Summary

Built in 1976 by the USDA NRCS, this earth dam stands at a height of 30 feet and has a length of 1450 feet. Its primary purpose is flood risk reduction, with a storage capacity of 811.04 acre-feet and a drainage area of 1.8 square miles.

Managed by the Kansas Department of Agriculture, Frd No 10 is regulated, permitted, inspected, and enforced by the state. Despite being classified as having a low hazard potential, the dam is considered to have a moderate risk level, with a moderate risk assessment score of 3. It has an uncontrolled spillway, a spillway width of 40 feet, and a maximum discharge capacity of 237 cubic feet per second.

While the dam's condition assessment is currently not rated, it is important to note that Frd No 10 plays a crucial role in mitigating flood risks in the area. As water resource and climate enthusiasts, understanding the infrastructure and management of dams like Frd No 10 is essential in protecting communities and natural resources from the impacts of extreme weather events and changing climate patterns.

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.
