Lake Superior

Gale warnings on the northern Great Lakes are in effect until late tonight, according to the National Weather Service.

Strong winds from the southeast will cause gusts that may exceed 40 miles per hour on the northern coast of Lake Michigan.

Most of Lake Superior is also under gale force winds advisory. 

The National Weather Service expects waves up to 19 feet.

They say there is an increased threat of lakeshore flooding in coastal areas throughout the weekend.

This week on Points North, a decline in lake whitefish is pushing tribal commercial fishermen to the northern edge of their treaty waters. Plus, we look at test results for PFAS contamination in Michigan’s public water and meet a funk band from Boyne City.


Today on Stateside, we hear from the president of the State Board of Education following an MSU report’s findings that Michigan leads the country in declining school funds. Plus, we talk with the CEO leading the charge on digital license plates in Michigan.

Lake Superior, the largest freshwater lake in the world, is awe-inspiring on many levels. But it’s also challenged. Though it seems pristine, a couple centuries of exploitation have taken their toll.

A new book Sustaining Lake Superior: An Extraordinary Lake in a Changing Worldpublished by Yale University Press, traces the history of the lake and some of the indignities it's suffered at the hands of humans.

You've probably heard of the Trail of Tears, when more than 4,000 Native American men, women, and children died in a series of forced removals from their homeland in the Southeastern U.S. to present-day Oklahoma. They were members of the Cherokee, Seminole, Muscogee, Chickasaw, and Choctaw nations.

But there was another Trail of Tears much closer to us. It's the Sandy Lake Tragedy of 1850. Hundreds of Ojibwe people died as the U.S. government tricked them into leaving their homes in the Upper Great Lakes and traveling to northern Minnesota. 

It's known as the Chippewa Trail of Tears, and the Wisconsin Death March.

Crystal clear Great Lakes may not be so healthy

Here's a question for you lovers of the Great Lakes: Which lake is the clearest? You probably guessed Lake Superior. Well, that was true for a long time. But a recent study found that other lakes are now number 1 – and 2.

At Brighton Beach outside Duluth, the waters of Lake Superior are stunningly clear. Looking into about six feet of water, it’s easy to see smooth rocks at the bottom.

But Lake Superior has lost its long-held title as the clearest of the Great Lakes. A recent study showed that lakes Michigan and Huron have changed drastically.

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.

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.

Soo Locks repairs causing shipping delays

A repair project at the Soo Locks in Sault Ste. Marie is taking longer than expected. Workers drained the MacArthur Lock two weeks ago to fix a broken gate but then discovered additional problems.

Engineer Kevin Sprague says the lock was built in 1943 and is showing its age.

“Structures start to get fatigued (and) a lot of different issue start to happen. We’re seeing an increase in the amount of maintenance we have to put into these locks every year to keep up with their age.”

Sprague says he hopes repairs will be finished by August 19th.

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.

Before the ice melts, let's take time to celebrate one of winter's great gifts: the sea caves at Apostle Islands National Lakeshore.

Eighteen miles west of Bayfield, Wisconsin is where you can find the island chain in Lake Superior. The islands and the ice have created a breathtaking natural art gallery.

OK, maybe you’ve seen the picture: sunny, 80-degree weather and people lying out in the sand – maybe even getting sunburned on the shores of Lake Superior. And maybe, there in the background, huge pieces of ice still floating around in the lake.

John Lenters is a climatologist at Ann Arbor-based LimnoTech, an environmental consulting firm.

Lenters says says because of the size and depth of the lakes, it will take a while for them to warm up after the extremely cold winter.

The ice is melting, but Lake Superior warms up slowly before it hits 39 degrees Fahrenheit.

Researchers have found evidence of a small invasive fish in southern Lake Michigan for the first time. It could be an early warning that the species may be spreading and could migrate into the Mississippi River system.

The Eurasian ruffe entered the northern Great Lakes 25 years ago in the ballast water of a ship in Duluth harbor.
