Carp threaten Chicago shipping: Illinois politicians unite over lawsuit
 

They know the Court already has ruled the Canal illegal so Corporations
and their Politicians are going to try to buy Congress and the EPA not

Chicago is using the Mississippi as a sewer and to hell with the Great
Lakes.
Make them move the water intake below the sewer pipe and force them to
clean up the sewage which is not adequately treated.imho
