Summary

Owned by the local government and designed by USDA NRCS, this dam serves the primary purpose of mitigating flood risks in the area. With a dam height of 44 feet and a storage capacity of 560 acre-feet, Frd No 13 plays a crucial role in protecting the community from potential flooding events.

Situated on Lyon Creek-TR in Dickinson County, Kansas, Frd No 13 is regulated by the Kansas Department of Agriculture and undergoes state permitting, inspection, and enforcement. The dam, constructed with an earth core and buttress type, spans a length of 1610 feet and covers a surface area of 10.6 acres. With a low hazard potential and a moderate risk assessment rating, Frd No 13 is considered a vital infrastructure for water resource management in the region.

Although the dam's condition is currently not rated, Frd No 13 is an essential component of the flood control system in Lyona, Kansas. With its strategic location and design, this dam ensures the safety and well-being of the local community by reducing the risk of flooding and safeguarding the surrounding area from potential water-related disasters.

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.
