Summary
Constructed in 1978 by the USDA NRCS, this earth dam stands at a height of 38 feet and serves the primary purpose of flood risk reduction along the Elk Creek-TR river or stream. With a storage capacity of 123.79 acre-feet and a moderate hazard potential rating, this structure plays a crucial role in mitigating flood risks in the area.
Managed by the Kansas Department of Agriculture, Dd No C-56 is regulated, permitted, inspected, and enforced by state agencies to ensure its safety and functionality. With a spillway width of 94 feet and a maximum discharge capacity of 423 cubic feet per second, this dam is designed to handle excess water during heavy rainfall events. Despite its low hazard potential, the dam's condition assessment is currently listed as "Not Rated," indicating a need for further evaluation and maintenance to uphold its effectiveness in flood risk reduction.
As a key element in the flood control infrastructure of Jackson County, Kansas, Dd No C-56 (King) serves as a vital component in protecting the surrounding communities from potential inundation. With its strategic location, design features, and state oversight, this dam contributes to the overall resilience of the region against the impacts of extreme weather events and climate variability. For water resource and climate enthusiasts, understanding the significance of this structure sheds light on the intersection of infrastructure, environmental protection, and community safety in the face of changing climate conditions.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
