The Minnesota Department of Natural Resources reminds lakeshore property owners that a permit may be required to remove aquatic plants. Aquatic plants provide food and shelter for fish, ducks and other wildlife. They also stabilize the lake bottom, which helps maintain water clarity, and protect shorelines from erosion by absorbing energy from waves and ice.
Additionally, the DNR frequently receives questions about devices that generate water current to wash muck and plants away. They have various trade names, but the DNR refers to these devices generically as hydraulic jets. Even though you can buy one in Minnesota, they cannot be used in any way that disturbs the bottom of the lake or uproots plants.
Specific regulations govern what situations require permits for aquatic plant removal. Regulations and a guide to aquatic plants can be found on the DNR website. To apply for a permit, visit the DNR’s permitting and reporting system.
