Summary
Built in 1964 by the USDA NRCS, this earth dam stands at a height of 49.3 feet and serves the primary purpose of flood risk reduction along the White Clay Creek-TR river or stream. With a storage capacity of 617 acre-feet and a drainage area of 0.61 square miles, Frd No 11 plays a vital role in mitigating the impact of potential flooding events in the region.
Managed by the KS Dept. of Agriculture and regulated by the state, Frd No 11 has a high hazard potential but is currently assessed to be in satisfactory condition. The dam's structure includes buttress core types and a spillway width of 33 feet. Despite not having any associated structures, Frd No 11 is subject to regular inspections, with the last one conducted in April 2019. With its location in Atchison and its critical role in managing flood risks, this dam is a key component of the region's water resource and climate resilience infrastructure.
Overall, Frd No 11 represents a significant investment in flood risk reduction in Atchison, Kansas. With its solid construction by the USDA NRCS and ongoing regulatory oversight, this earth dam provides essential protection for the surrounding area against potential inundation events. As climate change continues to impact water resources and weather patterns, structures like Frd No 11 will play an increasingly crucial role in safeguarding communities and infrastructure from the threats of flooding and water-related emergencies.

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.
