Mississippi River Flooding
Landsat satellite data recorded major flooding in the Memphis, Tennessee, area on May 10, 2011. The Mississippi River crested at 47.87 feet on May 10. That crest represents the second highest rise in recent history; the highest recorded was 48.7 feet in 1937.
The Landsat data are being used to monitor the flood rate and the effects of the flooding in the region. Five surrounding counties have been declared disaster areas and the costs of the flooding will approach $1 billion.
In the image, dark blue tones are water, light green areas are cleared fields, and the light tones are clouds.
