Summary
Completed in 1959, this Earth-type dam stands at a height of 13 feet and has a length of 370 feet, providing a maximum storage capacity of 78 acre-feet. Situated on the TR-Bad River, this dam plays a crucial role in regulating water flow and mitigating potential flood risks in the area.
Managed by the Natural Resources Conservation Service, Sd Noname 46 is subject to state regulations, inspections, and enforcement, ensuring its structural integrity and safety for the surrounding community. With a low hazard potential and a current condition assessment of "Not Rated", this dam remains a vital resource for water management in the region. Despite lacking detailed information on emergency action plans and risk assessments, Sd Noname 46 still serves as a key infrastructure for water resource and climate enthusiasts to study and monitor.
As part of the St. Paul District of the US Army Corps of Engineers, Sd Noname 46 contributes to the overall water management system in South Dakota. With its strategic location in the city of Philip and under the jurisdiction of the South Dakota Department of Environment and Natural Resources, this dam stands as a testament to the ongoing efforts to ensure water security and sustainability in the region. For those interested in water resource management and climate resilience, Sd Noname 46 presents a valuable case study for understanding the role of dams in maintaining a balanced ecosystem and safeguarding against potential natural disasters.

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.
