Researchers search for clues to toxic algae blooms

Read the full story from Minnesota Public Radio.

From Washington Lake in southwest Minnesota, to Lake Minnetonka, to Helen Lake in northern Minnesota, toxic blooms of algae are again surfacing on the state’s lakes.

They’re suspected culprits in one case of human illness and two dog deaths so far this summer.

When lake temperatures warm, blue-green algae thrives, often forming in thick, pea-soup colored blooms that spread out across the surface of lakes.

The algae has been present in Minnesota since at least the turn of the 19th century. But it’s only recently exploded on the public’s radar. It’s believed to have killed 20 dogs in Minnesota since 2004, including this August at Lake Minnetonka and at Lake Geneva, near Alexandria, Minn.
