If you Can’t Beat the Milfoil – Rototill It!

Aquatic Invasive Species Eurasian Watermilfoil

Okanagan Basin Water Board (Canada) built and operates three milfoil rototillers that have been in use for several decades. The machines were built for the sole purpose of chewing up the bottom of the lake and loosening up the roots of aquatic plants, especially Eurasian watermilfoil.

The program started when the Eurasian Milfoil weed was so bad it was impossible for people to use some of the main public beaches on Okanagan lakes.

The milfoil rototiller literally chews up the bottom of the lake, loosening up the roots of the plants that then float to the surface. They freeze and die in the cold winter temperatures resulting in clean open beaches in the summer.
