Summary
#14 is a privately owned dam located in Jones, South Dakota, along a tributary of the Bad River. Completed in 1979, this earth-type dam stands at a height of 26 feet and has a storage capacity of 23 acre-feet. The dam plays a crucial role in water resource management in the region, with a low hazard potential and currently not rated in terms of its condition assessment.
Operated under the regulatory oversight of the South Dakota Department of Environment and Natural Resources (DENR), Olson Ranches INC. #14 is subject to state permitting, inspection, and enforcement protocols. Despite its age, the dam has not undergone recent modifications or condition assessments, indicating a need for updated evaluations to ensure its continued safety and efficacy in water storage and flood control. In the event of an emergency, the dam's emergency action plan (EAP) status and risk management measures remain undisclosed, necessitating further attention to preparedness and response protocols.
Overall, Olson Ranches INC. #14 serves as a vital infrastructure for water management in the area, contributing to irrigation, flood control, and environmental conservation efforts. With proper monitoring and maintenance, this dam can continue to fulfill its essential role in safeguarding water resources and mitigating climate-related challenges in South Dakota.

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.
