Sitting at the confluence of the Iowa and Cedar Rivers in Louisa County, Columbus Junction has dealt with flooding issues including widespread events in 2008, 1993 and prior. The city was chosen in 2023 as one of four to join the Iowa Flood Resilient Communities Cohort, along with Muscatine, Dubuque and Manchester. These cities will work with the Iowa Flood Center (IFC) and American Flood Coalition (AFC) to mitigate future hazards.
