Great Lakes

Lakes Superior and Erie have too many sea lampreys.

The invasive fish latch onto big fish like lake trout and salmon and drink their blood and body fluids. A single lamprey can kill up to 40 pounds of fish in its lifetime.

The "gales of November" came early to the Upper Peninsula and Lake Superior. To make things extra interesting, snow hit the ground today too, and more is on the way.

On Tuesday, this stormy weather produced a 28.8-foot wave at the Granite Island buoy located north of Marquette, says MLive chief meteorologist Mark Torregrossa.

Nobody ever thought they would find it: the P-39 fighter plane that Tuskegee Airman Frank Herman Moody, originally of Oklahoma, was flying over Lake Huron when he crashed.

But then, as luck or fate would have it, there was a bad storm on Lake Huron in April of that year, a barge and tug went down, and a cleanup was scheduled.

It was during this cleanup that a set of almost perfectly intact wings were found on the lake's floor.

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.

Standing on the shores of the Great Lakes on a sunny late-summer day, it’s virtually impossible to think of those sparkling waves as a death trap.

But divers have seen what those angry lakes can do to a ship.

Becky Kagan Schott, noted underwater photographer, joined Stateside to discuss what it’s like to document these untouched wrecks.

Antidepressants that people take are building up in the brains of fish like walleye, bass, and perch. Researchers studied fish from the Niagara River, which connects lakes Erie and Ontario.

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

There’s a green bloom of cyanobacteria on Lake Erie again. People who run water utilities and scientists are watching the bloom because the cyanobacteria can produce toxins called microcystins that are dangerous for people and pets. It's what made Toledo’s drinking water unsafe to drink in 2014.

Chris Winslow directs Ohio Sea Grant and Ohio State University’s Stone Laboratory. He says the bloom’s covering about 10% of the western basin.

Most people have heard of a bird or wildlife sanctuary, but fewer are familiar with sanctuaries for shipwrecks.

The Thunder Bay National Marine Sanctuary is one of only 14 national marine sanctuaries in the entire country operated by the National Oceanic and Atmospheric Administration, and it’s situated in the northwest corner of Lake Huron, just off the shores of Alpena.

An Asian carp was caught this summer in a place where it shouldn’t be – beyond an electric barrier meant to keep the species out of Lake Michigan and the rest of the Great Lakes. Now, a researcher at Southern Illinois University is trying to figure out just how it got there.

Recently, a recreational fishing boat on the St. Clair River forced two freighters into a game of chicken by refusing to move out of their path at a point on the river near the Bluewater Bridge in Port Huron.

The first freighter sounded a warning and the fishing boat didn’t move, and the freighter managed to veer out of the way. When a second freighter came along about a half-hour late, the fishing boat headed straight for it.

The Great Lakes are the largest group of freshwater lakes on the planet. But their future is uncertain.

Every year, a Native American group called the Mother Earth Water Walkers treks hundreds of miles around the Great Lakes to raise awareness of water issues in the region.

This year, the group is making its 2,000 mile trip from Duluth, Minnesota to Matane, Quebec.

Stateside producer Mercedes Mejia caught up with the group near Leamington, Ontario, and learned that the walk is more than a call to action. For many, it's a spiritual journey that connects them to each other and to other indigenous communities.
