THE Victorian Government has called for a cut to the amount of environmental water to be recovered under the Murray Darling Basin Plan.
Modelling commissioned by the Government as part of its response to the draft plan shows no significant difference in environmental outcomes at key sites if only 2100GL was recovered instead of the 2750GL called for under the draft plan.
The draft basin plan proposes 2750GL be diverted from irrigators to the environment, with the lion’s share being recovered from Riverina and Victorian irrigators.
However, the Government says there should be a smarter approach to environmental watering.
Victorian Water Minister Peter Walsh said the findings could save the Commonwealth up to $1.3 billion if the lower figure were included in the plan.
“The health of the Murray, including the Coorong, Lower Lakes and Murray Mouth can be secured by using less water than what has been proposed by the draft Basin Plan,” Mr Walsh said.
“This would leave more water for food production and provide a future for the hundreds of communities that rely on the Murray for their livelihoods.”
The modelling, by Sinclair Knight Mertz, shows works using regulators, pipes and pumps and changes to river operations and rules can be used to achieve the same environmental outcomes as 2750GL of water.
The SKM report shows if only 2100GL was recovered then the Lower Lakes would be above 0.35m in 72 per cent of years and would only fall below zero in one year.
The modelling was done with a package provided by the Murray Darling Basin Authority.
In its submission to the draft plan the Victorian Government criticised the 2750GL as severe and “unacceptable, especially given the MDBA’s proposals and the high level of uncertainty in the plan.”
Mr Walsh said the report shows the money set aside for buybacks should instead be invested in works to improve the rivers management.
