Landsat 5 captured an image of flooding occurring along the Iowa/Nebraska border on June 30, 2011. Flooding is still occurring on July 6, and Flood Warnings are still in effect from the National Weather Service.
The Landsat 5 image captured was an enlargement of the area just north of Omaha. The flood waters show up as very dark blue and, where the water is shallow, medium blue. In the image, the Interstate is cut off by flood waters, just south of Missouri Valley, Iowa, and about 20 miles north of Omaha.
