Summary

Charles, Missouri, Klondike Lake Dam stands as a testament to human ingenuity and engineering prowess. Completed in 1965, this private-owned earth-type dam primarily serves the purpose of recreation, offering a serene oasis for water resource and climate enthusiasts to enjoy. With a structural height of 50 feet and a length of 720 feet, this impressive structure boasts a storage capacity of 292 acre-feet and covers a surface area of 19 acres.

The dam's low hazard potential and satisfactory condition assessment make it a safe and reliable water management infrastructure. Managed by the DAM AND RESERVOIR SAFETY PROG in Missouri, Klondike Lake Dam is equipped with an uncontrolled spillway with a width of 66 feet to handle maximum discharge of 465 cubic feet per second. Despite its moderate risk assessment, the dam has undergone regular inspections, with the last one conducted in March 2015, ensuring its operational integrity and safety for both the environment and nearby communities.

For water resource and climate enthusiasts, Klondike Lake Dam offers a fascinating glimpse into the intersection of human innovation and environmental stewardship. Its strategic location in the TRIB MISSOURI RIVER watershed, along with its recreational focus and commitment to safety and regulatory compliance, make it a noteworthy landmark in the region. As water management continues to be a critical issue in the face of climate change, Klondike Lake Dam stands as a beacon of responsible infrastructure development and sustainable resource utilization.

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.
