Summary

Completed in 1962, this buttress-type dam stands at a height of 85 feet and has a length of 1570 feet. With a storage capacity of 1400 acre-feet and a drainage area of 800 acres, the dam serves primarily for tailings purposes.

Despite its significant storage capacity and strategic location on TR-Mine A Breton Creek, Gun Club Lake Dam is classified as having a high hazard potential and an unsatisfactory condition assessment. The last inspection in 2010 raised concerns about its safety, prompting a moderate risk assessment rating of 3. While it is regulated and permitted by the state, with regular inspections and enforcement, the dam's condition remains a point of concern for both water resource and climate enthusiasts.

In the event of an emergency, the dam's emergency action plan (EAP) status is undetermined, potentially impacting its ability to meet guidelines and ensure public safety. However, with a maximum discharge capacity of 658 cubic feet per second and a surface area of 60 acres, Gun Club Lake Dam remains a critical structure in the Kansas City District. As efforts continue to monitor and improve its condition, the dam serves as a focal point for ongoing discussions in water resource management and climate resilience.

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.
