Weed eradication operation

Progress updates - weed eradication operation 2019-2020

Identify lakes for treatment Lakes Ngatu, Waiperera and Ngakeketo South are chosen for weed eradication, the operation will take place between the dates Monday 07 September 2020 and Friday 25 September 2020. Each lake treatment will take less than a day, and we’re hoping to get all three lakes treated on the same day.
Application to EPA Applications lodged with the EPA (Environment Protection Authority).
Approval received Approval from EPA to treat Lakes Ngatu, Waiparera and Ngakeketo South with Aquathol K as a whole lake treatment (a single treatment).
Public engagement Open day for residents and locals held at Lake Ngatu in July 2019.
Application to lakes The choice of application date is dependent on a number of factors, including weather and herbicide supply. If any other major events affect the proposed timing, the new date of the operation will be updated here. There was previously a delay in the shipment of the herbicide from the USA last year, December 2019. We now have the herbicide and will carrying out the operation in Spring 2020. Spring treatment offers cooler water which has a positive effect on contact time of the herbicide with the weeds. The later in the growing season we go, the more established and resilient the weeds become to eradication efforts. Increased recreation in the summer is another consideration in the proposed dates of the operation.
Notifications We’ll be writing to all notifiable parties to update them on the proposed dates of the operations.
Warnings and restrictions During deployment, signs will be erected at the lakes prior to the operation beginning, advising of water restrictions. There will be a public notice in the Northern Age newspaper.
