Water resources update
During March 2013, the total River Murray System inflow was approximately 180 GL, which is well below the long‐term March average of 220 GL. Inflow to Menindee Lakes during March 2013 was 370 GL, with the long‐term average for March around 187 GL.
The total flow to South Australia during March 2013 was approximately 260 GL (including approximately 95 GL of environmental water), compared with 1 025 GL during March 2012. The flow to South Australia currently comprises the April Entitlement Flow and water provided through the Commonwealth Enviromental Water Holder. The volume of environmental water being delivered during April 2013 will be approximately 90 GL.
The major Murray‐Darling Basin Authority (MDBA) controlled storages are holding around 69 per cent capacity. This will support the delivery of water for irrigation and environmental purposes throughout autumn, particularly under ongoing dry conditions.
