Until Friday, it was thought that the carp were in the Des Plaines River, which runs side-by-side with the canal that ultimately leads to Lake Michigan. To reach the Great Lakes, it would have taken a flood or a fish flopping three miles down Devon Ave. to the North Branch of the Chicago River. Now, it's known that the carp hopped the electric barrier on the canal. Life finds a way.

Scientists have found evidence that the Asian carp is now above the electric barrier on the Sanitary and Ship Canal and within a few miles of the Great Lakes. There's just one lock in their way on the Calumet River, which connects to the Mississippi River watershed through a web of other waterways.
