Tim Flannery must be running a close second to Paul Ehrlich by now. See the graphic first below about Perth's "declining" water supplies and after that a current picture of the Mundaring Weir in the Perth area (The difference between a weir and a dam is that water does not flow over a dam). Dam and weir levels are up in most of Australia at the moment. Fuller version of the first graphic here. The article has gone offline at its original source, "The West Australian" newspaper (originally June 25, 2004) but some pesky people keep copies of things. Tim should stick to fossils. He knows something about them.
A LONG spell of winter rain in Perth's catchment areas has lifted the city's dams to their highest level in almost a decade. Water Corporation spokesman Phil Kneebone today said the West Australian Government's winter sprinkler ban and consistent winter rainfall had helped fill dams to more than 49 per cent capacity. This compares with levels around 30 per cent before the seasonal winter rains arrived in June.
The Bureau of Meteorology said Perth and its surrounds had recorded rain on all but one day this month - the longest recorded stretch of daily September rainfall since 1915. However, this year's total rainfall of 536.8mm is still well below the city's average of 766mm to the end of September. A weather bureau spokesman said much heavier falls had been received in the catchment areas of the Perth hills and Mr Kneebone said he expected dams to rise above their current volume of 195.7 billion litres.
"I expect they will reach more than 50 per cent capacity by the end of the week," Mr Kneebone said. "It is easily the most water we have had in the dams, in any year, since 2000."
Mr Kneebone said the daily water consumption over the past week was down 16 per cent from this time last year. He said the sprinkler ban had directly contributed to a saving of 50 million litres of water a day, enough to fill about 22 Olympic swimming pools. "We currently have enough to get through an extra 50 hot summer days," he said. "It's great to see the community showing restraint with water use. "We will be able to give our biggest ground water source, the Gnangara Mound, a rest, which is also good news."
