Current and upcoming aquatic weed control work
Before undertaking any control work, we notify the public in a range of ways including putting up signs near affected areas, publishing notices in local papers, broadcasting notices on radio and posting information on this website.
Most of our control work is weather dependent, so published dates may change at short notice. We try to avoid carrying out any spraying that will impact on weekends and public holidays.
The page below provides detailed information about our aquatic weed control work by region.
