Summary
The dam, classified as an Earth type with a buttress core, stands at a height of 20 feet and has a storage capacity of 96 acre-feet. With a surface area of 9 acres and a drainage area of 23 square miles, the dam plays a crucial role in managing water resources in the region.
Owned privately, Lenz Lake Dam is not regulated by the state and has a low hazard potential. Despite not being rated for condition assessment, the dam continues to support irrigation activities in the area. The dam's location on the TR-Clark Fork-Petite Saline Creek contributes to water management and agricultural activities in Cooper County, Missouri. As a key infrastructure for water management, the dam showcases the importance of sustainable water resource management practices in the face of changing climate conditions.
Although not federally owned or funded, Lenz Lake Dam plays a vital role in irrigation and water resource management in the region. As an essential piece of infrastructure, the dam supports agricultural activities and contributes to the overall water management efforts in Cooper County. With its low hazard potential and unlisted foundations, the dam stands as a testament to the importance of private ownership in maintaining and managing water resources effectively.

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.
