DNR launches new prevention efforts in 2012 to slow spread of
aquatic invasive species
(Released January 6, 2012)
The Minnesota Department of Natural Resources (DNR) announced
today its new strategies to fight the spread of aquatic invasive
species across the state in 2012.
The efforts take a two-pronged approach: to increase inspections
and decontamination of boats at and near water bodies, especially
those infested with aquatic invasive species; and to increase
awareness that the public must do its part not to spread invasive
species.
“The DNR cannot be at every boat ramp this summer, making sure boaters, anglers and other water users are not bringing zebra mussels and other invasive species to public waters,” said DNR Commissioner Tom Landwehr. “Our message is these waters belong to everyone – so everyone needs to be responsible for not moving these invaders.

The Myths and Hysteria surrounding Zebra
Mussels
By Jeff Peltier
There is a lot of Hysteria floating around regarding Zebra Mussels and the damage they can cause, so let’s review some of the concerns.
Zebra
mussels will destroy docks and lifts.
While they will attach to objects and as they become more populated even plants and other clams or shells, they do not eat metal or plastic. We are fortunate that in our climate the lakes freeze over and people take their docks and lifts out. The Zebra mussels die when out of the water or at temperatures below freezing. If you would like to remove them from your lifts and docks and want to do it at a minimum effort, I would wait until spring after the mussels are dead and have freeze-dried a few times. It’s much easier than trying to remove them right after removal from the water. Continued

HELP PREVENT THE SPREAD OF ZEBRA MUSSELS FROM PELICAN TO OTHER AREA LAKES
Zebra
mussels were found in Pelican Lake in September, 2009.
Zebra mussels are an invasive species that has been spread
throughout Minnesota Lakes , including Mille Lacs and the Alexandria
area lakes. Zebra mussels are ¼ to 1 ½ inches long and are
D-shaped with alternating black and brown stripes. Zebra mussels are
tricky to find when they are larvae, because they are not visible to
the naked eye. The larvae can live in your live well if there is
water there, or in your minnow bucket and then spread into other
lakes. Zebra mussels can attach to hard surfaces such as boat
lifts and docks and clog water intake pipes.
At this time there is no treatment for zebra mussels; however, research projects are in progress and we are hopeful that in the future a treatment will be available. Until then, it is imperative to prevent spread to other lakes so that the problem remains contained.
AVOID THE SPREAD
Please take the following steps to prevent the transport of zebra
mussels and other aquatic invasive species to new waters:
·
Inspect
and remove aquatic plants, animals, and mud from your boat,
trailer, and equipment.
·
Drain
all water from your motor, livewell, bilge, transom, etc.
·
Dispose
of unused bait in the trash.
·
Wash
your boat and equipment with hot and/or high pressure water,
particularly if moored for more than one day, OR
·
Dry
your boat and equipment thoroughly (in the sun) for five days.
PROTECT YOUR BOAT
Is your boat protected against zebra mussels?
Unfortunately, some boat
owners are seeing and feeling the damage caused by zebra mussels
first hand. Their boat hulls
are being damaged and their motors are overheating because they do
not know how to minimize the impacts zebra mussels can cause.
-
Use a boatlift to completely remove the watercraft from the
water.
-
Use your boat (run the engine) at least twice a week at slow
speeds (4 mph) for 10-15 minutes.
The hot water will kill the zebra mussels in your
engine’s cooling systems.
-
Lift motor out of the water between uses if mooring.
-
Tip down the motor and discharge the water when leaving a water
body.
-
Rinse your boat and equipment if you leave Pelican Lake and
intend to visit another lake.
- Apply antifouling paints to the hull and the engine’s cooling system. In-line strainers can also be installed in some cooling systems.
- Apply protective paint to your boat’s hull. (See below)
Bottom Paints that work in Fresh water
For those trying to protect aluminum boats, lifts, docks, etc from
Zebra Mussels, note that it is important to know which paints can be
used. Here are some
guide lines.
Aluminum hulls, outdrives and props require paints such as
Vivid, Trilux 33,
Trilux Prop and Drive Paint
and Alumaspray that
do not contain cuprous oxide,
which reacts destructively with the aluminum. Copper-based paints
are safe for use on properly primed stainless and bronze. Zinc
anodes should be left unpainted to retain their effectiveness.
For fiberglass boats, there is a different selection of paints that
do well in fresh water
Pettit Super Premium,
Pettit Hydrocoat and
Interlux Ultra are high
in copper and quite effective. Slick
racing paints like Pettit
SR-21 and Interlux VC-17M
are lower in copper, but still hold up well in Lake Erie.
Interlux
Bottomkote Aqua is a good
water-based hard paint
2010 Access Inspection report is now in
It took a little longer to get the report from
the DNR this year, but the information is now in.
There were 1483 inspections done over a period of 746 hours.
Even though there were more hours at the east access than the west
access, more boats were inspected at the west access which would
indicate that access is more active. About half the boats inspected
were out of state with the vast majority being ND.

