Summary
This earth dam stands at a height of 13 feet and has a storage capacity of 129 acre-feet, with a maximum storage of 129 acre-feet. The dam features an uncontrolled spillway and is classified as having a low hazard potential.
Managed by the Mississippi Department of Environmental Quality, this dam is subject to state regulations, inspections, and enforcement measures to ensure its safety and compliance. Despite being rated as "Not Rated" in terms of condition assessment, the overall risk assessment for this dam is moderate (3), indicating a need for ongoing monitoring and risk management measures. The dam does not have an emergency action plan in place, raising some concerns about preparedness in case of a sudden event.
Enthusiasts interested in water resources and climate will find Ms04421 Lake Dam a fascinating structure to study, given its recreational purpose, low hazard potential, and moderate risk assessment. The dam's location in Yazoo, Mississippi, and its ownership by a private entity add unique dimensions to its operational and regulatory oversight. As climate change impacts water resources, understanding the management and condition of structures like this dam becomes increasingly important for ensuring public safety and environmental resilience.

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.
