Deal reached on project to protect lakes from invasive fish

The plan calls for installing fish-repelling mechanisms at the Brandon Road Lock and Dam near Joliet, Illinois.

The area is a choke point between the carp-infested Illinois River and Lake Michigan.

Both states agreed to pay some of the design and engineering costs for the $858 million project.

Scientists say if Asian carp reach the Great Lakes, they could out-compete native fish for food and habitat.
