The committee identified the need for a weir about three years ago as a way to secure and conserve water for the lake.

Construction work then started on a weir with approval from relevant groups except Parks Victoria.

The authority, which manages the land, stopped the work towards the end of 2016 because a required environmental impact assessment was not completed before the project started.

Parks Victoria met with the committee on Wednesday to discuss the project.

The authority agreed to seek permits and investigate the costs of completing a weir with a modified design.

An environmental impact assessment by the authority found that the new weir could impact to the area around the lake and the broader wetland system.

However, this issue could be controlled with a modified design to allow the weir's height to be adjusted to different water levels.

Parks Victoria regional director Sally Lewis said the authority has decided to take on the project, which would still require legal, safety, environmental, cultural heritage, and regulatory checks, and a cost-assessment.

She said any construction at the site must be done in an environmentally responsible manner.

"While this has been a complex matter to resolve, there is now an evidenced-based environmental impact assessment from which we can explore construction of a weir with a modified design, subject to approvals," she said.

"Following a full and frank meeting with the committee, we've committed to working together to progress the legal, safety, environmental, cultural heritage, and regulatory checks on this project."

Committee member Brian Klowss said Parks Victoria's commitment was not enough and the committee would keep fighting for the project..

"Parks has committed that it will happen, but they won't commit to when or how and they have no funding for the project," he said.

"They crucified locals when they stopped the project and now they are happy for it to go ahead, but there is no money for it.

"We had money for it three years ago."

Mr Klowss said the meeting involved some "heated discussions."

"Parks kept saying they would build the weir when they got the money, but there is no contingency plan in place," he said.

"So when we will see it being built, who would know.

"We are in no better position than we were when we started."

Mr Klowss said the committee would now lobby other areas of government to try to get some funding for the project.

"It's just not going anywhere - we have to keep it going with ministers on a political level," he said.

"This has been going on for three years now and we just want it done."
