Summary

Completed in 1986, this earth dam stands at a height of 37 feet and spans 670 feet in length, serving primarily for flood risk reduction and debris control along Banner Creek. With a storage capacity of 239.6 acre-feet, the dam has a low hazard potential and is regulated by the Kansas Department of Agriculture.

The dam features an uncontrolled spillway with a width of 62 feet and a maximum discharge of 1604 cubic feet per second. Despite being classified as having a moderate risk level, Gs Dd No C-48 is not currently rated for its condition assessment. Emergency action plans and risk management measures are not specified, indicating potential areas for improvement in preparedness and response protocols. Overall, this dam plays a crucial role in mitigating flood risks in the area and highlights the importance of ongoing monitoring and maintenance for water resource management in Kansas.

As water resource and climate enthusiasts, understanding the infrastructure and regulatory framework of dams like Gs Dd No C-48 is essential for assessing their impact on local communities and ecosystems. By staying informed about the design, purpose, and condition of such structures, stakeholders can advocate for sustainable water management practices and ensure the safety and resilience of these critical assets 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.
