CHICAGO, Ill. (WRN) - Dead fish began surfacing Thursday on the canal off Lake Michigan where 6 miles of waters were poisoned. The Illinois DNR spread about 2,000 gallons of toxins on the Chicago Sanitary and Ship Canal – so the invasive Asian carp would not go into Lake Michigan through an electric barrier that’s being shut down for maintenance. As of 9 a.m., none of the fish that surfaced were Asian carp. But officials said everything was working as planned so far. And they expect to see the largest numbers of fish about 6 miles from the barrier on the side away from Lake Michigan. The DNR expects about 200,000 pounds of fish to turn up dead, including the Asian carp and several other species. A week ago, experts said DNA from the carp was found beyond the barrier, indicating that the 4 foot eater of native fish had broken into the Great Lakes. But officials still don’t believe there are enough for mass reproductions – and Michigan officials and environmental groups are seeking legal action to close navigational docks close to Lake Michigan to keep the carp out.
