Streamgage-linked Inundation Mapping Websites in Illinois—
Are Your Feet Wet Yet?

Inundation graphic The U.S. Geological Survey (USGS) streamgages have always been a valuable tool for local officials to help keep people and property safe during floods. The data available from these streamgages are now being taken a step further by mapping inundation surfaces associated with a range of gage heights corresponding to various out-of-bank flows and presenting them on the web. The USGS coordinates a national Flood Inundation Mapping Initiative group to further the science behind inundation mapping. Partners include the U.S. Army Corps of Engineers and the National Oceanic and Atmospheric Administration, National Weather Service (NWS) working together within the framework of the Integrated Water Resources Science and Services consortium to unify water science, observation, prediction and management. The USGS-Illinois Water Science Center has developed four streamgage-linked inundation websites for sites in Illinois. The websites are a tool for local officials flood response in their communities. The websites incorporate real-time USGS streamgage hydrographs, pre-determined inundation surfaces indexed to gage height, terrain data, and the NWS forecast hydrographs (where applicable) in a user-friendly Google map interface.

The USGS is partnering with the National Weather Service, United States Army Corps of Engineers and Federal Emergency Management Agency to develop flood inundation maps in locations across the country identified to be at the highest risk for flooding. These maps help identify where the potential threat of floodwaters is greatest, providing key information to Emergency Management officials to help them make quick decisions about when and how to evacuate residents threatened by rising floodwaters. State and local emergency managers will be able to use the interactive tool to better focus flood response and resource recovery and to swiftly assess evacuation routes. The public can also use the mapping application to better understand their personal flood risk and consequences.
