Lake Tuggeranong’s water quality is improving, but more work is needed to address algal blooms. Two recent reports from the University of Canberra have found that new wetlands constructed by ACT Healthy Waterways in catchment areas are helping to clean stormwater flows entering the lake.

The new infrastructure helps improve water quality by filtering nutrients out of water flowing into the lake.

If left unmitigated, these high nutrients flows contribute to algal blooms, which in turn can produce toxins which make the water harmful to humans and animals.

The University of Canberra research also found that more work is needed to solve Lake Tuggeranong’s algal blooms.

These findings have provided us with a better understanding of water quality challenges.

We will continue to investigate the origins of excessive nutrient loads entering the catchment, and fund projects to introduce more aquatic plants to help filter out nutrients.

The lake is an important area for the Tuggeranong community for recreation and socialising, and reducing algal blooms will ensure that it can be used year-round.

The University of Canberra’s Lake Tuggeranong Research Project was funded through the join ACT-Australian Government Healthy Waterways program.

Twenty individual infrastructure projects were completed through the $93.5 million Healthy Waterways project to improve water quality across the ACT.

The Healthy Waterways project also includes significant education and public awareness campaigns to encourage households and businesses from pouring pollutants into stormwater drains.
