The Illinois Water-Quality Information -- 2002 Mapping Tool was developed in cooperation with the Illinois EPA to distribute water-quality data related to the Federal Clean Water Act. Users of the Mapping Tool can locate, create, and print maps of any size area within Illinois for use with Federal Clean Water Act issues. Map layers may be added by clicking the "visible" check box next to the layer name and pressing the Refresh Mapbutton. To locate an area of interest, select one of the following methods: use the Zoom tool to draw a rectangle (left click and drag) over the area of interest, or click on the Query tool and select an option that displays the area of interest. When finished, the map can be printed using the Print tool. First time users may want to visit the Introduction and Help page for more detailed instructions (also available through the Help tool).
