Flood Maps for Iowans
Through a collaborative partnership between the Iowa Flood Center (IFC) and Iowa Department of Natural Resources (IDNR), interactive flood map products are available for all 99 counties in Iowa. The maps were produced with contributions from the U.S. Army Corps of Engineers and Iowa Natural Heritage Foundation and include every Iowa stream draining more than one square mile.
The maps are a critical resource to help citizens, emergency managers, and community leaders and decision-makers identify and communicate Iowa’s flood hazards and support informed floodplain management decisions.

Important Note
While some map products available may be adopted by FEMA and become regulatory, draft flood hazard maps are not regulatory maps. The products accessible through this site are provided for informational purposes. Iowans interested in map information for flood insurance purposes should visit the FEMA Map Service Center or contact local officials to view the current regulatory map for their jurisdiction.
