SEQ dam levels

TThe current drinking water supply capacity of the Grid Twelve is 78.2%, a decrease of 0.5% from 13 April 2017. The Grid Twelve makes up nearly 90% of South East Queensland’s total water storage volume. See below for further breakdowns:

* Catchment rainfall is the average of rainfalls recorded in and around the dam catchment.

** On 21 January 2016, temporary full supply levels were enacted for Somerset Dam and Wivenhoe Dam (part of the Somerset Dam Improvement Project). 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.

SEQ water consumption figures*

Average daily residential water consumption across South East Queensland for the 14 day period ending 19 April 2017 was 166 litres per person. This is a decrease from the previous period of 163 litres per person (calculated over 14 days ending 12 April 2017).

Average daily residential water consumption for a similar time last year was 176 litres per person. Across South East Queensland, residents are currently consuming about 13 litres less water per person per day as they did this time last year.
