Summary
Constructed in 1965 by the USDA NRCS, this earth dam with a buttress core stands at a height of 30 feet and spans a length of 833 feet. Its primary purpose is flood risk reduction, serving to protect the surrounding area from potential inundation during periods of high water flow.
With a storage capacity of 370 acre-feet and a normal storage level of 85 acre-feet, the dam plays a crucial role in managing water resources in the Upper Yocona Watershed. Despite being designated as a low hazard potential structure, the dam is state-regulated by the Mississippi Department of Environmental Quality, ensuring that it meets all necessary safety and environmental standards. The risk assessment for the dam indicates a moderate level of risk, prompting the need for ongoing monitoring and management to ensure its continued effectiveness in flood control and water resource protection.
Overall, the Upper Yocona Watershed Structure Y-14-05 Dam serves as a vital infrastructure for the local community, providing essential flood risk reduction measures and contributing to the sustainable management of water resources in the area. As a key component of the watershed, this earth dam underscores the importance of proactive maintenance and monitoring to ensure its continued safety and efficacy in safeguarding against potential flooding events. For water resource and climate enthusiasts, this dam represents a fascinating example of how infrastructure can be utilized to mitigate the impacts of extreme weather events and protect communities from the risks associated with 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.
