Summary

Built with a primary purpose of flood risk reduction, this earth dam stands at a height of 28 feet and stretches over 700 feet in length. With a capacity for 166 acre-feet of water storage, the dam plays a vital role in debris control and flood risk mitigation in the region.

Despite being designated as low hazard potential, Detention Dam No 133 is considered to have a moderate risk level. The dam, constructed with a buttress core type, features an uncontrolled spillway with a width of 40 feet. Although last inspected in 1996, the overall condition of the dam remains unrated. With no outlet gates and a drainage area of 0.36 square miles, the dam continues to serve as a key infrastructure for managing water resources in Jackson County, Kansas.

As water resource and climate enthusiasts, understanding the significance of Detention Dam No 133 in mitigating flood risks and ensuring water management in the region is crucial. With a focus on flood risk reduction and debris control, this earth dam stands as a testament to effective water resource infrastructure in the face of changing climate patterns. Moving forward, continued monitoring and maintenance of the dam will be essential to uphold its critical role in safeguarding the community against potential water-related 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.