New Regulations on transport of water
As of July 1, 2010, the following regulations, apply to the
transportation of water by boaters from all waters in the state
(violations are misdemeanors):
-
a person leaving waters of the state must drain boating-related
equipment holding water and live wells and bilges by removing
the drain plug before transporting the watercraft and associated
equipment on public roads; and
-
drain plugs, bailers, valves, or other devices used to control
the draining of water from ballast tanks, bilges, and live wells
must be removed or opened while transporting watercraft on a
public road (marine sanitary systems and portable bait
containers are excluded from this requirement).
Forest Tent Caterpillar Alert 5/29/10
We
are seeing an outbreak of Forest Tent Caterpillars (FTC) around the
lake. They are not on every beach, but in numerous spots
around the lake and not as thick as on neighboring Cormorant Lake.
At this point, the threshold is not high enough to justify an aerial
spraying of the lake and also the weekly insecticide application for
mosquitoes that just started this Thursday has some control of
FTC. For individuals that are concerned and would like to
spray their own trees and vegetation (especially new tree
plantings), Permethrin and Malathion are a couple of labeled
chemicals with Permethrin being the most safe for people and pets.

Zebra
Mussels
We regret to inform you that
zebra mussels have been found in Pelican Lake . This was confirmed
Monday, September 14 by the Department of Natural Resources (DNR).
Zebra mussels are an invasive
species that has been spread throughout Minnesota Lakes , including
Mille Lacs and the Alexandria area lakes. Zebra mussels are ¼
to 1 ½ inches long and are D-shaped with alternating black and brown
stripes. Zebra mussels are tricky to find when they are larvae,
because they are not visible to the naked eye. The larvae can
live in your live well if there is water there, and then spread into
other lakes. This could be how they entered Pelican Lake .
Zebra mussels can attach to hard surfaces such as boat lifts and
docks and clog water intake pipes.
Please
help us in looking for zebra mussels as you remove your dock and
boat lift for the winter. Contact
Moriya Rufer, PGOLID Water
Resource Coordinator, 218-846-1465, if you find any stuck to your dock and
lift so she can track them on a map of the lake. We want to
monitor their spread throughout the lake. You can see a photo
of zebra mussels below.
Unfortunately, there is no
remedy for Zebra mussels. There is no chemical treatment available
to control them. The best we can do is monitor their spread.
There are some new regulations
that apply to Pelican Lake now that it contains zebra mussels (http://www.dnr.state.mn.us/eco/invasives/laws.html):
-
taking wild animals (fish, frogs, crayfish,
etc.) from infested waters for bait or aquatic farms is
prohibited;
-
equipment used for commercial fishing purposes
in infested waters must be dried or frozen before it can be used
in noninfested waters (misdemeanor);
-
water from infested waters may not be used to
transport fish except by permit;
-
persons leaving infested waters that contain
populations of spiny waterflea or zebra mussels must drain bait
containers, other boating-related equipment (excluding marine
sanitary systems) that holds water, and livewells and bilges by
removing the drain plug before transporting the watercraft and
associated equipment on public roads ($50 civil penalty or
misdemeanor);
-
water from infested waters may not be
transported on a public road or off riparian property on
infested waters except in emergencies or under permit ($200
civil penalty or misdemeanor).
More detailed information will
follow as we learn more about the infestation.

