There’s a story in today’s Age about Melbourne’s worrying water storage levels. However, the opening “claim” is little more than low-level sensationalism.
It starts off with these words:
MELBOURNE’S water storages are now 151 billion litres — or almost 10 per cent below where they were at the end of last winter, and householders should prepare for even tougher restrictions this summer.
While that’s true — it doesn’t reveal the whole story. Yes, the water issue remains as strong as ever. But making the claim above in the opening paragraph would have you believe we’ve been doing nothing as a community to save water, nor does it recognise this year’s good rains until much later in the article. You have to get to page two of the online article to find this:
Melbourne’s water storages had recorded levels either around or above their respective 30-year average winter totals already, (Melbourne Water spokesman Ben Pratt) said.
Melbourne’s water storages, at the start of 2007, were about 20 per cent below the January 2006 recordings. And they remained that way until mid-June, when our storages have picked up quite a bit. So — as of late August 2007 we are “almost 10 per cent below” — this means in fact we’ve closed the gap on 2006 levels by more than half.

(Compare the last 10 years of data on this Melbourne water storage graph page).
In other words, Melbourne’s rainfall and water usage patterns have resulted in us being at a better position than we would have been, had the 2006 trend continued after mid-June. In that case, our storage levels would presently be in the high 20 per cent range (around 28 per cent, not 38.5 per cent as they are as of 26 August 2007).
Of course, this doesn’t reveal the whole story either, as it’s only comparing the last two years of data. But it does reveal that this year’s trend is better than is being reported in this story in The Age.
