In 2008, Illinois received an unprecedented amount of rainfall, which flooded thousands of acres of agricultural lands. Historically, much of this land was floodplains that held and drained water. But in the past century, over half of the floodplains in Illinois have been altered by levees, lock and dams, and stream channelization. Water that enters these lands not only takes longer to drain, but also causes millions of dollars in crop damage.
