Frd No E-10, also known as Fall River Watershed Dam E-10, is a local government-owned dam located in Eureka, Greenwood County, Kansas. Constructed in 1966 by USDA NRCS, this buttress-type dam serves the primary purpose of flood risk reduction along the East Branch Fall River. With a height of 41 feet and a length of 1200 feet, it has a storage capacity of 675 acre-feet and a maximum discharge of 320 cubic feet per second.

Despite being rated as having low hazard potential and not currently assessed for condition, Frd No E-10 is regulated and inspected by the Kansas Department of Agriculture. The dam's inspection frequency is not specified, with the last inspection conducted in June 1979. While the dam does not have outlet gates, it is equipped with a spillway width of 40 feet to manage excess water flow during flooding events. The dam's location in a rural area underscores its importance in protecting the surrounding community from potential flood risks.

Water resource and climate enthusiasts interested in the management and infrastructure of dams will find Frd No E-10 a fascinating subject of study. With its vital role in flood risk reduction and its historical significance as a part of the East Branch Fall River watershed, this dam exemplifies the intersection of human engineering and environmental stewardship. As efforts to address climate change intensify, understanding the maintenance and regulation of structures like Frd No E-10 becomes increasingly crucial in safeguarding communities and ecosystems from the impacts of extreme weather events.
