Post Group Detention, located in Murray, Minnesota, serves as a vital structure designed by USDA NRCS to address flood risk reduction along the Chanarambie River. Completed in 1974, this private-owned Earth dam stands at a height of 34 feet, with a capacity of 177 acre-feet for storage. With a low hazard potential and fair condition assessment, Post Group Detention is regulated by the Minnesota Department of Natural Resources and undergoes regular inspections to ensure its functionality.

Despite its modest size, Post Group Detention plays a crucial role in managing water resources in the region, offering flood risk reduction benefits to the surrounding community. The dam's uncontrolled spillway and outlet gates, in combination with its buttress core type, contribute to its operational efficiency. While the dam's primary purpose is flood risk reduction, it also serves as a testament to effective collaboration between private ownership and state regulatory agencies to safeguard against potential water-related emergencies.

With its moderate risk assessment and a history of maintained functionality, Post Group Detention exemplifies the importance of proactive water resource management in mitigating the impacts of climate change. As climate enthusiasts and water resource advocates continue to monitor and support such structures, Post Group Detention stands as a testament to the intersection of infrastructure, regulation, and environmental stewardship in safeguarding local communities against the threats of flooding and water scarcity.
