Summary
Completed in 1971, this dam has a height of 26 feet and a storage capacity of 1086 acre-feet, offering protection to the surrounding area from potential flooding events. Despite being classified as having a low hazard potential, the dam is regulated by the Mississippi Department of Environmental Quality and undergoes regular inspections to ensure its structural integrity.
Situated in the picturesque city of Yocona, Mississippi, this dam plays a critical role in managing water resources in the region and contributes to the overall watershed management efforts. With a drainage area of 2.74 square miles, the dam helps control the flow of water and mitigate flood risks for the local community. Although the dam's condition is currently not rated, its risk assessment is moderate, highlighting the importance of ongoing monitoring and maintenance to ensure its continued effectiveness in flood protection.
Managed by the Natural Resources Conservation Service, the Upper Yocona Watershed Structure Y-14-06 Dam serves as a vital infrastructure for water resource management in the area. As part of the flood risk reduction system along the Yocona River, this earth dam provides valuable protection against potential inundation events, contributing to the resilience of the local ecosystem and community. Despite its low hazard potential, the dam's moderate risk assessment underscores the need for continued vigilance and proactive measures to maintain its functionality and safeguard the surrounding areas from flooding risks.

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.
