Any development on the Chicago River should address concerns about climate resilience, biodiversity, sustainability and pollution, advocates say. "It would be an enormous mistake to not take that seriously," said Margaret Frisbie, of Friends of the Chicago River.

Freshwater mussels can be a river system’s best friend, but they’re missing from long stretches of the Chicago River. Here’s a look at one effort to reintroduce them.

The giant snapping turtle spotted in the Chicago River became a viral sensation this week. But the river is home to lots of wildlife, thanks to ongoing efforts to clean up the waterway.

Every time you flush, the waste disappears in a swirly whirl, never to be seen again. It’s magic! Actually, it’s science and engineering. WTTW News Explains.

Researchers from Shedd Aquarium and Chicago-based Urban Rivers teamed with counterparts in Boston and Baltimore and confirmed that floating wetlands can improve water quality and provide vital habitat.

“Any riverfront improvement opportunity should be part of a master plan that recognizes the Chicago River system as the wondrous natural resource it is rather than the uncared for alleyway it used to be,” said Friends of the Chicago River.

The area around Bubbly Creek was once a wetland, until the channel became choked first with sewage and then animal waste from the Union Stockyards. Now the wetlands, with a twist, are making a comeback.

In its 30-year history, Friends of the Chicago River’s annual cleanup has evolved from a focus on litter to invasive species. An invasive crayfish pulled from the river over the weekend highlights the work to be done.

Even with officials from several government entities keeping watch, someone dumped dye into the North Branch of the Chicago River, turning it bright St. Patrick's Day green over the weekend.

Dyeing the Chicago River green on St. Patrick’s Day has been a tradition since the 1960s. But in 2020 and 2021, rogues extended the practice to a section of the North Branch, a bridge too far for environmentalists.

Back in the 1980s, the number of fish species found in the Chicago River could be counted on a single hand. Today, that number is up to 60 species, an increase in diversity that can be directly attributed to a decrease in wastewater pollutants, according to a new study from the Shedd Aquarium.
