Summary

Clark and completed in 2006. This earth dam serves primarily for recreation purposes and stands at a height of 22.75 feet, with a storage capacity of 285.33 acre-feet. The dam overlooks the UNT of UNT of Little Rocky Creek and is regulated by the Mississippi Department of Environmental Quality.

With a moderate risk assessment rating of 3, the condition of The Highlands Lake Dam is currently not rated, and its hazard potential remains undetermined. Despite its uncontrolled spillway and outlet gates, the dam has not been inspected or assessed for its emergency action plan preparedness. The surrounding area covers 13.55 acres with a drainage area of 0.19 square miles, making it a crucial resource for water management and climate enthusiasts interested in the conservation and safety of this vital infrastructure.

The Highlands Lake Dam stands as a significant structure in the Vicksburg District, attracting visitors for recreational activities while posing a moderate risk in terms of its safety and management. As a privately-owned entity in Mississippi, its maintenance, inspection, and regulatory oversight fall under the jurisdiction of the state's environmental quality department. This dam serves as a focal point for ongoing discussions and actions related to water resource management and climate adaptation efforts in the region, making it an essential asset to monitor and protect for the future.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
