Morrison Government accidentally tells us more than it intended about its future plans for more dams?


Eighteen pages of 'talking points' compiled by the Prime Minister's Office were accidentally released to Australian journalists on Monday 14 October 2019.

These talking points predictably blame Labor in a look-over-there-not here manner, continue Scott Morrison's personal war on the poor and vulnerable and refuse to look climate change in the eye.

Interestingly for folks in the NSW Northern Rivers region, these points confirm federal government support for abandoning certain federal/state provisions contained in legislation covering water, environment and biodiversity when it comes to building new dams.

The document also lets the cat of the bag when it reveals a wider purpose behind building a Mole River dam in Tenterfield Shire.

The current proposal according the PMO is for a 100,000 megalites dam (basically the size of Karangi Dam in Coffs Habour LGA) which Morrison & Co see as assisting not just Tenterfield Shire but also as potentially useful to southern Queensland (See P.4). Morrison expects this dam to be 'shovel ready' two years from now, in 2021.

Water NSW released an Upper Mole River Dam fact sheet at the same time those errant talking points escaped inot the wild. This has the proposed Mole River dam as between 100 and 200 gigalites (ie., between 100,000 to 200,000 megalitres) and costing est. $355 billion. However, Water NSW does not see this proposed dam being 'shovel ready' until 2024 with dam construction completed sometime between 2026 and 2028.

Morrison's 100,000 megalitre dam would be ample to supply the needs of a NSW shire whose total population is yet to reach 7,000 residents, but is perhaps not entirely adequate to cover the needs of local irrigators into a future which is rapidly heating up and drying out.

So why would this such dam be thought capable of supplying water to southern Queensland and where would the potential additional 100,000 come from?

Water NSW data shows that Mole River catchment annual rainfall was less than 600mm in 13 of the last 18 years and, as Professor Quentin Grafton, water economist, ANU and UNESCO Chair in Water Economics and Transboundary Water Governance tells us, at 600mm or less annual precipitation a dam will not fill.

Perhaps the Mole River dam is only meant as a water storage staging post as much of the water capacity is intended to travel elsewhere?

Perhaps Prime Minister Scott Morrison and Minister for Water Resources David Littleproud are paving the way for a raid on a headwater tributary, the Maryland River, or on the Upper Clarence River itself - in order to forever pipe bulk water to Littleproud's electorate of Maranoa in southern Queensland?

Two local governments in Littleproud's electorate are lobbying hard for permission to pipe Clarence River water to their areas and, after all the Mole River is approximately 79kms as the crow flies from the headwaters of the Clarence River as well as less than 57kms in a direct line from Stanthorpe in Maranoa.
