Summary
Completed in 1979, this earth dam stands at a height of 41 feet and has a hydraulic height of 36 feet, with a storage capacity of 2230.78 acre-feet. The primary purpose of Frd No 6 is flood risk reduction, serving as a crucial infrastructure in managing water resources in the region.
Situated along Dinner Creek, Frd No 6 is regulated and inspected by the Kansas Department of Agriculture, ensuring its compliance with state standards and safety measures. With a low hazard potential and a moderate risk assessment rating, this dam plays a vital role in protecting the surrounding community from potential flooding events. While not currently rated in terms of condition assessment, Frd No 6 remains an essential component of the local water resource management system, contributing to the overall resiliency of the area in the face of climate variability and extreme weather events.
As part of the Kansas City District, Frd No 6 is a key piece of infrastructure in the region's flood risk reduction strategy. With a spillway width of 200 feet and a maximum discharge capacity of 5066 cubic feet per second, this dam is equipped to handle significant water flow during high precipitation events. While the structure has not been modified in recent years and lacks outlet gates, it continues to serve its intended purpose effectively, safeguarding the community of Leroy and beyond from the adverse impacts of flooding.

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.
