Common Aquatic Invasive Species: Eurasian Watermilfoil
This noxious weed forms very dense mats of vegetation on the water’s surface and is transplanted by hitchhiking on vessels and motors. It has feather-like leaves arranged in whorls of four around the stem, which may reach lengths of 10 feet of more. A pink flowering spike appears above the water from June to August.
