Summary

Built in 2000, this earth dam stands at a height of 18 feet and stretches 1200 feet in length, with a storage capacity of 306.16 acre-feet. Although the dam is classified as low hazard potential, it is regulated, inspected, and enforced by the Kansas Department of Agriculture to ensure its structural integrity and public safety.

Managed by the Tulsa District of the US Army Corps of Engineers, Dd No K-6 has a spillway width of 40 feet and a maximum discharge capacity of 1042 cubic feet per second. The dam's normal storage volume is 23.14 acre-feet, covering a surface area of 8.21 acres in Bourbon County, Kansas. Despite being unlisted for specific foundations, the dam's core type is identified as buttress, contributing to its overall stability and flood control capabilities.

With a moderate risk assessment rating of 3, Dd No K-6 is actively monitored for any necessary risk management measures to address potential threats to its integrity. The dam's emergency action plan status, condition assessment, and compliance with regulatory guidelines are all areas of ongoing evaluation to ensure its operational readiness and effectiveness in flood mitigation efforts.

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.
