“Of the lakes in the study, Grand Lake and Buckeye Lake were said to be the “dirtiest.” The average microcystin concentration levels for both lakes were well above the no-drinking threshold set by the WHO, with Grand Lake’s average microcystin level exceeding the WHO’s no-contact threshold.”

Asian invader: An eight-pound silver carp was caught earlier this summer in the Chicago Area Waterway System, about nine miles from Lake Michigan. That's about 30 miles past electric barriers designed to keep Asian carp out of the system and the Great Lakes.
An autopsy conducted by Southern Illinois University showed that the male silver carp spent a quarter of its life in the Middle Mississippi/Illinois River watershed, a quarter of its life in the Des Plaines River watershed and found its way above the electric barriers within the last few weeks or months before it was caught in a pool below the T.J. O’Brien Lock and Dam.
