Steve,
Most of what was flooded in many places was originally a flood plain in the first place. They finally made those dirt dams illegal as they bust and so do those levees. After so long, that water is going to soak it through. Then a big surge and it breaks. I watched a show on TV yesterday that said we have over 1,000 dams in the United States that are now considered dangerous and could break at any time if they have a big rain or even a small earthquake. Then one of their engineers made a stupid statement. He said that they don't have to worry about seismic activity in that area. There is a chance of a quake anywhere in the world and to make a statement like that is asinine. One of the largest earthquakes they have ever found traces of happened back in the middle of the country around the St. Louis area and in that region. It changed the Mississippi Rivers flow.
