On May 19, 2011, the Mississippi River reached a historic crest at Vicksburg. According to the Advanced Hydrological Prediction Service (AHPS) of the U.S. National Weather Service, the river reached 57.10 feet (17.40 meters) that day. By early June, flooding had receded considerably around Vicksburg, but water remained high.
On June 14, the AHPS reported that the Mississippi River reached 44.88 feet (13.68 meters) at Vicksburg. At that point, the river was in minor flood stage, and its level was forecast to continue falling through June 19.
The Landsat series of satellites is used by emergency managers to acquire a range of imagery, from floods to fires. Landsat has recently provided both images of the flooding of the Mississippi River and the fires raging in Arizona.
The Landsat Program is a series of Earth-observing satellite missions jointly managed by NASA and the U.S. Geological Survey. Landsat satellites have been consistently gathering data about our planet since 1972. They continue to improve and expand this unparalleled record of Earth’s changing landscapes, for the benefit of all. The next Landsat satellite is scheduled to launch in December 2012.
