The DNR does not encourage the destruction of aquatic vegetation. However, the DNR recognizes that aquatic plants may interfere with a homeowner's right to reasonable access to open water and recreation. To balance the needs of conservation and those of recreation, the DNR has developed an Aquatic Plant Management Program. This program, operated under Minnesota Rules, requires permits for controlling, planting, or destroying aquatic plants and other organisms in public waters and public waters wetlands. Because plants provide many benefits to the water environment, requests to destroy vegetation are limited to areas where plants seriously interfere with recreational use.
Two common ways to control aquatic plants:
Whichever method of control you choose, the cost of control depends on the size and type of project. Aquatic plant control is temporary because aquatic plants grow back from root crowns, seeds, and other plant parts. Information on permits, costs, treatment methods, and herbicide distributors, is included at this website or from a DNR Fisheries office. You can also discuss control methods with an independent contractor.
