We’re continuing the series Ten Threats to the Great Lakes. Our field
guide through the series is Lester Graham. He says our next report looks
at where the demand for water will be greatest.


Right around the Great Lakes is where there’s going to be more demand
for drinking water. Water officials say as cities and suburbs grow, so
does the need for water. Some towns very near the Great Lakes say they
need lake water right now, but in some cases they might not get it. The
Great Lakes Radio Consortium’s Christina Shockley reports:


People who live around the Great Lakes have long used the lakes’ water
for transportation, industry, and drinking water. Most of the water we
use, gets cleaned up and goes back in the lakes.


That’s because the Great Lakes basin is like a bowl. All the water used
by communities inside that bowl returns to the lakes in the form of
groundwater, storm water runoff, and treated wastewater, but recently, thirsty
communities just outside the basin—outside that bowl—have shown an
interest in Great Lakes water.


Dave Dempsey is a Great Lakes advisor to the environmental group
“Clean Water Action.”


“We are going to be seeing all along the fringe areas of the Great Lakes
basin all the way from New York state to Minnesota, communities that
are growing and have difficulty obtaining adequate water from nearby
streams or ground water.”


Treated water from those communities won’t naturally go back to the
basin. Treated wastewater and run-off from communities outside the
Great Lakes basin goes into the Mississippi River system, or rivers in the
east and finally the Atlantic Ocean.


The Great Lakes are not renewable. Anything that’s taken away has to be
returned. For example, when nature takes water through evaporation, it
returns it in the form of rain or melted snow. When cities take it away, it
has to be returned in the form of cleaned-up wastewater to maintain that
careful balance.


Dave Dempsey says the lakes are like a big giant savings account, and
we withdraw and replace only one percent each year.


“So, if we should ever begin to take more than one percent of that
volume on an annual basis for human use or other uses, we’ll begin to
draw them down permanently, we’ll be depleting the bank account.”


Some of the citiesthat want Great Lakes water are only a few miles from
the shoreline. One of the most unique water diversion requests might come
from the City of Waukesha, in southeastern Wisconsin. The city is just 20 miles
from Lake Michigan. Waukesha is close enough to smell the lake, but it
sits outside the Great Lakes basin. Waukesha needs to find another
water source because it’s current source – wells—are contaminated with
radium.


Dan Duchniak is Waukesha’s water manager. He says due to the city’s
unique geology, it’s already using Great Lakes water. He says it taps an
underground aquifer that eventually recharges Lake Michigan.


“Water that would be going to Lake Michigan is now coming from Lake
Michigan…. our aquifer is not contributing to the Great Lakes any more,
it’s pulling away from the Great Lakes.”


Officials from the eight Great Lakes states and Ontario and Quebec
recently approved a set of rules that will ultimately decide who can use
Great Lakes water. The new rules will allow Waukesha—and some
other communities just outside the basin—to request Great Lakes water,
and drafters say Waukesha will get “extra credit” if it can prove it’s
using Lake Michigan water now.


Environmentalists are still concerned that water taken from the Lakes be
returned directly to the Lakes, but some say even that could be harmful.


Art Brooks is a Professor of Biological Sciences at the University of
Wisconsin- Milwaukee. He says the water we put back still carries some
bi-products of human waste.


“No treatment plant gets 100 percent of the nutrients out of the water,
and domestic sewage has high concentrations of ammonia and
phosphates. Returning that directly to the lake could enhance the growth
of algae in the lake.”


That pollution could contribute to a growing problem of dead zones in
some areas of the Great Lakes. Brooks and environmentalists concede
that just one or two diversions would not harm the Great Lakes, but they
say one diversion could open the floodgates to several other requests, and
letting a lot of cities tap Great Lakes water could be damaging.


Derek Sheer of the environmental group “Clean Wisconsin” says some
out-of-basin communities have already been allowed to tap Great Lakes
water under the old rules.


“The area just outside of Cleveland–Akron, Ohio– has a diversion
outside of the Great Lakes basin, so they’re utilizing Great Lakes water
but they’re putting it back.”


There are several communities that take Great Lakes water, but they, too,
pump it back. The new water rules still need to be ok-ed by the legislature of
each Great Lakes state, and Congress. Since the rules are considered a
baseline, environmental interests throughout the region say they’ll lobby
for even stricter rules on diversions.

