View Current Water Quality Conditions on Maine Lakes

The goal of this Near Real-Time Lake Data Pilot Project is to provide volunteers and the public with a statewide perspective on current water quality conditions for several lakes that are geographically distributed throughout Maine. Lake water clarity (aka: transparency) is an important and reliable indicator of lake health. Click on the image below to view current water clarity conditions for the pilot lakes. The information is updated regularly by participating certified VLMP lake monitors. Check back frequently to see how water clarity conditions vary from lake to lake, region to region, throughout the monitoring season.

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.
