The Fourmile Creek Roadfill Dam, also known as Ksnoname 728, is a state-owned structure located in Geary County, Kansas. Built in 1970 by USDA SCS, this earth dam stands at a height of 28.5 feet and has a hydraulic height of 40 feet. With a primary purpose classified as 'Other', the dam serves as a crucial water resource feature in the area, regulating the flow of Fourmile Creek-TR and providing a storage capacity of 134.07 acre-feet.

Despite its fair condition assessment, the Fourmile Creek Roadfill Dam poses a high hazard potential and is under the regulatory oversight of the Kansas Department of Agriculture. The dam, with a normal storage capacity of 7.13 acre-feet, covers a surface area of 2.08 acres and has a drainage area of 0.07 square miles. While it lacks outlet gates and a controlled spillway, the dam's uncontrolled spillway type raises concerns about its ability to handle peak discharges effectively.

Located in Junction City, Kansas, the Fourmile Creek Roadfill Dam is a significant component of the local water infrastructure, but its high hazard potential warrants close monitoring and potential risk management measures. Enthusiasts of water resources and climate in the area should take note of this dam's importance in regulating water flow and storage, as well as the need for ongoing inspection and maintenance to ensure its safety and integrity for the surrounding community.
