Summary
This private dam on TR-Big Creek, with a modest height of 12 feet, is primarily used for recreation purposes and has a low hazard potential. Despite being uncontrolled, the dam has a solid earth core buttress structure and is regulated by the Mississippi Department of Environmental Quality.
The dam boasts a storage capacity of 90 acre-feet, offering a serene oasis for water resource and climate enthusiasts to enjoy the beauty of the surrounding area. With its uncontrolled spillway and outlet gates, Mcminn Lake Dam presents a moderate risk level of 3, indicating a need for ongoing risk management measures to ensure its safety and integrity. While the dam's condition assessment is currently not rated, its significance in providing recreational opportunities underscores the importance of maintaining its structural integrity for future use.
As a vital part of the local ecosystem, Mcminn Lake Dam serves as a valuable resource for the community, attracting visitors with its tranquil waters and picturesque surroundings. Its location in the Vicksburg District adds to its appeal, offering a peaceful retreat for those seeking to connect with nature.

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.
