Chehalis Knotweed Treatments have begun!

After surveying Rock and Halfway Creek tributaries, the Lewis County Noxious Weed Control team has started Knotweed treatments in Pe Ell. If you have any questions about knotweed control or the long term treatment plan, please reach out to us at Weeds@Lewiscountywa.gov. Because of its ability to easily spread downstream, we must start our efforts at the tributaries of the headwaters of the Chehalis river.
