Aquatic Weed Management Plan

The City has been managing aquatic plants in Lake Stevens since the late 2000s. Management efforts began to treat and manage the spread of Eurasian Milfoil, a noxious weed in the State of Washington. Through years of proactive management, the impact of the Eurasian Milfoil in Lake Stevens has dramatically decreased. The eradication of Eurasian Milfoil has opened the opportunity for other native and invasive aquatic plant growth. Annually, the City surveys the Lake to evaluate the aquatic plant distribution and species to develop a treatment plan.
