Nestled in Osseo, Wisconsin, the Frelk dam stands as a testament to USDA NRCS's commitment to flood risk reduction. Completed in 1970, this earth dam spans 520 feet and reaches a height of 17 feet, providing a storage capacity of 86 acre-feet. Serving multiple purposes including flood risk reduction, fish and wildlife habitat, and recreational opportunities, Frelk dam plays a crucial role in water resource management in the region.

With a low hazard potential and a moderate risk rating, Frelk dam is a vital piece of infrastructure in the Detroit District. Despite its age, the dam's condition assessment is not available, highlighting the need for regular inspections and maintenance. Supported by Natural Resources Conservation Service funding, the dam continues to serve the community by reducing flood risks and providing essential water storage for the area.

As climate change poses increasing challenges to water resource management, Frelk dam remains a critical asset in safeguarding the surrounding area from potential flooding events. With its uncontrolled spillway and uncontrolled outlet gates, the dam's design reflects a balance between flood protection and ecological considerations. As water resource and climate enthusiasts, Frelk dam serves as a reminder of the importance of sustainable water management practices in the face of changing environmental conditions.
