Summary
With a height of 28 feet and a storage capacity of 105 acre-feet, this dam is situated on the TR-AUXVASSE CREEK, providing a serene and picturesque setting for water resource and climate enthusiasts to enjoy. Despite its low hazard potential and the condition being rated as "Not Rated", the dam has not been inspected or assessed in recent years.
Owned and operated privately, Leisure Lake Dam-South offers a surface area of 7 acres and a normal storage capacity of 51 acre-feet, making it an ideal spot for outdoor activities and water sports. The dam's construction year and specific spillway type are not listed, but its location in PORTLAND, Missouri, makes it easily accessible for visitors seeking a tranquil escape in the heart of nature. While the dam has not been subject to regular inspections or maintenance, its risk assessment and emergency action plan status remain unknown, raising questions about its long-term reliability and safety measures.
In the absence of state regulation or oversight, the future maintenance and sustainability of Leisure Lake Dam-South may raise concerns for water resource and climate enthusiasts. With the dam's emergency preparedness and risk management measures still unclear, it is essential for private owners to prioritize regular inspections and maintenance to ensure the safety and integrity of this recreational structure in the face of potential climate-related challenges.

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.
