"The Supreme Court on Monday rejected another request by the state of Michigan for an order to close two Chicago-area waterway locks to keep Asian carp from invading the Great Lakes.

The high court turned down Michigan's initial request on January 19 but the state filed a new motion after the discovery of carp DNA in water samples taken from the Calumet Harbor on Lake Michigan, at the mouth of the Calumet River."
