Summary

Built in 1969 by the USDA NRCS, this earth dam stands at a height of 27 feet and serves the primary purpose of flood risk reduction in the Nicholas Creek watershed. With a storage capacity of 425.52 acre-feet and a normal storage of 27.1 acre-feet, Frd No 10 plays a vital role in managing water flow and protecting downstream areas from potential flooding events.

Managed by the local government and regulated by the Kansas Department of Agriculture, Frd No 10 has been deemed to have a low hazard potential with a moderate risk assessment rating. The dam features an uncontrolled spillway with a width of 40 feet and serves a drainage area of 0.98 square miles. While the dam's condition is currently not rated, it undergoes regular state inspections to ensure its structural integrity and operational effectiveness. With its strategic location in Leon, Kansas, Frd No 10 stands as a testament to effective water resource management and climate resilience efforts in the region.

Overall, Frd No 10 stands as a critical piece of infrastructure in the Kansas City District, providing essential flood risk reduction services and water management capabilities for the local community. As a key component in the Nicholas Creek watershed, this earth dam underscores the importance of proactive water resource planning and climate adaptation measures in safeguarding against potential environmental risks. With its low hazard potential and moderate risk assessment, Frd No 10 exemplifies the collaborative efforts between local government agencies and the USDA NRCS in ensuring the safety and resilience of water infrastructure in Butler County, Kansas.

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.
