Aquatic vegetation is essential to a healthy lake. However, the persistence of invasive aquatic weeds, such as curlyleaf pondweed, can degrade water quality and make lakes unusable for swimming, fishing and other activities.

The City of Plymouth occasionally prepares aquatic vegetation reports for various lakes in the city.
