North Pine Dam Optimisation Study

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.

Discussion Paper

The discussion paper (PDF, 552.2KB) is 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 sought feedback on the options presented in the NPDOS Report, with particular interest in feedback on the preferred option.


The consultation period closed on 30 June 2014.

There was one session held at the Pendicup Community Centre on Tuesday 27 May 2014.
