By the time the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite passed over Des Moines, Iowa, on June 29, 2008, and captured this image, the floods that had struck the city in mid-June when an aging levee failed were no longer apparent in the city itself. However, downstream (southeast) of the city, the flooding remained dramatic.
In June 2008, intense spring rains pushed the Iowa River over its banks in Iowa City. Though the flood had started to recede when the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite captured the top image on June 22, the river was still swollen.
A wall of water washed over the small riverside city of Gulfport, Illinois, when at least two levees on the flooded Mississippi River burst on June 18, 2008, reported CNN. Only treetops and a few roofs were visible above the surface of the blue-green water two days later on June 20, when the commercial satellite Ikonos captured this detailed photo-like image.
Nearly every river and creek shown in the top false-color image of eastern Iowa was flooded on June 13, 2008. Compared to June 1, the river systems look as if they have been outlined in black or dark blue, the color of water in this type of image.
Heavy rains in early June 2008 soaked the U.S. Midwest, leaving swollen rivers in their wake. By June 8, 2008, the National Weather Service had issued flood warnings for numerous counties throughout Indiana and Illinois. The lower Wabash, White, and East Fork White watersheds had all been affected by the deluge, according to National Weather Service bulletins, and streamflow gauges on parts of the White and East Fork White River recorded 100-year-flood levels, according to preliminary reports from the U.S. Geological Survey.
