Making Boat Washing Mandatory

Aquatic plants and animals can cling to the bottom of
recreational boats. That’s one way invasive species are spread. A couple of hitchhiking zebra mussels, or a plant
caught in the propeller are enough to alter the ecosystem of an
entire lake. One resort region has passed laws requiring boaters
to wash their boats before putting them into their local lakes.

Aquatic plants and animals can cling to the bottom of
recreational boats. That’s one way invasive species are spread. A couple of hitchhiking zebra mussels, or a plant
caught in the propeller are enough to alter the ecosystem of an
entire lake. One resort region has passed laws requiring boaters
to wash their boats before putting them into their local lakes.
But some state officials don’t like the new laws, and that
might make it impossible to enforce them. Linda Stephan
reports:


Little Glen Lake is known for unpredictable winds, and clear
blue waters… at times the lake is turquoise. It sits against
glacial dunes that lead to the eastern coast of Lake Michigan.
Sarah Litch retired here with her husband Mike:


“It was kind of a toss-up between New England and here. Miss
the mountains, but we love the water here. Although there are
so many water issues now. I don’t know.”


Those water issues include foreign invasive plants that could
take over Little Glen Lake:


On a pontoon boat, the Litch’s zig zag across the lake, raking up
aquatic plants at the bottom. If there are any invaders, they
want to find them early.


One of the bad guys they’re looking for is Eurasian water
milfoil. That’s a long, thin plant with feather-like green leaves.
Another invader is Hydrilla. You’ve probably seen it in
aquariums. It’s taken over lakes from California to Indiana, and
on to Maine. Both plants grow very quickly, they choke out native
fish habitat, and form a green carpet on the lake surface:


“And then it can be all – you’re trying to boat in all this tangle
of aquatic plants, or swim. So it just ruins a lake.”


These invaders have likely spread from lake to lake across the
US hitchhiking on boats pulled out of one lake, and headed for
another.


Some states such as Maine and Minnesota now require boaters
to make sure crafts and trailers are free of aquatic nuisances
before they drive down the road with them, possibly
endangering other lakes. And in those states, officials inspect
boats, too.


But other states, such as Pennsylvania and Michigan, have NOT
taken those steps, and Michigan borders four of the five Great
Lakes.


Since the state hasn’t passed laws to prevent boats from moving
invasive species from one lake to another, some local officials
have.


Sarah Litch designed a local law that requires boats to be washed
before going into local inland lakes, and it easily passed in two
adjoining communities. So around here, it’s a 500 dollar fine if
you don’t wash your boat.


Homeowners provide a free wash station at the main point of
entry to Little Glen Lake, a state-owned boat launch, but a few
boaters had refused the voluntary local inspections. That
frustrated Sarah Litch enough to fight for new local laws:


“Just to give people that are working at the boat wash a little more
backup when they have a refusal. So that they can inform the
individual and take their license if they refuse.”


But the local governments might end up in a power struggle
with the state agency that controls the boat launch, the
Michigan Department of Natural Resources. The state
agency doesn’t like this new local law.


Jason Fleming – who’s with the agency – says the homeowners’
boat wash has been successfully running on state property for a
decade, but only because the state allows it with special
permission:


“When we established that with the association, it was based on
a voluntary basis. So we’d have to review the terms and the
language of that agreement.”


In other words, if workers at the wash station start reporting
boaters to the local sheriff for refusing their services. Fleming
says the state might kick them off the state-owned boat launch
property. He says a voluntary approach is enough.


State officials don’t believe the local law applies to the state-
owned boat launch.


Chris Bzdok is an environmental lawyer. He says state courts have repeatedly ruled that local
governments can make laws like this one… and they can enforce them:


“The localities have a right to protect these resources – whether
they’re being accessed through a road end, through a private
marina, or through a state facility. The larger question is why
the DNR has a problem with it. What would be any good-faith,
genuine, substantive reason for opposing that?”


