Summary
Completed in 1925, this earth dam stands at a height of 25 feet and has a storage capacity of 134 acre-feet. With a normal storage level of 65 acre-feet, the dam serves the purpose of providing recreational opportunities in the area.
Situated on the TR to Meramec River, Cedar Lake Dam is under the jurisdiction of the Kansas City District. Despite its low hazard potential and a lack of state regulation, the dam has not been inspected or rated for its condition. The structure has not undergone any modifications over the years and lacks emergency action plans or inundation maps. With its historical significance and recreational importance, Cedar Lake Dam stands as a picturesque landmark in Franklin County, Missouri.
For water resource and climate enthusiasts, Cedar Lake Dam offers a unique opportunity to explore the intersection of human-made infrastructure and natural ecosystems. With its serene surroundings and potential for outdoor activities, the dam serves as a valuable resource for the local community. However, the lack of regulatory oversight and maintenance raises questions about the long-term sustainability of the structure in the face of changing climate conditions and increased pressure on water resources. As efforts to address these challenges continue, Cedar Lake Dam remains a symbol of both the benefits and risks associated with human interventions in the natural world.

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.
