Summary
Built in 1974 by the USDA NRCS, this earth dam stands at a height of 27 feet and has a storage capacity of 1271 acre-feet. The dam plays a crucial role in managing the flow of the Yocona River and Toccopola Creek, ultimately reducing the risk of flooding in the surrounding areas.
Managed by the local government and regulated by the Mississippi Department of Environmental Quality, the Y-14-10 Dam is classified as having a low hazard potential with a moderate risk assessment rating. Although not currently rated for condition assessment, the dam serves its primary purpose effectively and is inspected, permitted, and enforced by state agencies to ensure its continued safety and functionality. With its uncontrolled spillway and outlet gates, the dam plays a vital role in safeguarding the community against potential flood events.
As water resource and climate enthusiasts, understanding the infrastructure and management of dams like the Upper Yocona Watershed Structure Y-14-10 Dam is crucial for sustainable water management practices. With a clear focus on flood risk reduction and state-regulated operations, this dam serves as a reliable asset in protecting the local environment and community from the impacts of extreme weather events and changing climate patterns.

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.
