Summary
Standing at a height of 24 feet, this earth dam with a buttress core has a storage capacity of 130 acre-feet, with a normal storage level of 85 acre-feet. The dam spans a surface area of 8 acres and serves as a popular spot for water resource and climate enthusiasts to enjoy outdoor activities such as fishing, boating, and picnicking.
Managed by the Mississippi Department of Environmental Quality, Lake Tallaha Dam features an uncontrolled spillway and is currently rated as having an undetermined hazard potential and a moderate risk level. Although the dam's condition has not been formally assessed, it meets state regulations for inspection, permitting, and enforcement. The dam does not have associated locks or outlet gates, and its emergency action plan status, inundation maps, and risk management measures are currently undefined. Overall, Lake Tallaha Dam offers a picturesque setting for recreational pursuits while maintaining a moderate level of risk management and safety measures.

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.
