Summary

This dam stands at a height of 34 feet and has a length of 7960 feet, providing a storage capacity of 2491 acre-feet and covering a surface area of 45 acres. With a drainage area of 6.21 square miles, Frd No 6 has a maximum discharge capacity of 3395 cubic feet per second and features an uncontrolled spillway with a width of 125 feet.

Managed by the Kansas Department of Agriculture and regulated by the state, Frd No 6 has a low hazard potential and a moderate risk assessment rating of 3. While currently not rated in terms of condition assessment, this dam has not undergone any modifications and does not have an emergency action plan in place. Despite its low hazard potential, Frd No 6 serves a vital role in mitigating flood risks in the region and highlights the importance of proper dam maintenance and emergency preparedness in water resource management and climate resilience efforts.

For water resource and climate enthusiasts, Frd No 6 serves as a prime example of a local government-owned structure designed to address flood risk reduction in Butler County, Kansas. With its strategic location along Maple Creek and its significant storage capacity, this earth dam plays a critical role in safeguarding the surrounding area from potential flooding events. As climate change continues to impact water resources and weather patterns, the management and maintenance of dams like Frd No 6 become increasingly important in ensuring the safety and resilience of communities against natural disasters.

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.
