The Mississippi River reached 47.87 feet (14.59 meters) in Memphis, Tennessee, on May 10, 2011, according to the Advanced Hydrological Prediction Service (AHPS) of the U.S. National Weather Service. It was the highest water level for Memphis since 1937, when the river reached 48.7 feet (14.8 meters). Fortunately in 2011, an effective flood-control system helped save most residents from harm, according to The Commercial Appeal. The Thematic Mapper on Landsat 5 captured the top image on May 10, 2011, and the bottom image (showing non-flooded conditions) on April 21, 2010. Both images are natural color and show the area as it would look to the human eye. In May 2011, muddy water has pushed over the Mississippi’s banks both east and west of the normal river channel. Flood waters span the distance between Memphis and West Memphis, and also fill a floodplain extending to an indu...