Ten Threats: Coastal Development Pressures

  • Construction along the shorelines can put a strain on natural systems. (Photo by Carole Swinehart/Michigan Sea Grant Extension)

One of the more subtle but relentless threats to the Great Lakes is
coastal development. Condos, ever larger and nicer beach homes
and buildings and parking lots in the watershed all have an
impact on the Lakes. As the population grows and the suburban
lifestyle keeps spreading, the health of the lakes is compromised
in countless tiny ways. Reporter Peter Payette finds those tiny

We’re continuing our look at ‘Ten Threats to the Great Lakes.’
Lester Graham is our guide through the series. He says the
experts who were surveyed to determine the threats say rapid
development is among the problems affecting the lakes:


One of the more subtle but relentless threats to the Great Lakes is
coastal development. Condos, ever larger and nicer beach homes
and buildings and parking lots in the watershed all have an
impact on the Lakes. As the population grows and the suburban
lifestyle keeps spreading, the health of the lakes is compromised
in countless tiny ways. Reporter Peter Payette finds those tiny
ways all add up:


Greg Reisig is standing at the edge of a 20-acre construction site
just down the street from the shore Lake Michigan.


Below him is a man-made pond a few hundred feet long. It was a
dry summer around here, but the pond is full.


In fact, Reisig says the water level is always the same.


“And that indicates there’s a lot of ground water flowing
here…there’s a lot of water in this pond and you can see what
was a whole big wetland complex…there’s a lot of cedar and red
osier dogwood…all the wetland plants.”


There are no wetlands here now.


The site in northern Michigan was excavated for homes a few
years ago.


But now the Army Corps of Engineers says the wetlands that
were here need to be restored. A few acres likely will be
restored. But Reisig says almost the whole site was wetlands
once. He expects it will soon be a subdivision with not much
more than a drainage ditch connecting it to Lake Michigan.


“What will that do to the amount of flow of water going into the
bay? Because of hard road surfaces, hard driveways, roofs,
buildings and supposedly fertilized lawns. What will happen to
the water and how will that increase the flow to the bay?”


The developer’s attorney says this is nonsense. Matt Vermetten
says this land was heavily farmed and mined for clay.


“There are pockets of quote unquote wetland and those are there
because of excavation for clay. So is this a wetland complex of
the nature we speak of when we typically speak of such a thing? I
think not.”


Disputes like this are becoming more common around the Great
Lakes. John Nelson is the baykeeper with the Grand Traverse
Bay Watershed Center. The bay off Lake Michigan and attracts a
lot of people. But Nelson says development doesn’t have to be a
problem.


He says the problem is people don’t think about the ecology of
the lakes. For example, east of Traverse City, Michigan, resorts
dominate the coastline. Along the beach, thick stands of sedges
and rushes extend out a few hundred feet. But the sections of
dark green marsh alternate with stretches of clean sand and white
lawn chairs.


(birds calling on beach)


Nelson grew up here and says this part of the lake was never a
sugar sand beach.


“They’ve located in a coastal marsh. Instead of celebrating and
dealing with that they’ve chosen to see it as they would like to
have it and then change it.”


The impacts of the changes are cumulative. Fish and wildlife
habitat is fragmented. The natural filtering properties of the
wetlands are gone.


So every time the city gets a rain shower all the dust and grime
and pollution are washed right into the lake.


Census data show people are leaving many of the Great Lakes
coastal cities and spreading out along the coastline. But it’s not
clear how local governments should plan for the growth.


Mike Klepinger studies land use planning for the Michigan Sea
Grant program. He says it’s hard to make direct connections
between a healthy lake and particular land uses.


“We are getting more planning along the shoreline than we had
thirty years ago in the state. The number of counties and number
of townships that have a plan has gone up, for example. But we
don’t know whether those plans are really doing any good.”


And it’s hard to implement good planning on a broad basis. In
any area, dozens of different local governments might have
independent control over development.


Multiply that by the number cities, townships and counties along
the coasts of the Great Lakes… and it’s hard to see how it all can
be managed so that enough coastline habitat is preserved.

