9, also known as Rock Mill Lake, is a vital Earth dam located in Fairfield, Ohio, designed by USDA NRCS in 1959 for flood risk reduction along the Hocking River. This structure is state-regulated and maintained by the Department of Natural Resources, with a high hazard potential due to its 76 feet height and 1010 feet length. The dam has a normal storage capacity of 158 acre-feet, serving a drainage area of 7.14 square miles.
With a fair condition assessment as of the last inspection in May 2017, Hunters Run Structure No. 9 poses a moderate risk level (3) and undergoes inspections every 5 years. Despite the uncontrolled spillway type and outlet gates, the dam has a maximum discharge capacity of 18,127 cubic feet per second, ensuring effective flood risk reduction measures. The structure's location in Hooker, Ohio, highlights its importance in protecting the surrounding area from potential inundation events, showcasing the collaboration between local government and the Natural Resources Conservation Service in safeguarding water resources and mitigating climate-related risks.
