Summary
This earth dam, with a height of 30 feet, serves primarily for flood risk reduction along the TR-Yocona River and Kettle Creek. The dam has a NID storage capacity of 219 acre-feet and is classified as having a low hazard potential.
Managed by the Mississippi Department of Environmental Quality, the dam is state-regulated, permitted, inspected, and enforced to ensure its safety and functionality. The dam features an uncontrolled spillway and outlet gates, with no associated locks, and has not been rated for condition assessment. Despite its moderate risk assessment level, the dam currently does not have an emergency action plan in place, indicating room for improvement in emergency preparedness and risk management measures.
Overall, the Upper Yocona Watershed Structure Y-14-02 Dam plays a crucial role in mitigating flood risks in the area, showcasing the importance of proper dam maintenance and emergency planning for water resource and climate enthusiasts to ensure the safety and resilience of such vital infrastructure in the face of changing environmental conditions.

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.
