Summary
Completed in 1973, this earth dam with stone core types rises 42 feet high and spans 900 feet in length, holding a maximum storage capacity of 645 acre-feet. The dam's primary purpose also includes providing fire protection and serving as a small fish pond, showcasing its multifunctional role in managing water resources in the region.
Despite its age, Magee Lake Dam maintains a satisfactory condition assessment as of December 2007, with inspections conducted every three years to ensure its structural integrity and safety. With a high hazard potential, the dam is regulated, permitted, inspected, and enforced by the Dam and Reservoir Safety Program in Missouri, showcasing a commitment to maintaining the safety of the surrounding community. While the risk assessment categorizes the dam as moderate, risk management measures are not explicitly outlined, presenting an opportunity for further enhancement and preparedness in the face of changing climate conditions. Magee Lake Dam stands as a testament to effective water resource management and climate resilience efforts in Missouri.

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.
