The Queensland Opposition has called on the Government to scrap plans to build the proposed Traveston Crossing dam near Gympie in the state's south-east.

Queensland's coordinator-general has sent his final report to federal Environment Minister Peter Garrett, who has at least 30 days to consider the report.

It includes 1,200 conditions that address environmental and social issues surrounding the project.

Queensland Opposition spokesman David Gibson says the report is further evidence that construction should not go ahead and he has called on Premier Anna Bligh to cancel the project.

"If she has any environmental concerns or credibility at all left in her she should walk away from this project," he said.

"Any project that has over 1,200 environmental conditions associated with it clearly is a project that is of great risk to the environment and one that we don't need to pursue - there are other alternatives.

"With any project there would be conditions, but over 1,200 conditions is extensive and for the Premier to try and spin this as being the most environmentally friendly and greenest dam ever built just hides the fact that this dam is a risk to the environment."

Community input

A group fighting to stop the dam's construction wants Mr Garrett to take his time to consider the project.

Save the Mary River Coordinating Group spokesman David Kruetz says Mr Garrett should give the community a say about the dam.

"We would call on Mr Garrett to allow a public consultation period that would stop the clock for 10 days that people would have to comment on this EIS [environmental impact statement] report from the coordinator-general's department," he said.

Mr Kruetz says there are still a lot of questions to be answered.

"We think the science will not stack up - and 1,200 conditions, 38 major conditions and a 10-year sunset clause - if they can't meet those conditions, they can't build the dam," he said.

"[This] would say to any reasonable person that this has extreme environmental problems."
