As Great Lakes advocates lobby Congress this week, a new report details how the federal government and states plan to fight algae blooms in Lake Erie.

The U.S. Environmental Protection Agency’s plan targets phosphorus, the main cause of the blooms.  It summarizes agendas from Michigan, Indiana, Ohio and Pennsylvania.

Invasive or not? A Great Lakes Puzzle

Around the Great Lakes, millions of dollars are spent to fight invasive species like Asian carp. They cause a lot of damage. But when scientists discover a new animal or plant in the region, it’s not always clear if it’s harmful - or helpful.

That debate has begun over a shrimp.

The bloody red shrimp is roughly the size of a pencil eraser. They came to the Great Lakes around 2006, hitching a ride in the ballast water of cargo ships from the Black Sea.

Since then, they’ve worked their way into all of the Great Lakes except Superior.
