LSM Survey 123 Information


Using the Esri Survey 123 App to Document IAP Screening Surveys

Took place on Tuesday, June 30
LSM’s IAP Screening Survey Documentation forms have gone digital! With the help of our friends at the Maine DEP, IPPers now have the option of recording screening survey data on their smartphones or tablets. Paper data forms are still perfectly functional and welcome; but for those of you who wish to go paperless, you now have a great new tool. Attend this webinar with Becky Schaffner and Denise Blanchette from the Maine DEP to learn all about the app and how to get started!

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.
