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:
We will continue to monitor the lake and provide updates as needed.
Follow our website or Hume City Council’s Facebook for updates.

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.
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.
