Summary

Completed in 1994, this dam stands at a height of 29.5 feet and has a storage capacity of 306.6 acre-feet. With a spillway width of 50 feet and a maximum discharge of 1200 cubic feet per second, Dd No 104 plays a critical role in managing water flow and reducing flood risks in the area.

Despite its low hazard potential, Dd No 104 is regulated by the Kansas Department of Agriculture and undergoes regular inspections, permitting, and enforcement to ensure its structural integrity. The dam's primary purpose is debris control and flood risk reduction, serving the community by protecting against potential inundation in times of high water levels. With a moderate risk assessment rating of 3, Dd No 104 is a key component of the local water resource management infrastructure, demonstrating the importance of proactive risk management in preserving the region's water supply and climate resilience.

As a vital piece of the Kansas City District's flood control system, Dd No 104 highlights the collaborative efforts between local and state agencies to safeguard water resources and mitigate potential hazards. With its strategic location and design features, this earth dam stands as a testament to the engineering expertise and commitment to environmental protection in the region. By upholding stringent regulatory standards and implementing risk management measures, Dd No 104 serves as a model for sustainable water infrastructure development in the face of changing climate conditions.

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.
