Summary
This earth dam, with a height of 12 feet and a storage capacity of 69 acre-feet, serves as a low hazard potential barrier. The dam, constructed with buttress core types, has a surface area of 9 acres and a spillway type classified as uncontrolled.
Managed by the Mississippi Department of Environmental Quality, this dam undergoes state regulation, inspection, and enforcement to ensure its safety and compliance with environmental guidelines. Despite being rated as not assessed in terms of condition, the dam poses a moderate risk, signaling the need for risk management measures to mitigate potential hazards. Although the dam has not been modified in recent years, its maintenance and emergency action plans remain crucial for addressing any unforeseen events.
With Congressman Bennie G. Thompson overseeing the Mississippi region, the importance of maintaining the integrity of dams like Ms04459 Lake Dam becomes evident in safeguarding water resources and adapting to climate challenges. This structure serves as a vital recreational asset while highlighting the need for proactive risk assessment and management in the face of changing environmental conditions.

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.