Scanning the lake from the boat launch, Sarah Litch talks of
what to do when – not if – the next invading plant or aquatic
animal arrives.


She says the best way to protect the lakes is to enforce the local
law, to make sure boats don’t bring in new invaders.

Combating Inland Invasives

Invasive plants, fish and other creatures are threatening many inland
lakes. Evironmentalists and property owners are trying to stop the
spread…before the invaders dramatically alter the smaller bodies of
water. The Great Lakes Radio Consortium’s Ann-Elise Henzl reports:


It’s strange to think that plants and animals from Europe, Asia and Africa
are living in small lakes in the Midwest. Boaters have taken invaders
there…after picking them up in the Great Lakes.


The big lakes are home to more than 160 aquatic invasive species,
including Eurasian Watermilfoil. The stringy plant grows in thick
clusters that get up to 12 feet tall.


“I have seen lakes where if you fell out of the boat in these massive
weeds and you weren’t wearing a life jacket, I don’t care how good a
swimmer you are, you would sink. You can not struggle your way
through these thick entanglements of weeds.”


Ted Ritter leads an effort to reduce aquatic invasive species…in
Wisconsin’s Vilas County.

On one afternoon he takes his pontoon boat on a lake that had an
infestation of Eurasian Watermilfoil.


“It is a very aggressive plant and it has no natural predators to control its
growth, it grows up to two inches a day.”


When Eurasian Watermilfoil finds conditions it likes, it takes over
quickly. A piece as small as two inches can break off, and float away to
create a new plant.


Eurasian Watermilfoil is widespread in northern Michigan… northern
Wisconsin and other places. It’s one of dozens of aquatic invasive
species on the move in the region.


One of the worst invaders is zebra mussels. They can ravage a lake’s
ecosystem.


(Sound of motor boat)


So far, they’ve made it to just one lake in northern Wisconsin. Mike
Preul with the Lake Superior Chippewa scuba dives there, to count the
mussels. Three years ago, he found 7 adults per square meter. This year,
he counted more than 14-hundred:


“They’re still increasing. What they’ve seen in other systems is that just
like with any other exotic species they’ll come in, the population will
explode, they’ll kind of eat themselves out of house and home, and then
they’ll come down to a level and reach a steady state.”


No method has been discovered to get rid of zebra mussels, but there are
ways to control some invaders.


Herbicides can be used to kill Eurasian Watermilfoil, and some property
owners chip in to buy aquatic insects to kill the plants.


Les Schramm did that on his local lake:


“As the larvae hatches it burrows into the stem of the Eurasian
Watermilfoil and sort of eats out the center vascular part, and it falls over
and dies.”


People fighting aquatic invasive species say it’s like fighting weeds in a
garden — the work never stops and it can be expensive.


Ted Ritter of Vilas County says it costs thousands of dollars to treat a
lake once. So, often people do nothing.


Ritter says that can hurt the environment. He says it can also threaten the
economy, in areas like northern Wisconsin that rely on tourism.


Ritter says the invaders can reduce the appeal of a lake. He mentions a
plant called “curly leaf pondweed.” When it dies in the middle of
summer, it creates algae blooms that look like slimy green pillows:


“When people arrive at resorts and they look out and they see that very
unappealing lake they say ‘I’m not staying here,’ and they go somewhere
else. When realtors bring prospective buyers out to look at a property,
people get out of their car and they go right to the lake and they say ‘oh
my, I’m not even interested in looking at the house. This lake is
horrible.'”


Because it’s so difficult to control invasive species, Ritter and others
fighting the invaders focus on prevention.


Local volunteers and workers from the Wisconsin Department of Natural
Resources spend hours at boat landings. They urge people to clean their
boats, trailers, and fishing gear thoroughly when going from lake to lake,
that can keep unwanted plants and creatures from traveling along.

