Summary
Built in 1971 by the USDA NRCS, this earth dam stands at a height of 28.8 feet and serves primarily for flood risk reduction along the Irish Creek-TR stream. With a storage capacity of 264.66 acre-feet and a surface area of 9.82 acres, Frd No 56 plays a critical role in managing water resources in the region.
Managed by the Kansas Department of Agriculture, this dam is regulated, permitted, inspected, and enforced by state agencies to ensure its safety and functionality. The spillway width of 40 feet and uncontrolled spillway type contribute to its low hazard potential, while the moderate risk assessment rating indicates a need for ongoing risk management measures. Although the condition assessment is currently not rated, Frd No 56 remains an essential infrastructure for flood control and water resource management in Marshall County, Kansas.
Overall, Frd No 56 exemplifies the collaboration between local and federal agencies in addressing water resource challenges. Its strategic location and design highlight the importance of sustainable infrastructure for climate resilience. As water resource and climate enthusiasts, understanding the role of structures like Frd No 56 is crucial in promoting effective water management practices and mitigating the impacts of extreme weather events in the region.

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.
