TRAVERSE CITY, MI –
Michigan Attorney General Mike Cox isn't giving up on closing Chicago shipping locks to keep Asian carp out of the Great Lakes.
A spokeswoman said Friday that Cox is still considering his options, including filing additional lawsuits.
The U.S. Supreme Court has twice refused Michigan's request to order closure of two locks on Chicago waterways.
And the U.S. Army Corps of Engineers on Thursday ruled out closure, except for brief periods to support measures such as dumping poisons where Asian carp are believed to be lurking.
Some fear the locks could provide a pathway for carp to Lake Michigan.
Scientists say if the carp become established in the Great Lakes, they could starve out popular sport fish such as salmon and walleye.
