USGS Flood Inundation Mapper

The USGS Flood Inundation Mapping (FIM) Program helps communities protect lives and property by providing tools and information to help them understand their local flood risks and make cost-effective mitigation decisions.

The USGS Flood Inundation Mapping Program has two main functions:

  1. Partner with local communities to assist with the development and validation of flood inundation map libraries.
  2. Provide online access to flood inundation maps along with real-time streamflow data, flood forecasts, and potential loss estimates.
