Summary

Built in 1991, this earth dam stands at a height of 32 feet and spans a length of 2100 feet, with a storage capacity of 1282 acre-feet. Despite its low hazard potential, the dam is regulated by the Kansas Department of Agriculture and undergoes regular inspections to ensure its structural integrity and functionality.

Owned and operated by the local government, Frd No 4 is designed to withstand moderate risk levels and is equipped with an uncontrolled spillway with a width of 40 feet to manage excess water flow during heavy rainfall events. The dam's primary purpose is flood risk reduction, reflecting its crucial role in protecting the surrounding area from potential inundation. With a drainage area of 3.04 square miles, the dam covers a surface area of 24.6 acres and has a normal storage level of 105.1 acre-feet, highlighting its significance in water resource management in the region.

Overall, Frd No 4 stands as a testament to the collaborative efforts between local and state agencies in ensuring the safety and resilience of the community against natural disasters. With its strategic location and design features, this dam plays a vital role in safeguarding both property and lives from the impacts of flooding, showcasing the importance of reliable water infrastructure in mitigating climate-related risks.

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.
