Invasive plants have been found in 34 Maine lakes and more infestations are found each year. The only known defense against these non-native plants is education and boat inspection. The plants are carried from lake to lake by unsuspecting boaters who have not cleaned their boats and trailers before moving from one lake to another.
The Sheepscot Lake Association obtained certified inspector status for 11 of its members and began courtesy boat inspections on Labor Day in an effort to protect Sheepscot Lake.
