NO TILLEGRA DAM
The Tillegra Dam is ill-conceived – its construction was not on the radar of Hunter Water for the next 20 years or more yet it has been thrust forward as a ‘quick-fix’ political decision.
The Williams River valley already has one dam – the Chichester Dam – plus further regulation to natural flows at the Seaham Weir. A second dam at Tillegra would put an end to the natural floods and freshes that keep the river healthy and top up the fertility of farmland.
The cheapest water is usually the closest. Pumping water over long distances is expensive.
The best solution for the Central Coast is to source its water locally: by collecting rainwater from house roofs; by maximising the value of Mangrove and Mardi Dams, linking the two; by implementing existing plans to harvest stormwater flows in the Wyong River and Ourimbah Creek. These strategies should be implemented before consideration is given to building the Tillegra Dam.
Newcastle Herald (16 Nov 2009)
A STUTTERING barred frog has been discovered on the proposed Tillegra Dam site, bringing new hope to the fight against the project.
University of Newcastle Associate Professor in biological sciences Michael Mahony formally identified the endangered frog yesterday, which was found on a Dungog property in January and later handed over to the No Tillegra Dam Group.
The discovery called into question the integrity of Hunter Water’s environmental assessment report and was another blow to its “flawed” ecological assessment of the dam site, Greens MP John Kaye said.
Mr Kaye said a six-day fauna survey commissioned by Hunter Water in 2007 for its terrestrial and ecology report was too short and inconclusive, putting species missed during the survey at risk.
“Approving the dam on the basis of this survey would be playing Russian roulette with the future of any number of endangered species,” he said.
