Summary
This earth dam, with a height of 20 feet, has a low hazard potential and is classified as not rated in terms of condition assessment. Despite its low hazard potential, the dam is regulated by the Mississippi Department of Environmental Quality and undergoes regular inspections to ensure public safety.
The dam features an uncontrolled spillway and serves the primary purpose of providing recreation opportunities for the local community. Although the dam has not been modified in recent years, it is considered to have a moderate risk level, with a risk assessment rating of 3. The dam is privately owned and falls under state jurisdiction, with the Mississippi Department of Environmental Quality overseeing its permitting, inspection, and enforcement processes. In case of emergencies, the dam management is advised to have an Emergency Action Plan in place to meet safety guidelines.
Overall, Lake Henry Dam is a significant water resource in Mississippi, offering recreational activities in a picturesque setting. While the dam has a moderate level of risk associated with it, the regular inspections and oversight by state regulatory agencies help in ensuring the safety and integrity of the structure. Water and climate enthusiasts can appreciate the importance of maintaining and managing dams like Lake Henry Dam to protect both the environment and public safety.

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.
