Liberty Lake residents and users,
This coming Tuesday, August 18th, 2020, LLSWD and our contractor Lakeland Restoration Services will be treating Liberty Lake with herbicide to control aquatic invasive species.
The two target plants are Eurasian watermilfoil and Curlyleaf pondweed. Our treatment is targeted to impact invasive plants only, by using selective herbicides at very low concentrations.
In order to gain the best effects with this effort, LLSWD has gotten permission from Washington Department of Fish and Wildlife (WDFW), to close the public boat launch from 10:00 pm 8/17/20 – through – 6:00 am 8/19/20. This minimizes the wave, wake, and prop action in the water, which helps us to get the most contact time between our target plant species and the aquatic herbicides that are applied to the lake. If you have a boat on the lake already, we ask that you limit your activities on Liberty Lake during the application on 8/18.
AT A MINIMUM: please stay as far away from our treatment boats and treatment areas (see the map below for where those zones are located.
There is a 24 hour recommended swim/primary contact recreation restriction in and around the treatment zones.
You can see much more information about this annual effort to control aquatic invasive species in Liberty Lake HERE.
