Lake Stewards of Maine (LSM) trains volunteers to collect many types of data related to lake health. In addition, LSM collects and catalogs data from other organizations, such as the Maine Audubon, Maine DEP, Maine Inland Fisheries and Wildlife, USGS, and NOAA. LSM and partner data is stored in a long-term and quality assured format on the Lakes of Maine Website.
