A severe drought in 2012 devastated much of the United States, causing crop failure,
lower stream levels, and the drying and cracking of the ground. Obviously, a great deal
of water was needed to end this drought. At the end of August of that year, Hurricane
Isaac made landfall along the Gulf Coast of Louisiana and Mississippi and proceeded to
move up the Mississippi River and across central and northern Illinois by August 31
and September 1, precipitating large volumes of rain as it moved. How did the transit of
Hurricane Isaac affect the drought (Did it end the drought?)? How would groundwater
levels change? Explain your answers.
