Summary

Constructed in 1975, this privately owned earth dam serves primarily for recreational purposes, offering a serene escape for nature enthusiasts and water sports aficionados alike. Spanning 600 feet in length and reaching a height of 42 feet, the dam harnesses the waters of the Little Bonne Femme Creek to create a reservoir that covers 21 acres and boasts a storage capacity of 302 acre-feet.

Despite its tranquil appearance, Cedar Lake Dam is subject to rigorous state regulations and inspections to ensure public safety. Classified as having a high hazard potential, the dam is closely monitored by the Dam and Reservoir Safety Program in Missouri. Despite this classification, the condition assessment of the dam as of 2007 was deemed satisfactory, with a moderate risk level assigned. Emergency action plans are in place, and regular inspections are conducted to mitigate any potential risks and ensure the structural integrity of the dam for years to come. For water resource and climate enthusiasts, Cedar Lake Dam presents a unique blend of natural beauty and human ingenuity, making it a must-visit destination for those interested in the intersection of water management and recreation.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
