Summary
Owned by the local government and designed by USDA NRCS, this earth dam stands at a height of 33 feet and was completed in 1966 for the primary purpose of flood risk reduction. With a normal storage capacity of 27 acre-feet and a drainage area of 1.25 square miles, the dam plays a significant role in managing water resources in the area.
Managed by the Kansas Department of Agriculture, Frd No 20 is regulated, inspected, and enforced by state authorities to ensure its structural integrity and overall safety. The dam's low hazard potential and moderate risk assessment make it a key component of the Rock Creek watershed's flood control system. Despite not being rated for its condition, the dam's emergency action plan and risk management measures are essential for mitigating potential risks and ensuring the safety of nearby communities in Winfield, Kansas.
With a spillway width of 40 feet and an uncontrolled spillway type, Frd No 20 has a maximum storage capacity of 598.47 acre-feet and a surface area of 7.98 acres. While it does not have outlet gates or associated structures, the dam's strategic location and design make it a critical asset for water resource management and climate resilience efforts in the region.

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.
