This winter eighty percent of the fish in the Big Eau Pleine Reservoir in Marathon County died due to oxygen starvation. An aeration system installed in 1980 solved the problem until recent years. But agricultural runoff and five years of drought overwhelmed the aerators. In Part Two of a series, In Wisconsin Producer Art Hackett explores the reasons why this winter was so deadly.
Big Eau Pleine Reservoir fish kill has ’domino effect’

Biologists predict sizeable fish kill on Big Eau Pleine Reservoir
A medical breakthrough at the UW Madison and its Waisman Center could help people with the metabolic condition known as PKU stay on the strict diet required to prevent brain damage. Follow a patient with the condition as he follows a new diet, eating foods discovered by scientists at the UW, and find out what the change means to him and potentially thousands of other people affected by PKU.
The North American Cougar is known by a plethora of names: the mountain lion, the panther, the puma. This elusive animal once roamed across all of North America, but in the eastern United States, only a small remnant population of cougars survives in Florida. There is however, a healthy population of cougars in the Western states and the numbers are growing. Could the cougar slowly make its way eastward?
The cougar disappeared from Wisconsin in the early 1900’s, but every year there are reports that this animal has returned. On January 19, a trapper in Rock County claims to have come upon a cougar. DNA analysis of blood and urine from the site indicate that indeed, a cougar was in the area. Wisconsin’s Department of Natural Resources is charged with investigating sightings of cougars in the state, to determine if the animal has returned. We spend time with one of the DNR’s “animal detectives” who analyzes the evidence: tracks, photos and video recordings of possible cougar observations in the state.
Schoeneberg Marsh (off Highway 22) is a wonderful spot for spring birding. One might catch a glimpse of as many as a dozen species of ducks, plus a host of other animals. Historically known as part of the Empire Prairie, it attracts birds to the shallow wetlands, sedge meadows, oak savannas, both remnant and restored prairies, and deep-water marshes. Large spring and fall migrations of waterfowl, including Tundra Swans, make these sites popular with bird watchers.
Patty Loew:
Welcome to "In Wisconsin". I'm Patty Loew. This week, a medical breakthrough at the UW provides hope for people who risk depression or brain damage if they eat protein, and continuing coverage on the huge fish kill in Marathon County.
Man:
If we try to save water here, some other reservoir is going to suffer.
Patty Loew:
See what impact it could have on the Wisconsin River.
Plus, another cougar sighting "In Wisconsin".
Man:
I was surprised when I opened up my email and I thought, well, darn, those do look like cougar tracks.
Patty Loew:
What it takes to confirm a sighting of this elusive big cat next on “In Wisconsin.”
Announcer:
Major funding for "In Wisconsin" is provided by the people of Alliant Energy, who bring safe, reliable, and environmentally friendly energy to keep homes, neighborhoods, and life in Wisconsin running smoothly. Alliant Energy, offering energy saving ideas on the web. And, the Animal Dental Center of Milwaukee and Oshkosh, a veterinary specialist working with pet owners and family veterinarians throughout Wisconsin, providing care for oral disease and dental problems of small companion animals.
Patty Loew:
We begin our program with continuing coverage on the massive fish kill we first reported last week during “In Wisconsin.” It involves the Big Eau Pleine reservoir in Marathon County. The DNR estimates 80% of the fish were killed. Anglers are angry and want to know why. “In Wisconsin” reporter Art Hackett shows you why there is plenty of blame to go around near Mosinee.
Art Hackett:
Over the winter, department of natural resources biologist Tom Meronek watched the fish die off in the Big Eau Pleine reservoir.
Tom Meronek:
There was a lot of game fish, pretty good size walleyes, some of them alive, some dead.
Art Hackett:
The cause of death was low oxygen general levels in the water. The fish suffocated. Anglers like Pepe Gonzalez have watched the dead fish pile up on the shore and searched for someone to blame.
Pepe Gonzalez:
There’s gotta be someone at fault. If you ask me, they pulled the water down too far and they couldn't go anywhere. They have that big suction in the center, they can't live on no oxygen.