Dilemmas for Wastewater Treatment Plants

Municipal sewer plants are sometimes blamed for high E. coli bacteria counts that close beaches to swimmers. Some cities are working to find better ways to treat the water and put it back into nature. The Great Lakes Radio Consortium’s Chris McCarus reports:

Municipal sewer plants are sometimes blamed for high E. coli bacteria counts
that close beaches to swimmers. Some cities are working to find better ways to treat the
water and put it back into nature. The Great Lakes Radio Consortium’s Chris McCarus
reports:


(sound of cars moving along a small street and a few people talking)


A typical summer day by the lake: SUVs pull boats on trailers. People saunter from an
ice cream shop to the city beach. Jet skis and water skiiers slice through the waves.
Carpenters raise trusses on homes being built into the remaining lakefront lots.


Just a few years ago it seemed towns like this were just for loggers and locals. But now
people are flocking to the lakes around the Midwest and staying there. And that’s putting
a strain on local sewer plants.


(sound of machines inside the water treatment plant)


For 40 years, the treated waste water from the Boyne City, Michigan sewer plant has
been released into the big lake it was built on…Lake Charlevoix.


“It’s located right adjacent to a public swimming beach, park, marina and some valuable
waterfront property. We are only a block off the downtown district.”


Plant manager Dan Meads wants to stop mixing the end product with the water where
tourists and the locals swim and play. He tests daily for E. coli bacteria. He
doesn’t want anyone getting sick. But it’s still a concern, and there are other concerns.


In recent years, the United States Geological Survey has reported on new kinds of
contaminants that they’ve found in ground and surface water. The USGS says treated
wastewater from sewer plants can contain hormones from birth control pills, antibiotics,
detergents, fire retardants, and pesticides.


USGS microbiologist Sheridan Haack says the effects of all these compounds are still
unknown. Most are found in tiny quantities, but combined they could cause any number
of chemical reactions.


“There are many different chemical structures and it would be very difficult to state for
all of them what we would actually expect the environmental fate to be and how they
would actually be transported through the environment.”


Haack says the medicines people take don’t disappear. They eventually leave the body
and are flushed down the toilet. Those drugs have been tested for safe human
consumption, but the question is: what happens when those chemicals are mixed in with
industrial waste, accidental spills and nature’s own chemical processes? Haack says they
just might come back around to hurt humans, fish and wildlife.


The Boyne City solution is to build a new wastewater treatment plant two miles from the
beaches up the Boyne River. Officials say contaminants will be diluted by the time they
flow back down into Lake Charlevoix.


(sound of the Boyne River)


Larry Maltby volunteers for a group called “Friends of the Boyne River.” The group
doesn’t like the city’s plan to discharge treated wastewater directly into the river. It wants
them to consider some non-traditional methods. They say the new sewer plant could run
a pipe under a golf course or spray the treated water on farm fields… or let it drain into
wetlands to let nature filter it out.


“It will seep into the soils which are very sandy and gravelly underneath the golf course
and then the filtration through the ground will have a great deal of effect of continuing to
purify that water. Much more so than it would be with a direct deposit, straight into the
surface waters of Michigan.”


Lawyers for the Friends of the Boyne River have appealed to the state dept of
environmental quality and filed a lawsuit.


But wastewater treatment plant manager Dan Meads says the city doesn’t want to please
just one group and end up angering another…


“There isn’t any guarantee that you can satisfy everybody. We think we have the best
option available.”


As municipalities are short on funds and personnel, they don’t want to wait for decades
for the perfect solution. Still, nobody wants any amount of pollution to affect their home
or their recreational area.


Sheridan Haack with the USGS won’t take either side in this dispute. She says not only
are the dangers from contaminants unknown, the best way to deal with them is unknown.


“I am not aware of any consensus in the scientific community on the nature or types of
treatment for this broad range of chemicals.”


In the meantime… communities such as Boyne City have the unenviable task of trying to
dispose of their residents sewage without polluting the beaches, the fishing, and the
environment that brought folks there in the first place.
