Summary

The dam, of Earth core type with buttress foundations, stands at a height of 15 feet and has a storage capacity of 53 acre-feet. Despite its low hazard potential, a moderate risk assessment rating highlights the importance of ongoing maintenance and monitoring.

Managed by the Mississippi Department of Environmental Quality, the dam is regulated, permitted, inspected, and enforced by state authorities to ensure its safety and compliance with regulations. While the dam's condition is currently not rated, the presence of an Emergency Action Plan (EAP) and risk management measures indicate a proactive approach to emergency preparedness and mitigation.

With its uncontrolled spillway and overall focus on recreation, Hank Harris Lake Dam serves as both a water resource and a climate enthusiast's haven. Its location within the Vicksburg District and the involvement of state agencies in its oversight demonstrate a commitment to the safety and enjoyment of this important water infrastructure.

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.
