Summary
Completed in 1976, this Earth-type dam boasts a height of 30 feet and a length of 475 feet, providing essential storage capacity for the surrounding area. With a normal storage capacity of 78 acre-feet and a maximum storage of 138 acre-feet, Legion Lake Dam plays a crucial role in managing water resources in the region.
Situated on TR-CINQUE HOMMES CREEK, Legion Lake Dam is owned by the local government and falls under the jurisdiction of Missouri. Despite its low hazard potential, the dam has not been rated for its condition assessment. With a moderate risk assessment rating, there is a need for continued monitoring and risk management measures to ensure the safety and integrity of the structure. As a hub for recreation and wildlife support, Legion Lake Dam serves as a testament to the intersection of water resource management and environmental conservation efforts in the region.
With its uncontrolled spillway and moderate risk assessment, Legion Lake Dam stands as a testament to the delicate balance between human development and environmental stewardship. As water resource and climate enthusiasts explore the intricacies of this structure, its role in supporting fish and wildlife habitats while providing recreational opportunities becomes increasingly apparent. Legion Lake Dam serves as a reminder of the importance of sustainable water management practices in the face of changing climate and environmental 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.
