Summary
The dam, primarily built for recreational purposes, is an earth dam with a buttress core type and stands at a height of 12 feet, providing a storage capacity of 150 acre-feet. The spillway type is uncontrolled, and the hazard potential of the dam is currently undetermined, with a moderate risk assessment rating of 3.
Although the dam's condition is not rated, it is inspected, permitted, and regulated by the state authorities, ensuring its safety and compliance with environmental standards. Located within the Vicksburg District, the dam sits at a latitude of 32.54222975 and longitude of -89.14430991. Despite lacking detailed information on its construction and modification history, the dam serves as a significant recreational resource in the area, offering opportunities for water-based activities and enjoyment for visitors.
As a vital component of the local water resource infrastructure, Henry Lake Dam plays a crucial role in providing recreational opportunities and contributing to the overall water management efforts in the region. With its moderate risk assessment and undetermined hazard potential, ongoing monitoring and maintenance are essential to ensure the safety and functionality of the dam for both recreational users and the surrounding environment.

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.
