Summary

Completed in 1935, this earth dam on Spring Creek serves multiple purposes including flood risk reduction, fish and wildlife habitat, and recreation. With a height of 41 feet and a length of 1680 feet, the dam has a normal storage capacity of 950 acre-feet and a maximum discharge capability of 15,854 cubic feet per second.

Despite being classified as having a low hazard potential, Anthony City Dam is regulated and inspected by the Kansas Department of Agriculture. The dam features an uncontrolled spillway with a width of 305 feet and has not been modified in recent years. The risk assessment for the dam is moderate, with a DSAC risk rating of 3, indicating a need for ongoing monitoring and management measures to ensure its continued safety and functionality.

Even though the condition of Anthony City Dam is not currently rated, its recreational value and role in flood risk reduction make it a vital structure in the Harper County water resource management system. With its historical significance and strategic location, the dam continues to be a focal point for water resource and climate enthusiasts in the region.

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.
