Keeping our waterways healthy

Serious aquatic weeds like Water Hyacinth, Salvinia and Cabomba are very invasive and out-compete local species. Weeds affect the local ecology and water quality and adversely affect bushland, wetlands, waterways and lakes. Weeds are able to reproduce from even the smallest of fragments or seeds. Trying to control these weeds is time consuming and costly.

What can you do to help?

  • Remove all visible mud and plants from your equipment, boats, trailers, boots, crab pots etc before leaving our lakes
  • Eliminate water from all equipment before transporting it anywhere, as the water may contain plant fragments or seeds
  • Clean and dry anything that came into contact with the water
  • Clean boats, motors, trailers, floats, anchors etc before leaving. If possible allow the equipment to dry for about five days before entering new waters
  • Don't release or put plants, fish or other animals into a body of water they did not come from. This is an important step to prevent the spread of introduced species of plants and animals into our waterways.

How you can help protect our drinking water supply

  • Leave the facilities as you found them. Do not cause damage to any property, flora or fauna
  • Place litter in the bins provided
  • Control your pets in the designated areas. Dogs and other domestic animals can disturb the wildlife that live in our natural areas. 

Common weeds

Water Hyacynth

A floating, aquatic weed with attractive light purple flowers. Water hyacinth is capable of reproducing very rapidly through either runners or stolons and can form dense mats where these plants have been introduced.


Dense infestations restrict navigation and water access. Can deoxygenate water, resulting in the death of fish and other aquatic life. Light penetration and pH levels are reduced. Stranded animals may drown.


An aggressive invader of freshwater systems, particularly if they are nutrient rich. It is a fully submerged aquatic plant that competes with native freshwater plants. It can impede aquatic recreational activities and drowning is a risk for entangled swimmers.
