A recent inspection on 07/01/2025 confirmed the presence of blue-green algae along the banks and shoreline of Spavin Lake. However, a follow-up visit on 07/02/2025 during aquatic plantings found no visible signs of algae.

As conditions can change rapidly, we advise continued caution:

  • Avoid swimming, fishing, or direct contact with the water.
  • Keep pets away from the water.
  • If you or your pet come into contact with the water, rinse thoroughly and remove any wet clothing. If health symptoms appear, seek medical advice and avoid further exposure.

We will continue to monitor the lake and provide updates as needed.

Follow our website or Hume City Council’s Facebook for updates.

What is blue-green Algae?

Blue-green algae naturally occurs in freshwater throughout Australia. Blooms of this algae can occur in response to favourable conditions, which include still or slow-flowing water, abundant sunlight, hot temperatures and sufficient levels of nutrients. 

Blue-green algal blooms are potentially dangerous to human, animal and fish health.

As the name suggests, blue-green algae looks green, but sometimes turns to a blue-like colour when dying.

How long does blue-green algae last?

Blue-green algal blooms can persist for several weeks, sometimes months. This is dependent on the weather and flow conditions. 

Cooler, windy weather or increased flow may reduce or prevent blooms from occurring.
