Major Watersheds of Illinois
A watershed is all of the landscape that drains into a particular
lake or river. The Illinois State Water Survey (ISWS) divided Illinois into
33 major watershed basins. Hydrologic unit codes (HUCs) were developed
by the US Geological Survey (USGS) to identify watershed boundaries.
USGS has mapped Illinois’ watersheds at a 10-digit HUC. These smaller
watersheds are used by Illinois EPA to group and prioritize impaired waters
of the state and for use in TMDL development. These 10-digit HUCs are
delineated in each of the 33 watershed basin maps.
