Background Information

Swimming or primary contact recreational activities are generally encouraged in the western sections of the Lake.

The Lake has four specified swimming areas - Black Mountain Swimming Area, Weston Park (west) Swimming Area, Weston Park (east) Swimming Area, and Yarralumla Swimming Area.

Weekly samples, obtained in these swimming sites, are tested and reported in accordance with the approved Australian Water Quality Guidelines.

The users of the Lake are advised to exercise caution as recent rain may have brought debris and altered the water quality conditions. Water quality in the Lake is subject to environmental variations in the lake itself and in its catchments.

The National Capital Authority provides weekly updates on the water quality of Lake Burley Griffin on its website. This information is usually available on Friday each week. When the situation is warranted, due to changes in water quality conditions, additional reports are listed on the web site.
