Chicago River Day Annual Cleanup Effort

The 21st annual Chicago River Day will be held from 9 a.m. to noon, May 11. More than 4,000 volunteers will gather at 65-plus river-edge sites for a day of service along the banks of the Chicago River, from northern Lake County to Blue Island, in southern Cook County, to repair nature trails, remove harmful invasive plants and clear away garbage and debris from riverbanks.
