Lake Macdonald is located in the Noosa hinterland and is part of South East Queensland’s drinking water supply.

It is an un-gated dam, meaning that when it reaches 100 per cent capacity, water flows over the spillway and safely out of the dam. If you would like to be notified when Lake Macdonald (Six Mile Creek) Dam begins to spill, please sign up to our free dam release notification service.

Dam Improvement Program

Seqwater has commenced its Dam Improvement Program to ensure the region’s dams continue to meet national standards. The program will see us upgrade some dams and reduce the water levels of others until such time as upgrade works can be completed.

Lake Macdonald (Six Mile Creek Dam) is one of the six dams included in Seqwater’s Dam Improvement Program.
