Hill is a privately owned earth dam located on Hattie Creek in Campbell, Wyoming. Built in 1944, this dam serves multiple purposes including fire protection, stock, and small fish pond management. It stands at a height of 16 feet with a hydraulic height of 11 feet and a structural height of 16 feet, stretching 450 feet in length. The dam has a storage capacity of 113 acre-feet, with a normal storage level of 54 acre-feet and a surface area of 10 acres.

Despite its low hazard potential, Hill is currently in poor condition as of the last inspection in October 2017. The dam has an uncontrolled spillway with a width of 300 feet and an outlet gate consisting of a single valve. The risk assessment for Hill is moderate, with a risk rating of 3. While the dam has not been modified in recent years, it is important for regulatory agencies to continue inspecting and monitoring Hill to ensure its safety and integrity in the face of potential climate-related challenges.
