Summary

This earth-type dam stands at a height of 31.7 feet with a structural height of 60 feet and a length of 1300 feet. With a maximum storage capacity of 732 acre-feet and a normal storage level of 90 acre-feet, the dam serves to mitigate flood risks in the area.

Managed by the Kansas Department of Agriculture, the dam is state-regulated, permitted, inspected, and enforced to ensure its safety and functionality. Despite its low hazard potential, the dam's condition assessment is not rated, and additional risk management measures may be needed to address any potential vulnerabilities. Although the dam does not fall under USACE jurisdiction, its design and purpose highlight the importance of water resource management and climate adaptation efforts in safeguarding communities from flooding events.

As a critical infrastructure asset in the region, Storer Detention Dam plays a crucial role in protecting the surrounding area from flood risks. With its strategic location and design, the dam serves as a vital tool in water resource management, showcasing the collaborative efforts between private owners, government agencies, and design experts in addressing climate-related challenges. Moving forward, continued monitoring and maintenance of the dam will be essential to ensure its long-term effectiveness in mitigating flood hazards and safeguarding the community against water-related 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.
