Summary
Built in 1965 by the USDA NRCS, this earth dam stands at a height of 33 feet and serves the primary purpose of flood risk reduction in the Spring Creek-TR river or stream. With a normal storage capacity of 29 acre-feet and a drainage area of 0.48 square miles, Frd No Gs 20 plays a crucial role in mitigating potential flood hazards in the region.
Despite being classified as a low hazard potential dam, Frd No Gs 20 is regulated by the state of Kansas Department of Agriculture and undergoes regular inspections to ensure its structural integrity. The dam features an uncontrolled spillway with a width of 40 feet and does not have outlet gates. With a risk assessment rating of moderate (3), the dam is continuously monitored for any potential risks or maintenance needs to uphold its flood risk reduction function effectively.
Even though the condition assessment of Frd No Gs 20 is currently marked as "Not Rated," the dam remains an essential piece of infrastructure for the local community in preventing flood damages and protecting the surrounding area from potential inundation events. As climate change continues to impact water resources and weather patterns, structures like Frd No Gs 20 play a vital role in safeguarding communities and enhancing resilience against the evolving challenges posed by a changing climate.

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.
