Managed by the local government and regulated by the Wisconsin Department of Natural Resources, Richards Mill has a significant hazard potential and is classified as having a very high risk level. Despite its fair condition assessment as of May 2020, the dam undergoes regular inspections every three years to ensure its safety and functionality. While the dam has not been modified since 1977, it remains a key feature in the region's water resource management and flood control efforts.
The dam's controlled spillway, with a maximum discharge of 218 cubic feet per second, plays a crucial role in managing water levels and mitigating potential risks. As part of the Chicago District, Richards Mill stands as a historical landmark from the 19th century, highlighting the intersection of engineering ingenuity and environmental stewardship in water infrastructure development. For water resource and climate enthusiasts, this site offers a unique opportunity to appreciate the intersection of human-made structures with natural landscapes in a picturesque setting.
