Bad Axe 33, also known as Sidie Hollow, is a local government-owned dam located in Vernon County, Wisconsin. Completed in 1965 by the USDA NRCS, this earth dam serves primarily for flood risk reduction along the TR South Fork Bad Axe river. With a height of 50 feet and a hydraulic height of 32 feet, the dam has a storage capacity of 1420 acre-feet and covers a surface area of 78 acres, making it an essential infrastructure for managing water resources in the region.

Despite its age, Bad Axe 33 has been well-maintained with regular inspections and a fair condition assessment as of November 2017. With a low hazard potential and moderate risk assessment rating, the dam continues to play a crucial role in mitigating flood risks and providing recreational opportunities for the local community. The dam's uncontrolled spillway and its location in a state-regulated area highlight the importance of its role in water resource management and climate change adaptation efforts in the region.

With Congressman Ron Kind representing the district, Bad Axe 33 stands as a testament to the collaborative efforts between local government, state agencies, and federal designers like the Natural Resources Conservation Service. As climate change continues to impact water resources, dams like Bad Axe 33 will be instrumental in ensuring the resilience of communities against flooding events and maintaining sustainable water management practices in Wisconsin.
