Maine DEP Lake Scorecard 
The Scorecard summarizes many types of lake data into one color-coded graphic, based on current conditions or trends in the lake's health. The color is indicative of an overall condition assessment of each category: blue = good, yellow = fair, and red = poor. Grey indicates there is not enough data for an assessment.
A small number of lakes have more than one hydrologic basin, and there will be scorecards for each basin.
Click the Scorecard image or images below to open the interactive Scorecard and learn more about each of the categories and their respective parameters -- and to get involved!
