Fall River Dam, also known as Fall River Lake, is a Federal-owned gravity dam located in Fall River, Greenwood County, Kansas. Completed in 1948, the dam stands at a height of 94 feet and has a capacity of 256,400 acre-feet, serving primarily for flood risk reduction, water supply, and other purposes. With a controlled spillway width of 400 feet, the dam has a high hazard potential and is classified as having a very high risk, primarily due to the potential for overtopping during rare flood events.

To manage and mitigate the risks associated with Fall River Dam, the US Army Corps of Engineers (USACE) has implemented various measures, including routine inspections, emergency action plans, equipment stockpiling, and communication strategies. USACE also conducts regular maintenance activities and detailed inspections to ensure the dam's integrity, as well as employs instrumentation and monitoring systems to monitor changing conditions. Despite the risk of flooding in nearby communities such as Fall River, Fredonia, Neodesha, and Coffeyville, USACE's efforts aim to minimize the potential impacts on lives and the economy in the event of a dam failure or large flood event.
