Great Lakes

The Great Lakes are the largest freshwater system on the Earth's surface, home to a fragile fishery, and delicate shoreline beaches and dunes. They are also central to northern Michigan tourism, economies and our way of life. 

A doctor in Gaylord will perform a CAT scan this weekend on a 20-foot, waterlogged piece of wood. The procedure is being contracted by a group of underwater explorers hoping to uncover a famed 17th Century Great Lakes shipwreck.

Explorers are paying Otsego Memorial Hospital an undisclosed dollar amount for the procedure, which they hope will reveal enough tree rings in the timber to date it.

Dead Fish Good Sign For Anglers, Not Swimmers

Jul 17, 2013

Just in time for peak travel season dead fish have been washing ashore on parts of the Sleeping Bear Dunes National Lakeshore.

Kevin Skerl, the chief of natural resources at the lakeshore, says it’s not a big concern.

“This is something that happens every year. It’s just a question of if the conditions are such that the dead fish are showing up on beaches where people are,” says Skerl

Oil Pipeline Spurs Rally At Straits

Jul 12, 2013

Environmental groups want an oil pipeline company to replace a sixty-year-old line that runs under the Straits of Mackinaw. They’re holding a rally at the Straits this Sunday.

Beth Wallace with the National Wildlife Federation says there have been leaks in other sections of line 5, not in the part that runs under the Straits.

“You know this pipeline is not spill proof. And an expansion of a sixty year old pipeline that runs through some of the most sensitive areas in the world is not the direction that we should be going,” Wallace says. 

Divers Dig To Bedrock: The Griffin Not Found

Jun 21, 2013

The State of Michigan archaeologist says there does not appear to be a vessel buried where underwater explorers had hoped to uncover a 17th century shipwreck this week in northern Lake Michigan.

Explorers have been looking for the wreck of the Griffin off the coast of the Upper Peninsula’s Garden Peninsula.

State Archaeologist Dean Anderson says two things originally drew explorers to the site: acoustical surveys of what appeared to be a ship buried in mud, and a beam of wood sticking up into the water.

There have been some hiccups for underwater explorers and archaeologists this week in northern Lake Michigan hoping to identify the 17th Century ship of the famous French Explorer Robert de La Salle. But there’s good reason for optimism that his schooner, The Griffin, has been found buried in the mud in about 50 feet of water off the coast of the U.P.’s Garden Peninsula.

UPDATE: The artifact recovered by Great Lakes Exploration Group was a block of wood a little more than a foot in length. It appeared to have been hewn on at least one side and was blackened evenly on all sides, almost like wood charred in a fire. Archeologists on the dive had little to say about the object. They will continue to focus their efforts around the beam of wood that was originally found protruding from the bottom of the lake.

As summer water temperatures warm-up, more people are enticed into playing in the big waves. And warnings about dangerous currents are being posted at more beaches.

The number of people who have drowned in the Great Lakes or been rescued has gone up in each of the last three years. And researchers are testing ways to better forecast dangerous nearshore currents.

Nearly Drowned

UPDATED 6/4/2013 with corrected length of legal dispute.

The State of Michigan has issued a permit for a major archeological dig in Lake Michigan. It could uncover the oldest shipwreck in the Great Lakes.

Underwater explorers have been given the go-ahead to dig up bottomlands off the coast of the Garden Peninsula near Green Bay. They’re in search of the French fur trading ship Le Griffon, which went down in 1679.

Recently we reported how native fish are doing really well in one of the Great Lakes. The fish involved are not exactly well known species. But there is one that’s a household name in lakeshore communities and its success is sparking some scientific debate.

A fish with a cult following
Food and travel writers who visit The Cove seldom forget to mention the Chubby Mary. It’s a Bloody Mary with smoked chub in it. Mario Batali even put a photo of the cocktail on Bon Appetit’s website along with his endorsement.

It might surprise you to hear that some native fish are doing really well in one of the Great Lakes. For years now, we’ve heard bad news about the lakes. Most of it has to do with invasive species getting into the lakes and wrecking the food web. One writer memorably called it a slow-moving underwater wildfire.The recent swing in the other direction is so dramatic scientists are a bit puzzled and can’t explain what’s happening.

Regime shift?

