. Wilson Lake is classified as "good" under the Maine Department of Environmental Protection water quality parameters. The Wilson Lake watershed covers . The watershed is currently 79% forested, 8% developed, and has 49% buildable area. The Wilson Lake shoreline is primarily composed of low density residential houses and camps (63%). The majority of structures (70%) are within 50 feet of the shoreline. Wilson Lake water quality has been measured since 1977. During this period 29 years of secchi disk transparency data, 9 years of phosphorus data, 5 years of chlorophyll-a (Chl-a) data, and 17 years of dissolved oxygen (DO) data has been taken. From this data, the median total phosphorus (TP) concentration in 2008 was 6.5 parts per billion (ppb) and mean secchi disk transparency was . The Wilson Lake Association was established to maintain a program that will reverse any trend of degrading water quality. The associations also encourages all of the lake's stakeholders to be involved and support cooperative efforts to reduce or eliminate the impact of contaminants on lake water quality.
