Congress authorized a plan from the Army Corps of Engineers to restore the Chicago River’s South Fork, a 1.25-mile stretch more familiarly known as Bubbly Creek. Now actual dollars need to follow.

Walking along Lake Michigan or the Chicago River, it’s difficult to imagine an underwater world teeming with life. But it’s there, promises Karen Murchie, a research biologist at the Shedd Aquarium, and we have to protect it.

An upcoming virtual tour will offer insights into the Metropolitan Water Reclamation District’s inner workings and will revisit the reversal of the Chicago River.

Rafts loaded with plants floated down the Chicago River last week, a strange sight that in decades past might have been the result of some sort of bizarre garbage spill but these days is a sure sign of the waterway’s ongoing “re-wilding.”

This spring, Chicago saw record rainfall for the third May in a row – and with it, the return of flooded streets, parks and basements. A new analysis finds many more Chicago properties are at risk of flooding than previously thought.

Early Monday morning, the North Branch Chicago River gauge at Pulaski Road showed the waterway at 17.87 feet, inches away from the river's "minor" flood level at 18 feet, according to National Weather Service data.

The organization had to cancel its Chicago River Day cleanup due to the coronavirus. Instead of bringing thousands of volunteers together for a one-day event, the new Summer Challenge encourages people to pick up litter in their neighborhoods.

The east bank of the North Shore Channel has been stripped of foliage between Foster and Bryn Mawr avenues, to be replaced with native species. Neighbors say the project has laid bare “eyesores” on the opposite bank.

On Chicago’s Northwest Side, a gently sloping riverbed occupies the former site of a small but historically important dam. We visit a popular fishing spot – for humans and birds alike – at River Park.

What lies below the surface of the Chicago River today is not what it was a century ago, but pollution is still a problem. A Chicago nonprofit aims to offer real-time water quality data to the public later this year.
