WASHINGTON D.C. (AP) -- The United States Supreme Court won't order closure of shopping locks in the Chicago-area waterways to prevent Asian Carp from invading the Great Lakes.
The high court refused to hear an appeal from Michigan and other Great Lakes states who have been trying for immediate shutdown of the locks and a quicker timetable for other steps to halt the carp's northward march from the Mississippi River toward Lake Michigan.
The high court already rejected the request from Michigan, Minnesota, Ohio, Pennsylvania and Wisconsin twice.
The states have a pending lawsuit that calls for permanently severing a manmade link between the Mississippi and the Great Lakes drainage basins.
They wanted a court order to close the locks while their suit works through the courts.
