Summary
Constructed in 1956 by the Natural Resources Conservation Service, this earth dam stands at a height of 20 feet and has a storage capacity of 96 acre-feet. The dam, situated on the TRIB-BAD RIVER, serves multiple purposes and has a low hazard potential.
Despite its age, Sd Noname 38 has not been rated for its condition and lacks an Emergency Action Plan (EAP) or updated risk assessment. The dam has a maximum discharge rate of 625 cubic feet per second and a normal storage capacity of 44 acre-feet. While it has not undergone recent inspections, the dam remains under the jurisdiction of the state and is subject to state permitting and enforcement.
For water resource and climate enthusiasts, Sd Noname 38 presents an intriguing case study of a privately owned dam in South Dakota with limited regulatory oversight and potential safety concerns. With its historic construction and modest storage capacity, this dam serves as a reminder of the importance of regular inspections, emergency preparedness, and risk management in safeguarding our water resources and infrastructure against potential hazards.

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.
