Our plans to control milfoil have followed two tracks: 1) measures designed to slow the spread of the weed—such as buoys, boating restrictions, etc. and 2) direct treatment.
Research indicates that clearing limited areas adjacent to the shoreline can best be accomplished in 2 ways:
1. by careful manual removal methods and
2. by covering some areas with burlap
Devices for removing milfoil
The Task Force has explored the use of specialized milfoil control tools and has accumulated a set of best practices which have been effective elsewhere. One of the best devices found so far is the "Weed-Ripper" (click on the corresponding green tab below). Great care must be taken to ensure weeds are pulled out by the roots, and any fragments harvested and destroyed.
Similarly, the Task Force is exploring how best to apply burlap effectively to cover limited areas (click on the corresponding green tab below).
Unfortunately, Provincial regulations currently prevent these measures without obtaining government permits for each separate activity. The process for obtaining permits is expensive and time consuming; we are looking into that as well.
Your Association is endeavouring to clarify the situation and provide guidance. In the meantime, we urge all residents to follow boating guidelines to limit the spread of this invasive weed on our lake until more active methods of control can be applied.

An effective way to control milfoil is to smother the weed beds by covering them with biodegradable burlap (jute) and weighing the corners down with biodegradable sandbags. The burlap process kills the Milfoil off by holding the frail Milfoil plant to the lake bottom. Tested by ABV des 7, local company Block-Aid has invented the DIY Dock Kit that includes a burlap fabric sheet which covers a 12.5 ft wide X 33ft long (3.8m X 10m) area along with 18 empty burlap sand bags and instructions.
Some lake residents have reported success using burlap rolls ordered from this Canadian company.
- Learn how to identify Eurasian water-milfoil and how to prevent accidentally spreading this plant with your watercraft or fishing equipment.
- Avoid infested areas or reduce your speed when travelling near Eurasian water-milfoil infestations. Your propeller can break off fragments and spread the pieces to new areas. New plants can grow from small pieces of the plant.
- Inspect your boat, trailer and equipment after each use. Remove all plants, animals and mud before moving to a new waterbody.
- Avoid planting Eurasian water-milfoil in your aquarium or water garden. Aquarium hobbyists and water gardeners should only use native or non-invasive plants and are encouraged to ask retailers for plants that are not invasive.
- Never release unwanted aquarium plants or pets. Return or donate unwanted plants to a garden centre or pet store, or put them in the garbage. Do not put them in the compost or discard them in natural areas. Discarded plants may produce seeds that can sprout.
- If you’ve seen Eurasian water-milfoil or other invasive species in Lac Gauvreau, please contact Enviro Lac Gauvreau at email@example.com to report a sighting.
- Wash all boats (including canoes and kayaks and water toys) thoroughly before putting them in the water. Cross-contamination between lakes contributes to the spreading of the Eurasian Milfoil.
- Avoid boating, fishing and swimming in all areas marked by a buoy and areas dense in weeds. Any movement contributes to fragmentation and spreading of the weeds.
- Do not pull out weeds by hand in shallow areas, as it will contribute to fragmentation and spreading of the weeds.
