Aquatic plants in King County lakes
A necessary component of lake life
Aquatic plants are an important component of lake systems. These plants may be totally submerged beneath the lake surface, floating, or growing along the shoreline. They provide food and shelter for bugs, fish and other organisms, prevent shoreline erosion, filter pollutants from adjacent shoreline activities, and provide oxygen to the surrounding environment.
Native vs. noxious plants
Native species, which evolved with other Northwest plants and animals, generally have natural population controls which keep their coverage in check. Increasingly, problems with aquatic plants generally stem from the presence of noxious aquatic weed species (e.g. Eurasian watermilfoil) or introduced ornamental species (e.g. white and pink water lilies) which tend to grow unchecked, crowding out native species.
