practices cannot be overlooked.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
