Summary
Owned by the local government and designed by NRCS, this earth dam with buttress core types stands at a height of 15 feet and has a storage capacity of 520 acre-feet. With a drainage area of 1.59 square miles and a low hazard potential, this dam plays a crucial role in managing water resources in the region.
Managed by the Mississippi Department of Environmental Quality, this dam is state-regulated and inspected, ensuring its structural integrity and compliance with safety standards. With a moderate risk assessment rating, emergency preparedness measures are in place, although the condition assessment is currently not rated. The dam's uncontrolled spillway type and lack of locks highlight its focus on flood risk reduction, serving as a vital infrastructure for protecting the surrounding area from potential water-related disasters.
As a part of the Vicksburg District, the Potococawa Watershed Structure Y-31a-05 Dam exemplifies the collaborative effort between local and state agencies in safeguarding water resources and mitigating flood risks. Its strategic location and design reflect a commitment to sustainable water management practices, showcasing the importance of effective dam structures in maintaining environmental resilience and safeguarding communities in the face of climate challenges.

Dam Data Reference
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.
