Frd No F-3, also known as Fall River Watershed Dam F-3, is a vital structure located in EUREKA, Greenwood County, Kansas. Owned by the local government and regulated by the Kansas Department of Agriculture, this earth dam stands at a height of 42 feet and was completed in 1966. Its primary purpose is flood risk reduction, serving the West Branch Fall River-TR with a storage capacity of 2356.08 acre-feet.

Managed by the Natural Resources Conservation Service, Frd No F-3 has a low hazard potential and a moderate risk assessment rating of 3. With a normal storage capacity of 143 acre-feet and a maximum discharge of 421 cubic feet per second, this dam plays a crucial role in protecting the surrounding area from potential flooding events. Although its condition assessment is currently not rated, regular inspections and enforcement ensure its structural integrity and operational effectiveness.

Despite its uncontrolled spillway type and lack of outlet gates, Frd No F-3 continues to fulfill its purpose of flood risk reduction in the region. With a surface area of 30.25 acres and a drainage area of 5.33 square miles, this key infrastructure is a testament to the collaborative efforts between local government agencies and the USDA NRCS in safeguarding water resources and mitigating climate-related risks in Kansas.
