Milfoil

We need YOUR  help to fight the spread of Milfoil in Grand Lake

Eurasian Milfoil is an invasive aquatic plant native to Europe, Asia and northern Africa. Introduced to North American the 19th century, it is now one of the most widely distributed invasive aquatic plants on the continent.

Outside its native range, the plant has spread across every continent except Antarctica.

A  report prepared by the Federation des Lacs de Val-des-Monts in conjunction with the Municipality first reported Eurasian Milfoil in Grand Lake in 2014.

What is the Grand Lake Association doing to fight milfoil? The fight against Eurasian Milfoil, as with any invasive species, will be ongoing. It’s only through the cooperation of all cottagers, and the help of many volunteers that this scourge will be kept under control.

The Grand Lake Association, in partnership with federal, provincial, and local governments, is working to monitor and mitigate the impacts of Milfoil on our lake.  A new report by Stéphanie Milot of the Féderation des lacs de Val-des-Monts shows the areas of Grand Lake with the largest Milfoil infestations.  New yellow buoys will be installed in these areas in the spring of 2021

To keep the spread under control, we urge all cottagers (& visitors to our lake) to please, follow these rules:

  • When coming from another lake or river, clean your boat, kayak, canoe – any watercraft!
  • Check your motor after and during each use to ensure no Milfoil has been caught up.
  • Follow the recommended speed limits in our directory to avoid churning up the Milfoil.
  • Pick up any pieces you can & keep the area around your property as free as possible. Be vigilant!
  • Dispose of milfoil in your garbage.
  • Do not let it dry out – a dead plant can blow away, take root again, and grow. That’s why Milfoil is often called the “zombie plant”.

  • Keep away from the areas marked with the White Milfoil warning buoys and the new yellow warning buoys. No swimming, or watercraft in these areas please!
  • Refer to the milfoil on the map in your Grand Lake Directory, and on the website, and plan your boating or other recreational activities to avoid these areas.
  • Remember: disturbing the plant can break it and allow it to spread.

Most importantly, your Association is here to help us all keep the spread of Milfoil under control.  There is no magic cure, so please stay vigilant and let the executive know if you have any concerns or suggestions to help stop the spread of this invasive species in our lake.

ABV Mandate Milfoil

Q&A August 12 2020

Milfoil Marker Map

The Grand Lake Executive want to thank everyone who has responded to our recent email “Priorities of Grand Lake”. Several issues were raised and they will be addressed soon.

In this note, the Milfoil Committee wish to respond to the requests for more information concerning how the Association has determined its approach to the management of the milfoil problem:

1. Background 

The Milfoil Committee presented a request to the Executive in 2018 based on information from:

  1. scientific studies and a 2015 report by ABV-7 (who had been contracted by the Executive and prepared the attached map showing Grand Lake with 300,000 m2 of milfoil)
  2. the Federation of Lakes, as well as
  3. observations of what was done on our neighbour’s (Dam Lake) lake for milfoil education.
 The request was approved and under direction of the Committee, some 80 green buoys were installed in 2019 in those areas that had been mapped out as sensitive by ABV-7 and again in 2018 by Stéphanie Milot (M Env.) and a team from the Federation.

Unfortunately, because someone on our lake complained formally to Transport Canada, we have been ordered to remove all these green buoys by September 15, 2020. The 5 milfoil information buoys we also prepared and installed (with Federation guidance) are within TC regulations. We are now in the process of deciding what our strategy going forward will be for milfoil warnings for sensitive areas, which could include additional information buoys in combination with other cautionary markers that help define sensitive areas to avoid.

For your information, please find attached:
  1. the mandate of ABV-7 as well as the map showing the extent of milfoil in 2015;
  2. the part of the report by the Federation (FDLDVDM Report on Riviere Blanche 2014 – all lakes).  The full report is available on the website of the Federation des Lacs de Val des Monts;
  3. the section on Grand Lake, which shows among other things the milfoil in Grand Lake;
  4. a map prepared by Stéphanie Milot for the Federation in July 2018 and suggesting locations for green buoys.  The Committee did its work based on the expert advice and adjustments were made as practical.

The most recent tour of the lake by Stephanie Milot was done on Wednesday 12th August 2020, when she advised on new locations for buoys and warnings.  We are awaiting her written report.

Prior to Stephanie’s visit, we obtained additional information in writing. This came in an e-mail which is also attached for your information.

The Committee has also been working with Rob Perrin regarding Block-Aid (see Grand Lake Newsletter Fall 2018). Grand Lake is on a list of lakes for government research and funding and we are hoping for approval.

2. Location of buoys 

As stated above, buoys were placed in the locations recommended by Stéphanie Milot, a biologist with the Federation des Lacs de Val-des-Monts.

a. Buoys may appear to be in an area that has no milfoil, because the milfoil grows the most in late August, early September.  It will, however, spread if it is disturbed by the wake of any boat, therefore the buoy was deemed necessary.

b. Buoys remained in place over the winter and do indeed move due to ice.  The Milfoil Committee requested information from cottage owners on this in a bulletin sent out on June 2nd and responded to all those who contacted the Committee.  Some have recently complained about placement. Had that been done in June the Committee would have contacted them and sought to make corrections as required.

3. Spread by motors 

Please refer to the following for information concerning motors:

  1. The attached press release dated 2018 indicates the concern of the Province of Quebec regarding the spread of milfoil by watercraft;
  2. Milfoil Committee Update July 30th;
  3. Stephanie Milot’s reply to our email.

4. Use of burlap 

The attached announcement forwarded by Stephanie Milot, written by Claude Lavoie, University of Laval, describes various methods of control, including burlap.  It is pointed out that it is useful but not very successful in rocky areas, or areas with dead trees, etc.

AbV des 7 also proposed the use of burlap, the product of BlockAid which is still not approved. (see Grand Lake Newsletter October 2018). Attached is follow up from our original request to Block-Aid to be part of their study. Please note that it is illegal to use burlap in the lake, therefore the Lake Association cannot recommend it to cottage owners.

5. Spread of milfoil 

The scientific information is that milfoil is mostly spread by it breaking off. Each small piece can make another plant.  The seeds are not a significant cause of spread.  The plants break as follows: naturally late in the year;  when people try to pull up or rake milfoil and other weeds; when swimmers, kayakers, boaters of any kind enter a patch of milfoil; when there is underwater turbulence caused by motors.  Propeller-induced turbulence disturbs the lake bottom and invites the colonization of Eurasian Water Milfoil.  Propellers also physically chop exposed plants causing fragmentation. The Milfoil Committee has been clear that all kinds of water activity can spread milfoil and requests care be taken by all lake users.

Extra content can be found in the Grand Lake Newsletter fall of 2018 which addresses wake, phosphates, etc.
