Illinois is rebranding Asian carp as “copi” in a bid to get people to eat the invasive fish into submission. Fishermen are catching thousands of pounds a day and barely making a dent in the number of carp in waterways like the Illinois River, where it's estimated 20 million to 50 million could be harvested annually.

Legislation signed Thursday by Gov. J.B. Pritzker now mandates the placement of rescue equipment along Lake Michigan access points, including piers.

A stalled movement to give the invasive Asian carp a more palatable name has regained momentum, and the big reveal is now set for June 22.

Field studies over the past few weeks — a collective effort known as the “Winter Grab” — were intended to boost knowledge of what happens in the five lakes when they’re covered partially or completely with ice.

As enchanting as Lake Michigan's ice may appear, it’s unmistakably dangerous, as evidenced this week by the presumed drowning of an Indianapolis man who fell into the water off shelf ice at Indiana Dunes National Park on Monday.

The infusion from the bipartisan measure enacted in November, combined with annual funding through an ongoing recovery program, will enable agencies by 2030 to finish work on 22 sites designated a quarter-century ago as among the region's most degraded.

Lake scientists have long considered winter a season when aquatic activity slows. But researchers now think more is going on in the bitter depths than previously believed — including activity influenced by climate change.

Great Lakes Governors Say, ‘Not Us’

Great Lakes governors are asking the federal government to fund costs of the Brandon Road Lock and Dam project on the Des Plaines River, designed to block the incursion of invasive carp into the lakes.

Each year, 22 million pounds of plastic finds its way into the Great Lakes – the source of potable water for more than 30 million Americans. We take a look at what can be done to limit plastic pollution.

Coastal repairs and climate change mitigation are a huge concern for cities around the Great Lakes region. The group behind a new survey calls on the American and Canadian governments to fund local efforts to address these issues.

At the end of June, Illinoisans will no longer hear the words “Asian carp.” After several years and hundreds upon hundreds of millions spent trying to keep them from the Great Lakes, how can that possibly be? We explain.

The 240-pound, 100-year-old, nearly 7-foot-long sturgeon is making headlines. But fish that size used to be common in the Great Lakes and maybe, thanks to restoration efforts, they will be again.

When it comes to what scientists know about the effects of climate change on the Great Lakes, research to date has only scratched the surface. A new study shows that Lake Michigan is warming — even its greatest depths. “This is a large effect, not just something superficial,” scientists say.
