Summary
Completed in 1974, this earth dam stands at a height of 33 feet and has a storage capacity of 358.43 acre-feet. Situated on the Black Vermillion River, this dam plays a crucial role in protecting the surrounding area from potential flooding events.
Managed by the Kansas Department of Agriculture, Frd No 26 is regulated, inspected, and enforced by state authorities to ensure its structural integrity and functionality. With a moderate risk assessment rating, this dam has a low hazard potential and is currently deemed to be in not rated condition. The spillway, categorized as uncontrolled, has a width of 40 feet, and the dam itself spans a length of 950 feet. Despite its low hazard potential, this structure remains a vital component in the overall flood risk reduction strategy for the region.
Located in Marshall County, Kansas, Frd No 26 provides valuable flood protection for the community and surrounding areas. As part of the flood risk reduction system, this dam contributes to the overall water resource management efforts in the region, demonstrating the importance of infrastructure in mitigating the impacts of extreme weather events and climate change. With its moderate risk assessment and low hazard potential, Frd No 26 stands as a testament to the collaborative efforts between local and state agencies to safeguard water resources and enhance climate resilience in the area.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
