Fighting lake weed threat in Wakatipu

24 July 2017

We lead the control of aquatic weed in the beds of Lake Wakatipu and the Kawarau River.

Lake Wakatipu has been considered weed-free, but the risk of a weed called ‘lagarosiphon’  spreading into the lake from boat users in the Kawarau River is high.

That’s why we established the Lake Wakatipu Aquatic Weed Management Group, which is taking a number of immediate and long-term measures to prevent the spread.

One of these measures is a boat-based control operation in the Frankton Arm of Lake Wakatipu in August. We’ll also be working with councils to buoy off areas of the Kawarau River, set up a checkpoint and remove dead willows.
