Summary

This dam, designed by DELAWARE WJD NO. 10, stands at a height of 32 feet and stretches for 600 feet, with a storage capacity of 212.9 acre-feet. The dam serves to reduce flood risks and protect the surrounding area from potential hazards, making it an essential structure for water resource management in the region.

With a low hazard potential and a moderate risk assessment rating, Gs Dd No C-129 plays a crucial role in maintaining the safety and stability of the area. Although its condition assessment is currently not rated, the dam is regulated, permitted, inspected, and enforced by the Kansas Department of Agriculture, ensuring that it meets all necessary safety standards and guidelines. The dam's location at 25,6S, 13E further highlights its significance in the local water resource and climate resilience efforts.

Despite not having undergone recent modifications or inspections, Gs Dd No C-129 continues to serve its purpose effectively, with a spillway width of 70 feet and a maximum discharge capacity of 1773 cubic feet per second. As water resource and climate enthusiasts, it is important to recognize the vital role that structures like Gs Dd No C-129 play in safeguarding communities and ecosystems from the impacts of extreme weather events and ensuring sustainable water management practices for the future.

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.
