Water allocation update
There is no increase in Murrumbidgee regulated river general security allocation at this time.
Given the dry conditions experienced in June and July, combined with storage inflows tracking close to historical minimums, there is no improvement to resources. Caution has been applied to the operational loss allowance to ensure irrigation supplies can be delivered in full despite the dry seasonal outlook.
This assessment is based on an updated carryover volume of 27 per cent of entitlement, meaning that overall general security water availability is 47 per cent of entitlement. Interestingly, about 90 per cent of general security licence holders carried over the maximum 30 per cent of entitlement.
The NSW Office of Environment and Heritage (OEH) commenced an in-stream environmental watering action from Murrumbidgee storages on 24 July 2017 aimed at improving condition of the mid-Murrumbidgee wetlands and stimulating native fish migration. This watering is scheduled to continue until mid-August 2017.
Storage levels (as at 31 July)
- Blowering Dam is 78 per cent full – falling – holding 1,283,000 megalitres (ML).
- Burrinjuck Dam is 56 per cent full – falling – holding 579,000 ML.
The Bureau of Meteorology seasonal outlook indicates that below average rainfall conditions over much of the Murrumbidgee Valley are likely to continue from August to October, particularly in August. It is also highly likely that above average temperatures will continue over the coming three months, with greater than 80 per cent chance of warmer than average days and nights.
Both of Australia’s major climate drivers at this time of year, the El Niño–Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD), continue to remain neutral.
Trade into (and within) the Murrumbidgee Valley is open, and trade out of the Murrumbidgee Valley opened on Friday, 28 July 2017.