Development Triples in National Forests

One of the most comprehensive studies of development in and around national forests spells out the size of some potential threats. The Great Lakes Radio Consortium’s Chuck Quirmbach reports:

Transcript

One of the most comprehensive studies of development in and around national
forests spells out the size of some potential threats. The Great Lakes Radio
Consortium’s Chuck Quirmbach reports:


The study by the University of Wisconsin-Madison looked at a half century of
government census data on national forests. The results show the number of
housing units within national forest boundaries tripled between the years 1950
and 2000. There’s also been a big increase in development within a 30 mile
radius of the forests.


Researcher Volker Radeloff says development has brought in more invasive
species… and narrowed the wildlife corridors between forests. He says he realizes
many communities want to grow.


“The danger is if it’s not occurring in a consensus driven or planning process then the
decisions will be made for these communities… and what that means is increasing isolation of
these forests and strong environmental effects.”


Radeloff says in the Great Lakes region, much of the development in and around national forests
is from people building second homes or recreational housing.

Report Projects Future Water Demands

Water use in six Great Lakes states is likely to go up. That’s according to
a news study by researchers at Southern Illinois University. They say, by
the year 2025, demand could outstrip supply in some areas. The Great Lakes
Radio Consortium’s Shawn Allee has more:


The report predicts that in twenty years, the region will use roughly seven
percent more water than it does today. That’s not enough to endanger the Great Lakes or most groundwater sources, but it is enough to strain water resources in some parts of the region.


Water use will grow fastest in Illinois and Ohio, mostly because they are
likely to see the most economic growth. Researcher Ben Dziegielewski says there’s a connection
between wealth and water.


“People with higher income tend to use more water, because they tend to have
swimming pools, and sprinklers for flower beds, and maybe even green lawns.”


The report predicts that states with slower economic growth, like Indiana
and Michigan, will use less water in the next two decades. Wisconsin and Minnesota are expected to use about the same amount of water.

Will New Auto Technologies Lead to Job Losses?

A new report says new automotive technology such as
gasoline-electric hybrid engines could cost thousands of American
jobs. Researchers say states with large numbers of autoworkers
could be hurt the most. We have more from the Great Lakes Radio
Consortium’s Michael Leland:


Sales of gasoline-electric hybrids amounted to less than one-percent of all
the vehicles sold in the U.S. last year. But researchers at the University
of Michigan’s Transportation Research Institute say hybrids, and vehicles
made with advanced diesel powertrains, could make up eleven percent of total
sales by 2009.


If that happens, the Institute projects it could cost the
U.S. about 200-thousand jobs. Pat Hammett directed the study. He says that
figure includes both actual jobs lost and new jobs not created.


“A lot of the hybrid components, for example, actually are new componentry
inside a vehicle. So, it isn’t necessarily that you are losing jobs in some
of that area, it could just be an example of not getting the growth.”


Hammett says auto-producing states like Michigan, Ohio and Indiana would be
affected more than others. The report says states could reduce jobs lost to
new technologies by offering tax credits to encourage production in the
United States.

Outdoor Lab Forecasts Global Warming Effects

Scientists from around the world are studying how higher levels of carbon dioxide will affect forests 100 years from now. They’re doing that by pumping higher levels of CO2 and ozone into stands of trees. The Great Lakes Radio Consortium’s Mike Simonson visited the experimental forests and has this story:

Scientists from around the world are studying how higher levels of carbon dioxide will affect forests 100 years from now. They’re doing that by pumping higher levels of CO2 and ozone into stands of trees. The Great Lakes Radio Consortium’s Mike Simonson visited the experimental forests and has this story:


(sound of “quiet area”)


The north woods of the Great Lakes states are stands of millions of acres of pine, maple, birch, and aspen forests. It’s a perfect place to try to figure out how trees will react to the higher levels of ozone and carbon dioxide scientists expect in the future.


(sound of beeping fence gate)


The first thing you notice at Aspen Free Air Carbon Dioxide Enrichment Project – Aspen FACE for short – is two huge tanks inside the fenced in enclosure. Each one is bigger than an 18-wheel tanker truck. They’re full of carbon dioxide… CO2. So much CO2 is used in this experiment, the tanks are filled twice a day.


(sound of filling tanks)


If you looked at the site from an airplane, you’d see 12 circular tree stands surrounded by 30 foot high pipes. Those pipes pour CO2 or ozone gases or both into the air surrounding birch, sugar maple, and aspen trees. The scientists know that greenhouse gases in the earth’s atmosphere have been increasing. They believe two centuries of industrial pollution has contributed to the problem. And they expect the CO2 and ozone levels to double by the end of this century. They’re raising the level of greenhouse gasses in different mixes to see what the predicted levels will do to forests.


