Magruder is a privately owned dam located in Sauk, Wisconsin, primarily used for recreation and flood risk reduction along a tributary to Plum Creek. Built in 1970 by the USDA NRCS, this earth dam stands at 29 feet high and spans 435 feet in length, with a storage capacity of 50 acre-feet. Despite its low hazard potential, the dam is currently in poor condition according to a 2018 assessment, highlighting the need for maintenance and updates to ensure its safety and longevity.

The dam is regulated by the Wisconsin Department of Natural Resources and undergoes regular inspections, with the last one conducted in 2009. While the risk assessment for Magruder is moderate, with a rating of 3, there are no specific risk management measures in place as of the latest data update in May 2021. As water resource and climate enthusiasts, there is a clear opportunity to advocate for improved maintenance and emergency preparedness for this vital infrastructure to protect both the environment and the surrounding community from potential risks and hazards.
