The NCA is lowering the water level of Lake Burley Griffin to support construction works for the Scrivener Dam Dissipator Strengthening Project.

The water level will be lowered by up to 250 millimetres with an additional drawdown of up to 250mm scheduled to take place in May, if required.

The water level will remain up to 500mm below normal levels until construction works for the Scrivener Dam Dissipator Strengthening Project are completed. 

The National Capital Authority (NCA) is undertaking a refresh of the tired and deteriorated existing ‘red’ vehicular directional and interpretive signage to improve the aesthetic across the National Triangle. This will incorporate the new National Triangle branding and update the content to reflect contemporary style in telling our Nation’s stories, both in the recent past and much further back to First Nations experiences.