Art Hackett:
When he says “they,” he means the Wisconsin Valley Improvement Company. They control the dam and flow of water out of the reservoir. The flow in from the Big Eau Pleine River is, of course, controlled by mother nature. During the past five years, mother nature has handed northern Wisconsin a drought. The drought is only part of the story.
Tom Meier:
Since 2000, we've seen dramatic changes in our rainfall events, so this year we went into the winter probably the lowest that I've seen it in 26 years of being here. We froze up early. The minute it ices over, you start to lose oxygen.
Art Hackett:
This aeration system was installed more than 25 years ago to cope with low oxygen levels, but it's overwhelmed by the oxygen-eating organic sediment from farm run off.
Tom Meier:
In the past, when the aerator was set up, in the agricultural community, generally manure was spread on the fields late, late winter, it was in solid form.
Art Hackett:
Now, farms spread liquid manure, and farms are bigger.
Tom Meier:
So they don't have the capacity at the current time to handle a lot of that liquid manure, so it has to be put on the landscapes sometimes mid-winter so when you have a melt now it comes directly into the system.
Art Hackett:
It comes in real fast?
Tom Meier:
It comes in very fast in hundreds of thousands of gallons, and it can affect the system dramatically very quickly.
Tom Meronek:
It gets huge algae blooms in the summer. Obviously that's an indicator that there's a large amount of nutrients coming into the system.
Tim Garrigan:
I think the aerator is just a diversion tactic.
Art Hackett:
He represents a homeowners group challenging the practices of Wisconsin Valley Improvement.
Tim Garrigan:
We need more water, we need clean water, more water. This might take years to come back from this.
Art Hackett:
WVIC uses the Big Eau Pleine to provide a steady flow through dams further down the stream on the Wisconsin River.
Tim Garrigan:
In july, they like to in anticipation for fall rains, they like to start opening up the gates. 16, 20 inches is not uncommon. We feel that if we can take that bell curve that they use and kind of put a little leveling playing surface on it, we can both be happy.
Tom Meronek:
WVIC, last summer, didn't specifically manager this reservoir so it would end up as low as it did. They pretty much operated as they normally would and we got hit with a real dry spell at the end of the summer and it didn't bring the water levels up.
Art Hackett:
The current gate-setting on the dam is the minimum WVIC's federal permit will allow.
Tom Meronek:
They've got their gate open about an inch.
Tom Meronek:
That's pretty much equaling in-flow of what's coming into the reservoir so you're just balancing it out. It’s not going up, not going down.
Art Hackett:
Completely shutting the gate would create problems downstream.
Tom Meier:
There's problems with fish kills here on the plain. If we try to save water here, some other reservoir is going to suffer, so it's a complex system.
Tim Garrigan:
Let's say we're going to pretend we're going to have a 15-year drought. Are we just going to kill the fish until there's' nothing left? 80% are dead now. Do we just kill off the 20% next year? I mean, we have no plan.
Art Hackett:
But the DNR’s Tom Meronek says his agency does have a plan figuring out how to better control farm runoff upstream.
Tom Meronek:
We have to continue that process and find out, you know, pinpoint what nutrients and where they're coming from that's creating the problem that we're seeing out here.
Patty Loew:
The federal government allows for the license on the dam to be revised every five years. The Big Eau Pleine homeowners group wants their concerns addressed during the next license review in 2011.
Patty Loew:
Now, we turn to a medical breakthrough at the University of Wisconsin 10 years in the making. Imagine living in the dairy state and not being able to eat cheese, eggs or meat. For some people, eating those basic foods can cause depression, even brain damage. This month UW researchers are reporting the success of revolutionary new foods made from whey, a cheese byproduct. We show you the ground-breaking research in Madison.
Frederica Freyberg:
As though the transition from womb to world isn't startling enough, in Wisconsin, and every other state, a needle prick of the heel is the part of every baby’s first day on earth. This blood test screens for a number of conditions, including the genetic disorder called PKU. People with PKU. lack the enzyme needed to digest phenylalanine, an amino acid found in proteins. About 1 in 10,000 babies in the US test positive and must be switched to a special formula because even the protein in milk causes brain damage and severe retardation in people with PKU. 10-year-old Jessie Zimmerman whips up a batch of her special formula, the liquid nutrition she's taken since she was a newborn. It provides nutrients she needs to grow without the phenylalanine that could damage her brain. Anne Zimmerman says when newborn Jessie tested positive, it was hard, but not all together unexpected. The condition runs in her family.
