A16 Pond Dam, also known as Pond 60, is a Federal-owned structure in Williamson, Illinois, managed by the Fish and Wildlife Service.
Built in 1970, this Earth dam stands at 13 feet high and spans 1260 feet in length, providing a storage capacity of 407 acre-feet for its primary purpose as a Fish and Wildlife Pond. The dam is regulated by the Illinois Department of Natural Resources and undergoes regular inspections to ensure its safety and functionality.
With a low hazard potential and a moderate risk assessment rating, A16 Pond Dam poses minimal danger to its surrounding area. Despite its unsatisfactory condition assessment in 2011, the dam continues to serve its purpose effectively, with a normal storage capacity of 110 acre-feet and a maximum discharge rate of 4430 cubic feet per second. The dam features an uncontrolled spillway with a width of 250 feet, ensuring proper water management during high flow events.
Located in an unnamed stream, A16 Pond Dam plays a crucial role in supporting the local ecosystem and providing habitat for fish and wildlife. With its association with the Fish and Wildlife Service, the dam not only serves as a water resource management structure but also contributes to conservation efforts in the region. Its historical significance and ongoing maintenance highlight the importance of sustainable water infrastructure for climate resilience and ecosystem health.
