Summary
Charles, Missouri, is a privately owned structure that serves as a recreational hub for water and climate enthusiasts. Completed in 1995, this Earth dam stands at a height of 61 feet and has a length of 230 feet, providing a storage capacity of 12 acre-feet and a surface area of 2 acres. The dam is situated along the TR to Missouri River and is under the regulatory jurisdiction of the DAM AND RESERVOIR SAFETY PROG in Missouri.
With a hazard potential rated as high and a satisfactory condition assessment, De Villa Trails Lake Dam is subject to regular inspections, with the last one conducted in August 2017. The dam features an uncontrolled spillway with a width of 8 feet and a maximum discharge of 360 cubic feet per second. Despite its moderate risk level, the dam is equipped to handle emergency situations with an Emergency Action Plan (EAP) in place, last revised in November 2010. For water resource and climate enthusiasts, this dam offers a fascinating blend of recreation and safety considerations in a picturesque setting within the Kansas City District.

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.
