Our Mission

Lake Stewards of Maine (LSM) works to protect Maine lakes and to promote lake stewardship through widespread citizen participation in the gathering and dissemination of credible scientific information pertaining to lake health.


LSM is a non-profit 501(c)(3) organization committed to the collection of information pertaining to lake water quality. For 50 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.