Aquatic plant removal may require permits
- 05/29/2009
Lakeshore property owners are reminded that many aquatic plant management activities require a permit from the Department of Natural Resources (DNR).
Lakeshore property owners can control a modest area of aquatic plants for swimming or boat docking without a permit from the DNR. Cutting, pulling, raking, or harvesting submersed vegetation, like pondweeds, watermilfoil, or coontail, in an area for recreation is allowed under the following conditions:
• The cleared area may not exceed 2,500 square feet in size.
• The cleared area may not extend more than 50 feet along your shore, or more than one half your frontage width, whichever is less.
• If the cleared area does not reach open water, a 15-foot wide channel to open water may be added.
• The cut or pulled vegetation must be removed from the water. If floating leaf vegetation, like white or yellow water-lilies interfere with boat access a lake shore property owner can mechanically maintain a channel no more than 15 feet wide, extending to open water without a permit, under the following conditions:
• The cleared channel must remain in the same place from year to year.
• And the vegetation that is cut or pulled must be removed from the water.
A DNR aquatic plant management permit is required if your plans include the following:
• Using herbicides or algicides.
• Removing emergent vegetation, like bulrush, cattails or wild rice.
• Installing or operating an automated plant control device.
• Removing floating leaf vegetation, in an area larger than a 15 foot wide channel.
• Controlling submerged vegetation in an area larger than 2,500 square feet or wider than 50 feet. • Removing or relocating a bog of any size.
The DNR aquatic plant management regulations do not allow the following activities:
• Excavating the lake bottom for aquatic plant control.
• Use of hydraulic jets.
• Using lake-bottom barriers to destroy or prevent the growth of aquatic plants.
• Removing aquatic vegetation within posted fish-spawning areas.
• Removing aquatic plants from an undeveloped shoreline.
For 2009, Clarke Mosquito will offer extra services for those that
would like to supplement
the weekly Mosquito program provided by PGOLID
Barrier Control Spray:
We apply a permethrin-based product that mimics the properties of
the naturally occurring insecticide produced by the chrysanthemum
plant to all areas of your yard that the mosquitoes harbor.
This kills mosquitoes that come in contact with the treated
areas several days to two weeks on average, depending on the amount
of vegetation in your yard.
It also repels the mosquitoes.
We aim for a noticeable reduction in the mosquito population,
and some people even say they see no mosquitoes at all with our
summer-long programs.
Granular Control:
We apply a granular permethrin-based product to all areas of
your yard or where your special event will occur.
This increases the effectiveness of the barrier spray by
adding to the repellency effect.
We especially recommend this option for areas that have
sparse vegetation, and for any special event.
Pelican Lake Dam update
PGOLID
has been working with the DNR to have the Pelican Lake Dam repaired.
See the attached pictures for a better understanding of the
problem. This has been a
very slow process and the timeline goes something like this.
In the summer of 2003, the center island of the dam washed out and the water level of Pelican Lake started to drop quite rapidly. In the fall of 2003, a steel plate was placed in the washout with rocks and sand filled in front of it as a temporary repair. It was determined at that point, that the DNR controlled the dam and was responsible for any repairs. In 2005, PGOLID started pressing the issue of repairing the dam with the DNR and in the Fall of 2007, it appeared the DNR was going to do the actual repairs to the dam. Unfortunately, the DNR thought a repair meant throwing a few bags of Quikrete in front of the temporary repair which is what they did in the winter of 2007/2008.
In
2008, more meetings with the DNR occurred and a consensus was
reached, that the dam should be repaired before it washes out again,
as the cost would be much higher if the dam washed out before
repairs could be executed.
Paul Diederich of Industrial Builders provided a budget bid
of $250,000 to make those repairs.
It was then learned that 3 years earlier, the DNR also
received a budget bid for the repairs of $200,000.
In the Fall of 2008, conversations with theDNR State director
of the Waters Division revealed the budget for repairing
dams for 2008 was $2M. There were 100 dams on that list though the
Pelican Lake dam not is not currently on the top 20 list.
The New London Dam is #1 at $2M and Brunson State Park is #2
at $8M which adds up to not-enough-money.
More conversations with DNR and our state representatives
concluded that some sort of cost sharing between the DNR and PGOILD
may
be the only alternative to accomplishing the repairs. Talks are
continuing along those lines.
This is clearly a slow process with steps forward and
steps backward.
At this point it’s unclear where it will all end up, but as more progress is made, updates will be available. If you have questions, contact Jeff Peltier
as he has been taking the lead in this process.Weed Rollers require a DNR permit
It’s been reported that the DNR went around Pelican Lake and found about 20 Weed Rollers or similar type equipment that didn’t have proper permits. The fine they issue for that is $250 and the permit costs $35, so it makes sense to get a permit first. You can download the permit here: http://files.dnr.state.mn.us/assistance/backyard/shorelandmgmt/apg/apmapp.pdf
E-coli alert for Bob Creek
PGOLID has done some rain event sampling of the water at Bob Creek as it enters the west end of Pelican Lake this summer. This has been a concern because high levels of E-coli bacteria have been found there in the past. During these events the level has been found to consistently be above the standard of 126 MPN/100ml which the state of Minnesota considers not safe for swimming. To minimize any risk, it is suggested that you have your children or grandchildren avoid playing in or adjacent to the creek for a 24 hour period after a rain event until a remedy can be put in place to improve the situation.
PGOLID monitors
Flowering Rush
This in an invasive aquatic plant that is currently in Detroit Lakes, Lake Sally, and Melissa, but stops at Buck’s Mill. PGOLID is working with the Pelican River Water Shed and the DNR on a program to reduce or eliminate Flowering Rush along with regular trips down the river to monitor the situation. Click HERE for a description of the plant.
Safe Ice recommendations
The DNR recommends 4 inches for ice fishing, 5 inches for a snowmobile or ATV, 8 to 12 inches for a car or small pickup, and 12 to 15 inches for a medium truck. Considering the recent conditions, ice that may be thick enough might not be of high enough quality to hold.
PGOLID Lake Management Plan is now on the web!
The PGOLID Lake Management Plan is a comprehensive
report from over a decade of data collection and effort from many
organizations. It is a summary of water quality data along with
information and background about the surrounding area, demographics
and land use. Moriya
Rufer, our Water Resource Coordinator, has done an excellent job of
organizing this into easy to navigate segments so you can quickly
find particular items of interest. Go to

