Diquat in gel form will be used to treat aquatic weeds. This work is dependent on suitable weed, water and weather conditions and therefore the timing is subject to change.

Advertisements have been placed in the Otago Daily Times to notify the public of this operation.
We recommend a 24 hour stand-down on swimming, fishing or taking water for irrigation and domestic supply during and once the spraying is complete. This stand down will end at 7:00pm Thursday 19th May.
