WATER RESOURCES

At the end of September 2010, Victoria's water storages were at 59.6% of their capacity at full service level of 14,020 GL. This was 13.8 percentage points higher than the level in August 2010, and 30.4 percentage points higher than in September 2009.

Melbourne's water storage level at the end of September 2010 was 46.9% of capacity. This was 5.7 percentage point higher than in August 2010 and 14.3 percentage points higher than in September 2009. Rural water storages held 62.1% of their capacity at the end of September 2010, 14.4 percentage points higher than in August 2010, and 32.2 percentage points higher than the level in September 2009.

Between September 2009 and September 2010, the volume of water held in rural water storages increased by 107.8%. Lake Eildon in the Goulburn basin captured 35.9% of this increase, with a further 36.6% 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 September 2009 to September 2010, the volume of water in Lake Eildon increased from 26.8% of capacity to 58.8%.

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 11 of the Explanatory Notes.
