Avoid the Spread of Eurasian Milfoil - Pay Heed to the Yellow Buoys! Why?

April 2018 - It's time to recall the danger of Eurasian milfoil for the health of our lakes and the importance of avoiding areas delimited by the yellow buoys installed by the Association to indicate the boueesjaunesschemapresence of milfoil bed, areas that boaters must avoid.

Eurasian milfoil reproduces mainly by fragmentation of the stems. The stems are broken naturally or cut accidentally (fishermen, boat propellers, etc.) These fragments are then deposited elsewhere at the bottom of the water. Each fragment of one centimetre or more can produce a new plant.

Eurasian milfoil beds become so dense that other species of aquatic plants naturally present are eliminated. Thus, there are fewer aquatic plant species in our waters. This loss of biodiversity results in an impoverishment of the aquatic environment. This plant can also significantly harm fishing, among others lake trout fishing. Finally, Eurasian milfoil is also a constraint to the use of aquatic environments for human recreational purposes.

Association Priorities

In the fall of 2017, the Association's Board of Directors set the priorities for 2018. These priorities are:

  • Continue to work with the municipalities of Blue Sea and Messines to fully implement the program of mandatory boat washing established this year.
  • Continue water testing in Blue Sea and other lakes in the watershed under the RSVL program.
  • Continue our efforts to control the serious Eurasian Milfoil problem in Blue Sea Lake by generating public awareness, expanding the network of demarcation buoys, and the implementation of a jute tarp program (see below).
  • Search for a resolution to the high water levels, with consequential shoreline erosion and property damage, affecting Blue Sea Lake, Blue Sea Stream, and Grant Lake.
  • Encourage a broader participation in our watershed protection activities through volunteers residing along Blue Sea and other lakes in the watershed.
  • Expand our outreach efforts to other watershed organizations in the region and beyond, in order to identify common issues and share knowledge.
