Summary
Built in 1935, this earth dam stands at a height of 21 feet and has a storage capacity of 70 acre-feet. It serves as an offstream structure for the TR-Bad River, with a maximum discharge capacity of 450 cubic feet per second.
Managed by the South Dakota Department of Environment and Natural Resources (DENR), Sd Noname 154 is regulated, inspected, and enforced by the state. Despite being rated as having a low hazard potential, the dam's condition is currently not rated, with no recent inspection data available. While the dam has not been modified in recent years, it is important for water resource and climate enthusiasts to keep an eye on its maintenance and safety measures.
With its proximity to the Bad River and contribution to local water management, Sd Noname 154 is a key infrastructure in the region. Although its condition assessment is pending, the dam's role in flood control and water storage underscores the importance of ongoing monitoring and upkeep to ensure the safety and sustainability of this vital resource.

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.
