Summary
Built in 1950, this earth dam stands at 410 feet in length and has a storage capacity of 63 acre-feet. Situated on the TR-Bad River, it is regulated by the South Dakota Department of Environment and Natural Resources (DENR) and undergoes regular inspections, enforcement, and permitting processes to ensure its safety and compliance with state regulations.
Located in the city of Philip, Sd Noname 74 serves as a vital structure for water resource management in the area, with a maximum discharge capacity of 625 cubic feet per second. While the dam's condition assessment is currently rated as "Not Rated," its emergency action plan (EAP) status, risk assessment, and management measures are yet to be documented. The dam's primary purpose and associated structures are unspecified, but its role in controlling water flow on the Bad River demonstrates its importance in mitigating potential flooding and safeguarding downstream communities.
Owned and operated by a private entity, Sd Noname 74 plays a crucial role in the overall water infrastructure of St. Paul District in South Dakota. With its strategic location, regulated status, and low hazard potential, this dam stands as a testament to the collaborative efforts between private owners and state agencies in ensuring the safety and sustainability of water resources 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.
