Blue-green algae in water

Blue-Green Algae

Blue-green algae are bacteria, but have features in common with algae. Although often blue-green, the algae can range in colour from olive-green to red. Blue-green algae are a natural part of our environment, but contact should be avoided, as some blooms (a large mass or scum in the water) may release toxins. The following notice is posted at some of the area’s public boat launches and marinas.

If observed:

  • Avoid skin contact
  • Do not ingest
  • Keep pets/livestock away
  • Do not eat internal organs of fish caught when blooms are visible or suspected
  • Do not drink, cook or shower with water experiencing an active bloom. Toxins are not removed by boiling. Contact a qualified water treatment specialist.

To report an active bloom call: 1-800-268-6060, TTY: 1-855-889-5775
