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

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.
