Summary
The dam, primarily used for recreation, is an earth dam with a buttress core type and a height of 15 feet, providing a storage capacity of 57 acre-feet. The spillway is uncontrolled, and the dam poses a moderate risk level, according to the risk assessment.
Located in the Vicksburg District, this dam has not been rated for its condition and does not have an Emergency Action Plan (EAP) prepared. While the hazard potential is undetermined, the risk management measures and emergency contacts have not been updated. Despite these uncertainties, the dam serves as a vital water resource for the area, offering recreational opportunities and contributing to the local ecosystem.
As water resource and climate enthusiasts continue to monitor the impact of dams on the environment, Ms04420 Lake Dam stands out for its unique features and potential risks. With a focus on recreation and a moderate risk level, this privately owned dam in Mississippi serves as a reminder of the importance of proper maintenance and oversight to ensure the safety of both the structure and surrounding communities.

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.
