Summary

Managed by the local government, this earth dam stands at a height of 33.7 feet and stretches 1305 feet in length, providing essential protection to the surrounding area from potential flooding events. With a storage capacity of 511.9 acre-feet and a drainage area of 1.38 square miles, Frd No 6 plays a crucial role in managing water resources in the region.

Constructed by the USDA NRCS, Frd No 6 is regulated by the Kansas Department of Agriculture and undergoes regular inspections to ensure its structural integrity. While considered to have a low hazard potential, the dam is evaluated to have a moderate risk level, highlighting the importance of ongoing risk management measures. With a spillway width of 40 feet and a maximum discharge capacity of 1147.9 cubic feet per second, Frd No 6 is well-equipped to handle excess water flow and protect the community it serves.

Overall, Frd No 6 stands as a key component in the local water resource management system, serving its primary purpose of flood risk reduction effectively. With its strategic location along the Phenis Creek-TR stream, this earth dam not only safeguards the area from potential flooding but also contributes to the overall resilience of the region in the face of changing climate patterns. As water resource and climate enthusiasts, understanding the vital role of structures like Frd No 6 is essential in promoting 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.
