Summary

Built in 2001, this earthen dam stands at a height of 20 feet and stretches for 1000 feet, providing a storage capacity of 100.55 acre-feet. The primary purposes of this dam are for fire protection, stock, and small fish pond, serving the local community's needs.

Managed by the Kansas Department of Agriculture, Dcc - Site 1 is regulated, permitted, inspected, and enforced by the state authorities to ensure compliance with safety standards. The dam has a significant hazard potential, although its condition assessment is currently not rated. Despite the lack of a condition assessment, the dam's last inspection was conducted in November 2006, with a scheduled inspection frequency of every 5 years to monitor its safety and integrity.

With a drainage area of 0.27 square miles and a maximum discharge capacity of 645 cubic feet per second, Dcc - Site 1 plays a crucial role in water resource management and flood control in the region. As a site of interest for water resource and climate enthusiasts, this dam provides valuable insights into the infrastructure and management strategies for maintaining water security and resilience in the face of changing environmental 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.
