As a Lewis County landowner, you might have one (or many) noxious weeds that are causing you concern, or that you may be legally required to control. We've compiled a list of some common weeds that occur in Lewis County. To this list, we've also added some weeds that we consider "high priority" noxious weeds, as they are not yet widespread or they pose a particular threat to our economy, our ecosystem, or our health. These are organized, for you, into the following categories: Class As, Class Bs, Class Cs, and Aquatic Weeds.

This year (2022) your noxious weed control team began recording noxious weed infestations on iform to be displayed on this map. Although many infestations noted this year have not yet been uploaded, in addition to missing most historical records, we believe this is a great start to a more manageable and efficient tracking system.
