Summary
Built in 1963 by the USDA NRCS, this earth dam stands at a height of 42.6 feet and serves the primary purpose of flood risk reduction along the White Clay Creek-TR river. With a hydraulic height of 52 feet and a structural height of 57 feet, the dam has a storage capacity of 216 acre-feet and covers a surface area of 5.6 acres.
This dam is crucial for protecting the surrounding area from potential flooding, as it is regulated and inspected by the Kansas Department of Agriculture. With a high hazard potential but a satisfactory condition assessment, Frd No 4 demonstrates the importance of ongoing maintenance and monitoring to ensure its continued effectiveness. The dam has a history of regular inspections, with the last one conducted in April 2019.
As water resource and climate enthusiasts, understanding the significance of structures like Frd No 4 in mitigating flood risks and safeguarding communities is essential. With its sturdy earth construction and designed purpose, this dam plays a crucial role in managing water flow and protecting the residents of Atchison from potential disasters. As climate change continues to impact weather patterns and increase the frequency of extreme events, the importance of maintaining and monitoring such infrastructure becomes even more apparent.

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.
