Swimming Upstream: Toxins in Great Lakes fish (part 7)

Advice on cleaning fish to cut away fat and remove certain contaminants.

Today, we wrap up our series, Swimming Upstream. Dustin Dwyer traveled all around the Lower Peninsula to gather stories for this series. And today we have a story we wish we didn't have to do. It's the story of toxins in our fish. 

Here's Dustin's story:

A few weeks ago, Joe Bohr got a surprise. He's a researcher for the Michigan Department of Environmental Quality. He was looking at some numbers for PCB contamination in carp caught in canals in St. Clair Shores.

Scientists: Enough talk, Great Lakes and Mississippi should be separated

Asian carp DNA detections (red) in the Chicago waterways upstream and downstream of the electric fish barriers in 2009 and 2010, according Jerde et al., 2011.

The Great Lakes and the Mississippi River basin are connected, but it's an artificial connection.

Around the turn of the last century canals and channels were dug that reversed the flow of water.

Waters that used to flow into Lake Michigan now flow into the Des Plaines River and eventually into the Mississippi.

The reversal was a way of separating Chicago's sewage from its drinking water supply.

And with more than 2 billion gallons of water a day flowing out of Lake Michigan, it's the largest diversion of Great Lakes water.

Undoing what was done around a hundred years ago has been considered crazy talk because of the expense involved, but some scientists are now embracing that idea.

In a new paper released in the Journal of Great Lakes Research, four lead scientists (Jerry Rasmussen, Henry Regier, Richard Sparks, and William Taylor) argue that the costs of permanent separation of the Great Lakes and Mississippi River Basin are worth it.

This week, we've been hearing stories about fish, for our series "Swimming Upstream." For today's story, Dustin Dwyer paid a visit to some researchers with the Department of Natural Resources. The DNR tracks fish populations at sites around the state. Dustin went aboard with the team on Lake St. Clair, and sent us this report.

Power plants killing millions of Great Lakes fish every year

The Bay Shore Power Plant on Maumee Bay in Lake Erie. Lake Erie Waterkeeper Sandy Binh says this power plant is "probably the largest fish-killing plant in the Great Lakes."

Power plants around the region are responsible for killing hundreds of millions of fish each year, according to an investigative report from the Chicago Tribune.

The Tribune's environmental reporter, Michael Hawthorne, looked at thousands of pages of industry reports documenting fish kills obtained through the Freedom of Information Act.

Hawthorne reports that the reports "highlight a threat to the Great Lakes ecosystem that has largely gone unaddressed for years."

Climate change & Great Lakes restoration

There’s an enormous project underway to clean up and protect the Great Lakes. It’s called the Great Lakes Restoration Initiative. People are doing things like cleaning up toxic hot spots... restoring wetlands... and trying to keep Asian Carp out of Lake Michigan.

Melinda Koslow is with the National Wildlife Federation. She’s an author of a new report on how climate change might affect these projects. She says scientists are finding the climate in the Great Lakes region is already changing.

Raising Lakes Huron, Michigan costly

Water levels in Lake Michigan have been low for years. Would dams at the upper end of the St. Clair River raise lake levels, and would they be worth the cost?

TRAVERSE CITY, Mich. (AP) - A new report says it would be technologically feasible to raise water levels in Lakes Huron and Michigan to make up for drop-offs caused by more than a century of dredging and other human activity.

But the report obtained by The Associated Press says it would take decades to accomplish the task and the price tag could exceed $200 million.

The study is scheduled for public release Friday. It was conducted by a team of engineers and scientists for the International Joint Commission, a U.S.-Canadian panel that advises both nations on Great Lakes issues.

They're trying to determine whether it would be worthwhile to place underwater dams, gates or other structures at the upper end of the St. Clair River to reduce the volume of water escaping Lake Huron.

Rip currents threaten the lives of Great Lakes swimmers

Rip current mechanism: breakers cross sand bars off the shore, the water travels back to sea through the gap in the sand bars, creating a fast "rip" current

This week, state lawmakers will discuss what can be done to better protect people from rip currents on the Great Lakes. It’s estimated that about 30 people drowned in the Great Lakes last year because of rip currents. 

Rip currents form when powerful winds or surges of water press along the shoreline.  The water must eventually flow back out.  When it does the rip current created can prove too strong for even the best swimmer to escape.

Kayaker who shuns lifejacket, ends up needing lifejacket

Kayaking can be a great way to experience the Great Lakes.

Sometimes getting caught can be a good thing.

A kayaker on the Manistee River in the northwestern Lower Peninsula recently was stopped by officers who were checking canoes and kayaks for safety equipment. The Department of Natural Resources says a man was adamant that he didn't need a life jacket or any other flotation device.

Just moments later, he flipped his kayak and landed in 51-degree water. Conservation officers Steve Converse and Sam Koscinski pulled him into their patrol boat and took him to shore.
