Summary
This earth dam stands at a height of 12 feet with a hydraulic height of 8 feet and a length of 1900 feet. The dam has a normal storage capacity of 128 acre-feet and a maximum storage capacity of 208 acre-feet, covering a surface area of 43 acres.
The dam controls the flow of Mill Bayou-OS and has a low hazard potential with a condition assessment of "Not Rated." Despite not being regulated by the state, the dam has not been rated for its emergency action plan or risk management measures. With a maximum discharge of 2400 cubic feet per second, Lake Wilson Dam provides a picturesque setting for water and climate enthusiasts to enjoy outdoor recreation activities in Arkansas.
Owned by a private entity, the dam does not have any associated structures or federal agency involvement in its funding, construction, or regulatory oversight. The Vicksburg District oversees its operations, and the dam has not been inspected or rated for its emergency preparedness. As a vital water resource in the area, Lake Wilson Dam continues to be a focal point for recreational activities and serves as a reminder of the importance of sustainable water management practices in the face of changing climate 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.
