Water Minister Penny Wong says there is not enough water currently in the Murray Darling system to fill South Australia's Lower Lakes, no matter what drastic action is taken.
"Even if we did make a decision to not give any allocations, there is insufficient water currently in storage, less the critical human needs issue, for us to viably manage the lower lakes with the amount of water we have," Senator Wong said today.
Her comments follow reports today criticising the effectiveness of the Government's $3 billion water buyback scheme, and predictions that the Lower Lakes will have to be opened to sea water.
There have been calls from the South Australian government for the release of water from the NSW Menindee Lakes to help revive the acidifying Lower Lakes - a call rejected yesterday by NSW Water Minister Nathan Rees.
The Federal Government's water buyback scheme is also unlikely to have enough impact in the short term to assist the lakes due to limitations on the volume of water able to be purchased by the government in any one year.
Regardless, Sen Wong said this morning that even if the Government was able to buy more licences in the short term, the fact remained that there was not enough water in the system to make any difference to the Lower Lakes.
"There's not enough water in the system to bring down the sorts of quantities of water you'd need to fill the lower lakes and handle the evaporation in the lakes and transmission loss, that is what you'd lose along the way," she said.
This is in line with reports yesterday that despite purchasing 34 gigalitres worth of entitlements last year, the lack of water in effect has resulted in just an extra 10 megalitres of environmental flow this season.
Sen Wong yesterday announced that licence acquisitions would begin next month in the Queensland reaches of the Basin.
