Bloom warning removed from Mill Park Lakes wetlands

Algal Bloom

Melbourne Water testing has confirmed that the blue-green algal bloom affecting Mill Park Lakes wetlands in Mill park has cleared. 

Blue-green algae or cyanobacteria are a common seasonal occurrence in Victoria. They are a natural component of most freshwater systems, including streams and lakes but are rarer in estuaries and the sea. Blooms can be triggered by nutrient levels, low inflows, lower storage volumes and warmer weather conditions. 

Blooms can be unsightly, ranging in colour from dark-green to yellowish-brown. They develop a paint-like consistency as they dry out and often have a pungent smell.
