Summary
The dam, primarily built for recreational purposes, is an earth dam with a buttress core type standing at a height of 20 feet, providing a storage capacity of 180 acre-feet. Despite being classified as low hazard potential with a moderate risk assessment, the dam's condition is currently not rated, suggesting a need for further evaluation and maintenance to ensure its long-term safety and functionality.
Located in Rankin County, Mississippi, Corley Lake Dam is under the jurisdiction of the Vicksburg District, with Congressman Michael Guest representing the area. The dam features an uncontrolled spillway type and has not been modified or fully inspected in recent years. While it serves a vital role in recreation and water storage, the lack of updated risk assessment and emergency preparedness measures could pose challenges in managing potential hazards and ensuring the dam's resilience to changing climate conditions. As water resource and climate enthusiasts, it is crucial to monitor and advocate for the proper maintenance and regulation of structures like Corley Lake Dam to safeguard our communities and natural environments.

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.
