Michigan's attorney general says he will sue to try to force the closure of Chicago-area locks to protect the Great Lakes from the invasive Asian carp.
Attorney General Mike Cox said in a statement Sunday that the federal lawsuit will be filed soon but his office did not provide an exact time frame.
The suit would aim to close locks in the Chicago Sanitary and Ship Canal, where officials found one carp Thursday.
Authorities are trying to ensure the carp don't reach Lake Michigan, where they could starve out smaller, less aggressive competitors and endanger the Great Lakes fishing industries.
But closing the locks could also disrupt the movement of millions of tons of iron ore, coal and other goods.
Part of the canal was poisoned last week in an effort to kill the carp.
