Milfoil infestation continues to plague Okanagan watershed

It has been more than 50 years since the invasive Eurasian milfoil emerged in the Okanagan Water Basin.

The weed growth has no maintenance cure, as the plants were introduced and have since spread throughout the Okanagan Valley watershed from Osoyoos to the north end of Okanagan Lake.

Some 4,100 metric tonnes of milfoil have been harvested since 1981, as the Okanagan Basin Water Board continues to fund a milfoil control program which entails derooting or rototilling in the winter and harvesting in the summer at a cost of $780,000 annually.
