Summary
With a height of 50 feet and a storage capacity of 2190 acre-feet, this dam serves the purpose of flood control and water storage for the surrounding area. The dam's structure is primarily composed of stone with a soil foundation, making it a resilient and reliable asset in the region's water resource management.
State-regulated and inspected for safety and enforcement by the DAM and Reservoir Safety Program, Maple Leaf Lake Dam boasts a satisfactory condition assessment as of December 2007. With a significant hazard potential and moderate risk assessment rating, the dam's emergency action plan preparation and guidelines adherence are areas that require attention and further development. Despite these challenges, the dam's design, construction, and operation align with state permitting and regulatory standards, ensuring its critical role in maintaining water resources and climate resilience in the region.
Managed by the Kansas City District of the US Army Corps of Engineers, Maple Leaf Lake Dam's uncontrolled spillway and valve outlet gates contribute to its effective water discharge capabilities. With a drainage area of 1650 acres and a maximum discharge rate of 12,161 cubic feet per second, the dam plays a vital role in managing water levels and mitigating flood risks in Lafayette, Missouri. For water resource and climate enthusiasts, Maple Leaf Lake Dam stands as a notable landmark in the region's water infrastructure, showcasing the importance of sustainable dam management practices in ensuring community safety and environmental resilience.

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.
