Ms04540 Lake Dam Reservoir Report
Last Updated: March 2, 2026
Ms04540 Lake Dam in Yazoo, Mississippi, stands as a vital water resource managed by the MS Department of Environmental Quality.
Summary
This private dam, primarily intended for recreational use, features an earth core type with buttress foundations, reaching a height of 18 feet and holding a storage capacity of 67 acre-feet. The dam's spillway is uncontrolled, with a low hazard potential and a moderate risk assessment rating of 3.
Despite its low hazard potential, the dam's condition remains unrated, yet it undergoes regular state permitting, inspection, and enforcement. Located within the Vicksburg District and owned by a private entity, Ms04540 Lake Dam provides critical water storage and recreational opportunities for the local community. With a surface area of 6 acres and a normal storage capacity of 56 acre-feet, the dam plays a crucial role in water resource management in the region.
As climate change continues to impact water resources, the maintenance and regulation of dams like Ms04540 Lake Dam become increasingly important. With its moderate risk assessment and state-regulated status, this dam serves as a significant asset in both water storage and recreational activities, highlighting the need for ongoing monitoring and management to ensure its continued safety and functionality in the face of changing environmental conditions.

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.
