Government Inquiry highlights worry over Gin Gin dam impacts

A parliamentary committee report looking at the controversial proposal to build a large ‘re-regulating’ dam in the Macquarie Rivers at Gin Gin was released today. The committee says they have ‘significant concerns about the potential negative ecological impacts’ of the proposal.

Community concern that WaterNSW won’t keep their hands off tributary inflows from below Burrendong dam is shared by the committee. The report says the lack of clarity regarding the use of tributary flows for water orders and how this will change as a result of the project is concerning.

“When this project was looked at as part of the Macquarie Priority Catchment Study, the plan was to take water from all sources. Now they say they won’t catch tributary inflows, but the economics of that doesn’t stack up. ” says Mel Gray, Convenor of Healthy Rivers Dubbo.

The committee heard that the best way to secure water for people and the environment is to improve the way water is managed in NSW.

The project poses a significant threat to remaining native fish populations in the Macquarie River. “The weir pool created by this dam proposal would destroy 32 km of habitat in and along the river. Population of threatened Murray Cod can’t bounce back after drought without habitat.” Said Ms Gray.

The report featured a warning from Professor Richard Kingsford that Australia is failing to meet its international obligations to protect Ramsar listed wetlands. Many waterbird communities are long-term decline as a result of historic water allocations and decreased river flows into major wetlands.

“There is certainly no environmental benefit of building that [Gin Gin] weir and there is a lot of risk in terms of downstream impacts, not just to the environment – the river – but also to the rural communities downstream.” Professor Kingsford was quoted as saying in the report.

Playing favourites on the floodplains

Floodplain harvesters’ use levee banks to divert water that either falls as rain or breaks out of the river bank during floods into private dams. It has been an unmeasured form of free water collection, believed to have increased since 1994 by almost two and a half times.

Floodplain harvesting has contributed to dehydrated floodplains and wetlands, less resilient rivers and depleted aquifers. It has contributed to the rapid decline in size and health of the Ramsar listed Macquarie Marshes, and has been identified in several reports as a key contributor to the mass fish kills in the Lower Darling in 2019.

The NSW Government have been touting that by licencing the controversial practice, they are bringing water take back in line with the Cap Limit on extraction set in 1994, and returning some critically important flood flows to the ailing river systems of the west.

However the Macquarie will be missing out on seeing any water returned to the valley, as the NSW Government – keeping true to their form of prioritising irrigation over everyone else – have increased the Cap Limit, and are claiming that floodplain harvesting can remain at current levels.

It is stated that the volume of the individual entitlements that have been arrived at is significantly inaccurate, and yet NSW still want to allow users to take five times their licence volume when a flood comes and gift them five times the water on their licence to get started. On top of that when the significantly inaccurate licence volumes are corrected, compensation will be paid.

“It is bewildering that the Government can wave a magic wand and claim less water is being taken now than in 1994, when we can see the wetlands, rivers and fish dying in front of our eyes.

“You would think the government would use the best available science and actual real life data to work out the volumes of these new licences seeing so much is at stake, but the modelling they used is rubbish.

“Despite having since 2008 to collect real data, the NSW Government have instead used secretive models to come with some rubbery numbers to convert into big, valuable, tradable, mortgageable compensable floodplain harvesting licences.

“We are being ripped off momentously. Our rivers and wetlands are being sacrificed as billions of dollars in property rights are being granted to an elite minority.”
