Summary
The dam, classified as an Earth type with Buttress core, stands at a height of 38 feet and has a hydraulic height of 30 feet. It has a storage capacity of 540 acre-feet, with a normal storage level of 315 acre-feet, covering a surface area of 45 acres within the park.
The dam's spillway is of the uncontrolled type, and its hazard potential is rated as low with a satisfactory condition assessment as of November 2015. The risk assessment for the dam is moderate (3), indicating a moderate level of risk associated with its operation. While the dam is not owned or funded by federal agencies, the Mississippi Department of Environmental Quality regulates it, including permitting, inspection, and enforcement activities to ensure its safe operation and maintenance. Overall, Tishomingo State Park Lake Dam serves as a vital component of the recreational infrastructure in the area, providing opportunities for outdoor activities and water-based recreation for enthusiasts and visitors to enjoy.

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.
