The government created the flood—written in 1999 about a different (but similar) flood.
“Ignoring science and experience, military engineers consistently marched to the tune of the “levees-only theory,” which in practice requires a huge capital and maintenance expense to build and maintain these ever-higher earth- and stoneworks to hold back the floodwater. A levees-only approach caused sediment to accumulate on the river bottom forcing engineers to regularly raise the level of the levees to hold the same amount of water. The mighty Mississippi River had literally been lifted above ground level in many places. It is obvious that this strategy created the potential for increasingly severe flood damage.”
