Summary
The dam is primarily used for recreation purposes and stands at a height of 25 feet with a storage capacity of 27 acre-feet. It has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. The dam is not state-regulated and does not require regular inspections or state permitting.
Despite its modest size and lack of regulation, Lewis Lake Dam South provides a valuable resource for water enthusiasts in the area. The dam offers a serene location for recreational activities such as fishing, boating, and wildlife watching. Its location in the St. Louis District and proximity to Mcbaine makes it easily accessible for visitors looking to enjoy the beauty of nature in the region.
While Lewis Lake Dam South may not be a major landmark, its significance lies in its contribution to local water resources and the opportunities it provides for outdoor recreation. As a private entity, the dam serves as a reminder of the diverse range of water infrastructure in the region and the importance of maintaining these structures for both functional and leisure purposes.

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.
