Mississippi Valley Flooding

If you're looking for more information on this current weather tragedy than you might find on CNN or Fox, try some U.S. Government sites, like the Army Corps of Engineers Mississippi Valley Division. Here for example you can not only see news bulletins about when levee spillways will be opened, but also see maps, like this one of "Lower River Crest Locations/Dates," showing when and by how much the river crested at key points along the Mississippi. The USGS (US Geological Survey) is also a great source of water and flood information, for example the USGS Water Alert page.

You could find a lot of regional newspaper articles in Lexis, and good journal articles on river management and conservation in article databases like Environment Complete and ScienceDirect.
