The North Pine Dam Optimisation Study (PDF, 5.6MB) (NPDOS) presents options for the management of the North Pine Dam during the event of a flood.
The options presented seek to improve the use of existing dam infrastructure during a flood to deliver better flood mitigation outcomes. This study was completed in response to recommendations of the Queensland Flood Commission of Inquiry's final report.
A discussion paper (PDF, 552.2KB) has been developed as a guide to understanding the NPDOS Report, and provides an overview of what the study involved in addition to the preferred option.
The preferred option is a semi-permanent lowering of the full supply volume of North Pine Dam to 90 per cent. This option also includes lowering the flood release triggers to improve the use of the temporary flood storage.
The Queensland Government is seeking your feedback on the options presented in the NPDOS Report. We are particularly interested in feedback on the preferred option.

North Pine Dam (Lake Samsonvale) is located on the North Pine River, north-west of Brisbane. Owned and operated by Seqwater, the North Pine dam is one of the 12 key water supply storages for South East Queensland.
The dam has a full supply capacity of approximately 214,302 megalitres, supplying urban water (including drinking water) to the Moreton Bay region and Brisbane's northern suburbs.
The dam has a catchment area of approximately 345 km2, receiving approximately 1,200 mm of rainfall annually, mostly occurring in summer.
