The South East Queensland (SEQ) region
Overview of the 2011–12 year
The South East Queensland (SEQ) region was generally wet and the rainfall was above average for the 2011–12 year. These rainfall conditions, compared to the record high rainfall observed during the 2010–11 year, contributed to decreased inflows into the urban storages. Because of high storage volume in the 2010–11, water volume in almost all the storages in the SEQ region increased during the 2011–12 year. The volume of water held in storages was 2,479,671 ML compared to 2,219,099 ML at the end of the 2010 –11 year. The closing net water assets in the SEQ region was 2,480,275 ML, compared to 2,218,299 ML at the end of the 2010–11 year.
For more information on the region's water assets refer to Water accounting statements.
The SEQ region's urban water supply system depended on surface water source in the 2011–12 year. In addition to that about 22,900 ML of water was imported to the urban water system.
The key water account information for the SEQ region during the 2011–12 year are presented in the following table. Information on the uncertainty associated with the volumes presented in the table is provided in the relevant sections of the account.
