At the end of December 2010, Victoria's water storages were at 72.2% of their capacity at full service level of 14,020 GL. This was 3.0 percentage points higher than the level in November 2010, and 41.9 percentage points higher than in December 2009.
Melbourne's water storage level at the end of December 2010 was 53.0% of capacity. This was 1.7 percentage points higher than in November 2010 and 20.4 percentage points higher than in December 2009. Rural water storages held 75.4% of their capacity at the end of December 2010, 3.6 percentage points higher than in November 2010, and 44.1 percentage points higher than the level in December 2009.
Between December 2009 and December 2010, the volume of water held in rural water storages increased by 141.2%. Lake Eildon in the Goulburn basin captured 36.2% of this increase, with a further 37.8% of the increase being in Murray basin storages. Just under three-quarters (73.9%) of the storage capacity at full service level of Victoria's rural water storages (9,396 GL) is represented by Lake Eildon (3,390 GL) and the state's share of Murray basin storages (3,557 GL). From December 2009 to December 2010, the volume of water in Lake Eildon increased from 44.2% of capacity to 75.1%.
The total capacity of the state's storages reduced by 365 GL in April 2009 following the decommissioning of Lake Mokoan, while 38 GL was added to full capacity in June 2009 when the Tarago Reservoir was added to the Melbourne supply system. A summary of changes to total storage capacity since December 2004 can be found in paragraph 14 of the Explanatory Notes.
