The Mississippi River Valley in western Illinois is the land area drained by the main stem of the Mississippi River, excluding its major Illinois tributaries: the Rock, Illinois, Kaskaskia, Big Muddy, and Cache. Agriculture is the primary use of land within the watershed, although many grasslands and forests are present as well.
