Water


On July 16, 2012, one of several signs posted along Lake Mendota near the Memorial Union Terrace at the University of Wisconsin-Madison warn against swimming during the presence of toxic blue-green algae in the water. Known as cyanobacteria, the algae are photosynthetic bacteria that live in colonies, typically in lakes with excess fertility. (Photo by Jeff Miller/UW-Madison)
On June 7, the summer’s first blue-green algae bloom turned much of Lake Mendota a thick, putrid green color. Researchers at the University of Wisconsin–Madison Center for Limnology concluded that several factors — including run-off from local farms, multiple days with hot temperatures, and low winds — created near-perfect conditions […]

Zebra mussels in Lake Mendota: the new kid in town

But both pay homage to the Great Lakes freighter named Edmund Fitzgerald, which, 40-years-ago today (10 November 1975), disappeared on Lake Superior with all […]

An aerial view of the Yahara watershed
Minnesota may be called the Land of 10,000 Lakes, but Wisconsin probably has more. Likely, it has more. Or maybe it doesn’t. It’s a matter of opinion.
