Summary
Built in 1967 by the USDA NRCS, this dam serves primarily for flood risk reduction along the TR-Beatty Bayou. With a height of 17 feet and a storage capacity of 152 acre-feet, this structure plays a crucial role in managing water resources in the area.
The dam's low hazard potential and moderate risk assessment make it a vital component of the region's water infrastructure. Despite not being currently rated for condition assessment, the dam is regulated, inspected, and enforced by the Mississippi Department of Environmental Quality. With uncontrolled spillways and outlets, the structure is designed to handle potential overflow and emergencies, ensuring the safety and security of the surrounding communities in Whaley. As a key element in water resource management, the Potacocawa Watershed Structure Y-31a-18 Dam exemplifies the importance of sustainable infrastructure for climate resilience.
Overall, the Potacocawa Watershed Structure Y-31a-18 Dam stands as a testament to collaborative efforts between local government agencies and federal entities like the USDA NRCS. Its role in flood risk reduction, along with its strategic location in the Vicksburg District, highlights the importance of proactive water management in the face of changing climate patterns. As water resource and climate enthusiasts, understanding and supporting such critical infrastructure projects is essential for building a more sustainable and resilient future for our communities.

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.
