The National Capital Authority (NCA) wishes to advise the community and Lake Burley Griffin (the Lake) recreational users that all areas of Lake Burley Griffin are now Open. Water quality sampling and analysis has confirmed a reduction in bacteria levels in all areas.
The Lake was closed from Saturday, 3 September, as a precautionary measure during a minor flooding event.
The NCA undertook water quality sampling at key beach sites. Recent results have confirmed the reduction of bacteria levels, enabling the Lake to be re-opened. Under the Guidelines for Recreational Water Quality, two consecutive negative samples must be obtained before reopening the Lake.
The elevated bacteria levels could be attributed to several sources, including high flows in urban storm-water and domestic and rural animal waste runoff. Ongoing advice from ACT Health is that swimming in receiving waters should be avoided for several days after heavy rainfall as water quality is strongly influenced by these factors and generally leads to short periods of elevated bacterial levels.
WHAT: Change in Water Quality Alert Levels for Lake Burley Griffin
WHERE: All areas are Open
