Beaches along Lake Michigan are closed when E. coli bacteria gets too high. But a nasty critter found on the bottom of the lake might help keep the beaches open.

Lake Michigan’s E. coli and swimming advisories are down from previous years. A recent study says that’s both good and bad.

The study looks at Lake Michigan’s beaches from 2000 to 2014. You can read the full study here.

Chelsea Weiskerger, a PhD student at Michigan State University who co-authored the report, says the lower E. coli numbers mean that beaches are cleaner and safer for recreational use.

Lake Superior is cold, deep and clear. But it’s no longer the clearest of the Great Lakes.

Lakes Michigan and Huron have gotten clearer, bumping Lake Superior to number three.

Scientists have been able to figure how much clearer by using satellite imagery.

LANSING, Mich. (AP) - Michigan officials say after years of planning, they're ready to put in place a strategy for controlling the spread of invasive species in the state's waterways.

The plan is described in the annual "State of the Great Lakes" report released Thursday by the Department of Environmental Quality.

Aquatic invaders such as quagga mussels cost the region hundreds of millions of dollars a year.

The newly developed strategy focuses on early detection of new invaders and a rapid response to rein them in.
