Kitsap County Noxious Weed Control Program and Board

Long Lake Aquatic Invasive Plant Management

Kitsap County has contracted with AquaTechnex to conduct aquatic invasive species control work on Long Lake over the summer and fall of 2024. A notice has been sent by mail to all residents within a quarter mile of Long Lake, which provides more detail on the species being treated and the chemicals being used. AquaTechnex will posts signs in treatment areas within 48 hours of treatment. The signs will describe any water use restrictions or advisories. 

The work being done is part of a Washington State Department of Ecology grant-funded project, with matching funds from Kitsap County's Noxious Weed Control Program. The work will follow guidance provided by the Integrated Aquatic Vegetation Management Plan (IAVMP) developed in 2022. 

For more information about the management of invasive species on Long Lake in previous years, visit the Long Lake Managment District website. Please note, the Long Lake Managment District is not currently active.

What is a noxious weed? 

Noxious weeds are invasive, non-native plants that can threaten agricultural crops, local ecosystems, and human and livestock health. To learn more, see Kitsap County's 2024 Noxious Weed List.

Noxious Weed Control Program Update 

In reconvening Kitsap County's Noxious Weed Control Program, the County Noxious Weed Control Board will work to meet the requirements of state law and local needs. The program will focus on providing education and technical assistance to landowners and the public on ways to control and manage noxious weeds. For immediate noxious weed control and removal services, see the following list of businesses that are known to provide noxious weed control work in Kitsap County: Noxious Weed Control Service Providers.

Why have a Noxious Weed Control Program? 

In 1969, Washington State established RCW 17.10 to limit economic loss and adverse effects to Washington's agricultural, natural, and human resources due to the presence and spread of noxious weeds on all terrestrial and aquatic areas in the state. The law created a state Noxious Weed Control Board and required each county within Washington State to establish their own Noxious Weed Control Program and Board. The Washington State Noxious Weed Control Board annually publishes a list of noxious weeds identified for control and/or monitoring, which must then be adopted by our county Noxious Weed Control Board within 90 days. Listed weeds are separated into three classes: Class A, Class B, and Class C. A description of these classes and the latest state list can be found in the document linked below. 

Identifying and Reporting Noxious Weeds

As a gentle reminder, RCW 17.10 requires landowners to keep noxious weeds from going to seed on their site and spreading to neighboring locations. You can report noxious weeds at Kitsap1 online. The resources listed below may be able to help you identify and manage small instances of noxious weeds on your own. If you have or know of a larger noxious weed infestation, please reach out to Kitsap County's Noxious Weed Control Program Coordinator, Jade Jarvis, at

Kitsap County Noxious Weed Control Board 

Kitsap County's Noxious Weed Control Board consists of five voting members appointed by the county Commissioners, and one non-voting member which is either the director, or appointed by the director of the county WSU extension office. Each voting member represents the geographic area of one of Kitsap County's five school districts, and serves a term of four years. The Noxious Weed Control Board is required to hold a public meeting at least quarterly with a quorum - a majority of voting members present. The Board works closely with the Program Coordinator to provide education and technical assistance in the control of noxious weeds.
