Frd No 8-23, also known as Twin Caney Watershed Dam 8 23, is a vital water resource structure located in Sedan, Chautauqua County, Kansas. Owned by the local government and regulated by the Kansas Department of Agriculture, this earth dam stands at a height of 55 feet and was completed in 1968 to primarily reduce flood risk in the area. With a storage capacity of 3,667.15 acre-feet and a drainage area of 9.99 square miles, this dam plays a crucial role in managing water flow in the Pool Creek watershed.

Managed by the USDA NRCS and designed by the Natural Resources Conservation Service, Frd No 8-23 has a spillway width of 270 feet and a maximum discharge capacity of 15,700 cubic feet per second. Despite being classified as having a low hazard potential, the dam is rated as having moderate risk due to its age and condition. The structure has not been rated for its current condition, and there are no emergency action plans or inundation maps prepared for this dam, highlighting the need for further assessment and risk management measures to ensure its long-term safety and functionality. Water resource and climate enthusiasts will find Frd No 8-23 to be an intriguing example of flood risk reduction infrastructure in a scenic Kansas landscape.
