At 8 March 2012, the reservoirs in the Brisbane water collection area were 86.0% full, holding approximately 1,908.8 GL. At the same time in 2011, these reservoirs were 87.1% full, holding 1,802.6 GL. Although the amount of water stored rose by 106.2 GL, or 5.9%, over the year, this increase may not be fully reflected in the 'percentage full' figure for 2012, owing to a change in the holding capacity of Brisbane's reservoirs during the same period.
At 8 March 2012, the reservoirs servicing Canberra, Darwin, Hobart and Sydney were near 100% capacity while Perth had the lowest reservoir levels, at 24.1% full.
Information on reservoir levels is collected, standardised and disseminated by the Bureau of Meteorology (BOM). This information includes the total volume of accessible water stored in public water storage facilities (e.g. dams) with a capacity over one gigalitre (GL) as well as the total capacity of water storage facilities in the region (% full).
