Summary
This privately owned earth dam stands at a height of 25 feet, with a storage capacity of 401 acre-feet and a surface area of 30 acres. Despite its low hazard potential and not being state regulated, the dam provides essential water storage for the surrounding Shelby County community.
With a primary purpose of recreation, Wilson South Lake Dam offers opportunities for fishing, boating, and other outdoor activities in the tranquil setting of its namesake lake. Its buttress core design ensures structural stability and safety for visitors. The dam is situated on the TR to Tenmile Creek, within the St. Louis District of the US Army Corps of Engineers, and falls under the jurisdiction of Congressman Sam Graves (R).
While the dam's condition remains unrated, its contribution to the local environment and economy is undeniable. As climate change impacts water resources, the importance of maintaining and monitoring dams like Wilson South Lake Dam becomes increasingly crucial. With its picturesque location and recreational value, this dam stands as a testament to the balance between human enjoyment and environmental stewardship in water resource management.

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.
