Recreational blue-green algae alerts
Being safe is the foundation of a healthy Tweed.
Whenever we detect a blue-green algae bloom:
- do not use water from the affected waterway for domestic use or livestock
- do not eat fish including shellfish from the affected waterway
- do not swim in or undertake recreational activities that involve contact with the affected waterway
- keep animals away.
Never drink untreated dam or river water.
If you come into contact with algae, rinse it off with fresh water. Seek medical advice if symptoms appear.
Affected water may look like it has green, paint-like scum on the water or near the edges, or greenish clumps throughout the water. It can smell musty.
