Summary

Completed in 1964 by the US Army Corps of Engineers, this gravity dam stands at a height of 87 feet and has a length of 21,790 feet, serving primarily for flood risk reduction. With a maximum storage capacity of 626,007 acre-feet and a normal storage of 60,661 acre-feet, the dam plays a crucial role in managing water levels and mitigating flood risks in the region.

As a high hazard potential dam, John Redmond Dam is subject to regular inspections and risk assessments to ensure its structural integrity and safety. The US Army Corps of Engineers implements various risk management measures, including continuous monitoring, maintenance, and collaboration with local emergency managers to develop emergency action plans and evacuation procedures. Despite the challenges posed by severe weather events and potential overflows, the Corps remains dedicated to safeguarding the dam and the surrounding communities from the impacts of flooding through proactive risk reduction strategies.

With a comprehensive approach to dam safety and risk management, John Redmond Dam stands as a critical infrastructure asset in protecting the Coffey County area from the threats of flooding. By prioritizing maintenance, monitoring, and emergency preparedness, the US Army Corps of Engineers continues to uphold the dam's functionality and resilience in the face of evolving climate conditions and potential hazards.

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.
