Dam levels

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.

      In June 2020, Seqwater put in place a Restricted Full Supply Level for Ewen Maddock Dam (part of the Ewen Maddock Dam Upgrade Project). The new level equates to a storage percentage of approximately 60% capacity. This new level will remain in place until the dam embankment work is completed at Ewen Maddock Dam which is expected in 2021. Seqwater will commence releases from Ewen Maddock Dam if storage levels exceed the restricted full supply levels as a result of rainfall in the dam catchments.

These equate to storage percentages of approximately 80% for Somerset Dam and 90% for Wivenhoe Dam. These temporary full supply levels will remain in place until current dam improvement works at Somerset Dam are completed. Seqwater will commence flood releases from Wivenhoe and Somerset dams if storage levels exceed the enacted temporary full supply levels as a result of rainfall in the dam catchments.

Gated releases from North Pine dam

Reduced Full Supply Level for
North Pine Dam

On 27 December 2019, a Reduced Full Supply Level (RFSL) was enacted for North Pine Dam (part of the North Pine Dam upgrade). The new level equates to a storage percentage of approximately 68% capacity. This new level will remain in place until dam improvement work is completed on North Pine Dam.

Seqwater will commence flood releases from North Pine Dam when storage levels exceed the enacted 68% Reduced Full Supply Level as a result of rainfall in the dam catchment.

Temporary Full Supply Levels for
Somerset and Wivenhoe dams

On 21 January 2016, Temporary Full Supply Levels (TFSL) were declared for Somerset Dam and Wivenhoe Dam (part of the Somerset Dam upgrade). These equate to storage percentages of approximately 80% for Somerset Dam and 90% for Wivenhoe Dam. These Temporary Full Supply Levels will remain in place until current dam improvement works at Somerset Dam are completed.

Seqwater will commence flood releases from Wivenhoe and Somerset dams if storage levels exceed the enacted Temporary Full Supply Levels as a result of rainfall in the dam catchments.

Somerset Dam is one of the region's oldest dams and is still an important water storage today