This open air project is different than previous experiments. David Karnosky is with Michigan Tech. He’s the Project Manager for Aspen FACE. He says before these kinds of projects, they just tested trees inside places like greenhouses.


“We needed to get out of those chambers. We needed to have a more realistic, real world sort of situation where we had multiple trees. We wanted real intact forest communities. We didn’t want to have just a small number of trees inside of a chamber.”


The United States Department of Energy launched this experiment in Wisconsin’s northwoods seven years ago. Karnosky says they’re learning how the trees react to the higher CO2 levels, and that could shape the future of the world’s timber industry.


“Who will be the winners? Who will be the losers? Will aspen or birch or sugar maple? In northern Wisconsin here we’ve got probably 40 million acres of those species mixes. What’s going to happen under elevated CO2 in the next 100 years? Will these forests remain as they are?”


(sound of driving on gravel)


Driving to one of the experimental circles, we pull up to a ring of trees. Mark Kubiske is one of the two full-time on-site researchers.


“Now this particular ring is an elevated CO2 plot. CO2 is delivered through this copper pipe. It runs to that fan, there’s a large fan right on the end of that gray building.”


The scientists have found that trees in the CO2 circles grow 30 percent faster than trees without the gas.


“The trees are larger in diameter, they’re straight, they have lots of leaf area, they just look very healthy. That is just in tremendous contrast to the ozone ring. We’ll go up around the corner and look at one.”


Nearby another circle of trees is not doing nearly as well. The trees are skinny, twisted not as tall as the other sites. Higher ozone levels are hurting the trees.


At the sites where pipes emit both ozone and CO2, the tree growth seems normal – except for some stunted maple trees. The leaves of the aspen and birch take in much of the CO2, convert it to sugar which goes to its roots, eventually becoming a natural part of the soil. That suggests forests may help alleviate gases that cause global warming. The Project Director, David Karnosky says CO2 and ozone appear to cancel each other out. But he says it’s too early to draw any firm conclusions. Ultimately, he says governments will be able to look at this glimpse into the future and try to come up with emissions policies that help.


“The whole issue of the Kyoto protocol, our government not signing off on that. There’s been some relaxing of the feelings from what I’ve seen from the President’s report now that they’re beginning to realize that elevated CO2 is having an impact on global warming and could be impacting our plant communities.”


Karnosky says it’s possible that besides reducing emissions, governments might determine that planting more trees might be very helpful in reducing greenhouse gasses worldwide.

Major Dock Corrosion Stumps Officials

  • The Duluth Seaway Port Authority's bulk cargo dock is typical of many in the port. Officials are troubled by corrosion appearing on the docks in the harbor - the steel is corroding much faster than normal. (Photo by Bob Kelleher)

Corrosion is eating away at the steel walls that hold one of the Great Lakes’ busiest harbors together. The corrosion is unlike anything known to be happening in any other Great Lakes port.

Corrosion is eating away at the steel walls that hold
one of the Great Lakes’ busy harbors together. The
corrosion is unlike anything known to be happening in
any other Great Lakes port. But other port officials
are being encouraged to take a closer look at their own
underwater steel. The Great Lakes Radio Consortium’s
Bob Kelleher reports:


Some kind of corrosion is eating away at the Duluth
Seaway port’s docks. The docks are those long
earth-filled metal rectangles where ships from around
the world tie up to load and unload. Those docks are
lined with sheets of steel, and the steel is rusting
away. Jim Sharrow is the Duluth
Seaway Port Authorities Facilities Manager.


“It’s corroding quickly – much faster than people expect
in fresh water. And our main concern is that we’ll lose
the integrity and the strength of the dock long before
expected, and have to do steel replacement at $1,500 or
more per lineal foot, much earlier than ever would have
been expected.”


Corrosion should be a slow process in Duluth’s cold
fresh water. But, Sharrow says, there’s evidence it’s
been happening remarkably quickly for about thirty years.


“What we seem to see here is corrosion that started in
the mid 1970s. We have steel that’s 100 years olds
that’s about as similarly corroded to steel that is 25
to 30 years old.”


