In another attempt to locate the potential threat of Asian carp in the Great Lakes, officials began dumping approximately 2,000 gallons of the organic fish poison Rotenone yesterday into a two-mile stretch of the Calumet-Sag Channel, about seven miles west of Lake Michigan. The aim is to kill and count any invasive carp potentially lurking in the waterway as proof that these fish are spreading into Lake Michigan.
