Organization Overview

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

LSM trains, certifies, and provides technical support to hundreds of volunteers every year. These volunteers monitor a wide range of indicators for water quality, assess watershed health and function, and screen lakes for invasive aquatic plants and animals. LSM through our robust community science network is the primary source of lake data in the State of Maine. LSM volunteers benefit their local lakes and broader by playing key stewardship and leadership roles.
