No doubt a headline event for the WA Watercorporation. There seems to be errors in the BoM map for example the 100% line should go west from Perth to the coast on basis Swanbourne and Rottnest – see data at AWN map. The brown area NNE of Wagin seems to lack data justification too in stations I can see at the CDO map. For large map.
Last February there was widespread heavy rain over SW Western Australia causing much flooding across many districts – Engineers Australia. Yet I can not see evidence that water was measured flowing into Perth dams. The rain for Perth catchments was mostly on the 10th Feb. I have kept screen shots of the “Rainfall at Perth Dams” page which has a running total of inflows but the total never varies in the days after the rain event.
Web footed Kiwis are emailing me as Christchurch and regions floods again. Whenever I have read NIWA Outlooks they seem utterly useless – does anybody get value for all the $Millions of Kiwi taxpayer dollars? Can anybody report where NIWA Outlooks have been accurate? Must get it right sometime.
Not claiming connections but all together make a blog.
Long Paddock for SOI – SILSO with a run of sun spot free days – July a better month for Perth and dam regions rain – further south.
Here we have one of the results of the GreenLabor Gillard Govt concocted Murray-Darling Basin scheme to waste 3,000GL of dam water in increased environmental flows and out to sea at Murray mouth. Murray-Darling Basin Plan: Taxpayer-purchased water intended for rivers harvested by irrigators – good on the irrigators.
The NZ climate prediction maestros look to have dropped another dodgy one – to my untrained eye anyway.
Stuff says – Live: Christchurch declares state of emergency, orders evacuation as floods rise – and the NZ Herald with hopeless front page – Winter storm chaos: What you need to know
If I read the COLA forecast right – more rain this coming week. Not long since – NIWA 3 month Outlook destroyed inside two weeks 11 Mar 2017
ABC reports – Perth Children’s Hospital: More delays as treatment fails to solve drinking water lead problem 30 Jun 2017 – I have blogged earlier this year. How have our Govts unlearned such a simple thing as a safe water supply?
Another of these cases where rain could have been enhanced by urban areas.
Main predicted dry core of Outlook exactly wrong – gotta love those Outlooks.
Forecast rain at BoM – Real world rain at BoM. Maps kept for posterity – April 2017 Outlook – Actual rain percentage.
The ABC reports – Perth Children’s Hospital (PCH) lead contamination in water pipes supplying site – my Dec 2016 blog “Australian Government financial disasters” was discussing this issue early this month. How slow it is for truth to emerge.
The WA Building Commission has reported on the lead contamination issue with an 83 page pdf – Final report – Perth Children’s Hospital audit. Analytical results are presented in a 3 page pdf – Test results – Perth Children’s Hospital lead level patterns. The crux of the Commission findings are on page 27 of the audit section in their must read 6.4.1 Findings. High metal contents were found in the “dead leg”, a 52m dead end length of pipe open to the QEII ring main see page – see page 34 for table of analyses. The location of the “dead leg” is shown on the page 22 map – note proximity to PCH offtakes. The Commission also suspects new brass fittings in PCH as another source of lead contamination.
Page 2 of the test results shows 4 charts labelled North-South-East-West Blocks of presumably the PCH. The South Block chart in lower left shows an increasing trend of lead content. I do not recall that being addressed.
