The City of Kenmore is committed to improving access to the waterfront for residents and visitors and is further committed to managing our waters to enhance the enjoyment of this natural resource. Thanks to a grant from the Washington State Department of Ecology, with input from citizens and technical support from Herrera Environmental Services, the City of Kenmore has created an Integrated Aquatic Vegetation Management Plan (IAVMP) as a living, guiding document for the management of aquatic noxious weeds in the portions of the Sammamish River and Lake Washington within the City of Kenmore.

Integrated Aquatic Vegetation Management Plan (IAVMP) 

The City of Kenmore has contracted with Northwest Aquatic Ecosystems to treat areas of Lake Washington and Sammamish River with herbicides to control the growth and spread of Eurasian watermilfoil, Brazilian Egeria and other nuisance plants. Treatment will occur on May 28, 2019 and July 16-18, 2019. If you have any questions, please call the City's consultant Doug Dorling with Northwest Aquatic Ecosystems at (360) 357-3285, or email
