Standing at 33 feet high and spanning 450 feet in length, this earth dam serves primarily for recreational purposes with a storage capacity of 108 acre-feet. Situated on the TR-Difficult Run river, the dam's hazard potential is classified as low, and its condition assessment is deemed satisfactory as of the last inspection in July 2020.
Despite its low hazard potential, Fox Lake Dam plays a crucial role in providing recreational opportunities for the local community while also serving as a water resource management structure. With a surface area of 7 acres and a drainage area of 0.17 square miles, the dam contributes to the conservation and utilization of water resources in the region. Furthermore, its satisfactory condition and regular inspections ensure its continued functionality and safety for both recreational and water management purposes.
In the event of an emergency, it is essential for the owners of Fox Lake Dam to have an Emergency Action Plan (EAP) in place, although the last revision of the plan dates back to April 2013. With proper risk assessment and management measures, the dam can continue to serve its intended purposes while mitigating potential hazards. As climate change continues to impact water resources, structures like Fox Lake Dam play a vital role in ensuring water security and recreational opportunities for the community.