Anne Zimmerman:
It was really, really kind of scary and sad because my maternal aunts and uncle who have PKU are severely and profoundly retarded.
Woman:
Everything okay?
Man:
Yep.
Frederica Freyberg:
But unlike 60 years ago, doctors today know for people with PKU a diet restricting protein prevents that brain damage. Still, in today's world such extreme restrictions seem unimaginable.
Anne Zimmerman:
Jessie has never eaten meat or cheese or fish. She’s never eaten pizza, hamburgers.
Frederica Freyberg:
Instead, along with her formula, she eats specially-made low protein products in very precise amounts.
Anne Zimmerman:
Porridge, spaghetti, her special crackers.
Jessie Zimmerman:
Sometimes it's challenging, like bringing -- telling everyone like having special food for cold lunch and having to tell everybody everything about it.
Frederica Freyberg:
Still, Jessie sticks to her diet and gets lots of help from her family, but according to experts it's the teen years that many people with PKU start to stray.
Denise Ney:
After about ten or twelve years of age, more than half of the people with PKU really can't follow their diet.
Frederica Freyberg:
Just ask Matt Cortright.
Matt Cortright:
When I was at home, I didn't have a problem, but when I was out or when I was in school it was hard to have self control to say, okay, I can't have that. It looks really good, it smells really good, but I can't have that.
Frederica Freyberg:
He said he was on a strict PKU diet from the time he was a newborn through his grade school years, but went completely off it from age 14 to 19, he suffered the consequence, he developed neurological damage that caused a disabling movement disorder and seizures.
Greg Rice:
There's that transition between parents making all the decisions to the teenager really having to take over the disorder and take responsibility for the disorder themselves.
Frederica Freyberg:
Doctors know people with PKU must stay on a strict diet, but people with PKU often cannot, even knowing the risks because the foods they eat are different and difficult.
Makayla Crownhart:
So then every day people with PKU, they really have to consider what they eat, something as simple as broccoli and they often have scales in their homes of which they weigh out their foods.
Frederica Freyberg:
And the formula? PKU nutritionists allowed me a taste test.
Frederica Freyberg:
So this is what people need to drink to supplement their protein.
Woman:
Right.
Frederica Freyberg:
And this is like they drink it like anyone would drink milk.
Woman:
Right. They often call it milk.
Frederica Freyberg:
People with PKU may often call it milk, but it doesn't taste like any milk I've ever had. While that formula is a fact of life for people who have PKU, what if it tasted better, would that help patients stick to the diet? The answer to that question is where research and real life come together. Five years ago Dr. Mark Etzel was researching ways to isolate useable proteins from the whey that comes from the cheese-making process. He purified one particular whey protein, making it free of phenylalanine, the amino acid that causes damage in people with PKU. He was on to something big, and parents of children with PKU jumped on it.
Mark Etzel:
I wrote this article, and then I started getting emails from mothers and fathers saying, oh, thank God you're working on this. This is -- I pray at night that your research will be successful. I'm like, what's this? I mean, I'm used to publishing papers in science journals and going to conferences, I don't get emails from mothers and fathers saying they pray at night about my research.
Frederica Freyberg:
Soon, connections across the university campus started clicking. PKU specialists, dairy researchers and a professor of nutritional science got to work to literally bring a science discovery to the dinner table.
Denise Ney:
I never experienced that, to work on something where the direct connection with people that the disease with the condition, the people you're trying to help is there.
Frederica Freyberg:
Professor Denise Ney conducted studies on mice with PKU to test whether the new protein was safe and provided enough nutrition. Her studies showed that the new protein actually lowered the levels of dangerous phenylalanine in the blood and brains of mice compared to the traditional PKU diet. Next, Cathy Nelson started making human food with the new protein.
Woman:
Oh, yeah. I think this pudding is pretty good.
Frederica Freyberg:
Hmm. This is good.
Frederica Freyberg:
Nelson's recipes included pudding, orange juice.
Frederica Freyberg:
That kind of tastes like Tang or something.
