Summary

Completed in 1970, this earth dam stands at 36 feet in height and spans 1700 feet in length, providing a storage capacity of 1752.51 acre-feet to help manage the flow of Dutch Creek-TR during periods of heavy rainfall.

Situated in the city of Winfield, Frd No 26 is owned by the local government and regulated by the Kansas Department of Agriculture. With a low hazard potential and a moderate risk assessment rating of 3, this dam has not been inspected since 1979 and is currently not rated for its condition. Despite its age, Frd No 26 continues to serve its primary purpose of flood risk reduction, showcasing the importance of regular maintenance and inspection to ensure its long-term effectiveness in protecting the surrounding area from potential disasters.

As a key infrastructure in the region, Frd No 26 plays a crucial role in water resource management and climate resilience efforts. With its uncontrolled spillway, this dam has a maximum discharge capacity of 520 cubic feet per second, offering vital protection to the local community in times of extreme weather events. Moving forward, continued monitoring and investment in maintenance will be essential to uphold the integrity and functionality of Frd No 26 for years to come, safeguarding the community against future flood risks and ensuring the sustainable management of water resources in the region.

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.
