Aux Sable Creek
Aux Sable Creek

The Aux Sable Creek watershed drains the majority of southern Kendall and portions of Grundy & Will Counties.  Aux Sable Creek is one of the highest quality streams in northeastern Illinois.

Significant tributaries include the East, Middle and West branches of the Aux Sable as well as Valley Run, Walley Run, Collins Run, Lisbon Creek, and Saratoga Creek. It is a sub-watershed of the Illinois River, and part of the Prairie Parklands Ecosystem Partnership (PPP). It is home to the Baker Woods Forest Preserve in Kendall County and numerous beautiful stretches along the wooded creek.

It has been comprised of primarily of farmland with some industrial complexes in the southern portion of the watershed. It has recently experienced rapid suburban development which can greatly impact the quality and stability of the creek. Developments in Joliet, Minooka, Plainfield, and Yorkville have already been built in the watershed. 

In 1997, a committee comprised of local citizens and community leaders formed to create a watershed plan working with the Natural Resources Conservation Service (NRCS) and Kendall County Soil & Water Conservation District (SWCD). It included technical information about the Aux Sable Creek as well as what representatives from various perspectives might do to protect and preserve the 185 square mile watershed.

In 2007, The Conservation Foundation was asked to help facilitate an update to the previous plan to meet new criteria for Watershed Based Action Plans developed by the U.S. Environmental Protection Agency. The Conservation Foundation worked with the Aux Sable Creek Watershed Coalition to obtain a grant to update the plan. Foundation staff also facilitated the update, convening the various stakeholders in the watersheds (landowners, local government representatives, conservation organizations, etc.) to provide input. The plan was completed in June of 2009 and can be found on the Aux Sable Creek Coalition Website at
