The Google Crisis Response team has assembled a collection of Mississippi River floods data including satellite imagery for impacted cities along the river from GeoEye, flood extent and crest data forecasts from the US Army Corps of Engineers (kml) and NOAA’s National Weather Service (kml), and shelter locations from the American Red Cross (kml).
Emerging as one of the worst flooding events along the U.S. waterway in the past century, the Mississippi River floods of April and May 2011 have caused widespread destruction along the 2,300 mile river system.

This collection of data is available on Google Maps by searching for “Mississippi flooding.” These data can also be accessed within Google Earth by turning on the ‘Places’ layer and flying to the Mississippi river south of Memphis, TN, or by downloading this kml to open in Google Earth.
