Summary

With a height of 40 feet and a length of 1000 feet, this dam has a storage capacity of 663.18 acre-feet and serves the primary purposes of debris control and flood risk reduction. The dam has a fair condition assessment and a significant hazard potential, with a moderate risk assessment rating.

Managed by the local government and regulated by the Kansas Department of Agriculture, Dd No 104 has a spillway width of 160 feet and a maximum discharge capacity of 165 cfs. The dam, designed by Booker Freund & Associates, has a surface area of 10.7 acres and drains a 2.21 square mile watershed. Although the dam currently has no associated structures, it is inspected every 5 years to ensure its structural integrity and safety for the surrounding community.

In the event of an emergency, the dam has emergency action plans in place, but its overall risk management measures and inundation maps are yet to be fully assessed and updated. With its role in flood risk reduction and debris control, Dd No 104 stands as a critical water resource infrastructure in Cowley County, Kansas, providing protection and safety to the local community.

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.
