Summary
Completed in 2007, this dam stands at a height of 42 feet with a hydraulic height of 36 feet and a structural height of 51 feet. It has a length of 3000 feet and a storage capacity of 2570.2 acre-feet, making it a significant water resource in the area.
Managed by the Mississippi Department of Environmental Quality, the dam is regulated, permitted, inspected, and enforced by the state to ensure its safe operation. With a low hazard potential and a satisfactory condition assessment, Lake Heritage Dam poses a moderate risk level, warranting risk management measures. The dam's emergency action plan was last revised in 2007, and the last inspection took place in March 2016, highlighting the importance of ongoing monitoring and maintenance to safeguard the surrounding community and environment.
Overall, Lake Heritage Dam serves as a vital infrastructure for recreational activities while also contributing to water resource management in the region. Its design, construction, and regulatory oversight reflect a commitment to both public safety and environmental sustainability, making it an essential component of water resource and climate enthusiasts' interest in understanding and preserving our natural resources.

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.
