The Milwaukee Journal Sentinel newspaper agrees with me that the manmade connection between the Mississippi River basin and the Great Lakes should be closed.
In an editorial headlined “Let science prevail in Fight over Chicago canal,” it says the following:
“The Army Corps of Engineers is looking more like a guy who can smell smoke but won't admit there's a fire because he can't see flames. The smoke is rising from the Chicago Sanitary and Ship Canal in the form of DNA evidence that the Asian carp is close to entering Lake Michigan, if it already hasn't done so.
“But with only two actual dead carp found - one on either side of an electrical barrier in the canal designed to stop the fish - Army Corps Maj. Gen. John Peabody isn't ready to do the obvious: close the canal that destroyed the natural barrier between the Great Lakes and Mississippi River basins when it was built in the 19th century.”
We must close that connection not only to keep Asian Carp out of the Great Lakes. We must close it because the canal is an open door for other invasions. For example, zebra and quagga mussels used that route --- as well as hitchhiking --- to spread into the Mississippi River and, from there, all across the country.
