Watershed Survey

Watershed Survey

Learn how to identify, monitor, and mitigate polluted stormwater runoff and other ways in which watershed land use influences lake water quality.

Maine Lake Date

Maine Lake Data

Learn more about your lake and other lakes in Maine. Find information on water quality, aquatic species, invasives, and amenities.

Professional, efficient & helpful

Debbie and Dale Broderick

Dale and I had our first experience with LSM through their online plant ID course during COVID-19. We have been impressed at how professional, efficient and helpful everybody has been in all our interactions with them. They are always willing to enthusiastically share their love of lakes with us. Though we have yet to meet the team members in person, we feel strongly connected to them, as friends who have a lot in common.

Valuable technical content

Beacon of knowledge & resources

Bunny & Ross Wescott

At the beginning of the millennium when we were worried about invasives coming to Panther Pond, we were working in the dark; then we found LSM which has been our beacon of knowledge and resources ever since.
