Algae are a naturally occurring organism present in all waterways. The Gippsland Lakes contain many different types of algae at varying levels as part of the natural environment and balance of the Lakes system.

Weather conditions, nutrient levels, salinity and water flows all affect the levels of algae and can contribute to the formation of algal blooms on the Lakes.

Warmer weather conditions are likely to lead to a natural increase in the abundance and variety of algae and other organisms in the Lakes.

If an algal bloom develops on the Gippsland Lakes, information (factsheets and maps) will be available on this website and through local outlets, including local media and Visitor Information Centres and circulated to tourism operators. It will also be posted on the DELWP Gippsland Facebook page.

Please see the Gippsland Lakes Algae Factsheet.
