Summary
Completed in 1974, this earth dam stands at a height of 15 feet and has a storage capacity of 104 acre-feet. It is situated on TR McCoy Creek in St. Charles County and covers a drainage area of 530 square miles. Despite its low hazard potential, the dam's condition assessment is currently listed as "Not Rated."
Managed by the Kansas City District of the US Army Corps of Engineers, Carlie Lake Dam has not been regulated or inspected by the state of Missouri. With a surface area of 13 acres and a normal storage capacity of 56 acre-feet, this dam provides a serene setting for recreational activities such as fishing and boating. While the dam's emergency action plan status is unknown, its risk management measures and inundation maps have not been prepared or updated. Overall, Carlie Lake Dam presents a unique opportunity for water resource and climate enthusiasts to explore and appreciate the beauty of this man-made structure within the natural landscape of St. Charles County.

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.
