Help Protect
Maine Lakes


An Update from Lake Stewards of Maine


2021 marks a very special milestone for LSM. Fifty years ago, a small group of lake professionals, academics, and other lake conservation-minded visionaries, created a plan for safeguarding the health of Maine’s extraordinary lakes. LSM and the incredible volunteer network we orchestrate are the culmination of that plan. To learn more about the history, some of the many people involved, and where we intend to go, please scroll down through this, our 50th Anniversary page. We will be updating it with new content all year long!

Our Mission

The Mission of the Maine Volunteer Lake Monitoring Program is to help protect Maine lakes through widespread citizen participation in the gathering and dissemination of credible scientific information pertaining to lake health. The VLMP trains, certifies and provides technical support to hundreds of volunteers who monitor a wide range of indicators of water quality, assess watershed health and function, and screen lakes for invasive aquatic plants and animals. In addition to being the primary source of lake data in the State of Maine, VLMP volunteers benefit their local lakes by playing key stewardship and leadership roles in their communities.


The VLMP is a non-profit 501(c)(3) organization committed to the collection of information pertaining to lake water quality. For 40 years, trained volunteers throughout Maine have donated their time so that we may all learn more about one of Maine’s most beautiful and important resources — our lakes.
