What is a Watershed?
A Watershed = The land that water flows over and through on its way to a stream, river or lake.

• Wherever you live, you are a part of a watershed.
• A large watershed, such as the Mississippi River, has many subwatersheds where each subwatershed is the land that drains to a specific waterbody.
• The Illinois River watershed is a subwatershed of the Mississippi watershed.
• The Fox River watershed is a subwatershed of the Illinois River watershed.

Map of Entire Fox River Watershed, including headwaters in Wisconsin
FREP focuses on the Fox River Watershed in Illinois. However, the headwaters of our Fox River actually start in Wisconsin.

The large Fox River watershed in Illinois includes many subwatersheds.
Citizens in a number of these have organized associations to help protect and improve their area. Information and website links are provided below for any existing groups, as well as information if a management plan has been developed.
Listed below are key subwatersheds of the Fox River in Illinois
We will continue to add information and subwatersheds to make this page as comprehensive as possible
For additional information on a particular subwatershed, please visit the links provided
If you have information about a subwatershed group to include here - please Email: info@foxriverecosystem.org
