Dam A-41, located in Williamson County, Illinois, is a Federal-owned structure managed by the Fish and Wildlife Service.
Built in 1965, this Earth-type dam stands at a height of 24 feet and spans 600 feet in length, serving primarily as a Fish and Wildlife Pond. With a capacity to hold 620 acre-feet of water and covering a surface area of 43 acres, Dam A-41 plays a crucial role in maintaining the local ecosystem and providing habitat for various species.
Despite its low hazard potential, Dam A-41 is currently assessed to be in poor condition as of the last inspection in 2011. The dam has undergone structural modifications in 2006 to ensure its continued safety and functionality. While it meets state regulatory standards for inspection, permitting, and enforcement, there is a need for further assessment and maintenance to improve its overall condition and reduce potential risks.
In the realm of water resource and climate conservation, Dam A-41 serves as a vital component in the management of water resources and preservation of wildlife habitats in Illinois. As efforts continue to assess and enhance the dam's condition, it remains an important structure for both environmental protection and recreational purposes in the region.
