Chicago River Day 2025 - Caldwell Woods

Site Captains: Jim O'Connor, Mark McHugh

Meeting Spot: Caldwell Woods Picnic Grove 2, first parking lot east of Milwaukee

The Chicago-Calumet River system is healthier now than it’s been in 150 years, but litter continues to be detrimental, hurting people and wildlife and causing negative community, economic, and public health impacts. You can make a difference by volunteering with Friends of the Chicago River on Chicago River Day - our fun, free, family-friendly annual cleanup Saturday, May 10, 2025 from 9 a.m. – 12 p.m.

Chicago River Day is an outdoor event located at over 75 sites including city parks, forest preserves, school yards, and businesses along the banks of the Chicago-Calumet River system and its tributaries. At most sites, volunteers pick up trash, though volunteers may help with additional stewardship activities at some locations like removing invasive plants and trail maintenance, depending on the needs of the site.

Registration for Chicago River Day is open until a site reaches capacity. Children eight and up are eligible to volunteer with a guardian. Younger family members are welcome to observe provided they are supervised by an adult. Advance registration requested for all participants ages eight and up. Volunteers who register before Friday, May 2, 2025 receive a Chicago River Day T-shirt highlighting this year’s featured creature, the Spotted Gar.