Frederica Freyberg:
But it didn't much matter for people like me without PKU liked the tastes of the new foods. They had to be tested for safety for PKU patients, so the team conducted human trials on the new products.
Matt Cortright:
As far as taste, texture, how it's handled in the stomach, it was all a lot better.
Frederica Freyberg:
Matt Cortright was among the people tested. He was on the diet for eight weeks, the longest period for any of the subjects. He had regular medical exams and blood tests, even brain scans to measure the safety of the foods.
Greg Rice:
His levels have been stable, and he is enjoying the taste and he's able to take it better than some of the other foods we tried with him in the past.
Sally Gleason:
Finally this was a product that people would like to eat, and so they would be more likely to get the protein that they need.
Denise Ney:
Everything looks promising, and particularly that the diet is so acceptable by the subjects who have tested it for us and, you know, it could be promising medically, but if you can't eat it, people aren't going to.
Frederica Freyberg:
So at the end of the trial, Cortright met with the research team giving them a thumb's up on the taste of the new foods and ideas for more items.
Matt Cortright:
If something can be made kind of like a chip.
Frederica Freyberg:
Cortright followed the research diet faithfully and traveled from his home in Wausau to take part in tests and medical exams in Madison. Why would he take part in such a big way in this research?
Matt Cortright:
A number of reasons, so people don't have to go through what I went through.
Frederica Freyberg:
At 10, Jessie wasn't old enough to take part of the human trials of the new foods, but it has been deemed safe enough for her to take a taste.
Woman:
Is it good?
Frederica Freyberg:
Chocolate pudding is not something that Jessie Zimmerman has ever tasted, getting such products on store shelves would expand what she and others with PKU can eat. It could replace the nutrient-rich formula with something tastier and more convenient. It could help people with PKU stay on their diet, and that is the whole point.
Mark Etzel:
Being able to have your research go from the laboratory at the university into family's homes where mothers and fathers and children benefit, you know, it's just rare, and it's like one of the great moments of my career.
Frederica Freyberg:
The university has patented Dr. Mark Etzel’s whey protein discovery. A Massachusetts company wants to sell snack bars, pudding, and sports drinks based on the discovery here in Wisconsin. If you'd like more information, just go to our website at wpt.org/InWisconsin.
Patty Loew:
An animal that disappeared from our state more than 100 years ago is on the prowl again in Wisconsin. These are pictures taken in early March after the DNR cornered a cougar near Spooner. They darted the animal with a tranquilizer gun, but it didn't immobilize the large cat and he escaped. Experts didn’t want to over-stress him, so they called off the search, and the cougar hasn't been seen since. Jo Garrett investigates other recent cougar sightings to see if experts can determine if they're the real deal "In Wisconsin".
Jo Garrett:
For more than a century Wisconsin's woods have been absent of this sound. That yowl belongs to this animal, the North American cougar, a.k.a., the mountain lion, the panther, the puma. All these different names describe the same big cat.
Man:
This was the one reported to me being near Moose Lake which is just east of Hayward.
Jo Garrett:
We sat down with Adrian –. He’s the DNR employee who investigates these sightings. We wanted to find out what kind of reports he gets. He is well-suited as an animal detective. He has a master's degree in wildlife biology and decades of experience tracking animals. What is he looking for? To start, like any detective, he needs evidence.
Adrian:
Unfortunately, probably less than 10% of these can we actually evaluate something where we have pictures of tracks or pictures of animals or can go back to the site and look for signs, so probably less than 10% of time can we make any type of evaluation.
Jo Garrett:
But in those cases, what are the clues that point to a hoax or separate cougars from other suspects? Here's one.
Adrian:
Well, here's an animal that was suspected as being a cougar, but something noticeable on this animal is the back of the ears, that is very characteristic of a bobcat is this big white spot in the back of the ears. A cougar ear would be just dark black or grayish, this wouldn't be a white spot. That tells me that's a bobcat, not a cougar.
Adrian:
This picture was sent to me in November of 2006 and reported cougar observation near Butternut, Wisconsin. I get this picture and something doesn't look right about it to me. Its coloring tells me it’s an obvious cougar, it's got the long tail, the tan-ish coloration, white underneath, darkish colors around his face. All of that says cougar to me, but the vegetation wasn't right, and it looks like the trees look like lodgepole pine.
