Summary
Built in 1950, this dam stands at a height of 14 feet and has a length of 560 feet, with a storage capacity of 94 acre-feet. The dam is situated on the TR-BAD RIVER and is regulated by the South Dakota Department of Environment and Natural Resources (DENR).
Despite its age, Sd Noname 155 has a low hazard potential and is currently rated as "Not Rated" in terms of its condition assessment. The dam has not undergone recent inspections, but it is subject to state permitting, inspection, and enforcement. In the event of an emergency, the dam does not have an Emergency Action Plan (EAP) prepared, raising concerns about its readiness in times of crisis. The dam is not owned or funded by any federal agencies, indicating a reliance on private ownership for its maintenance and operation.
Overall, Sd Noname 155 serves as a crucial infrastructure for water resource management in the region, providing storage for up to 94 acre-feet of water. As climate change continues to impact water availability and precipitation patterns, the maintenance and monitoring of dams like Sd Noname 155 become increasingly important to ensure the safety of surrounding communities and ecosystems. Collaborative efforts between private owners, state regulators, and other stakeholders will be essential in safeguarding the functionality and integrity of this vital water resource structure.

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.
