The Washington State Dept. of Ecology designed this guide for people who do not have a scientific background, but it may also be useful for professionals who need assistance in identifying aquatic species. Most aquatic plants in Washington are included. It is a wealth of information.
Below is PART 1 of a 2 PART video of the presentation to Ames Lake homeowners (2018). Ben Peterson, Aquatic Noxious Weed Specialist from King County Dept. of Ecology, presents the benefits of aquatic plants, invasive species, submerged plants, pest control, and noxious plants control methods.
The WA State Noxious Weed Control Board advises the WA State Dept. of Agriculture about weed control in our state. Here you'll find alternative plants to noxious/invasive species that will thrive in our lake setting.
