Summary
The dam's primary purpose is for recreation, specifically on Turkey Creek, with a maximum storage capacity of 135 acre-feet. The dam stands at a height of 20 feet and is classified as an earth dam with a buttress core type.
Managed by the Mississippi Department of Environmental Quality, Mabry Lake Dam is regulated, inspected, and enforced by state authorities to ensure its safety and compliance with environmental standards. Despite its low hazard potential and moderate risk assessment, the dam's condition assessment remains unrated. With uncontrolled spillways and outlets, the dam poses minimal risk but still requires ongoing monitoring and maintenance to mitigate any potential issues.
As a key feature in the Memphis District under the ownership of a private entity, Mabry Lake Dam serves as a crucial recreational resource for the local community while also requiring vigilant oversight to safeguard against any unforeseen emergencies or risks. Its strategic location and design make it a valuable asset for both water resource and climate enthusiasts interested in sustainable dam management practices.

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.
