Inland Lakes ManagementContact: Aquatic Nuisance Control Program Staff
Although aquatic plants are a natural component of every aquatic ecosystem, excessive plant growth can sometimes be a nuisance for riparian property owners and other lake users. A few species of aquatic plants, such as Eurasian watermilfoil, are not native to the Great Lakes region and can significantly alter the aquatic ecosystem if left unchecked. Permits are required to chemically control nuisance aquatic plants, algae, and swimmer's itch. Program staff regulate the use of pesticides through the permit process. Each application for a permit must undergo a thorough review to assess the environmental impact to the waterbody, and any human health and safety issues. Program staff also review new chemical products proposed for use in Michigan waters, survey Michigan lakes to determine the composition of the native plant community and any presence of exotic plant species, and seek to educate riparian property owners about the management of aquatic plants and a variety of related lake management issues.
