Summary
This dam, situated on the TR-BAD RIVER, serves various purposes such as water storage and flood control in the region. Despite its low hazard potential, the dam is regulated, permitted, inspected, and enforced by the South Dakota Department of Environment and Natural Resources (DENR) to ensure its safety and compliance with state regulations.
Managed by private owners, Sd Noname 249 has a normal storage capacity of 28 acre-feet and a maximum discharge of 1300 cubic feet per second. Although the dam's condition is currently not rated, it meets state jurisdiction requirements and undergoes regular inspections for any necessary maintenance or improvements. Additionally, the surrounding area's emergency action plan (EAP) status and risk assessment for the dam are currently not documented, indicating a potential area for further evaluation and preparedness in case of emergencies.
With its strategic location and vital role in water resource management, Sd Noname 249 is a significant infrastructure contributing to the overall water conservation efforts in South Dakota. As climate change continues to impact water resources and weather patterns, the importance of well-maintained dams like Sd Noname 249 becomes increasingly crucial for ensuring water security and flood protection in the region.

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.
