Summary
Built in 1964 by USDA NRCS, this earth dam stands at a height of 37 feet and serves the primary purpose of flood risk reduction in the Walnut Creek-TR river/stream system. With a storage capacity of 281.2 acre-feet and a surface area of 10.44 acres, Frd No Gs 21 plays a vital role in mitigating potential flood hazards in the area.
This dam, designed as an earth buttress structure, has a moderate risk assessment rating of 3 out of 5, with a low hazard potential. Although the condition assessment is currently not rated, the dam has not reported any significant issues or concerns. The spillway type is uncontrolled with a width of 40 feet, and there are no outlet gates associated with the structure. Despite its age, Frd No Gs 21 continues to operate efficiently, ensuring the safety and protection of the surrounding community from potential flood events.
Overall, Frd No Gs 21 stands as a testament to effective water resource management and climate resilience efforts in Brown County, Kansas. With its strategic location, sound design, and regular regulatory oversight, this dam exemplifies the importance of infrastructure for flood risk reduction in safeguarding communities and ecosystems against the impacts of extreme weather events. As water resource and climate enthusiasts, the data on Frd No Gs 21 serves as a reminder of the critical role that such structures play in promoting sustainability and resilience in the face of changing environmental 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.
