Chicago’s once-polluted river is finally showing signs of vibrant life and renewed public trust. Long associated with industrial waste and neglect, the Chicago River has been transformed through decades of cleanup, policy changes, and community action. Kayakers who once avoided the water now report spotting wildlife and enjoying clearer, healthier waterways.
Signs of a Healthier Ecosystem
Conservation teams from the Shedd Aquarium regularly kayak the river to document changes. They’ve observed an increasing number of fish species, turtles, and birds, along with social media-famous residents like “Chonkosaurus,” a massive snapping turtle that has become a symbol of recovery. These sightings underscore improvements in water quality and habitat restoration that have allowed wildlife to thrive in an urban setting.
Chicago Prepares for First Open-Water Swim in a Century
One of the clearest signs of renewed public confidence is the planned 2025 open-water swim in downtown Chicago—the first such event in nearly 100 years. Organized by the nonprofit A Long Swim, the event will take participants from the Dearborn Street Bridge to Lake Street. It also doubles as a fundraiser for swim education programs for underrepresented youth. As Axios Chicago reported, Mayor Brandon Johnson described the swim as proof of the city’s decades-long environmental work paying off.
What Sparked the Cleanup
The revival has been powered by several key forces:
- National policies like the Clean Water Act curbed industrial pollution.
- Local groups such as Friends of the Chicago River organized volunteer cleanups, riverbank restoration, and advocacy for stricter standards.
- Infrastructure upgrades, including improved sewage treatment, cut harmful runoff.
- Innovative projects like the “Wild Mile” floating wetlands added new habitat and green space in the river corridor.
These efforts combined to make the river safer, healthier, and more accessible.
A Model for Urban Waterway Renewal
Chicago’s transformation is inspiring other cities to reimagine their waterways. Groups like American Rivers highlight the Chicago River’s revival as a case study in how long-term planning and civic partnerships can turn degraded rivers into community assets. The return of fish, turtles, and beavers—along with the upcoming public swim—shows that the river is no longer simply a backdrop to the city but a vital part of its future.
Looking Forward
Challenges remain, especially during heavy rains when stormwater can overflow into the river. Yet the trajectory is clear: the Chicago River has shifted from being one of the nation’s most polluted waterways to a recovering urban ecosystem. Its story is a reminder that with persistence, investment, and imagination, even the most damaged rivers can be brought back to life.
