Drought in Illinois

Drought is a complex physical and social phenomenon of widespread significance, and despite all the problems droughts have caused, drought has been difficult to define (see What is Drought?). In fact, the most straightforward way to identify a drought is by looking at the impacts such as crop losses, low water levels in lakes and streams, and water shortages, rather than specific definitions of shortfalls in precipitation.
