"Another Round of Lawsuits in Asian Carp Debate"

"Five Great Lakes states filed a lawsuit in federal court Monday to try to block Asian carp from entering Lake Michigan, the third attempt to seek the closing of Chicago-area shipping locks through the court system.

Spearheaded by Michigan Attorney General Mike Cox, the suit charges the U.S. Army Corps of Engineers and the Metropolitan Water Reclamation District of Greater Chicago with failing to stop movement of the feared invasive species toward the Great Lakes. The suit — brought by Michigan, Wisconsin, Ohio, Minnesota and Pennsylvania — asks the court to close shipping locks temporarily in the Calumet-Sag Channel and the Chicago River while other control methods can be put in place."
