The Ministry of the Environment, Conservation and Parks has confirmed the presence of blue-green algae (BGA) in a water sample collected at Barton Bay, Kenogamisis Lake on September 16, 2024. This lake is located near Geraldton.
Water should be avoided whenever a BGA bloom is present, and for about 2 weeks after it has gone away. It is important to avoid:
- drinking the water;
- using it for household purposes; or
- swimming in it.
Keep pets away from the water. Their smaller size and habit for drinking lake water makes them more vulnerable.
BGA are microscopic organisms that are naturally present in lakes and streams. They are usually present in low numbers but can rapidly increase in warm, shallow, surface water that gets a lot of sun. When this happens, they can form blooms that make the water look like green pea soup or turquoise paint. The harmful algae bloom may form scum or solid-looking clumps on the water surface and produce toxins than pose a health risk to people and animals when consumed, inhaled, or from skin contact. If contact with BGA occurs, wash with soap and water and rinse with clean water to remove the algae. BGA blooms in lakes in our region have been relatively uncommon, historically. However, with changing climate and rising water temperatures they may become more common.
