Founded in 2009 as a Quebec not-for-profit organization, the Blue Sea Lake Watershed Association is a membership-based volunteer organization whose mission is to preserve and protect the Blue Sea Lake watershed for present and future generations. We are actively engaged in annual and special projects aimed at understanding and combatting threats to the environmental health of Blue Sea Lake and its tributary lakes and waterways.

These Projects Include:

Carrying out periodic studies and conducting annual monitoring of the water quality and environmental health of the lakes in the watershed.

The deployment of a program of yellow demarcation buoys to warn boaters of Eurasian milfoil, an exotic invasive species, on Blue Sea Lake.

Working with local municipalities and other partners to implement mandatory boat washing and to promote other measures to prevent the introduction of other harmful invasive species into our watershed and to prevent the deterioration of our lakes and waterways.

Launching and leading experiments to address the serious and widespread problem of Eurasian milfoil

Fostering good environmental stewardship and best practices through communication and education of our membership, local authorities, and the broader public.

In 2018, The Blue Sea Lake Watershed Association acquired charitable status under the Canada Revenue Agency, conferring certain tax exemptions and enabling us to issue tax receipts in support of our mission as an organization.

Residents, cottagers, and other individuals become members, donate, and volunteer their time and talents to support the work of the Association to preserve this beautiful watershed that is ecologically sensitive and subject to environmental pressures from human activity locally and beyond the region.