It’s a big problem. There’s about thirteen miles of
steel walls lining docks in the harbor that serves
Duluth, Minnesota and Superior, Wisconsin. There’s half
again as many feet of wooden docks, held together with
steel pins. There’s corrosion on the legs of highway
bridges and the giant
steel ore docks that ship millions of tons of taconite
– a type of iron shipped to steel mills in Gary,
Indiana and Cleveland, Ohio.


“We characterize this as a 100-million dollar problem in
the harbor. It’s a huge problem, and what is so odd
about this is that we only see it happening in the
navigational area of the Duluth-Superior Harbor.”


The harbor links the St Louis River with Lake Superior.
Go a few miles up the river and there’s little corrosion
. So it doesn’t seem like the problem’s there. But, back
in the harbor, at the current rate of corrosion, Sharrow
says, the steel will fail quickly.


“I figure that in about 10 years at the current rate,
we will have to start replacing steel.”


“Particularly marginal operators could decide rather
than repair their docks it would be better for them to
go out of business, and we’re hoping that that isn’t
the case here.”


While the cause is a mystery, there’s no shortage of
theories. It could have something to do with stray
electrical voltage; water acidity; or the kinds of
steel manufactured in recent years. Chad Scott
discovered the corrosion in the late 1990’s. He’s an
engineer and a diver. Scott suspects
a micro-biological connection. He says there might be
something growing in small round pits that form on the
steel.


“We cleaned up the water. That’s the main thing –
that’s one of the main changes that’s happened since
the 70s, is we’ve cleaned up our water. We’ve cleaned
up our harbor, which is a good thing. But, when we
cleaned things up we also induced more dissolved oxygen
and more sunlight can penetrate the water, which tends
to usually promote more growth – more marine
microbiology growth.”


A team of experts met in Duluth in September to share
ideas. They came from the U.S. Navy, The Army Corp of
Engineers, and Ohio State University. And they agreed
there’s something odd going on – possibly related to
microbes or water chemistry. They also recommend that
other Great Lakes ports take a closer look at their
underwater steel. Scott says they at least helped
narrow the focus.


“We have a large laundry list right now. We want to
narrow that down and try to decide what is the real
cause of this corrosion. And these experts, hopefully,
will be able to get us going on the right direction,
so we can start doing testing that will identify the
problem.”


With the experts recommendations in hand, port
officials are now planning a formal study. If they
do figure out the cause, then they’ve got to figure
out how to prevent it. They’re in a race with
something, and right now they don’t even know with
what.

Clear-Cut Demonstration Angers Forest’s Neighbors

Most forests in the Great Lakes region are privately owned. That concerns the U.S. Forest Service because the agency says many forest owners don’t know how to properly manage their woodlands.

Most forests in the Great Lakes region are privately owned. That concerns the U.S.
Forest Service because the agency says many forest owners don’t know how to properly
manage their woodlands. The Great Lakes Radio Consortium’s Julie Grant reports that a
new education project that demonstrates tree-harvesting techniques has angered some residents:


(sound of chain saws)


Workers are cutting down trees in a fifty-year-old pine crop. At the same time, state
foresters are leading a botanist, a private tree farmer, and a reporter through this forest
education site. One of the foresters, Rick Miller, is directing the chain saws to show what
needs to be cut for what’s called a “crop tree release.”


“This one here we selected out with the orange flags, the trees that show the best form and
dominance in the crown. They have a nice big healthy crown. And then what we’re doing is removing
any trees that are touching the crowns of those ones that are orange, and just opening it up
to give the crown more room up there to spread out and possibly increase their growth and their
vigor.”


A forest owner who wants to make money off his pine stand might do a crop tree release to
improve the quality of the remaining timber. The bigger the tree, the more money it’s worth
to a logging company.


Heading deeper in, a crop of pine trees lined up like soldiers trails to our right, and wilder
hardwoods shade us from the left. There are signs to demarcate different timbering techniques:
improvement cut, understory removal, selective cut. Project manager Frank Corona stops at one
section of oaks, maples and cherries.


“You have small trees, medium trees, some larger trees. Trees are probably selectively
harvested in here and you have all different ages of trees in this stand…”


The cool shaded path abruptly opens up. The lush canopy is replaced by harsh sunlight.


