SEQ WATER GRID

The SEQ Water Grid storage is the combined capacity of South East Queensland's drinking water supply dams. These dams are Wivenhoe, Somerset, North Pine, Hinze, Baroon Pocket, Leslie Harrison, Ewen Maddock, Cooloolabin, Sideling Creek, Lake Macdonald, Little Nerang and Wappa.

The Water Grid storage capacity is calculated by dividing the current volume of water stored in the dams by the combined full supply capacity.

Maroon Maroon Dam is an un-gated dam that operates differently from the other un-gated dams. Instead of flowing over the spillway and safely out of the dam when the dam reaches full supply level, we release water from Maroon Dam through cone valves. More information can be found here.

North Pine (Lake Samsonvale) On 28 January 2025, Seqwater enacted a Reduced Full Supply Level for North Pine Dam. The new level equates to a storage percentage of approximately 54% capacity. This new level will remain in place until dam improvement work is completed on North Pine Dam. View historical dam levels	214, 302 ML	112, 523 ML	52.5%	11:00am 18/05/2025

Somerset On 21 January 2016, temporary full supply levels were enacted for Somerset Dam (80%) and Wivenhoe Dam (90%) as part of the Somerset Dam Improvement Project. On 6 November 2020, the Department of Regional Development, Manufacturing and Water approved an application by Seqwater to amend our resource operations licences to reduced full supply levels at Somerset Dam and Wivenhoe Dam. These amended levels equate to storage percentages of approximately 80% for Somerset Dam and 90% for Wivenhoe Dam. The amended full supply levels will remain in place until current dam improvement works at Somerset Dam are completed. Seqwater will commence flood releases from Wivenhoe Dam and Somerset Dam if storage levels exceed the amended full supply levels as a result of rainfall in the dam catchments.

Dam Improvement Program and reduced Full Supply Levels for North Pine Dam, Somerset Dam and Wivenhoe Dam

Seqwater is currently undertaking its Dam Improvement Program. The program will deliver infrastructure upgrades at a number of Seqwater dams and ensure ongoing safety and security of bulk water supply well into the future.

Whilst the program is underway, Wivenhoe, Somerset and North Pine Dams are operating at a reduced full supply levels.

The changes mean Wivenhoe Dam storage will be maintained at 90% full supply level, Somerset Dam 80% full supply level and North Pine 54% full supply level until upgrades are completed.

The reduced full supply levels mean the SEQ Water Grid at full supply is approximately 87%.