Buckthorn is designated as a restricted noxious weed in Minnesota

The Shoreline Habitat Restoration Grant program is to help with shoreline restoration, specifically to: restore native shoreline vegetation across the state, expand the diversity and abundance of native aquatic and shoreline plants; improve and protect the quality of shoreline habitat; enhance and protect water quality; raise awareness of the value of native shoreline and aquatic vegetation.
While there, Linda became aware of Buckthorn growing on this property and the neighbors. The buckthorn is designated as a restricted noxious weed in Minnesota. Fall is the easiest time to identify buckthorn. The leaves of buckthorns do not change color until late in the fall, after most other trees have changed. The berries usually stay on the branches until March and are widely dispersed by birds. Once established, these species aggressively invade natural areas and form dense thickets displacing native species. They leaf out very early in the growing season and keep their leaves late into the fall helping to shade out native trees, shrubs and wildflowers. These branches have numerous thorns. The side branches have short terminal spurs, or thorns, which are literally a pain if you try to remove the plant.
Linda is encouraging PLPOA members to read up on the Buckthorn and do all they can to eradicate this invasive plant. To read more about it and what you can do to remove it please go to:

Take steps now to
protect your septic system from freezing
Common reasons systems freeze are lack of snow cover, cold temps
Low snowfall amounts can mean potential danger for your septic system. For the last few winters, we have had a pattern of sub-zero weather arriving before major snowfall. Remember last winter? We did not get significant snowfall until March.
PGOLID has put together an aquatic plant guide.

There have been a lot of questions about spraying for the Forest Tent Caterpillar.
We are now
past the window for the need to spray this year, but still need to be alert in
the next couple of years as the cycle is not exactly 7 years, but a range of 6
to 10 years. Many of the sightings this year were not the species of
caterpillar we were looking for, so here is picture to help with identification.
Note the white or light colored dots on the back. Also the Forest Tent
Caterpillar does not form spider-like webs like other tent caterpillars.
