Summary
Charles, Missouri, is a private earth dam completed in 1972 for the primary purpose of flood risk reduction. The dam stands at 25 feet high and stretches 600 feet in length, with a storage capacity of 195 acre-feet. It is situated on the TR-SEHRT Creek and is managed by the Kansas City District of the US Army Corps of Engineers.
Despite being classified as having a significant hazard potential, Sadler Lake Dam is currently in a not rated condition. It does not fall under state jurisdiction or regulation, with no state permitting, inspection, or enforcement requirements in place. The dam serves multiple purposes, including flood risk reduction, fish and wildlife pond, and recreation, making it a valuable asset to the local community.
For water resource and climate enthusiasts, Sadler Lake Dam presents an interesting case study of a privately owned dam with a moderate risk assessment. With its uncontrolled spillway and significant storage capacity, the dam plays a crucial role in managing flood risks in the region. Further research into its condition assessment, emergency action plan, and risk management measures could provide valuable insights into the resilience of such infrastructure in the face of changing environmental conditions.

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.