Jo Garrett:
So we don't have that here?
Adrian:
No. We don't have lodgepole pine occurring naturally, we have white pine and some scotch pine planted in Wisconsin, but we don’t have lodgepole pine. Then the under-vegetation looks like bitter brush or sage brush. It's not likely a Wisconsin scene.
Jo Garrett:
Not likely, but somehow familiar.
Adrian:
Right away with this picture I thought there's something -- I have seen this scene before and then went back through my files, and from two years ago I came up with this other picture. Initially somebody said, this is near their home in the Baraboo hills. I don’t think we have mule deer in the Baraboo hills, and this is an obvious mule deer. The white rump and the black tip on the tail like that, white tailed deer would have just a tan-ish rump. It's the exact same scene. The same pine tree here with the cavity right here, the same downed tree in front. So it may be that we've got part of a picture of a deer that walked by, and then another picture of the cougar and they just pasted it together.
Adrian:
This is an animal that a person saw swimming on the chippewa flowage, and they were convinced that what they saw was a black panther. What we're looking at there, looking at the sizes of the tree, the size of the roots, this is a fisher, a large member of the weasel family. They're convinced this is a 70, 80-pound animal. This is a set of tracks that were taken near Milton in Rock County. I was surprised when I opened up my email and looked at the pictures, and thought, well, darn, those look like cougar tracks.
Jo Garrett:
Here's why.
Adrian:
A set of tracks, about three inches long, three inches wide, very large pad, we have those 3 even-size lobes at the back of the pad. We've got a bit of an indentation at the top of the pad. We have a leading toe that sticks out ahead of the other toes. The overall size is the typical size of a cougar. I measured the width of the pad as 43 centimeters and that would put it at the size range of an adult female cougar or young male.
Jo Garrett:
In addition to the tracks, it's the stride, the length between the tracks, and what's called the bounding pattern.
Adrian:
This is a very typical cat bounding pattern. It's called a 1 x by 3 bound.
Jo Garrett:
That spells cougar.
Adrian:
All of those are indicative of a cougar-size cat.
Jo Garrett:
So a maybe?
Adrian:
I would call it a probable.
Jo Garrett:
Indeed, several weeks later, DNA tests from blood that the cat left at the scene confirmed it, it's a cougar. They also confirmed it's a wild North American cougar, not an exotic pet let loose on the landscape.
Adrian:
We believe that cougars may re-establish in Wisconsin. We have habitat that's suitable for cougars, we have a high deer population that's going for their source of food. There are populations in South Dakota and we’re in the dispersal range of it. It's one of the things as an agency we want to be on top of that we want to be able to detect them and document their presence and monitor their populations.
Patty Loew:
The DNR wanted to fit the cougar spotted near Spooner with a tracking collar but weren't able to capture it. If anyone sees a cougar, they're urged to keep their distance and try to preserve the tracks so the sighting can be verified.
Patty Loew:
Now here's some of the reports we're working on for next week’s edition.
Liz Koerner:
This is Liz Koerner. Last year, Hollywood came to Wisconsin to film "Public Enemies.” The state lured the filmmakers with incentives. Did it pay off? See how new rules playing in Wisconsin.
Man:
What started as a small incentive has turned into a competitive, what we call a race to the bottom.
Andy Soth:
This is Andy Soth. It's over 60 teams of UW students, with $100 dollars to create a new product. It’s the Wiscontrepreneur challenge.
Woman:
Innovative.
Jo Garrett:
This is Jo Garrett, Wisconsin's Apostle Island lighthouses going to get a facelift from Uncle Sam.
Man:
When we first arrived here, the building was in quite a state of disrepair, but it's over 100 years old.
Jo Garrett:
See what this new infusion of money will mean for some of our state's historic lighthouses.
Patty Loew:
Join us for "In Wisconsin" next Thursday at 7:00 on Wisconsin Public Television.
Patty Loew:
That's our show this week. We leave you with a misty morning on the marsh near Arlington in Columbia County. It's a wonderful spot for spring birding, as large migrations of tundra swans and more than a dozen species of doves make it popular. Have a great week "In Wisconsin"