Michigan Officials Compliment Underwater Explorers

Apr 5, 2013

Steve Libert has been in court with the State of Michigan pretty steadily since the Engler administration. The disputes involved shipwrecks and who has the right to claim them on the bottom of Lake Michigan and the most recent litgation was closed last year. That’s why he was excited to be recognized by Governor Snyder in a signed tribute to his group, Great Lakes Exploration. All the lawmakers from Northern Michigan signed it too.

Asian Carp Or Silverfin?

Mar 21, 2013

One of the strategies to keep Asian carp out of the Great Lakes is to eat the ones living in the Mississippi River. But finding a market for millions of pound of carp is not a simple matter. It will take more than a name change. We brought a few chefs together at The Great Lakes Culinary Institute to see what they could do with the fish. Hear about that and why harvesting an invasive species isn’t always a wise management strategy.

Lakes Michigan and Huron are at their lowest level in decades. And there is growing pressure to raise the water level with some kind of structure in the St. Clair River. The international commission that manages the Great Lakes is expected to respond to that pressure in February. A report submitted to the commission discourages the idea. This week on Points North we’ll hear about the debate over fixing the water level on Lakes Michigan and Huron.

The City of Waukesha, Wisconsin says it has nowhere else to go for water but to the Great Lakes. This week, it submitted an application to take 10 million gallons a day, on average, from Lake Michigan. But first it would have to meet a number of strict requirements that all eight Great Lakes states have agreed to.

Exception to Ban

The states hammered out a ban on water diversions over several years and the governors signed it and the Congress ratified it five years ago.

Some household toilet water in Grand Traverse County may not be reaching the county septage treatment plant, according to some data unearthed by local officials. Already some recording errors are apparent, but the data makes some officials wonder if a few waterfront homeowners may be pouring sewage into nearby lakes and rivers. If intentional, that would likely be criminal.

Great Lakes Drownings Top 100 in 2012

Jan 7, 2013

More than 100 people drown in the Great Lakes last year and half of them were in Lake Michigan. That’s according to the Great Lakes Surf Rescue Project.

Spokesman Dave Benjamin says one explanation for so many deaths in Lake Michigan is the lake is so long, 320 miles. Most of the wind comes out of the north or the south.

Protecting Mackinac Island's History

Jan 4, 2013

A public hearing is set for next week on Mackinac Island. After that, there will be nothing left but for the city council to decide whether old buildings in the 200 year-old city need protection. Brad Aspey talks with IPR News Director Peter Payette. 

The same company responsible for the worst inland oil spill ever wants to increase the amount of oil going through its pipeline under the Straits of Mackinaw.

Enbridge Energy says it has increased safety inspections since the disaster at the Kalamazoo River a couple of years ago. And the company says the pipeline that runs underwater west of the Mackinaw Bridge is perfectly safe.

But a Great Lakes environmental group isn’t convinced and is trying to stop the plan.

Search For The Wreck Of The Griffon Resumes

Oct 8, 2012

The search for the oldest shipwreck in the Great Lakes resumed this month. The team that says it might have found the wreck, Great Lakes Exploration, is moving ahead after closing a legal dispute with the State of Michigan. They're trying to prove that what they've found in northern Lake Michigan could be a French ship that disappeared in 1679. And they're near the end of what they can do without digging into the bottom of the lake.

Lifetime search

Salmon Struggling To Pass Betsie Bay

Sep 14, 2012

Michigan Natural Resources officials are trying to avoid a mass salmon die-off on Betsie Bay near the mouth of the Betsie River. Extremely low water levels are making it difficult for the fish to enter the river and to spawn.

But Fisheries Biologist Mark Tonello says if people stay away from the area there is enough room for the fish to swim up river.

Meaning Of Test Results For Asian Carp Disputed

Sep 7, 2012

Last week officials in Ohio and Michigan announced they found more evidence of Asian carp in Lake Erie. They didn’t find a carp but numerous water samples tested positive for what’s known as environmental DNA. That suggests Asian carp were in Sandusky Bay this summer. If the exotic fish get into the Great Lakes its expected they’ll further upset the current ecosystem.

For most of us summer winds down this holiday weekend but not if you're a surfer. The surfing season is just starting up. The Dairyland Surf Classic is in Sheboygan, Wisconsin this weekend. It claims to be the largest freshwater surfing contest in the world.

New research this fall will try to find a better way to predict dangerous currents in the Great Lakes. The number of deaths attributed to rip currents has been rising each of the last few summers.

Using Doppler
The experiment will see if Doppler radar can predict rip currents. That’s the same technology that can look at how the air moves inside fast developing storms.