GRANT: “Oh wow, so this is the clear-cut…”


CORONA: “This is the clear-cut.”


The forest is gone… cut to the ground. All that remains are the 120 hardwood stumps on
the torn-up dirt. Botanist Steve McKee suports construction of the demonstration site.
But he also loves trees.


GRANT: “What do you think when you see that clear-cut?”


MCKEE: “Well, clear-cuts are never pretty, ya know? So, uh, I think the most shocking thing
for me is I’ve walked in this my whole life and it was surprising. But I knew it
was coming too, so…”


But some people in the community say they didn’t know the demonstration project would include
clear-cutting older trees. Anne McCormack hikes the Mohican nearly every day, clearing trails,
cleaning garbage, or enjoying the woods. The education site has been roped off from the public
during construction. But she found out there was a clear-cut demonstration in an old growth
section of the forest.


“So, I just was… I was just shocked. I mean I can’t say anything more. I just felt
terrible for… I felt terrible for the trees that stood there since before white settlers
were even in Mohican. And there they just were bulldozed and chain cut for education.
I mean, it doesn’t add up.”


McCormack’s not the only one who’s upset. A lot of people didn’t realize this is what
the Forest Service had in mind. Back at the clear-cut site, Corona says many trees suffer
from disease when they mature to 120 years. He says it’s a good age for private land owners
to consider the clear-cut option.


“This was a time where before they would rot out or anything and we see more damage, more
susceptibility health-wise in the entire stand, we could make a harvest in here and utilize
those trees and start this whole new cycle of growth in here.”


The foresters and forest owners say clear-cutting is a viable option, and just one of the
many examples at the demonstration project in the Mohican forest.


Tree farmer Scott Galloway says people need to understand that owning a forest is another
form of family farming. For instance, he got a call recently from a man who inherited 30
acres and needed money right away. He doesn’t know how to manage his tree crop.


“Where does he go? How do you make the right decisions quickly? The faster he can make
decisions, in his lifetime with his forest, the sooner he’ll be able to enjoy the benefits
of those decisions. It’s all about forestry, wildlife, natural resources. So the more education he
can get, the better those decisions will be and the better off all of us are environmentally because of it.”


The Forest Service says a demonstration project is needed because forest acreage is getting
cut up into smaller and smaller parcels. That means the forests are owned by more and more
people who need to know how to manage their timber. The Forest Service hopes this project
will help them make better decisions.

Utilities Obstructed in Long-Term Planning Efforts

Municipal water and sewer plants are gathering better data on how their systems are used for
better planning, but a government report finds that short-sighted local governments sometimes
end up derailing the utilities’ long-term plans. The Great Lakes Radio Consortium’s Lester
Graham reports:


A lot of federal money is used to build local drinking water and wastewater facilities. So, the
Congress asked its investigative arm, the General Accounting Office, to see if the money is used
wisely. The GAO found that many municipal utilities are using comprehensive asset
management for planning purposes. That’s closely looking how systems are used, where the
demand is growing, and how best to plan for future growth.


But the utilities are running into some problems. Collecting and managing all of that data is a bit
overwhelming. The GAO recommends the Environmental Protection Agency help municipalities
share data on an EPA website so that every utility is not gathering the same kind of information
over and over.


There’s still one more problem. Even with better information, the GAO found… often the local
politicians who oversee the utilities have short-term goals that hamper long-term planning by the
utilities.

Study: Invasive Plants Lack Microbial Controls

New research indicates that some invasive plants spread rapidly because they
don’t have natural enemies to keep them in check. The Great Lakes Radio
Consortium’s Mark Brush explains:


The research found that some foreign plants thrive in North America because
they’ve escaped their natural enemies. In a study published in the journal
Nature, researchers found some of the enemies the plants escaped were
in the soil. They looked at the invasive plant spotted knapweed. They found the
plants are not only free from microbes that might eat their roots, but they
also found microbes in the areas the plants invaded that actually help them
grow.


Ray Callaway is one of the researchers at the University of Montana.
He says regulations are needed to stop these kinds of invasions:


“I think we ought to have much stronger restrictions on the movement of
horticultural plants and so on from across continents. I think we’re
playing with fire.”


The majority of plant invasions come from the horticultural trade. Policymakers are now
working on a protocol to monitor the importation and sale of non-native plants.
