Roiger Detention, located in Springfield, Minnesota, is a privately owned earth dam designed by the USDA NRCS with a primary purpose of flood risk reduction. Completed in 1986, this structure stands at a height of 32 feet and stretches 750 feet in length, with a storage capacity of 141 acre-feet. Situated on Mound Creek-TR, Roiger Detention serves to mitigate potential flooding events in the area, providing essential protection to the surrounding community in Brown County.

Managed by the Minnesota Department of Natural Resources, Roiger Detention is subject to state regulations, permitting, inspections, and enforcement to ensure its structural integrity and functionality. Despite being classified as low hazard potential with a satisfactory condition assessment, the dam is equipped with uncontrolled spillways and outlet gates. With a moderate risk assessment rating, ongoing risk management measures are essential to maintain the effective operation of this vital flood control structure.

With Congressman Jim Hagedorn representing the area in the US House of Representatives, Roiger Detention plays a crucial role in safeguarding the local environment and population from the impacts of extreme weather events. As a key component of the flood risk reduction infrastructure in the region, this earth dam stands as a testament to the collaborative efforts between private owners, government agencies, and designers to protect water resources and mitigate the effects of climate change in Minnesota.
