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.

North Pine (Lake Samsonvale) On 27 December 2019, Seqwater enacted a Reduced Full Supply Level 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.

Somerset On 6 November 2020, the Department of Natural Resources, Mines and Energy approved an application by Seqwater to amend the full supply levels for Somerset Dam and Wivenhoe Dam (part of the Somerset Dam Upgrade). 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 and Somerset dams if storage levels exceed the amended full supply levels as a result of rainfall in the dam catchments.

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.

Amended full supply levels for
Somerset and Wivenhoe dams

On 6 November 2020, the Department of Natural Resources, Mines and Energy approved an application by Seqwater to amend the full supply levels for Somerset Dam and Wivenhoe Dam (part of the Somerset Dam Upgrade). 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 and Somerset dams if storage levels exceed the amended 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
