Question: I want to control aquatic plants by cutting, raking or chemical treatment.
Answer: Aquatic plants are essential to good fishing and clean water and actually stabilize shorelines. You will want to limit removal as much as possible in most situations. The Department has new rules regarding aquatic plant removal. Contact the DNR Aquatic Plant Manager nearest your project site for additional and up-to-date information.
