Eurasian Watermilfoil
Myriophyllum spicatum

This Class B noxious weed is widespread throughout Washington State. Control is not required but recommended in King County.

Eurasian watermilfoil is a submerged aquatic plant that is present in many lakes in King County, especially lakes with public boat launches.  In order to prevent further spread of this and other aquatic weeds, boaters should clean all vegetation from boats and trailers before moving between lakes.  If Eurasian watermilfoil is detected early enough, it may be possible to control it.  For more information about Eurasian watermilfoil, where it occurs in Washington State, and how to control it, please follow this link to the WA State Department of Ecology.
