Regional leaders are scheduled to meet in Chicago next month to discuss a plan devised by the U.S. Army Corps of Engineers for preventing invasive Asian carp from reaching Lake Michigan.

The head of the Army Corps of Engineers has sent Congress a $778 million plan to fortify an Illinois waterway with noisemakers, electric cables and other devices in the hope that they will prevent Asian carp from reaching the Great Lakes.

Officials say genetic material from Asian carp has been detected near Lake Michigan, but a follow-up search turned up none of the invasive fish.

If you can’t beat ‘em, eat ‘em. That’s the apparent strategy behind a new state grant program that will provide funding to companies that harvest and sell Asian carp.

Michigan offered to give Illinois $8 million to keep Asian carp out of the Great Lakes. But Illinois Gov. Bruce Rauner has a different idea about how to spend the money.

Additional engineering and design work has more than doubled the cost of a long-awaited plan to prevent invasive Asian carp from reaching the Great Lakes, according to federal officials.

Each year, self-proclaimed “rednecks” try to rid the Illinois River of Asian carp – one flying fish at a time. We visit the small town of Bath for a look.

A new team led by biologist Andrew Casper will expand Shedd Aquarium’s research of animals that live in local waterways—and how to protect them.

Nearly a dozen U.S. senators, including Dick Durbin of Illinois, are speaking out about the latest delay over a plan to keep invasive Asian carp out of the Great Lakes.

The U.S. Army Corp of Engineers says the best place to stop Asian carp from getting into the Great Lakes is the Brandon Road Lock and Dam in Joliet. But the state says the plan is too expensive for Illinois taxpayers and the shipping industry.

A plan to fortify a barrier against Asian carp was set to be released in February but has been stalled by the Trump administration.

An 8-pound Asian carp was discovered last week beyond an electric barrier designed to prevent the invasive fish from reaching Lake Michigan.

With nearly $300 million in federal funding on the chopping block, leaders from across the Great Lakes region will convene next month in Chicago to address lead poisoning, oil pipelines and other threats to the area’s waters.

Wildlife agencies and fishermen in Illinois are using a Chinese technique to catch Asian carp, an invasive fish species threatening the Great Lakes ecosystem.
