Asian carp barrier erected along Des Plaines River

CHICAGO (AP) — A wire mesh fence is now up between the Des Plaines River and a shipping canal in an effort to keep the invasive Asian carp out of the river in the event of flooding.

The U.S. Army Corps of Engineers, environmental agencies and lawmakers marked the completion of the 13-mile-long barrier on Friday.

Asian carp can grow to 4 feet long and 100 pounds, and many fear they could starve out native fish if they get into the Great Lakes.
They’ve been making their way northward after escaping from Southern fish farms decades ago, and electric barriers in the canals are meant to stop them from going farther.

But the barrier between the Des Plaines River and the canal is meant to keep the fish from washing over into the river if the canal ever floods.
