Great Lakes

The Great Lakes are the largest freshwater system on the Earth's surface, home to a fragile fishery, and delicate shoreline beaches and dunes. They are also central to northern Michigan tourism, economies and our way of life. 

Lake Superior is the largest freshwater lake in the world by surface area, and it has something the other Great Lakes don’t — stable populations of mostly native fish species.

But scientists say a key fish in Superior’s food web is now in trouble because of mild winters and an appetite for caviar in Europe.

Researchers have discovered a widespread infestation of quagga mussels in Crooked Lake near Petoskey. It’s the first time the mussels have been reported in an inland lake in Michigan.

Quagga mussels spread rapidly through the Great Lakes in the 1990s and eventually displaced their cousin, the zebra mussel. Kevin Cronk from the Tip of the Mitt Watershed Council says quagga mussels have a wide range and reproduce very quickly.

What makes someone want to live on an island?

Loreen Niewenhuis pondered this question in her book, A 1,000 Mile Great Lakes Island Adventure, which recounts her journey traveling to many of the islands in each of the Great Lakes. This is the third in her Great Lakes Adventure series and the last time she spoke with us she had just completed hiking the shorelines of all five Great Lakes.

The Great Lakes Compact is facing its first big challenge. Signed into law in 2008 by the leaders of eight Great Lakes states and two Canadian provinces, the compact says only communities in the Great Lakes Basin can draw their drinking water from the lakes.

The challenge to the compact is not coming from thirsty states like California or Texas. It comes from Waukesha, Wisconsin – a suburb of Milwaukee that’s only about 15 miles from Lake Michigan.

Michigan Attorney General Bill Schuette says the days of an energy pipeline running beneath the Straits of Mackinac are numbered. But, a task force led by Schuette does not recommend that day should come anytime soon.
