Eurasian Watermilfoy - A Problem

What is Eurasian watermilfoil?

Originating in Europe, Eurasian watermilfoil is an invasive aquatic plant that grows at depths of 1 to 4 metres [but may sometimes also be found in water as deep as 10 metres] and forms a dense carpet on the lake’s surface.  According to Environment Canada, “this plant not only pushes out indigenous plant species, but may also be harmful to fish populations by crowding out their spawning grounds… Eurasian watermilfoil is also an impediment to recreational use of aquatic environments.”
 

What are we doing?

In the short time that the Association has been in existence, there have been several positive achievements:

- Permit

  • Official registration of the Association – September 2004
  • Authorization to harvest the milfoil

- Expertise

  • Ongoing expertise, advise and assistance from Paul Hamilton, researcher at the Canadian Museum of Nature
  • Training and development of water testing procedures from biologist Anne Phelps

- Funding

  • Contribution of $6,400 from the Municipality of La Pêche for the purchase of a Jenson Lake mower (an electric weed cutter) and for the water testing
  • Over $2000 in individual donations from lake residents for the purchase of another Jenson Lake mower

-Equipment

  • Water testing equipment loaned by the Canadian Museum of Nature
  • Boats and motors loaned by members
  • Pontoon donated by….. and adapted to collect the milfoil
  • A manual cutter made available by Kees Metselaar
  • Regular training sessions on the use of the Jenson Lake mower (weed cutter) by Randy Irwin
  • Pontoon donated by Francine Bélander/Robert Rhéaume, Roxanne/Mike Nidd and Luc/Martine Charbonneau

What can you do?

  • Stop sediments from entering the lake (maintain the natural vegetation along the shoreline or restore degraded shorelines). To preserve shoreline vegetation, see the following proposed shrubs:
  • Reduce the amounts of pollutants entering the lake (ensure proper septic systems; use phosphate-free products; do not use fertilizers or pesticides.
  • Control the watermilfoil population by minimizing plant fragmentation. Avoid circulating in areas of the lake infested with the plant (the worst of which are surrounded by buoys) and in shallow areas (where the plant may be present but not yet visible).

If you can donate time and/or equipment, please contact: Brian Castledine

The two Jenson Lake mowers and the pontoon are available to members who would like to tackle the milfoil in their area of the lake.

Please contact Brian Castledine for training and access to the equipment.
