Summary

With a height of 14.1 feet and a length of 1010 feet, the dam has a storage capacity of 97.48 acre-feet, providing vital protection for the surrounding area. The dam's spillway, with a width of 40 feet, is uncontrolled, and the hazard potential is rated as low.

Despite being classified as low hazard potential, Dd No 219 (King) plays a crucial role in managing flood risks in the region. The dam's purpose is solely for flood risk reduction, with a normal storage capacity of 12.6 acre-feet. Although the condition assessment is listed as "not rated," the risk assessment indicates a moderate risk level (3), prompting the need for ongoing monitoring and management measures to ensure the dam's continued effectiveness in safeguarding the community.

With its strategic location and design by the Soil Conservation Service (SCS), Dd No 219 (King) exemplifies the importance of local infrastructure in mitigating the impact of extreme weather events. As a key component in the flood risk reduction strategy for Woodson County, Kansas, this dam serves as a critical asset in protecting lives and property during periods of heightened climate variability.

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.
