Summary
Built in 1974 by the USDA NRCS, this earth dam stands at a height of 26 feet and has a storage capacity of 4550 acre-feet. It serves the primary purpose of flood risk reduction and is regulated by the Mississippi Department of Environmental Quality.
The dam, situated on the Yocona River and Toccopola Creek, has a low hazard potential and is classified as having a moderate risk level. Despite not being rated for its condition assessment, the dam is regularly inspected, permitted, and enforced by state agencies. The spillway is uncontrolled, with outlet gates of the same nature. While the dam has not been modified in recent years and lacks emergency action plans, it remains an important structure in the region's water resource management and climate resilience efforts.
Enthusiasts of water resources and climate will find the Upper Yocona Watershed Structure Y-14-09 Dam to be a fascinating example of local government infrastructure designed for flood risk reduction. With its reliance on natural resources conservation practices and its critical role in managing water flow in the area, this dam showcases the importance of sustainable water management strategies in the face of changing climate conditions. As a regulated and inspected structure, it highlights the ongoing efforts to ensure the safety and effectiveness of such essential water management infrastructure in Mississippi.

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.
