Lake of The Dells in Sauk, Wisconsin, is a privately-owned reservoir regulated by the Wisconsin Department of Natural Resources. Built in 1938, this earth dam stands at 16 feet high and has a hydraulic height of 12 feet, providing a storage capacity of 74 acre-feet. The dam's purpose and associated structures are not specified, but it serves as an essential feature in managing water resources in the area, particularly for flood control on the unnamed tributary to the Wisconsin River.

While the dam's hazard potential is classified as low, its condition assessment in 2020 was deemed fair, indicating the need for ongoing monitoring and maintenance. The last inspection in August 2011 revealed a 10-year inspection frequency, with emergency action plans potentially in place. The location's risk assessment, management measures, and inundation maps status are not specified, leaving room for further evaluation and potential improvements to ensure the safety and sustainability of Lake of The Dells for both water resource management and climate resilience purposes.

With a surface area of 14 acres and a proximity to the St. Paul District of the US Army Corps of Engineers, Lake of The Dells serves as a vital water resource in Wisconsin. As climate change impacts continue to affect water availability and quality, understanding and enhancing the infrastructure and management practices of such reservoirs are crucial for mitigating risks and ensuring the long-term resilience of water resources in the region.
