Summary
Built in 1970 by the USDA NRCS, this earth dam stands at a height of 33 feet and has a storage capacity of 1428 acre-feet. With its primary purpose being flood risk reduction, the dam is regulated by the Mississippi Department of Environmental Quality and is considered to have a low hazard potential.
The dam features an uncontrolled spillway and outlet gates, and is designed with a buttress core and soil foundation. While the dam's condition assessment is currently not rated, it is inspected, permitted, and regulated by the state of Mississippi. Despite its moderate risk level, the Upper Yocona WS Str Y-14-15 Dam plays a vital role in protecting the surrounding area from potential flooding and demonstrates the ongoing efforts to manage water resources and climate impacts in the region.
As water resource and climate enthusiasts continue to monitor and assess the resilience of infrastructure like the Upper Yocona WS Str Y-14-15 Dam, it serves as a reminder of the importance of sustainable water management practices. With its strategic location and design features, this dam exemplifies the collaborative efforts between local government agencies and the USDA NRCS to mitigate flood risks and safeguard communities along the Yocona River 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.
