Summary
The dam, completed in 1980, serves a primary purpose of recreation, with a storage capacity of 386 acre-feet and a surface area of 25.6 acres. Owned privately, the dam is regulated and inspected by the Mississippi Department of Environmental Quality to ensure its safety and compliance with state regulations.
With a hydraulic height of 30 feet and a spillway width of 12 feet, Heritage Lake Dam poses a high hazard potential but is currently assessed as being in fair condition. Inspected every five years, the dam's last assessment in December 2020 deemed it to have moderate risk management measures in place. While it lacks certain features like outlet gates and locks, the dam continues to provide vital water storage and recreational opportunities for the surrounding area.
Located in Jasper County, Mississippi, Heritage Lake Dam is a significant part of the local landscape, offering not only a picturesque recreational spot but also serving as a crucial water management structure. As water resources and climate continue to be of utmost importance, the upkeep and regulation of dams like Heritage Lake Dam remain essential to ensure the safety and sustainability of the surrounding environment and community.

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.
