Summary

Completed in 1964, this earth dam stands at a height of 27 feet and has a hydraulic height of 24 feet, offering flood risk reduction for the Halderman Creek-TR stream. With a storage capacity of 848.35 acre-feet and a normal storage capacity of 65 acre-feet, Frd No 9-4 plays a vital role in protecting the surrounding community.

The dam, with a length of 1350 feet and a surface area of 13.43 acres, is regulated by the Kansas Department of Agriculture and undergoes regular inspections to ensure its structural integrity. Despite being classified as having a low hazard potential, the dam is rated as moderately risky due to its age and the potential impact of a failure. The presence of an uncontrolled spillway with a width of 40 feet adds to the dam's risk factor, highlighting the importance of ongoing risk management measures to safeguard the area from potential disasters.

While Frd No 9-4 currently does not have an emergency action plan in place, its risk assessment and condition are regularly evaluated to ensure the safety of the surrounding communities. With its strategic location in the Greenwood County of Kansas, this dam serves as a critical infrastructure for flood control and water resource management in the region, emphasizing the essential role it plays in maintaining the resilience of the local ecosystem in the face of changing climate conditions.

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.
