Cattail and water milfoil grew around the lake. Like some Maine lakes, Messalonskee Lake has seen infestations of Milfoil. In 2005, infestations of Eurasian water milfoil were discovered. An infestation of Eurasian milfoil was controlled using herbicide in 2004. The milfoil weevil ("Euhrychiopsis lecontei") has also been used as biocontrol. In 2006, Eurasian milfoil, an aquatic invasive species, was discovered in Priest Lake. They also eat many aquatic plants such as lilies and water milfoil. Lake Buel suffers from an infestation of milfoil ("Myriophyllum spicatum"). It seems to be associated with floating vegetation such as Hornwort and Water Milfoil ("Myriophyllum"). To the untrained eye, whorled water milfoil can look similar to other species. Little Sebago Lake has been experiencing problems with milfoil for years. A paddle boat, moored in the lake, is used to cut the milfoil. The Tennessee Valley Authority detected milfoil in its waters in the 1960s. Lake Rescue was free of milfoil from 2004 until the last several years. From 1999 to 2003 paid divers searched and removed about 100 milfoil plants.
