Wendy Lovell has hit back at Tim Quilty calling the fellow member for Northern Victoria's comments regarding the Murray Darling Basin Plan "dangerous, misleading and disingenuous".
Mr Quilty said he was "disappointed" that fellow Northern Victoria members, including Ms Lovell, had not voted for his motion for the Victorian government to withdraw from the plan.
But Ms Lovell said he failed to publicise that he ended up voting for her amendment.
"What Mr Quilty failed to say was that he and his Liberal Democrat colleague voted for the amendment to his motion that was moved by myself on behalf of the Coalition.
"He did this because he realised it would have delivered a far better result for Victorian irrigators than his own motion.
"Had our amendment passed it would have superseded Mr Quilty's own motion."
Mr Quilty, Ms Lovell, Mark Gepp, Jaclyn Symes and Tania Maxwell all represent Northern Victoria in state parliament.
Mr Quilty's original motion, which he put to parliament on Wednesday, called for Victoria to withdraw from the MDBP completely.
But to do this would be "devastating" to Victorian irrigation communities according to Ms Lovell.
"It would allow the commonwealth to have unfettered access to purchase more of Victoria's High Reliability Water," she said.
"If Mr Quilty's motion had passed the current plan would have stayed in place and Victoria would not have had a seat at the table which would be highly dangerous.

"The Coalition acknowledges that the current plan is not perfect and our irrigators are hurting.
"That is why we moved an amendment to Mr Quilty's motion to remove the words 'withdraw from' and instead call for a 'redraft' of the MDBP.
"We also included a point to highlight that the '450GL of up-water cannot be delivered without doing irreparable social and economic damage to Victorian communities or without flooding private property'."
Three out of the five members for Northern Victoria, Ms Lovell, Mr Quilty and Ms Maxwell, voted to adopt the amended motion with Ms Symes and Mr Gepp voting against it.
The amendment and original motion didn't pass.
"Mr Quilty's simplistic motion just calling to withdraw from the plan has demonstrated the dangers of electing Independents and minor parties who will say or do anything for a headline but never have to consider the ramifications."
Mr Quilty said the major political parties were "turning their backs on northern Victorians" after Ms Lovell and Mr Gepp spoke against his original motion.
