Summary
This earth dam, designed by USDA NRCS, was completed in 1969 for the primary purpose of flood risk reduction along the Spring Branch Caney River. With a height of 43 feet and a length of 1275 feet, Frd No 20 has a maximum storage capacity of 1350 acre-feet and a normal storage of 177 acre-feet, covering a surface area of 30.9 acres and draining a 4.7 square mile area.
Managed by the Kansas Department of Agriculture, Frd No 20 is regulated, inspected, and enforced by state authorities to ensure its safety and functionality. The dam's spillway type is uncontrolled with a width of 60 feet, and it has a low hazard potential with a moderate risk assessment rating of 3. While the condition assessment is currently not rated, the dam meets state permitting and inspection requirements, providing essential flood risk reduction benefits to the local community and the surrounding area.
Overall, Frd No 20 plays a crucial role in managing flood risks along the Spring Branch Caney River, safeguarding the community of Hewins and the surrounding region from potential inundation. With its strategic location and design, this earth dam stands as a testament to effective water resource management and climate resilience efforts, highlighting the importance of sustainable infrastructure for protecting our environment and communities from the impacts of extreme weather events.

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.
