How will climate change affect Townsville’s water security?
This, the fourth post in our water security series, began as a response to the first of them, the Townsville Water Discussion Paper, and addresses an issue which none of the first three looked at. Parts 2 and 3 are here and here. This is a guest post by Malcolm Tattersall. Once again, views expressed are the author’s, not those of NQCC.
When I read Gail Hamilton’s post six weeks ago I agreed with nearly all of it but noticed a gap which was potentially important, i.e. the impact of climate change on our water security: the ‘Regional Water Supply Security Assessment’ from the Department of Water and Energy Supply (2014) (pdf here), upon which she relied for her ‘current situation’ section, didn’t consider climate change effects at all.
That seemed quite odd to me since we know that climate change is with us already on a global level – that most of the hottest years on record have occurred this century, that desertification is a key driver of conflicts in the Middle East, and that sea level rise is drowning low-lying islands and threatening major cities around the world. Some of us have also been feeling, on a much more local and personal level, that Townsville has been having weaker Wet seasons and hotter summers than ever before, and I happened to know, because I looked at it recently, that Bureau of Meteorology (BoM) data backs up our feelings.

This is the third part in a four-part series that discusses issues about water in our region. Read part 1 here. Read part 2 here. Part four asks how climate change will affect our region’s water security.
NQCC hosted a forum about the Hell’s Gate Dam feasibility study currently being conducted by Townsville Enterprise Ltd. NQCC was grateful to have the on-hand expertise of Patricia O’Callaghan (TEL CEO), David Lynch (principal economist for the study) and Jon Brodie (waterways expert). Here is what we were told about the dam and the study, plus questions that came from the audience.

This is the second part in a four-part series that discusses issues about water in our region. Read part 1 here. Part three is a summary report of information shared by Townsville Enterprise Ltd. about the Hell’s Gate Dam feasibility study at our forum that was held on 10 October. Part four asks how climate change will affect our region’s water security.

With Townsville in a drought and under Level 3 water restrictions, the public are asking a lot of questions. Water falls out of the sky so why does it cost so much? Why don’t we just build another dam? If the dams are on higher ground, then why does water have to be pumped?
Mainstream media in Townsville certainly muddies the waters by publishing half-truths and not publishing all the really important bits of information. Through a concerted media effort, the public has been led to believe that Hell’s Gate is the answer to endless and cheap water.

This is the first part in a four-part series that discusses issues about water security in our region. Part two explores dam infrastructure options, and part three is a summary report of information shared by Townsville Enterprise Ltd. about the Hell’s Gate Dam feasibility study at our AGM and forum. Part four asks how climate change will affect our region’s water security.
Townsville has an excellent water supply system, with highly treated and very safe water sourced from the Ross, Paluma and Burdekin dams.
While the Ross is our main supply dam, it is highly variable, with a limited catchment and low rainfall. The Paluma Dam is situated in the wet tropics and is much more reliable, but can only supply 30 ML per day. The Burdekin Dam is a huge system, with over 1 000 000 ML per year of water allocations, some of which is not committed. Townsville has 120 000 ML of allocation from the Burdekin.[1]
CURRENT SITUATION
In 2014, the Department of Energy and Water Supply undertook an assessment of Townsville’s water security.
