Summary
Built in 1965 by USDA NRCS, this earth dam stands at a height of 44.6 feet and serves the primary purpose of flood risk reduction along the White Clay Creek-TR. With a storage capacity of 138 acre-feet and a surface area of 3.79 acres, Frd No 20 plays a crucial role in mitigating potential hazards in the area.
Managed by the Kansas Department of Agriculture, Frd No 20 is subject to state regulations, inspections, and enforcement to ensure its structural integrity and overall safety. With a satisfactory condition assessment and a high hazard potential, regular inspections are conducted to monitor its performance. Despite its age, Frd No 20 continues to meet guidelines for emergency action plans and risk management measures, highlighting its importance in safeguarding the local community from potential flooding events.
As part of the Rock Island District, Frd No 20 is a vital component of the local water resource infrastructure, providing essential flood protection for the surrounding area. With its strategic location and design features, this earth dam remains an essential asset for the City of Atchison and the state of Kansas in managing water resources and climate-related risks.

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.
