Help Protect
Maine Lakes


Lake Stewards of Maine (LSM), formerly Maine Volunteer Lake Monitoring Program (VLMP), fosters stewardship of Maine lakes and their watersheds in order to ensure high water quality and ecological integrity. This is accomplished by the collection of credible lake data by trained citizen volunteers, and by providing educational information concerning lakes to the citizens of Maine.  LSM is Maine’s leader in providing training and certification in the collection of lake data by volunteers, state agency personnel, educators, consultants and others.

LSM develops and disseminates educational materials concerning various aspects of lakes and their watersheds, including water quality, ecology, management, protection and stewardship. LSM acts as a liaison, when possible, to bring together groups and organizations with missions similar to ours to maximize the benefits of collaborative synergy.

A number of organizations work on behalf of Maine’s lakes and ponds. Some focus specifically on advocacy; others primarily on public education. To some extent, LSM’s mission overlaps with those of other entities. All are working in various ways to protect lakes. What sets the LSM apart is the particular role the organization plays within this larger statewide effort, a role that helps to support the work of those other efforts at the state, regional and local levels.  Reliable information about Maine lakes, both individually and collectively, is the foundation of all efforts to protect, manage and restore these resources.

Our Mission
