This USGS-sponsored site provides an explanation for the low oxygen conditions of the "dead zone" stemming from the Mississippi River and Gulf of Mexico watersheds. The factors that contribute to this eutrophication involve the landscape, agricultural and industrial practices, and changes in the Mississippi itself. The site features a color map of the drainage basins.
