|Water Withdrawals and Population in Various Regions of Illinois||Back|
The quantity of water withdrawn for various public and domestic uses varies
dramatically from region to region within Illinois. The following graphics illustrate the
variation in water withdrawals and population within major regional planning areas
defined by major watersheds within Illinois. These regions were identified and used by
the U.S .Army Corps of Engineers in the late 1960s as part of comprehensive surveys of
the upper Mississippi River and the Ohio River basins. At that time comprehensive
information about water withdrawals was compiled for these regions.

charts for the Big Muddy and Saline,
planning regions show past, present, and future
populations, and past and reported water withdrawals. Note: When these graphics were
compiled, the 2000 census was not complete, and 2000 and 2020 populations shown are
projections. Water withdrawal data shown includes withdrawals for public, commercial,
industrial, and estimated self-supplied domestic water use, but not for power generation.
The graphic that includes all six regions plots water withdrawals and population data at
the same scale for all regions, thus illustrating the predominance of population and water
withdrawals in Northeastern Illinois.
