LAKE USE IMPACTS

1. Boats – please minimize or curtail boat traffic during the treatment, as well as for the 24-hour period after. This helps to minimize wave action, which moves the herbicide away from the intended treatment zones.
 
2. Swimming – due to the products we will be using, there will be NO swim restriction on the entire lake, following the application.
 
 

CHEMICALS PLANNED FOR USE
