Floods in the Ohio River Valley
This page contains archived content and is no longer being updated. At the time of publication, it represented the best available science. However, more recent observations and studies may have rendered some content obsolete.
Though water levels on the Ohio and Wabash Rivers appear to be falling, the rivers are still much fuller than they were on December 1, 2004. The floods were triggered by days of heavy rain over the Ohio River Valley in late December and early January. The rains ended by January 17, 2005, and the flood waters began to push downstream. In the left image, acquired on January 23, by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite, the Mississippi River and its tributaries bulge with water draining from the north. In both images, water is black and dark blue, clouds are light blue, and vegetation is bright green. Blue snow dusts the ground along the top of both images. MODIS also detected a few fires burning in Mississippi on January 23. These have been marked with red dots.
Flood water that filled the Ohio River in January 2005 reached the lower Mississippi in early February. MODIS observed high water levels on the river in Mississippi and Louisiana near Lake Pontchartrain.
