Site 120, also known as Branson Sp Dam, is a vital flood risk reduction structure located in Douglass, Kansas. Built in 1973 by the USDA NRCS, this earth dam stands at a height of 33 feet and has a storage capacity of 800 acre-feet. The dam's primary purpose is to protect the area from the potential devastation of flooding, particularly along the Four Mile Creek-TR.

With a low hazard potential and a moderate risk assessment rating, Site 120 is a crucial piece of infrastructure in Butler County, Kansas. Managed by the local government and regulated by the Kansas Department of Agriculture, the dam is regularly inspected and maintained to ensure its effectiveness in flood risk reduction. Despite its uncontrolled spillway type, Site 120 has a spillway width of 50 feet, ready to handle a maximum discharge of 100 cfs in times of high water flow. For water resource and climate enthusiasts, this dam serves as a fascinating example of how engineering and nature can work together to protect communities from the forces of nature.
