A likely return of El Nino weather conditions later this year and no decent rain forecast for winter has prompted authorities to suggest the drought may never break in the Murray Darling Basin.
The head of the Murray Darling Basin Commission, Wendy Craik, said today farmers and irrigators in the Basin should prepare for the worst as low autumn inflows and poor forecasts point to another season of potentially zero allocations in the southern half of the Murray Darling Basin.
Meanwhile, Bureau of Meteorology modelling from the Indian and Pacific oceans are showing preliminary signs the drought-inducing El Nino weather pattern could make a come-back as early as the end of this year, or during 2009.
Only some rain in near future in the northern part of the Murray Darling Basin provided any glimmer of hope from today's drought brieifing.
BOM's Michael Coghlan said despite heavy summer rain across the Basin, the run-off situation between the end of summer and now had reversed dramatically.
Mr Coghlan said that rain at Christmas was not enough to have any impact on the run-off deficits in south east Queensland or the southern Murray, and over six years rainfall has barely made a dent on the deficit which has built up over that time.
He said above average to record rain was required to get the Basin out of drought, but BOM modelling showed there was only a 5-15pc chance of high rainfall in the southern NSW Snowy Mountains high country, which is the main feeder of water into the southern part of the Basin.
Dr Craik said while storages were slightly better this year compared to the same time last year, the basin was still heading back to the low levels experienced in 2006-2007.
She said the commission was looking at "other measures" for emergency contingency planning of water supplies to advise State and Federal ministers later this year.
This could include buying water from Snowy Hydro to help meet critical human needs along the river, as well as taking more water from tributaries.
Allocations for the next irrigation season were still not known yet and would depend on late autumn and winter inflows, but she conceded the forecasts were not good and farmers should "prepare for the worst".
